Pulse Oximeter

A TFT (Thin-Film Transistor) oximeter is a small, portable medical device used to measure a person’s blood oxygen saturation (SpO₂) and pulse rate quickly and non-invasively.

Key Features:

• TFT Display: Provides a clear, bright, and colorful screen that shows readings in an easy-to-read format. The display may also show waveform graphics like a plethysmograph.

• Pulse Oximetry: Measures the percentage of oxygen-saturated hemoglobin in the blood.

• Heart Rate Monitoring: Displays the user’s pulse rate in beats per minute.

• Compact and Portable: Small and lightweight, ideal for home use, clinics, or during travel.

• Easy to Use: Typically finger-clip design; simply place on a fingertip, press a button, and the readings appear in seconds.

• Battery Operated: Usually powered by AAA batteries, ensuring portability.

• Automatic Shut-off: Conserves battery by turning off automatically after a period of inactivity.

• Additional Indicators: Some models display low battery warnings, pulse strength, and measurement quality.

Uses:

• Monitoring oxygen levels for people with respiratory conditions such as asthma, COPD, or COVID-19.

• Fitness and sports monitoring to check oxygen levels during training or high-altitude activities.

• Home health monitoring for the elderly or patients recovering from illness.
