Description of ventilation modes
Continuous Positive Airway Pressure
(CPAP)
The device maintains airway pressure at the
PEEP/CPAP level. The patient can always breathe
spontaneously. The flow setting should be
significantly higher than is required for the patient
to breath spontaneously in order to prevent
fluctuations in airway pressure and increased work
of breathing.
Intermittent Positive Pressure
Ventilation / Intermittent Mandatory
Ventilation (IPPV/IMV)
Mandatory ventilation with continuous flow without
taking spontaneous breathing into account.
Mechanical breaths are applied at a rate between
T
I and TE.
No distinction is made between IPPV and IMV
because the wide setting range for TE (up to 30 s)
covers the IMV frequency range.
The device maintains airway pressure at the
PEEP/CPAP level between mechanical breaths.
The patient can always breathe spontaneously.
The following settings determine the parameters of
the mechanical breath:
– Flow determines the ramp
– Inspiratory time T
I determines the duration
– Inspiratory pressure Pinsp limits the pressure
