Operating a hyperbaric chamber requires precision, safety knowledge, and a clear understanding of the equipment. This step-by-step guide is designed for trained technicians and medical professionals to ensure safe and effective treatment delivery. Always remember that this guide is for informational purposes, and you must follow the manufacturer’s specific manual and your facility’s protocols.

Pre-Operation Safety Checks and Patient Preparation

Before initiating any treatment, a thorough safety inspection is paramount. This non-negotiable step prevents accidents and ensures a smooth session.

Comprehensive Chamber Inspection

Visually inspect the chamber’s exterior and interior for any signs of damage, corrosion, or loose components. Check all viewports, seals, and the door gasket for integrity. Verify that all safety valves, pressure gauges, and environmental control systems (like oxygen monitors and communication devices) are calibrated and functional. Ensure the chamber is clean and free of prohibited items.

Patient Assessment and Briefing

Conduct a final patient assessment, confirming there are no contraindications for treatment. Clearly explain the procedure, including what the patient will feel during compression and decompression. Instruct them on how to clear their ears and use the communication system. Have the patient change into 100% cotton gowns to eliminate static electricity risks.

The Step-by-Step Operational Procedure

Following a standardized procedure is critical for safety. For a detailed technical manual, you can refer to this resource on How To Operate A Hyperbaric Chamber.

Chamber Pressurization (Compression)

Secure the chamber door following the locking procedure. Begin compression slowly, typically at a rate of 1-2 psi per minute, while continuously communicating with the patient. Guide them through ear equalization techniques. Monitor the pressure gauge closely until the prescribed treatment depth (e.g., 2.0 ATA) is reached.

Monitoring the Treatment at Depth

Once at treatment depth, maintain a stable pressure. Continuously monitor the patient via audio/visual systems. Watch for signs of barotrauma or oxygen toxicity. Manage the chamber atmosphere, ensuring proper oxygen levels and carbon dioxide scrubbing. Record all vital parameters at regular intervals.

Chamber Depressurization (Decompression)

After the prescribed treatment time, begin a controlled decompression. Follow the exact decompression schedule to avoid decompression sickness. The rate is often slower than compression. Continue patient communication, as they may feel temperature changes or ear discomfort. Once at ambient pressure, perform an unlock sequence and open the door.

Post-Treatment Protocol and Maintenance

The operator’s role continues after the patient exits. Conduct a post-session check on the patient for any adverse effects. Then, ventilate the chamber thoroughly. Wipe down all surfaces according to disinfection protocols. Log the treatment details, including start/end times, pressure, patient response, and any incidents. Schedule regular professional maintenance as per the manufacturer.
