Sudden cessation of supplementary oxygen therapy can cause life-threatening rebound hypoxaemia with a rapid fall in oxygen saturations below the starting oxygen saturation prior to the start of supplementary oxygen therapy.

The key aim of this guideline is to make oxygen use in emergency and healthcare settings safer, simpler and more effective. Oxygen is probably the commonest drug used in the care of patients who present with medical emergencies. Prior to the publication of the first British Thoracic Society Guideline for Emergency Oxygen Use in Adult Patients in 2008, 1 ambulance teams and emergency department teams were likely to give oxygen to virtually all breathless or seriously ill patients and also to a large number of non-hypoxaemic patients with conditions such as ischaemic heart disease or stroke based on custom and practice. About 34% of UK ambulance journeys in 2007 involved oxygen use. 4 This translated to about two million instances of emergency oxygen use per annum by all UK ambulance services, with further use in patients' homes, GP surgeries and in hospitals. 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. 5–11 The medical history should be taken when possible in an acutely breathless patient and may point to the diagnosis of a particular acute illness such as pneumonia or pulmonary embolism or an exacerbation of a chronic condition such as COPD, asthma or heart failure.

SUMMARY OF KEY RECOMMENDATIONS FOR EMERGENCY OXYGEN USE

Bandra Branch If the patient uses a venti mask for oxygen, the flow meter is always set at 15 liters. The mask has different color-changeable plastic pieces. Besides, each color signifies a different oxygen delivery percentage. Being said that, it can deliver between 24 to 50 percent of oxygen. J5. Constant clinical assessment of the patient is crucial at all stages of conscious sedation procedures and monitoring of capnography or transcutaneous carbon dioxide levels may be a useful adjunct to identify early respiratory depression (grade D).

Oxygen delivery devices such as a nasal cannula, venturi mask, and high-flow nasal cannula can deliver varying FiO2. A patient breathing ambient air is inhaling a FiO2 of 21%. Oxygen delivery devices determine the flow rate and FiO2 based on predicted equipment algorithms. The conventional prediction model states that for every liter of oxygen supplied, the FiO2 increases by 4%. Therefore, a nasal cannula set at a 1 L/min flow rate can increase FiO2 to 24%, 2 L/min to 28%, 3 L/min to 32%, 4 L/min to 36%, 5 L/min to 40%, and 6 L/min to 44%. Low-dose opioids should be considered because they are effective for the relief of breathlessness in palliative care patients. F15. In most poisonings, aim at an oxygen saturation of 94–98% unless the patient is at risk of hypercapnic respiratory failure (grade D). Do not keep patients on 15L for longer than necessary as over-oxygenating for prolonged periods can be harmful. Oxygen saturation and delivery system (including flow rate) should be recorded on the patient's monitoring chart.

Oxygen percentage is simply the percentage of oxygen in the air. Typical air consists of about 21 percent oxygen and 78 percent nitrogen, with other trace gases making up the other one percent (including neon, hydrogen, and carbon dioxide.) So, this means that typically without supplemental oxygen you’re breathing in 21 percent oxygen. Use of oxygen by voluntary rescue organisations and other non-National Health Service first responders.
