The evidence review methodology has changed from NICE methodology to the BTS NICE accredited guideline production process which is based on the Scottish Intercollegiate Guideline Network (SIGN) methodology and adheres to AGREE methodology (see section 1).

You can read more about our editorial guidelines and our oxygen concentrator methodology for the rankings below. For example, you may only need oxygen treatment for short periods during the day when you’re walking about (ambulatory oxygen). It also covers short-term oxygen use by healthcare workers outside of healthcare settings, but domiciliary oxygen use by patients is covered by the BTS Guideline for home oxygen use in adults.Other portable oxygen systems are available to meet a wide range of oxygen needs and individual circumstances.

For most patients who require blood gas sampling, either arterial blood gases or arterialised earlobe blood gases may be used to obtain an accurate measure of pH and PCO 2. It’s difficult to obtain as high of a blood oxygen concentration with a partial rebreather since the oxygen concentration in the reservoir bag becomes diluted. High supplemental oxygen can result in Oxygen Toxicity, whereas insufficient oxygen saturation can result in hypoxemia.Audits of oxygen use and oxygen prescription have shown consistently poor performance in many countries, and most clinicians who deal with medical emergencies have encountered adverse incidents and occasional deaths due to underuse and overuse of oxygen. A partial rebreather mask looks similar to a non-rebreather mask but contains a two-way valve between the mask and reservoir bag. The most notable use of this metric is in the Berlin criteria, which categorizes ARDS as mild (201to 300 mmHg), moderate (101to 200 mmHg), and severe (less than 100 mmHg).

While choosing to purchase a double battery pack increases the device’s cost and weight, it also increases its battery life to 13 hours when used on the first flow setting.

If you use a continuous flow portable oxygen concentrator, that could mean traveling with an additional 20 to 30 pounds of batteries, says Bacheler. Not adhering to facility protocols for liter flow amounts can cause dangerous levels of CO2 to build up inside oxygen face masks. Such patients are given oxygen-enriched air in these cases, usually having FiO2 higher than the normal air.

Meanwhile, keep in mind that because portable oxygen concentrators use rechargeable batteries, it’s important to carry an extra battery whenever you anticipate being away from home for long stretches of time. Recent evidence suggests that, if impaired gas exchange does actually develop, this practice may actually place patients at increased risk (see full Guideline section 6.You may also be asked to do an exercise or a walking test to check if you'll benefit from home oxygen therapy. Continuous positive airway pressure (CPAP) with entrained oxygen or high-flow humidified nasal oxygen to maintain saturation 94-98% (or 88-92% if at risk of hypercapnia) should be considered as an adjunctive treatment to improve gas exchange in patients with cardiogenic pulmonary oedema who are not responding to standard treatment (or non-invasive ventilation (NIV) if there is co-existant hypercapnia and acidosis) (grade B).
