With regards to treating a Covid-positive affected person at dwelling, there may be loads of confusion as to which plan of action is one of the best, and the way one could make an individual really feel snug at dwelling, with out having to fret about getting admitted within the hospital.
It must be saved in thoughts that amongst different issues, there are some tell-tale indicators as to when hospitalisation is required. This features a six-minute stroll take a look at for sufferers who’re getting handled at dwelling and whose oxygen ranges are regular at room air and through resting. It is suggested the affected person walks within the room for six minutes at a traditional tempo and rechecks the oxygen ranges. If oxygen ranges drop after the stroll, then it’s an indication of early hypoxia and this affected person ought to search for beds within the hospital, or get an oxygen concentrator at dwelling with the recommendation of their physician.
Dr Sanjay Shah, guide, normal doctor, Fortis Hospital Mulund explains that oxygenation needs to be most well-liked when blood oxygen ranges (SpO2) readings drop under 94 per cent.
“Ideal oxygen levels should be between 95-99 per cent. While no oxygen therapy can instantly boost oxygen levels or restore them to normal, Covid patients should aim to achieve a saturation of up to 92 per cent. Achieving 100 per cent saturation shouldn’t be done when the body is sick. This may exhaust your resources quicker — whether it is a concentrator or cylinder that you use,” he says.
What’s an oxygen concentrator?
The physician goes on to clarify that an oxygen concentrator is an electronically operated system that separates oxygen from room air. It gives a excessive focus of oxygen on to you thru a nasal cannula. “These devices work on the principle of ‘rapid pressure swing absorption’, which is where the nitrogen is removed from the air using zeolite minerals which absorb the nitrogen, leaving other gases to pass through and capturing oxygen as the primary gas. The collected oxygen is 92-95 per cent pure.”
Issues to remember
Dr Shah says regular air could have 21 per cent oxygen. If 1-litre oxygen is supplied to the affected person by means of the concentrator, the oxygen share in lungs rises to 24 per cent, with 2 litres it rises to twenty-eight per cent, and with 10 litres, it rises to 60 per cent.
“There is a need for monitoring this from time-to-time to ensure the flow of oxygen is proper and the patient is not over oxygenated. Seek your doctor’s advice to decide how many litres per minute of oxygen is required for the patient. Keep a pulse oximeter handy to check oxygen levels from time to time.”
Who’s eligible for an oxygen concentrator?
In line with Dr Shah, “only mild to moderately-ill patients”, who’ve “an oxygen saturation level between 90-94 per cent”, ought to rely upon an oxygen concentrator and may use it at dwelling.
“We must understand hoarding of such life-saving equipment will only worsen the country’s problem. Anyone with oxygen saturation depleting below 80-85 per cent may need a higher flow of oxygen and will have to switch to a cylinder or liquid medical oxygen supply and may eventually need hospitalisation,” he cautions.
