Information On CMS Pulse Oximeters

By Leticia Jensen


Pulse oximetry basically involves monitoring blood oxygenation. Oxygen saturation should always be above 95 percent. Cms pulse oximeters are non-invasive medical devices that are used by health care workers to monitor the level of oxygen in patients blood to ensure it does not drop below levels that are safe. These devices are important in any areas where the level of oxygen in the patient body is important to monitor. So they are used in emergency and intensive care, operations, and treatment and recovery in hospital wards.

These devices are made in such a way that they are able to make slight detections on deficiency of oxygen flow in the body. The initial machine was made 1890s and from then it is still being used. The operation of this machine is as follows; the device has a tiny probe that is attached to the patient body, and specifically in areas that they have enough blood flow. The body parts which it is commonly attached to are either the earlobe or finger.

This monitor is then attached to a separate computerized unit whose work is majorly to display the readings. Inside the probe there is a light emitter that sends out two streams of light. One is red and the other infrared. These steams of light emitted are received and measured by a photo detector, which is located opposite the emitter.

Typically, the oxygenated hemoglobin takes in a larger amount of the infrared light . The red light is allowed to pass through. It is the vice versa when it comes to the deoxygenated blood. It actually absorbs more red lights and allows the infrared light to pass through. The level of oxygenation in the patient blood is calculated by the oxygen monitor. This is determined by measuring the amount of light which is absorbed by the blood hemoglobin at both wavelengths.

When the oxygen monitoring device detects any oxygenation change of a patient suffering from anesthesia, it is necessary to raise an alarm. This is because it might cause a heart failure or brain damage if the body lacks sufficient supply of oxygen for even three minutes. Therefore early diagnosis is very important for one health.

As mentioned early, a healthy body should never fall below 95 percent of O2 saturation. The good thing with these monitoring devices is that they are able to detect a change as small as one percent. Before oxygen monitors were discovered, healthcare practitioners would only manage to detect oxygen starvation when the patient is already at very critical conditions.

There are various types of oximeters. They include pediatric which can be a wrist, handheld or finger oxygen monitor. These monitors are specifically designed for children and they produce results that are so accurate. They are made of features that help in sensing the best finger for testing and its right position. Unlike when these devices were too large and quite expensive for patients to own them, nowadays they are portable, affordable and available in the market.

There are many versions of cms oxygen monitors available today but the most effective ones are the finger models. They are also very affordable. They are sold as from 30 dollars, including delivery. These devices are used for treating pneumonia as well as neonatal blindness by anesthesiologists .
