Fiabilité de la saturométrie pulsée chez les patients en état de choc. Les capteurs digitaux standard ne sont pas fiables sur les sites faciaux !

In patients with a shock receiving vasoconstrictive catecholamines, the reliability of SpO2 measurements with standard sensors appears better for fingers than for toes and face locations. These standard sensors should be discouraged for facial measurement because of their low reliability, even when the plethysmographic curve seems correct. Sensors specifically designed for each facial site exist, and their reliability should be estimated in patients receiving vasoconstrictive catecholamines.
