3.5.2 Live Monitoring Parameters
The following Live Monitoring Parameters are displayed at the section 2 of the
screen:
Paw
AV
(cm H
2
O):
Paw AV is the average patient airway pressure measured during the last 60
seconds. This measurement is monitored by the ventilator at all times and
modes. The number on the display will be updated every 15 seconds.
Mve
(L):
Minute volume is the total exhaled volume for the last 60 seconds as
calculated using the last 8 breaths. The Mve will constantly change as the value
is recalculated and displayed at the end of exhalation phase. When unit is first
turned on or resumed after pause or on selecting a new mode, the Mve
calculation will be based on first then second then third and so on until the 8
th
exhaled tidal volume when the above logic will be followed.
Rate (BPM):
Rate (BPM) is the rate at which breaths are delivered in one minute. It is the
monitored breath rate calculated by measuring the time interval (T
b
in
seconds) between 2 breaths. Rate (BPM) = 60 / T
b
. The number is updated
after each breath. This number will be displayed for both mandatory and
spontaneous breathing phases.
Vte
(ml):
Tidal volume is the volume exhaled from the patient in mandatory or
spontaneous breaths. Vte is calculated by the measurement of the entire
expired flow displayed as a volume. Vte display will be updated at the
beginning of the next inspiratory phase (The end of exhalation phase).
Paw
Peak
(cm H
2
O):
Peak air way pressure is the maximum pressure measured during the
inspiratory phase. The displayed number on the screen represents the
maximum pressure during mandatory inspiratory phase of SIMV, CPR modes
as well as spontaneous inspiratory phase of CPAP mode. This number will be
updated at the end of each inspiratory phase.
Note
Mve, Rate and Paw
AV
are not active during CPR mode and displayed with “--“
