Tidal Volume for values lower than 20ml is set adjusting pressure, monitoring the tidal volume in the display of the ventilator. This volume is
(1)
the volume delivered to the ventilator outlet, and the user should check the absence of leaks".
(2)
In CPAP/PSV mode adjusted without pressure support and without backup respiratory rate will be zero.
(3)
Inspiratory flow automatically obtained adjusting Volume, Rate, Ratio I:E / Inspiratory time and Pause
Example (1):
Inspiratory Flow = ----------------------------------------- = 6.00 L/min
Example (2):
Inspiratory Flow = -------------------------------------------------- = 102.86 L/min
Example (3):
Volume = 2200 mL; Rate = 12 min-1; Ratio 1:3; Pause = 40%
Inspiratory Flow = ------------------------------------------------- = 176.00 L/min
In CPAP/PSV mode, if pressure support (∆PS = zero or Pressure and Flow Sensitivity = zero) is disabled, CPAP parameter will
(4)
be adjusted.
In VCV, adjustment allowed is in the range between 1:4 and 4:1
(5)
Backup options for CPAP/PSV mode; for DUALPAP mode, backup options are: PLV for neonatal, PCV for adult or OFF. Setting OFF, mode
(6)
will not enter in backup when time for apnea alarm is reached.
For modes with controlled volume, maximum compensation is 100% flow adjusted automatically
(7)
Depending on the type of patient set during startup, the ventilator will be set to operate according to the following table:
