ARTIFICIAL AIRWAY MANOMETER/INFLATOR
Definition
A device designed to measure the pressure and instill air into the (low pressure) cuff of an in situ endotracheal or endobronchial tube. The inflator includes a manually-operated rubber bulb for the delivery of ambient air into the cuff, and a pressure gauge or manometer that displays the pressure within the cuff to help prevent the development of excessive pressure which may cause trauma to the trachea. The purpose of the cuff is to provide an adequate seal for positive pressure ventilation and to prevent aspirated secretions from passing into the lungs. This is a reusable device.

Specifications
- Analog system with no dependence on any energy source
- Rubber hand bulb for cuff inflation
- Diameter of the dial = +/- 68 mm
- The dial has two zones of measurement graded in cm H2O with colour coding (green = safe range)
- Pressure release valve on the back for adjustment of the pressure
- Hook on the back to aid storage (optional)
- Luer connection: for connection to the tracheal or laryngeal tube allowing pressure measuring and regulation, either directly or via the connecting tube
- Tubing with Luer connection: +/- 100 cm
- Vacuum valve: for connection to the tracheal tube allowing a complete deflation of the cuff by squeezing the inflation bulb

Mechanical ventilation in intensive care (+ operating room)
Will be mentioned in the protocol “prevention of pneumonia acquired under mechanical ventilation” but simple use with direct reading of the “right” pressure on the manometer screen.
