Scuba tanks as a compressed air source in positive-pressure ventilation

Area of Science:

• Medical Engineering
• Healthcare Logistics
• Respiratory Therapy

Background:

• Developing countries face challenges in maintaining consistent medical supply chains, including essential compressed gases.
• A regional hospital in Vanuatu required an economical solution for a regulated compressed gas source to power an anaesthetic ventilator.

Purpose of the Study:

• To describe the adaptation of Scuba cylinders for providing regulated compressed gas for anaesthetic ventilators.
• To present a cost-effective solution for medical gas supply in resource-limited settings.
• To suggest other potential applications of this adapted system in hospitals.

Main Methods:

• Modification of Scuba cylinder output to regulate pressure.
• Utilizing a standard diving compressor for gas supply.
• Testing the adapted system for anaesthetic ventilator use.

Main Results:

• Successful adaptation of Scuba cylinders to provide a regulated source of compressed gas.
• Demonstrated economic viability for hospitals with moderate patient loads.
• Identified potential for broader applications in medical settings.

Conclusions:

• Scuba cylinders can be economically adapted to supply regulated compressed air for anaesthetic ventilators.
• This solution offers a practical approach to medical gas supply challenges in developing regions.
• The system has potential for diverse applications in small to medium-sized hospitals with access to diving compressors.
