What Factors Affect Pulse Oximetry Levels?

The main measurement parameters of the oximeter are pulse rate, blood oxygen saturation, and perfusion index (PI). Oxygen saturation (SpO2 for short) is one of the important basic data in clinical medicine. Blood oxygen saturation refers to the percentage of bound O2 capacity in the total bound O2 capacity in the total blood volume.

Oximeter

The main measurement parameters of the oximeter are pulse rate, blood oxygen saturation, and perfusion index (PI).

The first oximeter was developed by Millikan in the 1940s. It monitors the ratio of oxygen-carrying hemoglobin to oxygen-free hemoglobin in the arteries. A typical oximeter is equipped with two

People with vascular disease (coronary heart disease. Hypertension. Hyperlipidemia. Cerebral thrombosis ...)

Lipid deposits in the vascular cavity and poor blood supply. Difficulties in supplying oxygen. In patients with cardiovascular and cerebrovascular diseases, thick blood, coupled with coronary arteriosclerosis, narrow the vascular cavity, resulting in poor blood supply and difficulty in supplying oxygen. The body is "

A microprocessor, memory (EPROM and RAM), two digital-to-analog converters that control LEDs, a device that filters and amplifies the signal received by the photodiode, and an analog-to-digital converter that digitizes the received signal to the microprocessor . LEDs and photodiodes are placed in small probes that make contact with the patient's fingertips or earlobe. Pulse oximeters also typically include small liquid crystal displays.
