Nearly 50% of infected patients being rushed to Lok Nayak Hospital, the biggest Covid-dedicated healthcare facility in Delhi, have 70% or lower levels of oxygen saturation at the time of admission.
The normal level of oxygen carried in red blood cells in a healthy adult is 96-98%. In elderly people or those with pre-existing respiratory health problems, it can be 94% and above.
While a fall of 3-4% from the normal level is considered serious and necessitates medical intervention, critical care experts said many people wait longer at home leading to complications and a higher risk of death due to Covid-19.Dr Suresh Kumar, medical director of Lok Nayak Hospital, said nearly half of patients come to the hospital when oxygen saturation has already dipped to dangerous levels, which is 70% or less. “We put them on oxygen supplementation immediately. But, by then, the heart and the brain are already affected,” he added.
