A pulse oximeter is a small device that measures the oxygen saturation level (SpO₂) in your blood and your pulse rate, typically using a fingertip sensor.
What It Does
Measures oxygen saturation (SpO₂): This indicates how much oxygen your blood is carrying compared to its full capacity.
Tracks pulse rate: It also shows your heart rate in beats per minute.
📊 Normal Readings
SpO₂ levels: Typically range from 95% to 100% in healthy individuals.
Pulse rate: Varies by age and activity, but for adults, a normal resting rate is 60–100 beats per minute
🏥 Common Uses
Medical monitoring: Used in hospitals, clinics, and ambulances to monitor patients with respiratory or cardiac conditions.
Home use: Helpful for people with chronic conditions like COPD, asthma, or sleep apnea.
Fitness and altitude: Athletes and climbers use it to monitor oxygen levels during intense activity or at high elevations
