if CO2 ↑ above 6kPa get senior help
2
Q
what O2 to give a critically ill patient?
A
15L/min (non-rebreathe mask) 85-90%
reassess if oximetry sats <3% target range
3
Q
what CO2 to aim for in COPD?
A
88-92%
4
Q
who at risk of ↑ CO2 and therefore should have sats 88-92%?
how to give O2?
A
COPD CF bronchiectasis NM disease chest wall morbidly obese
- 24%, 28%, or 1-2L/min nasal oxygen
- if pH still low, NIV + senior
