What is a finger pulse meter used for?

Introduction

A finger pulse meter, also known as a pulse oximeter, is a compact, non-invasive device that measures the oxygen saturation level (SpO2) and pulse rate in the blood. It's an essential tool for monitoring respiratory conditions and ensuring optimal oxygenation in various medical scenarios.

Understanding the Functionality of a Finger Pulse Meter

The finger pulse meter operates by emitting infrared light through the fingertip, which is absorbed differently by oxygenated and deoxygenated hemoglobin. A sensor measures the amount of light absorbed, and the device calculates the percentage of oxygenated blood based on this data.

Applications and Uses

Finger pulse meters are used in various settings, from hospitals and clinics to home healthcare. They are crucial for:

  • Monitoring patients with chronic respiratory or cardiovascular conditions.
  • Assessing the recovery of patients post-surgery or during anesthesia.
  • Evaluating the effectiveness of supplemental oxygen therapy.
  • Checking vital signs during physical activities and high-altitude travel.

Technical Specifications and Parameters

Finger pulse meters generally feature the following specifications:

  • SpO2 Range: 70% to 100%
  • Accuracy: ±2% for SpO2 levels between 80% to 100%
  • Pulse Rate Range: 30 to 250 beats per minute (bpm)
  • Resolution: 1% for SpO2 and 1 bpm for heart rate
  • Display: OLED or LED screen with waveform display
