BRAUN 1 YK-81CEU Pulse oximeter with OLED display

Manifestation of respiratory disease.
A key symptom of respiratory disease is reduced lung function, which can lead to reduced blood oxygen levels. Blood oxygen saturation is an important indicator of a healthy respiratory system. When we breathe air, our lungs carry oxygen to the heart, which then pumps it throughout the body. If the capacity of the lungs deteriorates, the oxygen saturation of the blood decreases, which can endanger the organs.
For adults and children.
The device is intended for adults and children from 12 years of age (the measurement must be performed under the supervision of an adult).
