1. Oxygen Therapy Aaqid Akram MBChB (2013) Clinical Education Fellow

2. Objectives Understand the different oxygen delivery methods available Understand the amount of oxygen delivered with each delivery method

3. Nasal Cannula Variable Performance Range: 0.5-6litres/min Delivers: 1-2litres/min = 24% Add 4% for each litre added after this Be careful at higher flow rates as can cause mucosal drying.

4. Simple Face Mask Variable Performance Range: 5-10L/min Delivers: 35-60% Do not run at less than 5L/min –to prevent CO2 rebreathing

5. Venturi Mask Fixed Performance Delivers: 24%/28%/35%/40% Flow rate should be that marked on the valve With RR>30 increase flow by 50% Helps maintain minute ventilation Increases flow but not oxygen delivered

6. Non-Rebreathe Mask Variable Performance Range: 10-15L/min Delivers: 60-(80%)100% Always ensure reservoir bag is filled before putting on patient Consider humidification of oxygen due to high flow

7. Theramist Fixed performance device Cold water nebulised humidification Suitable for 28-60% O 2 delivery

8. Essential Points… Always remember to connect tubing to O 2 supply and turn Oxygen on Oxygen flow metre Set middle of ball to flow rate required If your patient is not tolerating the device: Review and alter delivery method, if possible Hypoxia kills quicker than hypercapnoea!

10. Non-Invasive Ventilation CPAP versus BiPAP

11. Objectives were: Understand the different oxygen delivery methods available Understand the amount of oxygen delivered with each delivery method
