Table 1 Tidal breathing parameters
From: Breathing variability—implications for anaesthesiology and intensive care
RR | Respiratory rate |
|---|---|
TI | Inspiratory time |
TE | Expiratory time |
Ttot | Total breath cycle time |
Ti/Ttot | Ratio inspiratory time: total respiratory time |
VT | Tidal volume |
VT/Ti | Mean inspiratory flow |
MV | Minute ventilation |
VE CO2 | Expired CO2 volume per breath |
FE CO2 | Mixed expired CO2 fraction per breath |
Fet CO2 | End-expiratory CO2 fraction |
