Kolkata: The state government directed the authorities to undertake "a six minutes walk test" in a medically supervised condition to predict silent hypoxia in Covid patients for early intervention to ensure better treatment.
The time for the "walk test" will be three minutes for people above 60 years of age.
In this connection the state Health and Family Welfare department has issued an advisor on protocol management for Covid patients on September 15.
Doctors will take subsequent steps if the patient is found panting while taking the "six minutes walk test" besides checking the person's oxygen level using pulse oximeters.
The state government has created a mammoth infrastructure to fight against Covid and a team of experts has been set up to advise necessary steps to provide better treatment to Covid patients.
