What Researchers Did
Researchers used electron microscopy to examine human tissue samples obtained from individuals who died from decompression sickness after hyperbaric air therapy.
What They Found
They identified intra- and extracellular gas bubbles of varying sizes throughout the entire body of subjects with fatal decompression sickness. Each bubble was covered by a non-homogeneous osmiophilic coat, measuring from 30 to 560 Angstrom-units in thickness, which the authors suggest prevents nitrogen elimination.
What This Means for Canadian Patients
This study provides fundamental insights into the microscopic changes occurring in fatal decompression sickness, specifically the nature of gas bubbles in tissues. Understanding the physical characteristics of these bubbles and their surface coats could potentially inform future strategies for preventing or treating severe decompression illness.
Canadian Relevance
This study has no direct Canadian connection mentioned in the provided metadata.
Study Limitations
The study's findings are based on post-mortem tissue analysis from fatal cases, which may not fully represent the processes in non-fatal decompression sickness.
