Glass medication ampoules are safe for hyperbaric chamber use. Testing showed no ruptures or shattering during rapid compressions, decompressions, drops, or opening under pressure, confirming their usability in hyperbaric emergencies.
Area of Science:
- Hyperbaric medicine
- Medical device safety
Background:
- Institutional policy prohibited glass ampoules in hyperbaric chambers due to rupture fears.
- Limited data exists on the safety of glass ampoules under hyperbaric conditions.
Purpose of the Study:
- To evaluate the safety and usability of glass medication ampoules within a hyperbaric chamber environment.
- To determine if standard glass ampoules can withstand hyperbaric conditions.
Main Methods:
- Glass medication ampoules (1-10 ml) underwent rapid compressions/decompressions to 507 kPa.
- Ampoules were dropped from 30 cm at 507 kPa and opened under pressure.
Main Results:
- No glass ampoules fractured during compression, decompression, or drop tests.
- All ampoules opened successfully at 507 kPa without shattering.
Conclusions:
- Glass medication ampoules demonstrate safety for use in medical hyperbaric chambers.
- Findings support the use of glass ampoules for hyperbaric emergency medications.
