SpO2 Monitoring
SpO2 refers to peripheral monitoring; SaO2 refers to aterial monitoring
Limitations of SpO2:
vascular dyes like methylene blue can lead to low readings
bright lights, edema, nail polish may interfere with the photodetector
incorrect placement may allow light to reach photodetector without passing though Hb
Abnormal Hb may falsely elevate spO2

EtCO2 Monitoring
EtCO2: measures ventilation based on CO2 [ ] throughout the ventilatory cycle
Normal: PaCO2 may be 1 - 5 mmHg > PetCO2
PetCO2 (end tidal CO2) is a reliable alternative to PaCO2 (partial pressure of arterial CO2) in hemodynamically stable patients.
