The Importance of Pulse Oximeter to Patients

By on Sep 8, 2017 in Technology Trends |

The use of pulse oximeter is mostly used in the hospital, clinics, hospices and doctor’s clinic. Its purpose is to measure the amount of oxygen that is present in the body. This also helps the health care provider such as the doctor and the nurse to read the result that is produced by the Sensors ds100a and it determines the S02 (level of saturation) which is an important factor especially for patients who are struggling with respiratory disorder such as COPD and other types.

Furthermore, if you happened to have a loved one that is bringing oxygen tank in the home and monitoring of air is a must, this is when pulse oximeters truly comes in handy. It is important to choose the right kind and quality so that you will be guided properly in monitoring your loved one’s health status.

How does it work?

The concentration of the blood is detected through the red light pulse oximeter and this depends as to how much the presence of oxygen according to its location. If the blood is fully oxygenated this is simply absorbed more by the infrared light while on the hand, if there is low oxygenated blood this will absorb more of its red light. To test the levels of oxygen in the blood, the use of a pulse oximeter is using both the red and infrared light. As soon as the pulse oximeter is attached to the site area such as the finger, earlobes and toe which emits different types of light wherein it goes through the appendage and right after captured by a photo detector that is found at the other side. The use of a photo detector is to calculate its ratio between the red and the infrared thus convert it into the S02 level or oxygen saturation level that is present in the blood.

What are the limitations of using pulse oximeter?

Low temperatures of the body can affect the reading of the pulse oximeter as the light passes through the skin and this also obscure the reading of the medical device. So, this means that if there is hypothermia, the blood flow is poor and this could not get a proper reading as well. Furthermore, if the pulse oximeter is exposed to the light this can absolutely diffuse the reading of the red and infrared light. Another factor is that if the condition of the body is shivering and cold, the vibration hinders the reading. Basically, the reading of the pulse oximeter matters most , according to how it is positioned.

Benefits of a pulse oximeter

The use of this type of medical device is indeed beneficial to the part of the health care professional and for families who are using it at home. This aids in the promotion of oxygen therapy especially if the patient is for home bound. The use of the pulse oximeter helps you determine the status of the patient whether he needs O2 therapy, helps determine any unusual readings and further implementation of care is provided immediately.
