All of us have our pulses running, and it indicates whether we are alive or dead. The pulse rate is a direct indication that our heart is pumping. Many times when we visit a doctor we see them checking our pulses, but have you ever thought, what does the doctor presumes, reading our pulses?

Well, out pulses rate is the estimation of the number of times our heart contracts per minute. Under normal circumstances, an adult’s heart reads a beating of 60 to 100 times a minute, which is a clear indication that the body is functioning correctly.

But what if it is beating slower or higher than normal?

Medics take the help of a pulse oximeter. It helps in measuring the oxygen saturation in the blood. It is perhaps the easiest and effective way to measure the level of oxygen in the blood. This device quickly reads and provides the statistics and as well informed of the current heart rate. The device is a great way to give a quick synopsis of the heart rate, whether your heart pumps higher than normal after a sports activity or tells about slower heart rates that might indicate something wrong.

People with health conditions of asthma, congestive heart diseases, COPD and other similar conditions. Pulse oximetry is the technology that is used to measure the oxygen levels in the blood and the heart rate.

Why one do really needs pulse oximetry using pulse oximeters?

In simple words, the technology is used to see that whether there is enough oxygen in the blood or not. There are numerous reasons to know the readings like:

  • To understand and know how medicines of lungs given to patients are doing.
  • During or after a surgery or even any procedure where there is a need of sedation.
  • To check whether a person will be able to handle heightened activity levels.
  • To check if some needs external sources like ventilators to breadth.
  • In cases or sleep apnea, where at times breathing stops completely during sleep.

Apart from the above mentioned medical purposes, the device is also used to check conditions of a person that effects his or her blood oxygen levels such as:

  • Asthma
  • Pneumonia
  • Heart Attacks
  • Heart Failure
  • Anaemia
  • Cancer of the Lungs
  • COPD (Chronic Obstructive Pulmonary Disease)

Types of Pulse Oximeters

There are four types of pulse oximeters that has been devised to cater to as per needs. They are:

  • The Fingertip Type: clipped to the patient’s finger and has a monitor and a tiny computer.
  • The Wrist Type: is just like a band wrapped around the wrist with a sensor that is slid on to a finger.
  • The Hand Held Type: the one used in hospitals, is similar to the fingertip type but is more advanced and has added features. It is clipped on the fingertip and earlobes too.

The Tabletop Ones: unlike other types, it is non-portable and is used for continuous readings. Can also be clubbed with other medical tools and has the maximum features.
