Relationship Between Arterial Oxygen Saturation and Hematocrit, and Effect of Slow Deep Breathing on Oxygen Saturation in Himalayan High Altitude Populations
ثبت نشده
چکیده
lIn the cross-sectional study of two populations residing at altitude of 2800 m and 3760 m are compared for the difference in hematocrit. The oxygen carrying capacity of arterial haemoglobin (SaO2) is determined by pulse oximetry. The sample is drawn from the natives of two small villages, Thini at Jomsom (2800 m) and Jharkot (3760 m) in Mustang district of Nepal. The natives at 2800 m are termed as lower high altitude population and local residents at 3760 m are said to be higher altitude population in this study. The sample blood was drawn by venipuncture and packed cell volume was determined by Wintrobe’s method.

Relationship between arterial oxygen saturation and hematocrit, and effect of slow deep breathing on oxygen saturation in Himalayan high altitude populations.
BACKGROUND The oxygen saturation of haemoglobin is reduced in high altitude-living organisms. Increase in the hematocrit is responsible for rise in the hemoglobin concentration so that the oxygen carrying capacity in the hypobaric hypoxic subject is elevated. OBJECTIVES To compare two different high altitude populations, in order to study the relationship between arterial oxygen saturation an...

متن کاملEffects of Slow Deep Breathing at High Altitude on Oxygen Saturation, Pulmonary and Systemic Hemodynamics
Slow deep breathing improves blood oxygenation (Sp(O2)) and affects hemodynamics in hypoxic patients. We investigated the ventilatory and hemodynamic effects of slow deep breathing in normal subjects at high altitude. We collected data in healthy lowlanders staying either at 4559 m for 2-3 days (Study A; N = 39) or at 5400 m for 12-16 days (Study B; N = 28). Study variables, including Sp(O2) an...
متن کاملEffects of high-altitude periodic breathing on sleep and arterial oxyhaemoglobin saturation.
This study aimed to investigate the effect of periodic breathing (PB) at high altitude on sleep structure and arterial oxygen saturation (Sa,O2). Five healthy subjects underwent polysomnographic studies at sea level, and during the first and the fourth week of sojourn at 5,050 m. Their breathing pattern, sleep architecture and Sa,O2 were analysed. PB was detected in the high-altitude studies du...
متن کاملRelationship of Oxygen Saturation Percentage (SaO2) and Arterial Oxygen Pressure (PaO2) with the Outcome of Covid-19 Patients Hospitalized in intensive care Units
Background and Objective: In order to determine the Hypoxemia and prognosis of patients with covid-19 hospitalized in the intensive care unit, reliable oxygen supply indicators are needed. In this situation, the examination of the percentage of arterial oxygen saturation (SaO2) and arterial oxygen pressure (PaO2), as well as their relationship, may be helpful. Materials and Methods: This des...
