Valid Article
ANAESTHESIA VENTILATOR (Glostavent Helix)
Definition
A mains electricity (AC-powered) stand-alone, automatic cycling device used to assist and control alveolar ventilation during general anaesthesia, and is compatible with inhaled anaesthetic agents. It has fewer functions and is less complex to operate than an intensive care ventilator, but adequately meets the patient's ventilation needs for oxygen (O2) and carbon dioxide (CO2) exchange to maintain normal blood gas concentrations. The device provides a mechanical means to deliver the breathing gas to the patient > 10 kg in a controlled pattern, and is equipped with alarms to warn of changes in respiration or the onset of unsafe operating conditions.
Specifications
The ventilator is a time-cycled, volume limited, pressure generator. It consists of a set of gas driven bellows. The drive gas is oxygen supplied either by the concentrator or, in the event of an electricity failure, from the reserve oxygen cylinder or external oxygen source.
After it has driven the ventilator it is collected and returned to the breathing circuit to supplement the inspired oxygen concentration, always providing the patient with a minimum of 35% oxygen.
The UPS provides a reserve supply of electricity for approximately 30 minutes. It also functions as a voltage and frequency regulator.
The vaporiser can be used with isoflurane (replaces halothane).
Composed by four principal components:
- a versatile breathing system
- a pneumatically driven ventilator
- an oxygen concentrator
- an uninterruptible power supply for voltage stabilisation and battery backup
Packed in wooden case

Instructions for use
Maintenance
Between patients and after every operating day clean and disinfect the equipment and sterilize patient circuits (see Protocol I: User Maintenance).
The manufacturer (Diamedica) issued early 2019 a field safety notice after an incident involving the failure of a battery in a Glostavent Helix anaesthesia machine. They advise a precautionary inspection of the equipment in line with a supplied checklist.
