Who knows if the containment measures of the second wave will prove effective: in the meantime, for at least fifteen days, following the last Prime Minister‘s Decree, Lombardy has returned to being a great ” red zone “, including the province of Brescia. We will see what will happen in the coming weeks: in the meantime, in a territory that all in all – at least for now – is holding up the fury of Covid, we can only express the utmost solidarity and closeness to the “cousins” of Milan, Brianza and the province of Varese ( the areas currently most in difficulty).

In view of the long health emergency, it is good to have at hand – as far as possible, mind you – also tools to prevent contagion, which allow us to check at home if something is wrong. Without forgetting, of course, that our reference in case of suspicious symptoms must always be our general practitioner or family pediatrician.

How the oximeter works

Today we are talking about the oximeter, also known as a pulse oximeter (or pulse oximeter) and oximeter: it is a non-invasive medical device that allows you to measure the oxygen saturation in peripheral arterial blood (SpO2) and at the same time also check the frequency. Unusual and low oxygenation, in fact, could be considered one of the first symptoms of Covid-19.

Values ​​above 96% are to be considered normal; between 95 and 93% are indicative of possible oxygenation problems (mild hypoxia); between 92 and 90% are indicative of insufficient oxygenation; below 90% is not physiological and indicate severe oxygen deficiency (severe hypoxia).
