Pulse Oximetry
4 Jun 2021 to 30 Jun 2021

Pulse oximeter measures the oxygen levels in your blood and it hits the trend during this pandemic season.  It is used to monitor individuals with medical conditions that can affect blood oxygen levels such as chronic obstructive pulmonary disease (COPD), asthma, pneumonia, lung cancer, anaemia, heart attack or heart failure, congenital heart defects etc.

What Do You Need to Know About Pulse Oximeter?

  1. While pulse oximeters used at home can detect low blood oxygen (hypoxia) associated with acute COVID-19not all changes in pulse oximetry are related to COVID-19.  Changes might be related to a non-COVID pulmonary problem such as asthma or unrelated pneumonia.
  2. Shortness of breath and low oxygen levels are just two possible symptoms of COVID-19.  It is important to know other possible COVID-19 symptoms such as cough, fever, chills, repeated shaking with chills, muscle pain, headache, sore throat, and loss of taste or smell. These can appear between 2 to 14 days after exposure to the virus. 
  3. Know your baseline level and look out for changes in reading.  If there is a drop, seek a doctor’s advice on what’s causing those changes.   
  4. Depending on the model of the oximeter, the level of oxygen saturation between 95% and 97% is considered normal.  Low blood oxygen (hypoxia) can be defined as a measured oxygen saturation below 94% in the absence of chronic lung disease.  Anything below that would be a reason to call a doctor, and anything under 90% would be a reason to go to the emergency room.
  5. If you have an existing medical condition that may affect blood oxygen levels, seek a doctor’s advice before purchasing. Examples of such conditions are chronic obstructive pulmonary disease, asthma, pneumonia, lung cancer, anaemia, heart failure, congenital heart defects etc.
