Tidal volumes and respiratory
frequencies (cycles per minute)
The follwing frequencies and tidal volumes are ob-
tained during ventilation with COMBIBAG:
Inspiratory Oxygen concentration
The oxygen concentration achievable during ventila-
tion depends on the oxygen flow set, the minute vol-
ume and the respiratory frequency. The follwing
oxygen concentrations are achieved, depending
upon the type of oxygen supply (direct supply or ox-
ygen supply with reservoir):
