1
Q
define:
SpO2
A
Saturation (s) of the Partial Pressure (p) of Oxygen (O2)
Tells you about oxygenation in periphery where reading is taken from
2
Q
define:
EtCO2
A
End-Tidal (et) Carbon Dioxide (CO2)
Tells you about ventilation in the lungs
3

6
Q
How does EtCO2 work
A
Measures he concentration of CO2 molecules at the end of expiration that absorb infrared light
7

A
Respiratory baseline
Expiratory upstroke
Expiratory Plateau
End tidal value - peak CO2
Inspiratory down stroke
