3
Q
What are the oxygen saturation targets?
A
Acutely ill: 94-98%

O2 should be reduced in stable patients with satisfactory O2 sats
4
Q
How should COPD patients be managed?
A
28% Venturi mask at 4L/min + aim for 88-92% if RFs for hypercapnia but no prior hx of respiratory acidosis
Adjust target range to 94-98% if pCO2 is normal
