the patient's respiratory drive. It is an index for the inspiration breathing
effort by the patient against a closed system in the first 100 ms.
Fig. 22: Maneuver P0.1
A PEEP of minimum 4 mbar must be present for measurement of the
P0.1 value. Then select the »Start« field. At the patient's next inspiration,
EVE now automatically detects the spontaneous breathing effort by the
patient, closes the system and measures the P0.1 value. When the
measurement is complete, the determined value appears in the display.
The three most recent measured values are saved and displayed for
reference purposes.
