The Triservice anaesthetic apparatus

Area of Science:

• Anesthesiology
• Medical Devices
• Respiratory Therapy

Background:

• The Triservice anaesthetic apparatus is a portable draw-over anesthetic system.
• It utilizes ambient air as the primary carrier gas and includes modules for ventilation and anesthetic delivery.

Purpose of the Study:

• To comprehensively evaluate the performance and characteristics of the Triservice anaesthetic apparatus.
• To assess the output of anesthetic agents and oxygen under varying environmental and operational conditions.
• To determine the airflow resistance and suitability for field anesthesia.

Main Methods:

• The study involved measuring the output concentrations of halothane and trichloroethylene under different temperatures, gas flow rates, and barometric pressures.
• Oxygen output from the Houtonox regulator was quantified, and its effect on inspired oxygen concentration was determined.
• Airflow resistance of the apparatus was measured, including its performance in extreme cold.

Main Results:

• Anesthetic agent output was characterized across a range of conditions, demonstrating variability with temperature and flow.
• Oxygen supplementation effects were quantified, indicating the apparatus's capacity to enrich inspired oxygen.
• Airflow resistance was measured, with observations on performance under cold conditions.

Conclusions:

• The Triservice anaesthetic apparatus demonstrates functional capabilities for anesthetic delivery in diverse settings.
• Understanding its performance parameters is crucial for safe and effective clinical application.
• The apparatus is suitable for field use, with merits and limitations discussed for optimal deployment.
