Abstract

The invention discloses an oxyhemoglobin saturation measuring method. The oxyhemoglobin saturation measuring method comprises sending first measuring light, second measuring light and reference light to body surface skin of a measured object and receiving reflected light of the first measuring light, the second measuring light and the reference light; obtaining a first difference value and a second difference value, wherein the first difference value is the difference of rates of light intensity change of the first reflected light and the reference reflected light and the second difference value is the difference of rates of light intensity change of the reference reflected light and the second reflected light; obtaining a ratio x of the first difference value and the second difference value through calculation and calculating the oxyhemoglobin saturation y according to the ratio x. Correspondingly, the invention also provides an oxyhemoglobin saturation measuring portable device. According to the oxyhemoglobin saturation measuring method and portable device, accurate measurement of the oxyhemoglobin saturation can be achieved in real time.

Description

technical field [0001] The invention belongs to the field of physiological parameter measurement, and in particular relates to a method for measuring blood oxygen saturation and a portable device. Background technique [0002] Oxygen is an important element to maintain normal physiological activities of the human body. Oxygen in the air enters the blood after being exchanged through the lungs of the human body, and is combined with hemoglobin to be transported to the whole body. Hemoglobin consists of four chains, two alpha chains and two beta chains, each chain has a ring of heme containing an iron atom. Oxygen binds to iron atoms and is transported by the blood. Each gram of hemoglobin can bind 1.34ml of oxygen, which is 70 times the amount of dissolved oxygen in plasma. [0003] Oxyhemoglobin (HbO 2 ) and reduced hemoglobin-based oxygen saturation (SO 2 ) characterizes the state of the human oxygen cycle, and is an important parameter for judging the human respiratory...
