Key result
Pulse rate was significantly associated with the presence of acute mountain sickness (OR 1.4; 95% CI 1.1-1.9; p<0.05), whereas arterial oxygen saturation was not.
Why the study?

Hypothesis-generating for pulse rate over SpO2 in AMS assessment; prospective studies needed before any diagnostic role at altitude.
Cross-Sectional (n=169)
Is pulse oximetry data associated with the diagnosis of acute mountain sickness in individuals at high altitude?
Odds Ratio: 1.4 (95% CI 1.1–1.9)
p-value: p=< 0.05
Pulse rate, but not oxygen saturation, was significantly associated with acute mountain sickness, limiting the utility of pulse oximetry for AMS diagnosis.
O’Connor et al. (2004) conducted a cross-sectional in Acute mountain sickness (n=169). Pulse oximetry (pulse rate and oxygen saturation) was evaluated on Presence of acute mountain sickness (OR 1.4, 95% CI 1.1 to 1.9, p=< 0.05). Pulse rate was significantly associated with the presence of acute mountain sickness (OR 1.4; 95% CI 1.1-1.9; p<0.05), whereas arterial oxygen saturation was not.
