2. Description of the Ventilation Modes
The ventilator has the ability to be used as either a pressure controlled, volume targeted
ventilator, as a pressure limited, time cycled ventilator, and the SLE5000 as a high frequency
oscillation ventilator.
2.1 CPAP
Continuous Positive Airway Pressure
The ventilator generates a continuous positive airway pressure at a level set by the User.
The apnoea alarm will sound if the patient has not made any breath attempts within the set
apnoea period.
User sets the following:-
•CPAP
• Apnoea time
• Manual Breath parameters (Ti and PIP)
•Fi0
2
• Flow breath detection threshold (Set Trigger) - The patient effort required to satisfy
the apnoea alarm.
• High and low pressure alarm thresholds
• Tidal volume, high and low alarm thresholds
• Minute volume, high and low alarm thresholds
2.1.1 CPAP with Apnoea Backup
This is as for basic CPAP mode but if the patient does not make a breath attempt within the
Apnoea time then a pressure limited, time cycled backup breath is provided.
The User turns ON the backup breaths function.
2.1.2 CPAP with TTV (Targeted Tidal Volume) for Back Up Breaths.
This is as for basic CPAP with or without Apnoea Support, where the inspiratory phase shall
be terminated if the set volume has been delivered by the back up breath.
The User sets the following:-
• Enables Targeted Tidal Volume (Tidal Vol) and selects volume to be delivered
•Max PIP
•Max Ti
