What Researchers Did
Researchers tested 12 Vibrant Soundbridge® active middle-ear amplifiers in a hyperbaric chamber to determine their resistance to high-pressure conditions.
What They Found
All 12 Vibrant Soundbridge® devices maintained normal function after single hyperbaric exposures up to 608 kPa for 78 minutes.
Visual inspections and laboratory function tests showed no structural damage, implosion, or loss of performance.
What This Means for Canadian Patients
Canadian patients with a Vibrant Soundbridge® active middle-ear amplifier may be able to safely undergo hyperbaric oxygen therapy or participate in diving activities.
This finding could expand treatment options and improve quality of life for individuals needing such therapies or wishing to engage in water sports.
Canadian Relevance
This study has no direct Canadian connection as it was conducted in Germany and involved devices from a German manufacturer.
Study Limitations
The study's main limitation is that it only tested one specific type of active middle-ear amplifier and involved only a single hyperbaric exposure for each device.
