Mode of Oxygen Delivery

We can divide the mode of O2 delivery into 2 types ;

1. Fixed ---- i) Intubation ii) High Flow Mask (HFM) @ Venturi Mask

2. Non-fixed ---- i) Nasal Prong ii) Face Mask

Fixed - the amount of O2 concentration that is given to the patient is fixed as the patient do not need to put effort to breath.

Non-fixed - the amount of O2 concentration given to patient is not fixed as patient breath in the room air together with the O2 given, so the amount of O2 inhale varies with the patient's breathing effort

1. Nasal Prong - can give up to 3L/m of O2 and also up to 30% of O2 concentration

2.Face Mask - can give up to 12-15L/m of O2 and can give up to 40-50% of O2 concentration

3. HFM - can give up to 15L/m with fixed O2 concentration of 40-60%

4. Intubation - gives a fixed O2 concentration of 100%


Factors that influence the delivery of O2 to tissue ;
1. Hb amount
2. O2 saturation
3. Tissue perfussion

** Any mistakes, plz let me noe so that i can make the changes... thx
