Significance of Pulse Oximeter

Generally, pulse oximeter is used to check the oxygen level in the blood of people with some chronic condition or major health issue like COPD, asthma, pneumonia, heart attack etc. This helps in knowing the efficiency with which oxygen is being pumped by their hearts. This is important as these patients experience low level of oxygen in the blood and that can be life-threatening.



Pulse oximeter is used to know if a patient needs help breathing and how effectively a lung medication is working. It also evaluates the effectiveness of a ventilator and supplemental oxygen therapy.

Link between pulse oximeter and coronavirus

As a pulse oximeter checks the amount of oxygen in your blood, it can warn you about the falling oxygen level and a potential shortness of breath, which is a major symptom of coronavirus. It doesn’t let you wait for the prominent symptoms to fully come up and create an emergency situation.

So, we can say that it is beneficial during this time of crisis for warning us about our deteriorating health conditions. And, if falling oxygen level is followed by any mild COVID-19 symptoms including fever, body ache etc., you can immediately go for coronavirus testing.

A pulse oximeter is especially helpful for older people or those with underlying condition as they are more vulnerable to coronavirus due to their weak immune function.
