“…using a single pulse oximeter (Mini O 2 Saturation Monitor, 4500 Scout, Invivo Research Inc., Orlando, Fla., USA), with the same probe on the index finger of the right hand. This instrument performs very well compared to other pulse oximeters [14] and in relation to simultaneously obtained arterial blood samples has a bias of 0.2% and a precision of 2.05% [15]. Before Sa O 2 was measured subjects remained at rest in a sitting position for 10 min.…”

Background: Arterial hemoglobin oxygen saturation (SaO₂) decreases at an altitude of >1,500 m. There are no reports on normal SaO₂ at altitudes between 0 and 1,500 m. The clinical significance of decreased SaO₂ at such altitudes is unclear. Objective: To test the hypothesis that in healthy volunteers normal SaO₂ at moderate altitude (MA; 725 m) is lower than that at almost sea level (SL; 43 m). Methods: SaO₂ was measured by transcutaneous pulse oximetry in young healthy volunteers at MA and was compared to equivalent measurements at SL. In addition, a 6-min walk test was performed and SaO₂ at the end of the walk was compared between the two locations. Results: 111 males were checked at MA and 101 at SL. At rest, nadir SaO₂ was 95% at MA compared to 97% at SL. Mean SaO₂ at rest was slightly higher at SL (98.53 ± 0.52) compared to MA (98.11 ± 0.8; p < 0.01). In subjects who completed the 6-min walk test, SaO₂ slightly decreased after the test in both locations, by 0.38 ± 0.65% in the SL group and by 0.37 ± 1.12% in the MA group. This difference is not statistically significant by univariate analysis; however, a multiple regression analysis indicated that the drop in SaO₂ was higher at MA than at low altitude. Conclusions: We found a low but significant difference in SaO₂ between near-SL and at an altitude of 725 m. The clinical significance of this difference, in terms of human health, is probably minimal.

“…Measurements at sites other than the finger or ear, such as the forehead and nose, give no improvement in poorly perfused patients (CLAYTON et al, 1991;ROSENBERG and PEDERSEN, 1990). Thus, SpO 2 readings are often unobtainable at just the time when they would be most valuable.…”

“…4,5 In most clinical settings, the pulse oximeter continuously monitors oxygen saturation levels but, in some settings, various factors (e.g., severe hypotension, low perfusion, or shivering due to hypothermia) interfere with accurate measurement. 2 Because these factors disrupt peripheral circulation, finger SpO 2 can be abnormal.…”
