La saturation en oxyg\u00e8ne est un crit\u00e8re primordial pour rester en vie. Ce gaz demeure indispensable pour l’organisme \u00e0 tout instant. Plusieurs techniques permettent de surveiller sa pr\u00e9sence, mais surtout la quantit\u00e9 dans le sang.
\n<\/p>\n

Gr\u00e2ce \u00e0 l’oxym\u00e9trie de pouls<\/h2>\n

\"\"L’oxym\u00e8tre de pouls permet de mesurer la saturation en O2 dans l’organisme. Cet \u00e9quipement compact parvient \u00e0 \u00e9valuer le niveau d’oxyg\u00e8ne dans le sang gr\u00e2ce \u00e0 une technologie de pointe. Le doigt du patient est travers\u00e9 par une lumi\u00e8re infrarouge. L’appareil estime le taux de gaz vital et la quantit\u00e9 d’h\u00e9moglobine en se focalisant sur la transparence. Il en d\u00e9duit la saturation en mesurant la luminosit\u00e9. Chez une personne en bonne sant\u00e9, la concentration est d’environ 97 \u00e0 99 %. Cela signifie que la quasi-totalit\u00e9 des globules rouges transporte des mol\u00e9cules d’O2.<\/p>\n

Utilisation d’un appareil d’appoint<\/h2>\n

\"\"Accessible au grand public, l’oxym\u00e8tre de pouls est un appareil \u00e0 pile ou rechargeable. Son utilisation reste facile. Il suffit d’ins\u00e9rer un doigt ou la plante de pieds dans l’\u00e9quipement en forme de pince. Certaines parties du corps peuvent aussi servir si les autres sont gel\u00e9es par exemple. La mesure se fait instantan\u00e9ment d\u00e8s la pose de l’appareil d’oxym\u00e9trie. La saturation normale est \u00e0 99 %, mais elle reste tol\u00e9rable jusqu’\u00e0 97 %. Une personne en bonne sant\u00e9 peut \u00e9galement avoir 94 % de globules rouges op\u00e9rationnels. \u00c0 90 %, il faut agir puisque la personne souffre d’hypox\u00e9mie.<\/p>\n

Des m\u00e9thodes plus invasives existent \u00e9galement<\/h2>\n

\"\"Parfois, il est pr\u00e9f\u00e9rable d’utiliser une autre m\u00e9thode pour \u00e9valuer le taux d’O2 dans l’organisme. Il faudra notamment faire une prise de sang. C’est la SaO2 ou saturation art\u00e9rielle en oxyg\u00e8ne. La technique est particuli\u00e8rement fiable. Elle devient m\u00eame indispensable si le patient se pr\u00e9pare pour une op\u00e9ration chirurgicale ou une autre intervention lourde. La mesure de l’h\u00e9moglobine oxyg\u00e9n\u00e9e est importante dans diff\u00e9rentes circonstances. Cela dit, l’oxym\u00e9trie de pouls est d\u00e9conseill\u00e9e en cas d’hypertension et diverses pathologies.<\/p>\n","protected":false},"excerpt":{"rendered":"
