How Does Pulse Oximeter Work

In this news article we will talk about how pulse oximeter works as personal care so that you know that benefits of using it. The pulse oximeter, which is used to evaluate the oxygen in the blood of patients in a variety of clinical settings, has become an increasingly common piece of monitoring equipment. It provides continuous monitoring, noninvasive oxygen saturation of hemoglobin in arterial blood. Their results are updated with each pulse wave.

The OLED pulse oximeter monitor does not provide information about the concentration of hemoglobin, the heartbeat, the efficiency of oxygen delivery to tissues, oxygen consumption, adequacy of oxygenation or adequacy of ventilation. They do, however, offer an opportunity for saturation levels are immediately seen as a warning to physicians to help prevent the consequences of desaturation and hypoxemia detect before it causes cyanosis.

It has been suggested that the increased use of pulse oximeters in general wards could be to become as common as the thermometer. However, it has limited education and limited device performance understanding of how it works and what factors can affect readings.

Oxygen from the air you breathe using lungs. Oxygen passes into the blood, where most of the oxygen binds to hemoglobin (a protein located inside the blood cell) for transport in the bloodstream. The oxygenated blood circulates through the tissues.

The pulse oximeter technology uses the light absorption characteristics of hemoglobin and the pulsatile nature of blood flow in the arteries to assist in determining the oxygenation status in the body. First, there is a color difference between the arterial hemoglobin saturated with oxygen, which is bright red, and venous hemoglobin oxygen, which is darker.

Second, with each pulse or heartbeat there is a slight increase in the volume of blood flowing through the arteries. Due to increased blood volume, however small, there is an associated increase in hemoglobin rich in oxygen. This represents the maximum amount of oxygen-rich hemoglobin pulsating through the blood vessels.
