Summary

What Researchers Did

Researchers conducted a double-crossover prospective study to compare the effectiveness of a portable hyperbaric chamber versus a nonrebreather mask for eliminating carboxyhemoglobin in smokers.

What They Found

The modified Gamow bag significantly increased the elimination of carboxyhemoglobin (COHb) compared to a nonrebreather mask (P < .05). The average half-life for COHb elimination using the Gamow bag was 27.5 minutes (n = 10).

Canadian Relevance

This study was not conducted in Canada and does not have a direct Canadian connection.

Study Limitations

A key limitation is the small sample size of healthy smokers and incomplete data for two participants due to IV access failure.
