Pulse Oximeter: Monitoring Heart Rate and Oxygen Levels

Understanding Pulse Oximeters

A pulse oximeter is a vital tool for monitoring heart rate and blood oxygen levels, especially during the COVID-19 pandemic.

  • Function: Measures heart rate and blood oxygen levels by shining light on the finger.
  • Accessibility: Affordable and user-friendly.

Using a Pulse Oximeter

Here's a step-by-step guide on using a pulse oximeter:

  1. Preparation: Remove nail polish/false nails and warm hands if cold.
  2. Procedure: Rest hand on chest at heart level, switch on oximeter, and place on finger.
  3. Stabilization: Wait for reading to stabilize (at least a minute).
  4. Recording: Record highest result after stable reading (for five seconds).

Monitoring Guidelines

Follow these guidelines for effective monitoring:

  • Frequency: Take readings three times daily, ideally at consistent times.
  • Documentation: Record readings, symptoms, and overall feeling on paper or online sheets.

Interpreting Results

Understanding the significance of blood oxygen levels and heart rate:

  • Ideal Levels: Blood oxygen: 95% - 99%; Heart rate: 50 - 90 bpm.
  • When to Seek Help: Contact a Doctor if blood oxygen falls to 93-94%, or seek emergency services if it drops below 92%.
