In Pakistan's high mountain regions, pastoralism is still practised with families travelling with livestock to summer pastures between 3000 and 4700 m. There have been no studies on oxygen saturation (SaO2) in children in these remote communities. Given their inaccessibility by metalled roads, pastoralists access primary medical care units by foot, travelling over hazardous terrain.
Previous studies on oxygen saturation in children at altitude were in locations accessible by metalled roads and hence, fully serviced. This study's contribution is measuring SaO2 in children in remote Karakoram and Hindu Kush pastures.
This cross-sectional study recorded SaO2 in five consecutive pastures (3043–3750 m) in Pakistan's Hindu Kush and Karakoram mountains; children at 217 m served as reference. These pastures are accessible …
