A pulse oximeter non-invasively measures the proportion of oxyhemoglobin in the blood using optical principles, monitoring blood oxygen saturation in real time.
Daily Applications
• Home Health Monitoring: Conveniently measure blood oxygen levels at home using a finger-clip pulse oximeter.
• Chronic Disease and Elderly Care: Helps patients with asthma, COPD, or cardiovascular disease, as well as the elderly, prevent hypoxemia.
• Special Environment Reference: Used for health management during high-altitude mountaineering.
• Daily Exercise and Screening: Assists in screening for sleep apnea and monitoring exercise load.
Medical Applications
• Clinical Emergency and Monitoring: Continuously monitors vital signs of injured and critically ill patients in hospital emergency rooms and during surgery.
• Disease Diagnosis Support: Helps doctors accurately understand the condition, providing diagnostic and treatment references for diseases such as COVID-19, pneumonia, or heart failure.
• Identifying Silent Hypoxia: Monitors the subtle phenomenon of "happy hypoxia" during infectious disease outbreaks, preventing the condition from worsening.
Normal and Abnormal Standards
• Normal Range: The normal blood oxygen saturation value for healthy individuals is generally 95% or higher. • Low blood oxygen warning: If the value is below 90%, it usually indicates insufficient oxygen supply to the body tissues, and oxygen therapy or medical attention should be sought immediately.
