Happy Hypoxia refers to the condition where the patient has low oxygen saturation, but does not feel any symptoms of low saturation. As a result, they do not get alarmed until the disease has progressed and there is severe damage to the lungs.
Younger patients often experience 'happy hypoxia' in which they do not feel any breathlessness or related symptoms till oxygen saturation levels fall below 81, because their immunity is high.
Due to increasing number of youngsters infected with Coronavirus during the current wave, doctors sounded an alert about 'happy hypoxia' among youngsters. There are newer symptoms like rash, diarrhoea, conjunctivitis, joint pains, but these are not mentioned in state or central protocol for RT-PCR testing.
Apart from high immunity, young adults are also exposed to the virus more, as they are economically active. Unlike youngsters, symptoms of hypoxia in older people appear at 92 saturation level.
