Expiratory time constant
This parameter indicates time constant of the lung
deflation and is measured during 100 to 500 msec of the
expiration. This parameter is calculated and updated in
each breath.

The output gas temperature of the device
The output gas temperature from the device, which is
calculated by air flow and oxygen sensors. The
temperature of each gas,is affected by the calculation of
the output gas temperature, if its flow is higher than 0.5
liters per minute.

Note:
All flow and volume measurements, curves and loops are displayed in BTPS units.

Respiratory Curves
Respiratory curves are displayed in the middle of the screen. These curves from top to bottom
are: Pressure-time, Flow-time, Volume-time
In the curve inspiration phase of mandatory breaths is displayed in red and the exhalation
phase is displayed in green. Inspiration phase of spontaneous breaths is displayed in yellow
and the exhalation phase is displayed in green.
The Respina P1 ventilator displays two respiratory loops at the right side of the screen. These
loops are: Flow-Volume, Pressure-Volume
Changing scale of respiratory curves
There are some scales for each curve by default. The user can select desired scale by touching
axes of the curve.
Available scales for below parameters are:
Time: (0, 12) (0, 30) (0, 120)
Pressure: (-5, 30) (-10, 50) (-20, 80) (-60, 150)
Flow: (-20, 15) (-80, 40) (-100, 80) (-200, 200)
Volume: (0, 50) (0, 200) (0, 900) (0, 1200)
