What Researchers Did
Researchers developed and tested a new noninvasive method to monitor blood pressure inside a monoplace hyperbaric chamber using a standard cuff and a Doppler probe.
What They Found
They found that this noninvasive method provided blood pressure readings (mean 112 +/- 8.1 mm Hg) that closely matched those from invasive arterial catheters (mean 114 +/- 7.6 mm Hg). This comparison was based on 92 measurements taken from 8 subjects, leading to the conclusion that the noninvasive method is accurate and suitable for clinical use in monoplace chambers.
Canadian Relevance
No direct Canadian connection identified.
Study Limitations
The study involved a small number of normal subjects and was conducted over three decades ago, which may limit its current applicability.
