Pulse Oximeter

Every human body needs oxygen in order to survive. This means that every human organ and system needs oxygen without which, cells may begin to fail and thus will ultimately die. This might lead to organ failure. That is why oxygen saturation levels should be maintained. For that, it is important to know the individual oxygen level. A Pulse Oximeter is a device that was developed for the measurement of blood oxygen saturation level and pulse rate. This tool is used in wide industries like hospitals, operating rooms, medical clinics and even more.

When Pulse Oximeter Is Used?

As referred earlier, the purpose of this equipment is to check the oxygen pumping through an individual body in order to know how well it has been pumping. It is medically used on patients with the following any type of medical conditions,


  • Asthma
  • Emphysema,
  • Chronic obstructive pulmonary disease (COPD),
  • Chronic obstructive airway diseases (COAD),
  • Pneumonia
  • Lung cancer
  • Anemia
  • Heart attack
  • And other respiratory conditions

Generally, the certified physician will perform its process, in case people are not feeling well. To improve the people’s stamina, the physician will sometimes recommend a patient to exercise regularly. This will help in increasing the shortness of breath however they should regularly monitor the oxygen level with pulse oximeter so that, they can adjust the speed when the oxygen level decreases.

How Does Finger Pulse Oximeter Work?

At first, the pulse oximeters will be attached to the devices, which help to measure the oxygen level. This device, in order to read the blood flow of an individual, then it gets attached to the patient’s finger, or wrist or foot or any other part.  Finger Pulse Oximeter indicates its working process by glowing light on the surface area of the part where the device is attached. Then, the light glows through to a detector, which is placed on the other side of the skin.

For instance, in case, if the pulse oximeter is attached to the patient’s finger, one side of the device will shine the light whereas the other side will detect it.

Benefits of Pulse Oximeter

  • Helps to monitor oxygen saturation level
  • Gives alert to low oxygen level
  • Offer peace of mind
  • Assures the need for oxygen
  • Indicates danger side effects

Nowadays, many medical clinics and hospitals are available with such device, so if you are experiencing any above-mentioned medical conditions, seek experts and prevent illness at the earlier stage.
