WebCarbon dioxide molecules are transported in the blood from body tissues to the lungs by one of three methods: dissolution directly into the blood, binding to hemoglobin, or carried as a bicarbonate ion. Several properties of carbon dioxide in the blood affect its transport. First, carbon dioxide is more soluble in blood than oxygen.

WebBackground: Compared to measurements at sea level, measurement of oxygen saturation by pulse oximetry (SpO 2) at altitude differs fundamentally because of the cyclical course of SpO 2, caused by periodic breathing.Therefore, the determination of a representative SpO 2 value is difficult.
