Pulse oximeter can help you check your body

The purpose of breathing is to deliver the amount of oxygen needed by the body cells for their normal operation, while also eliminating the carbon dioxide produced by these cells. Therefore, the human body needs oxygen to produce energy. Pulse oximeter or pulse oxygen saturation (SpO2) is a non-invasive test for measuring oxygen saturation in blood. Follow our guide to help you understand the role of pulse oximeter and pulse oximeter.

 

What is a pulse oximeter?
The pulse oximeter measures the amount of oxygen in the blood. If you are prone to or suffer from respiratory diseases, this measurement will enable you to monitor your health status.
Blood oxygen measurement is a non-invasive test, which means that the device can be used without damaging the skin. 
This is the website of our company: www.chinautech.com We can provide you with a suitable pulse oximeter

 

The pulse oximeter can quickly analyze the efficiency of oxygen delivery to the body parts farthest from the heart (such as fingers and toes).
The pulse oximeter can monitor people with various diseases that affect the oxygen in the blood, such as:
■ Chronic obstructive pulmonary disease (COPD),
■ Asthma,
■ Pneumonia,
■ Lung cancer,
■ Anemia,
■ Heart attack or heart failure,
■ Congenital heart defect.
This method can be used in various situations, including:
■ Determine if the lung medication has the expected effect,
■ Find out if a person needs breathing assistance
■ To monitor oxygen levels after or during surgery,
■ Determine the effectiveness of oxygen therapy,
■ To know if breathing ability is sufficient for physical activity,
■ Analyze apnea during sleep. This is oxygen saturation at night.
Our pulse oximeter can help you diagnose your physical condition. Details can be accessed on our official website: //www.chinautech.com/5264800193915309.html

 

How to use pulse oximeter?
The working principle of pulse oximeter is based on the ability of blood to absorb red light and infrared light, depending on oxygen saturation. The sensor placed at the end of the finger is equipped with a transmitter and a light receiver.

The pulse oximeter is composed of sensor, monitor and cable. Sensors are placed at fingertips, toes, and earlobes. There are suitable sensors in various parts of the human body.
The color of blood depends on the amount of oxygen it contains. Red and infrared beams of light can detect the oxygen content in the blood.

 

Although oxygen saturation varies from person to person, the normal value should be above 95%. However, saturation varies from person to person. When the oxygen saturation is greater than 95%, we call it good oxygen saturation. When SpO2 (oxygen saturation) is between 92% and 95%, saturation is considered correct. Insufficient saturation, below 90%, indicates that the patient is desaturating.

When the percentage of oxygen saturation (O2) decreases, we call it desaturation. According to the patient's pathology, values below 90% may be normal. This is the case in certain end-of-life clinical situations, such as in certain conditions such as pulmonary fibrosis.
