Question

If you intended to counter oxygen depletion by emergency aeration, how would you choose the oxygen concentration at which to begin aeration ?

Answer 1

Oxygen needed in case of hypoxic and breathing difficulty patient with acute hypoxemia, it is must target the saturation range above 90%. patient with critically ill they need high concentration oxygen to avoid oxygen depletion and acute hypoxia. O2 saturation can be 88% in the case of hypercapnic respiratory failure. Adequate oxygen content(Cao2) of blood and arterial carbon dioxide(Paco2) should be raised. Using a 28% venturi mask at 4L/min or 24% venturi mask at 2-4L/min in a hospital setting as an initial target and target oxygen saturation can be 88-92% is recommended. oxygen dosage should be reduced if oxygen saturation is above 92%or more.
