dangerous symptoms and shortness of breath test

The fact that coro­n­avirus pri­mar­i­ly dis­rupts the func­tion­ing of the lungs has been known since the first days of the pan­dem­ic. The most accu­rate pic­ture of the con­di­tion of the lungs is giv­en by CT, but it is not always pos­si­ble and nec­es­sary to do an exam­i­na­tion. How to check the lungs at home so as not to miss dan­ger­ous symp­toms and at the same time not to give in to unnec­es­sary pan­ic?

How to check if everything is in order with the lungs

There are sim­ple home tests that allow you to assess the con­di­tion of the lungs and notice any prob­lems in the ear­ly stages.

Blow up a balloon

Lung vol­ume is an impor­tant para­me­ter that is respon­si­ble for the prop­er func­tion­ing of the organ. On aver­age, the vol­ume of lungs in a man is 3–3.5 liters, in a woman — 2.5–3 liters. Take an ordi­nary bal­loon. It must ini­tial­ly be inflat­ed and deflat­ed sev­er­al times to make the mate­r­i­al more elas­tic. Then fill your lungs with air — this can be done dur­ing the deep­est pos­si­ble breath — and inflate the bal­loon with one exha­la­tion. The vol­ume of the ball will clear­ly show what the vol­ume of the lungs is. The diam­e­ter of the ball must be at least 15 cen­time­ters. If less, then most like­ly the lungs are not work­ing at full capac­i­ty. There could be a num­ber of rea­sons for this, and it’s not just COVID-19.

Look at the fingers

Place your index fin­gers togeth­er. If the fin­gers look swollen and at the same time diverge, and the nails look like “watch glass­es”, then this may indi­cate a seri­ous prob­lem with the lungs.

Hold the breath

Tai­wanese doc­tors rec­om­mend check­ing your­self in this way every morn­ing. Take a deep breath and hold your breath for more than 10 sec­onds. If you do not expe­ri­ence any dis­com­fort while exhal­ing, then most like­ly there is no infec­tion in the lungs.



How to recognize shortness of breath

Res­pi­ra­to­ry fail­ure is deter­mined only by sat­u­ra­tion (oxy­gen con­tent in the blood). But in the cur­rent con­di­tions, we can wait a long time for a doc­tor to check sat­u­ra­tion, and not every­one has pulse oxime­ters. But you can check if you have dan­ger­ous short­ness of breath, and on your own.

Breathlessness test

Ask some­one close to count the fre­quen­cy of res­pi­ra­to­ry move­ments. One res­pi­ra­to­ry move­ment is inhala­tion + exha­la­tion, the amount must be count­ed per minute, being in a calm state. A healthy per­son has an aver­age of 14–17 move­ments. If more than 20 — this is a rea­son to be wary. Check your­self twice: if you do 20 move­ments or more each time in a minute, then this is short­ness of breath.

Impor­tant! Do not rush to do a CT scan of the lungs at the slight­est sus­pi­cion of a dis­ease — the deci­sion to con­duct a CT scan can only be made by a doc­tor with an appro­pri­ate clin­i­cal pic­ture.
