Pulse Oximeter

diagnostic tool that measures the oxygen saturation of the blood, and pulse

Pulse Oximeter

It may be used to monitor the health of individuals with any type of condition that can affect blood oxygen levels

asthma

COPD

pneumonia ...

Pulse Oximeter

 measures the change of light absorption in oxygenated or deoxygenated blood.

Multiple Choice

Oxygen readings using this device is due to the fact that

• O₂ diffuses into the blood from the bronchi, which is then carried by the veins to the cells

• O₂ diffuses into the capillaries from the alveoli, which is then carried by arteries to the cells

• CO₂ diffuses into the blood from the bronchi, which is then carried by the veins to the cells

• CO₂ diffuses into the capillaries from the alveoli, which is then carried by arteries to the cells
