Patient Factors & Considerations
N / A
COVID-19 / Febrile Respiratory Illness
Crews are advised to limit the use of oxygen in patients with influenza like symptoms wherever possible to avoid aerosolisation.
Crews are advised to tolerate lower SpO2 than usual in patients with ILI; ≥ 88% is acceptable. Note: It may not be possible to improve SpO2 to an acceptable level within the oxygenation guideline described above.
Recommendations:
Nasal prongs: 1-4 litres per minute, ideally with surgical mask over the top where possible
Therapy mask: Maximum 10 litres per minute
Non-rebreather/high concentration mask: Maximum 15 litres per minute
Crews treating patients who are on home BiPAP/CPAP or with a tracheostomy should don full PPE requirements for aerosol generating procedures (AGP’s) if the presentation is an infective respiratory illness. See PPE requirements.
Always turn the oxygen off first, thenremove the nasal prongs/mask from the patient.
Procedure
All relevant infection control methods to be utilised.
Select appropriate size and type of face mask required, either nasal cannula[1], the therapy mask[2] or the non-rebreathing mask[3].
Nasal Cannula
Connect the face mask to the oxygen cylinder.
Set flow rate at 1 to 4 litres per minute.
Apply the nasal cannula to the patient's nose first; if the nasal prongs are curved, these should face posteriorly to the patient.
Looping the tubing around the patients ears and bring it to the front of the patients chest.
Move the slider up the tubes to adjust the fit. The nasal cannula should sit snugly under the chin with enough room to fit two fingers between the tubes and the patients chin.
