Proper Blood Oxygen Monitoring with Pulse Oximeter

Blood oxygen refers to the degree of binding between hemoglobin and oxygen in the blood, in other words, the maximum solubility of oxygen in the blood. Blood oxygen saturation represents the body's ability to bind and utilize oxygen.

As we all know, the human body maintains normal respiration and life activities by inhaling oxygen and exhaling carbon dioxide. Inhaled oxygen needs to bind with hemoglobin in red blood cells in order to be transported to the whole body for absorption and utilization by various tissues and cells.

Normal functioning of various organs and tissues in the body requires oxygen. Once organs and tissues in the body are deprived of oxygen, a series of problems may occur. Important organs such as the heart, brain, and lungs are particularly sensitive to oxygen deprivation, and symptoms such as dizziness, chest tightness, and shortness of breath may occur in the early stages of oxygen deprivation. Chronic oxygen deprivation can cause long-term damage to various organs. Prolonged oxygen deprivation may also lead to serious diseases such as myocardial infarction, cerebral infarction, pulmonary infarction, and even life-threatening situations.

It is worth noting that different people have different tolerances to oxygen deprivation, and many people may not have symptoms of discomfort even when their oxygen levels are low, which is the most dangerous situation. Therefore, it is important to use a pulse oximeter to monitor blood oxygen levels. The TeleRPM Pulse Oximeter (BLE) 2022 is a small, compact, simple, reliable, and durable physiological monitoring device used to check blood oxygen saturation (SpO2) and pulse rate.

Why use a pulse oximeter to measure blood oxygen?

Blood oxygen saturation is an important indicator of the blood's ability to carry oxygen, as well as an important parameter reflecting lung function, circulatory function, and other functions. Blood oxygen saturation, blood pressure, respiration, body temperature, and pulse are considered the five basic vital signs of life, and they are important pillars for maintaining normal life activities. Why should we regularly use a bluetooth pulse oximeter to monitor blood oxygen levels? A decrease in blood oxygen saturation can cause a series of harms to overall health, such as:

Impairment of lung function leading to lung diseases

Gas exchange between the body and the external environment occurs through the lungs. Human respiration includes three processes: external respiration, which involves ventilation and gas exchange in the lungs; transportation of gases in the blood; and internal respiration that occurs in tissue cells. When the lungs encounter problems, it will inevitably affect the supply of oxygen to the body. Similarly, when blood oxygen concentration decreases due to various reasons, it can also affect lung function.

Increased risk of cardiovascular diseases

The heart is the "pump" that drives blood circulation, and blood needs to carry oxygen in order to be transported to various parts of the body for normal functioning. A decrease in blood oxygen saturation can inhibit blood transport and the pumping function of the heart.

Repeated hypoxia in the body can result in a large number of red blood cells being unable to properly carry oxygen and participate in blood circulation, leading to the accumulation of red blood cells in blood vessels and an increased risk of thrombus formation. Once a thrombus detaches and blocks important blood vessels such as those in the heart or brain, it can easily trigger acute myocardial infarction or cerebral infarction. Prolonged hypoxia can also reduce myocardial contractility, leading to slowed heart rate, decreased cardiac output, degeneration, and necrosis of myocardial cells, and even heart failure.

Impact on Brain Function

The brain has the highest oxygen demand among all organs in the body and is also the most sensitive organ to hypoxia. Although the weight of the brain accounts for only 2% to 3% of body weight, the oxygen consumption of the brain accounts for 20% to 30% of the total oxygen consumption of the body. Brain tissue has a very low tolerance for ischemia and hypoxia, and when the blood and oxygen supply to the brain is interrupted, 1.9 million neurons die every minute.

Chronic hypoxia in the brain can cause symptoms such as drowsiness, poor concentration, and decreased memory. Prolonged or acute hypoxia can result in coma, convulsions, or even death. If accompanied by symptoms such as finger tingling, chronic cough, and other signs of decreased blood oxygen saturation, prompt medical treatment is necessary. Therefore, it is important to use a pulse oximeter for blood oxygen monitoring.
