volume.
This parameter is calculated and updated in each breath.

cmH
This parameter measures the pressure applied to airway
during an inspiratory pause. This parameter is calculated
and updated in each breath. If the Pause time is less than
50 milliseconds due to setting the Pause% parameter, this
parameter will not be measured.
plateau
P
b/min/l
Rapid Shallow Breathing Index. This parameter is
calculated in 8 breaths but updated at each breath. This
parameter is calculated in PSV and VSV modes.
RSBI
%
Percent of inspired oxygen
This parameter is updated about every 3 seconds and the
displayed value represents the last 12 seconds.

Airway occlusion pressure
This parameter measures the negative airway pressure
generated during 100 msec of inspiration occlusion. This
parameter is used to determine patient ablity to be released
from mechanical ventilation.
A maneuver has been defined for measurement of this
parameter.

Negative inspiratory force
This parameter measures maximum negative pressure
generated during inspiration occlusion. It also indicates
maximum strength of the inspiratory muscles especially
diaphragm.
A maneuver has been defined for measurement of this
parameter.

J/L
This parameter indicates the work required of the patient
to trigger the ventilator. The Respina P1 ventilator
measures this parameter in all mandatory and supported
breaths triggered by the patient except in APRV
ventilation mode. If the ventilator delivers a breath while it
is not triggered by the patient, WOBimp value will be
displayed zero. This parameter is calculated and updated
in each breath.
