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 measure accurately and are used to detect even the slightest of changes in blood oxygenation . Even though these medical facilities have a long history, they were spread widely in the 1890s. This is how they function; the oxygen monitor which has a tiny probe is clipped to a spot with good blood flow. This spot can be a finger or an earlobe.

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.

Oxygenated hemoglobin typically absorbs a greater amount of infrared light while allowing the red light to pass through. On the other hand, the deoxygenated blood absorbs more of red lights and allow more of infrared to pass through. An oxygen monitor can calculate the level of oxygenation present by determining by calculating the amount of light absorbed by the hemoglobin at the two different wavelengths.

If an oxygen monitor detects any change in the level of oxygen of a patient under anesthesia, then it sounds an alarm. This is important because, a heart failure and drain damage can occur if the human body is starved of oxygen in as little time as three minutes. This is why early detection is quite important.

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 different types of oximeters, and they include pediatric which can be wrist, handheld, and finger oxygen monitor. Pediatric oxygen monitors are designed for children producing, and they produce very accurate results. They have features that help in determining the best finger for testing and position. These devices were once too large and expensive for patients to have in their home, but now there are portable and affordable oxygen monitors in the market today.

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 .
