Describe in brief the principle of Jet Ventilation. What are its applications in the management of ENT and Head & Neck diseases? Discuss in brief the advantages, limitations and complications of Jet ventilation . (2+2+2+2+2) Dec 2015
Jet ventilation is used as a lifesaving maneuver in CICV “cannot intubate – cannot ventilate” situation for oxygenation to avoid a severe desaturation of the patient.
Jet ventilation is of two types, i,e high or low frequency. HFJV is a versatile, safe and effective technique with growing indications for elective and emergency use.
The general principles of both methods are the same: jet-streams originating from high-pressure sources are cut by pneumatic or electronically controlled flow interruption devices.
Definition of Jet Ventilation​1​
Douglas Sanders described a technique that allowed uninterrupted patient
ventilation concurrent with unhindered surgical access through an open, rigid bronchoscope.​2​
HFJV is characterised by delivery of small tidal volumes (1-3mls/kg) from a high pressure jet at supraphysiological frequencies (1-10Hz) followed by passive expiration. ​1​
Indications of Jet Ventilation
HFJV is indicated when it offers advantages over conventional ventilation. These indications fall into two main categories; to facilitate surgical access and to optimise pulmonary function.
