Pulse oximetry at high altitude.
Pulse oximetry is a valuable, noninvasive, diagnostic tool for the evaluation of ill individuals at high altitude and is also being increasingly used to monitor the well-being of individuals traveling on high altitude expeditions. Although the devices are simple to use, data output may be inaccurate or hard to interpret in certain situations, which could lead to inappropriate clinical decisions...
متن کاملOxygen saturation of hemoglobin in healthy children of 2-14 years at high altitude in Nepal.
BACKGROUND Individuals residing at higher altitude may have oxygen saturation of hemoglobin different to those living at lower altitude. OBJECTIVES To find out the baseline value of SpO2 in healthy Nepali children (2-14 years) living permanently at high altitude using pulse oximeter and also to study the relation of SpO2 with age, sex and ethnicity. METHODS A descriptive observational study...
متن کاملPeriodic Breathing and Behavioral Awakenings at High Altitude
Objectives. To study the relationship between nocturnal periodic breathing episodes and behavioral awakenings at high altitude. Methods. Observational study. It is 6-day ascent of 4 healthy subjects from Besisahar (760 meters) to Manang (3540 meters) in Nepal in March 2012. A recording pulse oximeter was worn by each subject to measure their oxygen saturation and the presence of periodic breath...
متن کاملA Three-Wavelength Pulse Oximeter for Carboxyhemoglobin Determination
Pulse oximetry measures the relative concentration of arterial oxygenated hemoglobin and reduced hemoglobin. This paper presents the design of a pulse oximeter, which measures the presence of a third substance, carboxyhemoglobin (HbCO), by unfiltered LEDs at 660 nm, 810 nm, and 940 nm. Background information is given on the theory of pulse oximetry. Theoretical approximations and calculations w...

BACKGROUND The aim of the study was to document link between hyperventilatory capacity and risk for developing acute mountain sickness (AMS). METHODS This study was carried out at Karakorum Mountain ranges (Northern areas of Pakistan) from March till July 2004. 54 healthy male subjects were enrolled in this study. Arterial oxygen saturation (SpO2) of the subjects was measured by the pulse oxi...
