2020 Aug 17;6(3):00197-2020. doi: 10.1183/23120541.00197-2020. 6 What kind of device is an oxygen oxymizer? (1) This will deliver an inspired FiO2 which is fairly close to the set FiO2. Containing 95% pure oxygen, these disposable cans are easy to use and make a great back up for installed systems. in pneumonia). . The Oxymizer allows decreasing the patients liter flow while providing adequate oxygen saturation. Often a first-line sedative to allow tolerance of BiPAP within the ICU. This site needs JavaScript to work properly. A very common error is to try to treat a patient with drug intoxication (e.g. Overall, nasal masks seem to be less commonly used in critical care (and for the remainder of the discussion, BiPAP refers to the use of an oronasal mask). Haloperidol seems to be roughly half as potent as droperidol, but haloperidol can achieve similar clinical effects when dosed appropriately. Answer. Oxymizers might be the best-kept secret of respiratory therapy. Author: Claas Siegmueller. In a reservoir, the Oxymizer stores pure oxygen so that the concentration of inhaled oxygen is increased. 7). Lastly, there is a high-flow nasal cannula. Flow is delivered from one side only. Oxygen loss is negligible, but, with these devices, high concentrations of oxygen are not available. Haber H, Raber W, Kapfhammer G, Vetter N. Wien Klin Wochenschr. This can be done by using a device that takes . From a five-liter concentrator, you may get the equivalent of 7.5 litres. BiPAP achieves two things for these patients: The ePAP balances out AutoPEEP (positive pressure due to gas trapping in the patient's lungs). Nasal cannula is a device that helps deliver oxygen from an oxygen supply source (i.e. 3). The usual range of flow rate is ~20-60 liters/minute. Heliox will often reduce their work of breathing substantially. Nasal masks could potentially be an option for patients at high aspiration risk, especially if HFNC isn't available. ######, Choose a trusted medical devices supplier, 24-hour Continuous Blood Pressure Monitoring, Benign paroxysmal positional vertigo (BPPV). Oxygen delivery devices. MeSH Meanwhile commodity high flow oxygen products provide oxygenation support. Oxygen Delivery Devices 1. With aiming to minimize condensation, manufacturers have developed various types of inspiratory circuits, of which, the most widely adopted type is a circuit that simply contains a heating wire. Adult Respiratory. ; p<0.05). Abstract. When you need to take a bath/shower, switch to a regular nasal cannula. These devices are designed specifically to optimize both breath triggering and leak compensation. Enter multiple addresses on separate lines or separate them with commas. Oxygen is supplied via a low-pressure system, while the device monitors oxygen concentration. When in doubt, a reasonable approach is often to support the patient on BiPAP while simultaneously preparing for intubation. Note that a standard nasal cannula at 6 liters/minute can provide ~40-50% FiO2, so patients may be ready to transition to a low-flow cannula earlier than may be obvious. Even during quiet breathing, inspiratory flow rates are approximately 30 liters per minute, which exceeds supplemental oxygen flow (3). A: Optiflow nasal prongs and inspiratory circuit are both large bore. The Oxymizer device is a special oxygen nasal cannula that provides a higher luminal diameter in combination with an incorporated oxygen reservoir. Print ISSN: 0020-1324 Online ISSN: 1943-3654. 4. It is assumed that a higher O2 concentration can be delivered breath by breath in order to increase oxygenation. 2018 Dec 24;115(51-52):871-877. doi: 10.3238/arztebl.2018.0871. 5. Allows unimpaired ability to communicate (facilitating patient assessment). So if you were breathing with a normal peak inspiratory flow rate of 30 L/min but were receiving 30 L/min of pure oxygen via a high flow oxygen delivery device, you do not need to suck in any more air from the surrounding atmosphere and would be receiving a FiO2 of 100%. (a) Mental status: Patients with depressed mental status are at increased risk of aspirating. 8600 Rockville Pike We are the EMCrit Project, a team of independent medical bloggers and podcasters joined together by our common love of cutting-edge care, iconoclastic ramblings, and FOAM. Improving longevity and quality of life in hypoxemic patients. Long-term oxygen therapy for COPD. Nan. Devices delivering high-flow nasal oxygen are dicussed elsewhere. While the patient is exhaling, oxygen flowing from the tank will accumulate in the oxygen reservoir. The tubing is much larger and less supple than "normal" cannulae. B: Optiflow. High flow is generated through air entrainment constriction; equipped with a flow meter and oxygen analyzer. The Oxymizer effectively oxygenates high-flow patients. The non-rebreather has valves. One of the last items you talked about was that a lower temperature may be more comfortable for the patient but that we also have to balance that with using an appropriate temperature that carries the right amount of humidity to the patient. Furthermore, there was a positive correlation (r = 0.427, p = 0.002) between the O2 flow rate and improvements in the constant work rate test, showing greater improvements in favor of the Oxymizer in patients with a higher demand for O2 ( 4 liters/min). Thus it is assumed that a higher oxygen content can be delivered in order to increase oxygenation. 1 What is the difference between an Oxymizer and nasal cannula? It has a built-in humidification feature. HFNC is arguably front-line therapy for patients with parenchymal lung disease (e.g. (2) Pneumonia with marked tachypnea (reduction in respiratory rate may prevent the patient from tiring out). The .gov means its official. The lower the ambient temperature, the more likely there is to be condensation. Delivers up to a 4:1 savings ratio. This needs to be successfully addressed to provide optimal care for patients. What is the maximum nasal cannula flow rate? Abstract. Easier to perceive facial expression & speak with the patient. This method can provide flow rates up to 60 L/min and FiO2 of 21% to 100%, irrespective of the flow rate. How is this possible? 60 liters/minute). 2009;6(9):111 Bailey It is composed of a flow meter and oxygen concentration monitor. eCollection 2018. Normally the anatomic dead space extends from the respiratory bronchioles to the mouth (the site of fresh gas exchange). In our ICU, we usually set it to 37C, mainly because most of our patients accept that setting. The maximal flow rate varies, but it can be excessive. May prolong QT and cause Torsades de Pointes (but the risk is extraordinarily low at the doses used for mild sedation). Apart from the physical differences of each device, the primary difference is that face masks allow higher concentrations and rates of flow of oxygen. The Oxymizer device is a special oxygen nasal cannula that provides a higher luminal diameter in combination with an incorporated oxygen reservoir. CharlesH, dustybill, Kandy State Captain of South Dakota and 12 other people care about this. The Mustache Oxymizer is a Fluidic Oxymizer. Aim of this prospective cross-over study was to investigate the effects. It is the simplest conserving device available today, operating without electronics, batteries, switches or flow controls. If HFNC is available, then HFNC is generally superior to venturi masks or non-rebreather face-masks (especially for. With conventional humidifiers, clinical event incidences, patient arousal, crying, and desaturation were higher. We do not capture any email address. The goal is a flow rate ~40 liters/minute, which will achieve a FiO2 very close to 100%. HFNC is more comfortableand studies have shown that using HFNC may be a better alternative than using a face mask. ii) For patients with refractory hypoxemia, increasing the flow could theoretically increase the oxygenation a wee bit (due to PEEP). How to Market Your Business with Webinars? Epub 2017 May 16. Providing Optimal Humidity for intubated patients. All settings are controlled independently, allowing for greater confidence in the delivery of supplemental oxygen as well as better outcomes when used. Each of these flow generators also generates noise, which increases with flow. Requirement for immediate intubation (e.g. . They can deliver up to 60 liters of oxygen per minute. A recent trial published in the American Journal of Respiratory and Critical Care Medicine compared high-flow oxygen (HFO) therapy with oxygen administration via a Venturi mask after extubation . An official website of the United States government. We do not capture any email address. The Chad Oxymizer Disposable Oxygen Conserver offered by Drive Medical facilitates the delivery of continuous high-flow oxygen therapy. 8). endstream endobj startxref 2015 Apr;60(4):540-8. doi: 10.4187/respcare.03647. 4 What is the flow rate for a nasal cannula? facial trauma or burns). NOTE: We only request your email address so that the person you are recommending the page to knows that you wanted them to see it, and that it is not junk mail. In other situations, it may be wise to transition to HFNC if there are difficulties tolerating BiPAP. Currently the helmet interface isn't widely available in the United States. Bookshelf High flow can thus be generated even though air and high-pressure oxygen wall supplies are unavailable. CPAP will reduce preload and afterload, exerting a physiologic effect which is similar to an ACE inhibitor. The normal fraction of inspired oxygen (FIO2), or concentration of oxygen in the air, in any room is about 21% . perhaps roughly 30-50 l/m). Conclusion: This study showed that oxygen delivery via Oxymizer is superior to CNC with regards to endurance capacity and a better oxygenation during exercise in patients with severe COPD. RCTs on patients with heart failure and COPD have shown that BiPAP reduces intubation rates and mortality among sicker patients. In a number of critical care ventilators, a HFNC capability is integral to the machine. They complain a lot more that it's too hotthat might just be the patients with COPD because they're the ones who like fans blowing and air moving in the room. By contrast, with the Optiflow system (Fisher & Paykel), the nasal prongs and tubing between the nasal prong and inspiratory circuit are both large bore, and flow to the prongs is delivered from one side only (Fig. Koczulla AR, Schneeberger T, Jarosch I, Kenn K, Gloeckl R. Dtsch Arztebl Int. Of course, in many cases this amount of benefit might be small and thus clinically insignificant. $22.37. The https:// ensures that you are connecting to the COPD patients with pH < 7.30). For example, there's probably no form of respiratory failure which wouldn't derive. Disclaimer, National Library of Medicine This question is for testing whether or not you are a human visitor and to prevent automated spam submissions. 4. A high ePAP will maintain high intrathoracic pressures throughout the respiratory cycle, which will off-load the heart. There was a significant difference in favour of high-flow nasal oxygen in 90 day mortality (Frat et al, 2015; FLORALI study) Preoxygenation and apnoeic oxygenation Compared to HFFM (high flow face mask), HFNC as a preoxygenation device did not reduce the lowest level of desaturation in an RCT (Vour'ch et al, 2015 - PREOXYFLOW trial) There are 3 types of standalone flow generators: air-oxygen blenders, built-in flow generators, and entrainment systems (Fig. Perhaps temperature is more patient specific, and, again, it all comes back to perhaps we should interact more with our patients to say does this feel too hot? Most devices have the option to choose lower temperatures, they may not be the ideal temperature, but it's what the patient would prefer. The Oxymizer can be used with compressed gas cylinders, concentrators, and liquid oxygen. Reservoir tubing An Oxymizer mustache or pendant can increase the amount of oxygen delivered or make the oxygen last longer. naloxone). The patient determines the respiratory rate, the length of each breath, and the flow rate. doi: 10.1371/journal.pone.0209069. The bag must always be kept half-inflated. However, in a subgroup analysis we found that patients with an oxygen supplementation of 4 liters/min obtained an markedly higher increase in exercise capacity by using the Oxymizer than patients with lower oxygen flow rates (increase in endurance time 161225 sec. OxyMASK The Oxymask device allows for a much higher flow rate (15 L/min or more) and can achieve higher FiO2 levels at the same L/min as the Nasal Cannula. Find clinical evidence and practice guidelines for delivering nasal high flow (aka HFNC) therapy. The Oxymizer device is a special oxygen nasal cannula that provides a higher luminal diameter in combination with an incorporated oxygen reservoir. For now, although functional differences among the different HFNC systems seem to be minor, to avoid adverse clinical events, it is essential to know the advantages and disadvantages of each element. Oxygen therapy ensures the lungs are fully saturated so that a patient can maintain oxygen levels in their blood. These are widely used, but probably aren't the best agents (unless the patient was previously on benzodiazepines and is known to respond favorably to them). Provides a comfortable alternative to a mask, allowing patients to eat, drink and talk. Thank you for your interest in spreading the word on American Association for Respiratory Care. The use of ventilator-triggered breaths in. Although ease of application cannot be matched by . The y-axis shows noise level (dB) and x-axis displays settings (flow/FIO2). FiO2 is defined as the percentage or concentration of oxygen that a person inhales (the fraction of inspired oxygen). Background: The Oxymizer device is a special oxygen nasal cannula that provides a higher luminal diameter in combination with an incorporated oxygen reservoir. Venous blood gas is entirely adequate in nearly all cases (unless the VBG oxygen saturation is. A couple breathes of Oxygen will help bring you back up. Tel(852) 2402-2188 Fax(852) 2411-2323 Business Hours: Mon-Fri: 09:00 18:00 Sat: 09:00 16:00 Sundays & Public Holidays: Closed, Unit 702, Grandmark, 10 Grandville Road, Tsim Sha Tsui. We always start at 37C because it's our normal body temperature and it's what our cilia in our airway require to be able to function properly. Some mode of ventilatory monitoring should be employed in patients receiving opioids (e.g. patients receiving sedation to tolerate the BiPAP). Your email address will not be . Images courtesy Fisher & Paykel Healthcare and Vapotherm. Careers. As flow increased, noise level got louder. High-flow oxygen therapy is applied with a special binasal high-flow nasal cannula (HFNC), and a heated inspiratory breathing circuit. Average flow rates for . Face-Mask Oxygen. cardiac arrest). Noise is an important consideration. Many times, the terms high-flow and high liter flow all get mixed. MacGyver's HFNC can be used in emergencies when patients are desaturating and need more FiO2 immediately. Too much oxygen can be damaging to the patient's health, and it can result in the patient becoming dependent on high levels of oxygen. With HFNC, the anatomic dead space extends from the respiratory bronchioles to only the mid-tracheal level (since fresh gas is being pumped into the upper airway). This is the most widely used mode of noninvasive support. Images courtesy Fisher & Paykel Healthcare and Vapotherm. Oronasal masks are usually tried first, but many patients find them too uncomfortable to tolerate. The high-velocity nasal insufflation system (Hi-VNI, Vapotherm) uses a slender nasal cannula similar in appearance to a regular nasal oxygen cannula. Just wondering if you had found it to be useful, or not. Patients can be weaned down to a conventional low-flow nasal cannula when appropriate (usually 1 to 6 L/minute or per . There is no need to check an ABG to measure the pO2, if the patient has a functioning pulse oximeter (more on this. Dry gas is known to have diverse adverse effects on the respiratory system, such as mucociliary malfunction, epithelial damage, mucus plugging, ulceration of mucosa, and lung injury.28,29 At flows of up to 60 L/min, HFNC delivers medical gas, usually through a heated humidifier incorporated into the delivery system. Basically holes with a plastic cover over them. eCollection 2020 Jul. (2) An increase in the pressure when the patient triggers a breath (the inspiratory Positive Airway Pressure, or iPAP). Heart failure and COPD are somewhat unique in this chapter, as situations where there is a definitive front-line therapy. Increase the flow on the concentrator until you are at the maximum. The noise level of the MaxVenturi was loudest among the systems, regardless of settings. Invasive Ventilation. For example: BiPAP provides the greatest amount of mechanical support for the work of breathing. endstream endobj 338 0 obj <>>> endobj 339 0 obj <>/ExtGState<>/Font<>/ProcSet[/PDF/Text/ImageC]/XObject<>>>/Rotate 0/TrimBox[0.0 0.0 612.0 792.0]/Type/Page>> endobj 340 0 obj <>stream Other examination findings may reflect work of breathing (retractions, tri-podding, ability to speak in sentences, the patient's perception of their breathing). Jet flow is noisy. and indication for long-term oxygen therapy were recruited during pulmonary rehabilitation. https://t.co/dSCecbiMQA, Richard Levitan (@airwaycam) December 12, 2019. (1) It will reduce the respiratory rate which can be helpful for patients with marked tachypnea (if the tachypnea and increased work of breathing are themselves detrimental). The patient must be able to be weaned off noninvasive respiratory support within a few hours. B: SLH. Placing a plastic sleeve around the circuit can insulate the limb exterior from cooler ambient air and decrease condensation.36 More sophisticated circuits have recently been developed. For example, if a patient requires a 2 lpm setting, the Oxymizer allows you to lower the flow to 0.5 lpm without compromising oxygenation. The primary outcome of our study was to evaluate the effect of the addition of a surgical mask on a high-flow nasal cannula system on oxygenation parameters in . Beyond the circuit, condensation may also accumulate in the nasal prongs, which results in water droplet spray into the nostrils. N=43 patients with severe COPD (age: 609y, FEV1: 3716% pred.) The easiest way to describe it is that high velocity therapy is Mask-Free NIV, and offers ventilatory support for patients in respiratory distress, including hypercapnia, hypoxemia, dyspnea, respiratory distress secondary to other medical conditions. there are considerable inter-individual variations, for example regarding claustrophobia and secretion volume). Sign In to Email Alerts with your Email Address. I Care. A: The AirSpiral (Fisher & Paykel) breathing tube uses heating wires embedded in the circuit wall to keep wall temperature high enough to avoid condensation. I prefer to use 37C. Lower risk of skin ulceration (avoids placing pressure over the bridge of the nose). The goal of noninvasive respiratory support is essentially to support the patient long enough for other therapies to work (e.g. The goal of noninvasive respiratory support, In order to be effective, all of these techniques must be applied. This high flow can provide more constant inspiratory oxygen . In a reservoir, the Oxymizer stores pure oxygen so that the concentration of inhaled oxygen is increased. Thank you for your interest in spreading the word on European Respiratory Society . It is a 10-liter machine with the smallest profile. Rather than using a heating wire inside the circuit, warm water runs between the inner and outer lumens of the tubes through which medical gas is delivered. This question is for testing whether or not you are a human visitor and to prevent automated spam submissions. At high-flow nasal cannula (HFNC) flow of 20 L/min, when VT increased from 300 to 700 mL, absolute humidity decreased; at HFNC flow of 40 and 50 L/min, absolute humidity did not vary according to VT. A: AIRVO 2. Air-oxygen blender with a flow meter is the most common. For any given flow rate (e.g. That's really the only patient population I've seen that complains about the heat being too hot, and we'll turn it down for them a little bit. These are devices which are designed for outpatient therapy of sleep apnea or obesity hypoventilation syndrome. These systems use air-entrainment or blending systems to create precise Fi02. Its quite simple. @ o; Noninvasive respiratory support is best suited to patients with isolated respiratory failure. iii) Gastric distension on imaging studies (including point-of-care ultrasonography) could conceivably be used to gauge risk. Can be widely applied, to a variety of disease processes. Allow for secretion clearance, if that is an issue (e.g. Aim of this prospective cross-over study was to investigate the effects of the Oxymizer in comparison to a conventional nasal cannula (CNC). However, the reported FiO2 that is delivered is not always accurate. The underlying diagnosis is more important than the ABG values in determining how to treat the patient. In these cases, the ventilator allows control of FIO2 and flow while using the heated humidifier commonly connected to the ventilator. The patients were much more comfortable when we turned down the temperature on the heated high-flow nasal cannula. The Oxymizer pendant is a special oxygen cannula that can be used to supply high flow long term oxygen therapy. However, many patients with somnolence due to hypercapnia will do fine on BiPAP. There is fairly compelling evidence to support the use of noninvasive respiratory failure in asthma. Background: Nasal Continuous Positive Airway Pressure (NCPAP) has been the mainstay for non-invasive respiratory support for at risk neonates. Featuring under nose NIV masks (F&P Visairo) and full face NIV masks - (F&P Nivairo . An oxygen oxymizer is a device used to reduce the amount of oxygen in air. Features a built-in humidification effect. high-flow nasal cannulas), while at rest and during rapid breathing. Thus it is assumed that a higher oxygen content can be delivered in order to increase oxygenation. When in doubt, empiricism is king here: empirically trial the low-flow nasal cannula. However, the following points should be stressed: Want to Download the Episode?Right Click Here and Choose Save-As. A Venturi mask is also able to prevent carbon dioxide retention, which can help avoid hypercapniaand the suppression of the respiratory drive. Abstract Background: The Oxymizer is a special nasal cannula that provides a higher luminal diameter in combination with an incorporated oxygen (O2) reservoir. This device should be considered if a flow rate above 6L/min is needed (or 4L/min for more than 15 minutes) to return to the patient's baseline. official website and that any information you provide is encrypted 1990 May 25;102(11):325-9. No real risks (aside from potentially delaying intubation). What do you need to know about the oxymizer pendant? However, the design of the Salter 1600 allows for . An oxygen oxymizer is a device used to increase the amount of oxygen in air. In general, air-oxygen blenders titrate oxygen concentration according to the amount of medical gas inhaled; some gas is lost via the blender. Both AIRVO 2 and Optiflow delivered appropriate levels of absolute humidity, except at 20 L/min with Optiflow. For example, use of heating wires embedded in the circuit wall keeps the wall temperature high enough to avoid condensation (Fig. The Oxymizer device is a special oxygen nasal cannula that provides a higher luminal diameter in combination with an incorporated oxygen reservoir. COPD. Units 1-3, 4th Floor, Wing Ming Industrial Centre, 15 Cheung Yue Street, Lai Chi Kok. The Oxymizer increases the proportion of oxygen flow . A: RT202. (2) Some may be unable to generate high flow rates (leaving the ventilator unable to provide enough support for a very dyspneic patient). Once this becomes available, it will be a useful tool to add to our noninvasive ventilatory support toolbox. Increase to 18 cm inspiratory pressure / 5 cm expiratory pressure. Facilitates the delivery of continuous high-flow oxygen therapy in a homecare, hospital, hospice or long-term care setting. antibiotics, bronchodilators, steroids). Short-term solution (patients will wake up within ~30-60 minutes). This is a general cognitive rubric for how to select different devices. Benefits of a reservoir nasal cannula (oxymizer) versus a conventional nasal cannula during exercise in hypoxemic COPD patients, Self-management education using interactive application software for tablet computer to improve health status in patients with COPD: A randomized controlled trial, Early supported discharge/hospital at home for exacerbation of chronic obstructive pulmonary disease, A review and meta-analysis, Frequency of adverse consequences after spirography in patients with chronic obstructive pulmonary disease and concomitant ischemic heart disease. Schneeberger T, Leitl D, Gloeckl R, Jarosch I, Reimann D, Hitzl W, Koczulla R, Kenn K. ERJ Open Res. One common method of heating and humidifying gas is through pass-over humidification, where breathing gas passes over highly heated water to add moisture and humidify the gas. Patients with acute respiratory failure due to pleural disease require emergent pleural drainage. Therefore, Heliox. i) Active or recent vomiting is probably the strongest risk factor. For a patient with undifferentiated stridor, Heliox may be used to buy time while obtaining materials and colleagues needed for definitive management (e.g. (b) Patients with central sleep apnea, who benefit from, (c) Ventilator-triggered breaths are excellent for supporting respiration during the apneic period of rapid sequence intubation (more on this. This may be worthwhile for patients with a highly BiPAP-responsive disease process (section above). Severe pleural disease can cause frank respiratory failure. Possibly the agent with the greatest amount of evidentiary support. I think your observation is important because we have these humid summers with weather warnings for people with chronic respiratory disease not to go outside. Vapotherm provides a filter-type humidifying system. Both AIRVO 2 and Optiflow delivered appropriate levels of absolute humidity, except at 20 L/min with Optiflow. Because the peak inspiratory flow rate of a resting individual is typically below 30 L/min, 2 delivering oxygen at higher flow rates (eg, 45 L/min) precludes contamination of oxygen within the facemask with room air, so that the effective FiO 2 is close to 1.0. It's impossible to predict exactly how any specific patient will respond to a given therapy. H -"\ZEGr7pz1@a/ C%DD82NL R\ FU JHCh1*2V @'@62[F:8iBCH@qQc6If|zIV9bEL26?U. As FIO2 increases, air entrainment decreases; however, the required rise in oxygen flow to keep the total flow constant also generates more noise. A partial rebreather mask has side ports that are covered with single-way discs that prevent . If you continue to use this site we will assume that you are happy with it. A simple face mask can deliver oxygen concentrations from 40 to 60% at flow rates between 10 to 12LPM. Details. Change back to the pendant when finished. Depending on the device, they may not compensate well for gas leaks around the mask. This system prevents cooling from ambient air and decreases the amount of condensation in the inspiratory circuit.39 It is an application of almost identical systems that are used for warming blood or infusion fluids (Fig. ROX Index 4.88 measured at 2, 6, or 12 hours after high-flow nasal cannula (HFNC) initiation is associated with a lower risk for intubation. 2. *Due to the oxygen storage capability of the Oxymizer, you can reduce your patient's liter flow and still deliver the required amount of oxygen to maintain saturation. Methods: Patients were randomized to either protocol A (n = 25; HFFM followed by HFNP) or protocol B (n = 25; HFNP followed by HFFM) after a stabilization period of 30 minutes after extubation. In heart failure, CPAP is as effective as BiPAP. This site represents our opinions only. A recent advance in oxygen delivery technology is high-flow nasal prongs (HFNP). Accessibility 2 How many liters of oxygen are in a Oxymizer? High-flow oxygen (HFO) consists of a heated, humidified, high-flow nasal cannula that can deliver up to 100% heated and humidified oxygen at a maximum flow of 60 LPM via nasal prongs or cannula. Flow is titrated by adjusting jet flow outlet. However, nobody really cares. This can be helpful for those who need more oxygen to breathe or for businesses that need to produce less air without sacrificing quality. Laura Duggan @drlauraduggan schooled me on this. Expiratory pressure (ePAP) is the key here. The optimal strategy for setting BiPAP is unknown (and in all likelihood, no universally applicable strategy exists). Please enable it to take advantage of the complete set of features! Beside of a longer cycling duration, PaO2 values at the end of CWRT were also significantly higher with Oxymizer (6511 mmHg versus 6210 mmHg; p<0.001).
