Explanation of P0.1 Measurement Function Conditions
After the P0.1 Measurement Function is activated the following
condition occurs:
• Ventilation continues according to user settings but a 3-minute
timing window opens within which the user may touch START
P0.1. The function times out if the measurement is not started
within this time frame.
After START P0.1 is touched the following conditions occur:
• Ventilation continues per user settings.
• Backup ventilation is disabled for one minute.
• When the e360 detects a patient trigger, it imposes a 100
millisecond delay before delivering inspiratory flow to
the patient.
• Normal operation resumes after the first patient trigger
or after one minute if no trigger is detected.

Negative Inspiratory Force (NIF) Maneuver

(also referred to as Maximum Inspiratory Pressure (MIP) or PIMAX)
While ventilating, the Negative Inspiratory Force (NIF) Maneuver is
available for measuring airway pressure during a maximum inspiratory
5-1
effort. This measurement is used to assess the patient's inspiratory
muscle strength.
This function is enabled via the NIF button on the Technical Screen.
