within one minute after nebulization or suction,
within one minute after last PV loop test.
• The PV tool function is not recommended when
there is great leakage or when the patient has
spontaneous breathing. The relevant characteristic
points the PV tool function provides are only for
your reference.
• If no operation is performed on PV tool screen
within three minutes, the measurement screen exits
automatically.
The PV tool is the method that records a quasi-static
pressure/volume curve showing both the inflation and
the deflation curve to determine the optimal PEEP. The
doctor is able to determine the optimal PEEP for the
patient with the help of this function.
To perform the PV tool as follow:
1. Select the [
Function
] ->[
PV Tool
].
2. Setup the below parameters for PV tool.
P-start
: starting pressure of the static P-V loop.
P-top
: maximum pressure of the static P-V loop can
reach.
End PEEP
: ending pressure of the static P-V loop.
T-pause
: pause time when the static P-V loop reach
the maximum pressure.
Ramp Speed : the speed of the starting pressure
rising to maximum pressure during the static P-V
loop.
The system acquires T-total parameter value based
on the calculation formula and displays it on the
window.
3. Press the [
Start]
key to start PV tool measurement.
Press the [
Stop
] key during measurement, the
system aborts measurement immediately.
4. After the measurement is completed, you can set
the desired positions of [
Cursor 1
