The fingertip blood pulse Oxymètre is a small instrument that is clamped on the finger to monitor the oxygen level in the blood. This kind of equipment, which was originally only available in the hospital, suddenly began to attract everyone's attention because of the COVID-19 pandemic.

Bien que les oxymètres de pouls du bout des doigts soient couramment utilisés dans les hôpitaux, l'intérêt de les utiliser à la maison pour les personnes en bonne santé est limité. Des problèmes d'équipement ou une utilisation incorrecte peuvent entraîner des lectures inexactes, il n'est donc pas sage de se fier uniquement aux oxymètres de pouls sanguin du bout des doigts sans le soutien diagnostique complet du personnel médical.

1. What is the use of a fingertip blood pulse Oxymètre?

The fingertip blood pulse Oxymètre is very small. After clamped on the finger, it can measure the pulse and the percentage of oxygen in the blood by shining light on the finger. The normal blood oxygen saturation of a healthy person is about 95 to 100%. There may be lung disease if the oxygen level is below this level. A level below 92% (88% for chronic obstructive pulmonary disease - COPD) indicates a serious condition and may require supplemental oxygen or hospital monitoring.

The fingertip blood pulse Oxymètres have been a common medical device since the 1970s. They are most commonly used for people with respiratory diseases, and sometimes for athletes and pilots who must monitor blood oxygen levels. They are mainly used for clinical testing and monitoring, but they may also be used at home for certain groups of people.

2. Can the fingertip blood pulse Oxymètre diagnose COVID-19?

The answer is negative. A Oxymètre de pouls du bout des doigts may detect a problem with blood oxygen levels, which may be related to the coronavirus, but it is only part of a comprehensive diagnosis. Blood oxygen saturation can help clinical decision-making, but it cannot replace clinical evaluation, nor can it replace the diagnosis process.

Some doctors suggest that for patients with suspected symptoms of COVID-19, whose state of illness is not serious so they don't need to be hospitalized, they can consider using fingertip blood pulse Oxymètres for monitoring at home.
