全球脉搏血氧仪市场前景预测(2020-2025年)
Pulse oximetry is a non-invasive and painless test that measures the patient’s oxygen
saturation level or the oxygen level in the blood without taking a blood sample. It
can rapidly detect even small changes in how efficiently oxygen is being carried to
the extremities furthest from the heart, including the legs and the arms. The pulse
oximeter is a small, clip-like device that attaches to a body part, such as toes or an
earlobe. It is used medically by patients with asthma, chronic obstructive pulmonary
diseases (COPD), chronic obstructive airway diseases (COAD), and other respiratory
conditions. It is most commonly put on a finger and is often used in a critical care
setting, such as emergency rooms or hospitals. Some doctors, such as
pulmonologists, may use it in office.
