Pulse Oximeter for Sale

A pulse oximeter is a small, non-invasive medical device used to measure the oxygen saturation level in your blood, often referred to as SpO2. It’s a simple and painless test that involves placing the device on a thin part of your body, such as a fingertip or earlobe.

Here’s a breakdown of how a pulse oximeter works and its key features:

1. Measurement Principle: The device emits light wavelengths that pass through your skin and blood vessels. Oxygen-rich hemoglobin absorbs light differently than oxygen-poor hemoglobin. By analyzing the light absorption, the pulse oximeter can determine the proportion of oxygenated hemoglobin in your blood.
2. Oxygen Saturation (SpO2) Reading: This is the percentage of hemoglobin molecules carrying oxygen compared to the total hemoglobin in the blood. A normal SpO2 level is typically between 95% and 100%.
3. Heart Rate Monitoring: Pulse oximeters also measure your heart rate (pulse) by detecting the rhythmic changes in blood volume within your arteries.
4. Display: Most pulse oximeters have a digital display that shows your oxygen saturation level and heart rate in real-time. Some may also display a waveform representing your pulse.
5. Portable and easy to use: pulse oximeters are compact, battery-operated devices suitable for use at home, in clinics, or in hospitals. Healthcare providers and individuals with respiratory conditions such as asthma, COPD, or during recovery from surgery frequently utilize them.
6. Accuracy: While generally accurate, factors like nail polish, cold fingers, or poor circulation can affect readings. Calibration and proper placement are important for reliable results.
7. Application: Pulse oximeters are invaluable for quickly assessing respiratory function and oxygenation in emergency medicine, intensive care, and outpatient settings. They are also increasingly used by athletes to monitor oxygen levels during training.

Overall, pulse oximeters provide a vital snapshot of your blood oxygen levels and heart rate, offering crucial information for assessing respiratory health and overall well-being.
