Saadat Respina P1 User Manual page 83

When apnea backup is on if the patient makes no breath effort once the set apnea time has
passed, backup ventilation will be provided and apnea alarm will be activated. If apnea
backup is off, apnea alarm will be activated and the ventilator will not switch to backup
ventilation mode (in this condition if apnea backup is set on, backup ventilation will be
provided).
Apnea mode is disabled if:
- the patient triggers two consecutive breaths.
- the patient triggers four consecutive breaths within the latest 10 breaths.
- the user changes the ventilation mode (for example an apnea occurs in PSV mode)
- the user selects a ventilation mode except PSV mode.
- the user inactivates the apnea mode.
Other notices
- Ins. Hold, Exp. Hold and Manual maneuvers can be performed in the apnea mode.
- Manual inspiration maneuver will not disable the apnea mode.
- If the apnea backup conditions occurred during one of PSV, VSV or APRV modes,
selecting another mode will result in disabling the apnea backup. If the new mode is
one of the PSV or VSV modes, the apnea alarm will remain active until the patient
triggers the device.
In addition, these two modes are set separately in Apnea Backup window.
When apnea backup is on, the current backup mode is displayed red instead of ventilation
mode.
Note:
- In volume based modes, if the airway pressure exceeds the upper limit of the
pressure alarm – 5 cmH2O, the exhalation valve opens. Also, if the pressure has
exceeded the upper limit of the pressure alarm, the inhalation terminates and the
exhalation begins.
- In pressure based modes during inhalation, if the pressure exceeds the set pressure
+ 4 cmH2O, the exhalation valve opens to maintain pressure. But if the pressure
has exceeded the upper limit of the pressure alarm, the inhalation terminates and
the exhalation begins.
- In volume based modes, the exhalation valve opening to maintain pressure may
cause that the set volume does not deliver to the patient.
