POTENTIAL TIDAL VOLUMES
The potential tidal volumes for the corresponding set volumes on the Life2000
®
Ventilator are shown in the
following graph. The graph can be used to obtain approximate values only.
The potential patient volume per breath is a combination of ventilator settings (Volume and I-Time) plus the
amount of room air entrained to the patient interface plus the amount of supplemental oxygen (if any) that is
injected into the patient interface. It is further influenced by the patient’s resistance, compliance and effort. As a
result, the potential patient volume will be higher than the ventilator set volume.
NOTE:
This graph uses a PEEP value of 0 cmH
