3.2 Jet Mode
The Jet Mode, can be postoperatively used to liberate the patient from mechanical ventilation
and to stimulate spontaneous breathing. The maximum driving pressure is limited to 1.5 Bar.
Jet mode shall only be used with Tritube, not with conventional endotracheal tubes, with the
cuff of Tritube fully deflated to enable expiratory gases to freely egress.
Warning: The cuff must be deflated by hand before Jet Mode can be started.
Risk on barotrauma.
Warning: The cuff must be checked for accumulated debris before deflation.
Risk on infection.
Warning: Do not use the Jet Mode in combination with the Evone Conventional
Tube Adapter. Risk of barotrauma.
Warning: Do not use mode for longer than 30 minutes on a single patient.
Risk of dehydration.
The Jet cycle is governed by 3 operator settings being:
• Frequency
• Inspiration Percentage
• Driving Pressure
