Happy Hypoxia: Risks, Symptoms, and Safety Measures

What is Happy Hypoxia?

Hypoxemia is defined as “a decrease in the partial pressure of oxygen in the blood.” As blood oxygen levels begin to reduce, a person may experience shortness of breath, also called dyspnea. If blood oxygen levels continue to fall, the organs may shut down, and the issue becomes life threatening.

The ongoing COVID-19 pandemic holds many mysteries. Among those mysteries is the frequency of silent hypoxemia, or happy hypoxia, as it has been dubbed in the media.

COVID-19 is primarily a respiratory illness, and a severe case can reduce the amount of oxygen that the lungs can absorb. Blood oxygen levels have been found to be very low in some COVID-19 patients.

Therefore, it is imperative to be vigilant with the emergence of happy hypoxia among COVID-19 patients which can be a silent killer.

In this article, our team of resident consultant Chest Physicians/Physicians share their insights and expertise on ‘Happy Hypoxia’.

4. Symptoms of Happy Hypoxia

Happy hypoxia occurs when the oxygen concentration in the body drops to 95% or below. In normal conditions, if anyone has low body oxygen concentration, they will develop:

• Increase in breathing rate of up to 40-50 breath per minute
• Patient slowly develops difficulty in breathing and air hunger
• Patient become anxious and sweating occurs

However, in happy hypoxia, patients will remain calm, they will not exhibit these symptoms, thus it is difficult to detect if they have problems. This condition may prove lethal if it is not detected early. There are a few ways to detect happy hypoxia – with a pulse oximeter, with a smartwatch that can detect oxygen and pulse rate, or even with smartphones which have similar functions.

5. What Kind Of Exercise Would Be Recommended For COVID-19 Patients?

As we know, COVID-19 attacks the lungs, causing breathing problems. Breathing exercises are very important for COVID-19 patients. Breathing exercises will help to fasten recovery and increase lung capacity, leading to an improved quality of life.
