At high attitudes, hypoxia-induced erythropoietic drive results in erythrocytosis and an increase in hemoglobin concentration and hematocrit. Hence people with SCD should be careful and report abnormalities to the doctor immediately.
High hemoglobin level is most often caused by low oxygen levels in the blood (hypoxia), present over a long period of time. Common reasons includes bone marrow disease that causes abnormal increase in red blood cells (polycythemia vera) Congenital heart disease and heavy smoking.
Once you have mastered the belly breath, you can add resistance to your exhalation by pursing your lips and exhaling forcefully, and this is what mountaineers call the Pressure Breath. This is one of the most important breaths for climbing at high altitudes that helps combat the decrease in atmospheric pressure
Yes, oxygen is lower in higher altitudes
At altitude, the reduced oxygen content of the blood induces breathing instability, with periods of deep and rapid breathing alternating with central apnea. This breathing pattern is called high-altitude periodic breathing (PB).
