How to use pulse Oximeters - Firstmed
Posted by : Firstmed    29-10-2021

Pulse Oximeter is a non-invasive and painless technique for determining your oxygen saturation level or the amount of oxygen in your blood. It can detect even small variations in the efficiency with which oxygen is transported to the extremities furthest from the heart, such as the legs and arms.

A pulse Oximeters is a little clip-like device worn on the toes or earlobe. It's normally worn on one's finger and is commonly used in emergency rooms and hospitals. Some doctors, pulmonologists, may use it in the office.

Uses and purposes

Pulse Oximeters are devices that measure how efficiently your heart pumps oxygen throughout your body.

It can be used to monitor the health of persons in hospitals who are suffering from any illness that affects blood oxygen levels. These are some of the circumstances.

• Chronic obstructive pulmonary disease (COPD) 

• Asthma

• Pneumonia

• Carcinoma of the lungs

• Anemia

• A heart attack

• Congenital heart defects

Pulse Oximeters is used in a variety of situations, including the following:

  • to see how effective a new lung drug is
  • to determine if someone requires assistance with breathing
  • to determine the efficiency of a ventilator
  • to keep an eye on oxygen levels during or after sedation-induced surgery

How does it work?

A little clamp-like device is put on a finger, earlobe, or toe during a pulse Oximeters reading. The amount of oxygen in the finger is measured by little beams of light passing through the blood. It accomplishes so by detecting variations in light absorption in oxygenated and deoxygenated blood. This is a simple procedure.

As a result, pulse Oximeters can tell you your oxygen saturation levels as well as your heart rate.

  • to see how effective supplemental oxygen therapy is, especially if it's a new treatment
  • to determine a person's tolerance for increasing physical activity
  • During a sleep study, to see if someone stops breathing for a brief period of time while sleeping, as in sleep apnea.

How Oximeters pulse is helping people in covid?

If a person has a mild case of COVID-19 and is self-treating at home, Oximeters can be useful for monitoring oxygen levels and detecting low oxygen levels early. People with pre-existing lung disease, heart disease, and/or obesity, as well as active smokers, are theoretically more at risk for oxygen problems.

Furthermore, because "happy hypoxia" can occur in otherwise asymptomatic individuals, pulse Oximeters can help ensure that this clinically silent early warning sign is not disregarded.

If you have tested positive for COVID-19 and are concerned about any developing symptoms, contact your doctor right once.

 Aside from the objective pulse Oximeters measurements, I tell my patients that if they have any hard breathing, acute chest pain, uncontrollable coughing, or dark lips or fingers, they should go to the emergency room.

Pulse oximetry readings

In most circumstances, pulse oximetry is a fairly accurate test. This is especially true when working with high-tech equipment present in most medical offices and hospitals. It consistently generates findings that are within 2% of what they genuinely are.

Your true oxygen saturation level could be anything between 80 and 84 percent if your result was 82 percent. However, the quality of the waveform and the individual's judgment must be considered.
