The pulse oximeter includes a sensor, as well as a machine that will read and display the O2 saturation in the blood. Most of the machines that are available today also have alarms on them in the event that the saturation is too low. The default setting on the machines is generally 90%. The device has a number of uses and benefits, as it can help to detect hypoxemia, which can affect the elderly and cause them to feel confused. It can also provide a steady and continuous reading while a person is undergoing sedation, it allows for correct use of O2 during procedures to reduce waste, and much more.
The sensor is placed on the body – finger, earlobe, or foot, as mentioned above – and the photoreceptor in it will transmit light in two different wavelengths. This measures the percentage of oxygen saturated hemoglobin in the blood. Most people should have a saturation level of above 95%. If it is not, then it is generally an indication that something is wrong. For example, the patient may be suffering from COPD, another respiratory disease, or something such as cyanotic congenital heart disease.If using a finger probe. Make sure that the hand it resting on the chest at the level of the heart, instead of holding it in the air, which is what many patients tend to do.
A pulse oximeter is a device that measures the oxygen saturation in the body. It is a non-invasive device that is simple and painless to use. Most of the time, those who are thinking about these devices imagine the sensor that’s placed on the finger. While that is one example of a pulse oximeter, there are also devices that can go onto the earlobe, as well as those that will attach to the foot of an infant to record the same results
