Armed YX300 pulse oximeter

The Armed YX300 pulse oximeter is designed for one-time measurements and short-term monitoring of oxygen saturation of capillary blood.

This device is widely used in hospitals (including clinical use in therapy, surgery, anesthesia, resuscitation); at home for self-control by patients suffering from chronic diseases of the respiratory and cardiovascular systems, people who have had a heart attack during the rehabilitation period; fitness centers to control physical activity. Athletes can use a pulse oximeter to quickly monitor their exercise levels. During physical exertion, the muscles burn oxygen and the level of saturation of arterial blood with oxygen falls.

Also recommended for patients receiving oxygen therapy.
