SPN-CPAP/PS

Spontaneous-Continuous Positive Airway Pres-
sure/Pressure Support
Spontaneous breathing with continuous positive
pressure level with or without pressure support
Paw
Flow
When the pressure support is not switched on, the
patient's spontaneous breathing is merely support-
ed by an increased PEEP.
During spontaneous breathing on PEEP level, the
patient can be supported with PS. Every inspiratory
effort by the patient on PEEP level that meets the
trigger criteria triggers a pressure-supported
breath. The time, number, and duration of pres-
sure-supported breaths is determined by the pa-
tient's spontaneous breathing.
As in all pressure-controlled ventilation modes, the
tidal volume supplied depends on the difference in
pressure "Psupp – PEEP", the lung mechanics (re-
sistance and compliance) and the patient's respira-
tory drive. The pressure rise from the lower pres-
sure level PEEP to the upper pressure level Psupp
is determined by the Slope or Insp. flow setting.
The start setting can be configured on the page

The pressure support is terminated as soon as the
inspiratory flow falls below 15 % of the maximum
inspiratory flow.

The pressure support is also terminated as soon as
the duration of the support has reached the maxi-
mum inspiratory time. For intubated patients, the
maximum inspiratory time in the Ped. pat. patient
category is limited to 1.5 seconds. For the Neo. pa-
tient category, the maximum inspiratory time can be
set with Timax to a maximum of 1.5 seconds.
