For Oxygen saturation on Langtang Valley, expected values change with altitude and acclimatization; a clinician or trained expedition team should interpret the trend and symptoms. Can a pulse oximeter diagnose HAPE or HACE?+ No. It can support monitoring but cannot diagnose or rule out serious altitude illness. What is a typical SpO2 baseline for healthy trekkers at Kyanjin Gompa (3,870 m)?+ Resting saturation levels between 80% and 88% are standard; drops below 70% accompanied by lethargy warrant medical descent. How can cold fingers distort oximeter readings in Langtang?+ Vasoconstriction from freezing morning temperatures impedes capillary blood flow, often showing false low readings until fingers are warmed. ## Sources & methodology Use the dated sources below for the claims they support.
