Track Your Oxygen Levels: Free Pulse Oximeter Readings Chart PDF

Track Your Oxygen Levels: Free Pulse Oximeter Readings Chart PDF

Easily log your SpO₂ and heart rate with this editable and printable PDF.

Checking your oxygen saturation and heart rate regularly can provide valuable insight into your health—especially if you're managing a respiratory condition or just want to stay ahead of potential concerns.

To help you organize your results and notice trends over time, we’ve created a fillable PDF you can use daily to track your pulse oximeter readings.

What a Pulse Oximeter Measures

A pulse oximeter is a compact, non-invasive device that provides two key readings:

  • SpO₂ (Oxygen Saturation): The percentage of oxygen-carrying hemoglobin in your blood.

  • Pulse Rate (BPM): Your heart rate in beats per minute.

These numbers can vary throughout the day, depending on activity, rest, or underlying health conditions. Tracking them over time helps you notice patterns—not just isolated numbers.

How to Determine Your Baseline Reading

Before you start tracking changes, it’s helpful to know your baseline—your typical oxygen level and pulse rate when you’re at rest and feeling well.

To find it:

  1. Take readings at the same time each day, ideally when you're relaxed (e.g., just after waking or sitting calmly).

  2. Record your results over three to five days.

  3. Use the average of those readings as your baseline.

There’s space at the top of the downloadable chart to record this for future comparison.

Understanding Your Readings at a Glance

Here’s a general reference for what your oxygen levels might indicate:

When to Consider Continuous Use

If you're managing a long-term condition, recovering from illness, or checking your oxygen levels during sleep or activity, continuous use of a pulse oximeter may be worth considering.

Unlike spot checks, continuous use:

  • Automatically logs readings over time

  • Can detect overnight drops in oxygen saturation

  • Reduces the need for manual data entry

  • Helps highlight patterns and red flags more easily

Frequently Asked Questions

What does a pulse oximeter measure?

A pulse oximeter measures two things: your SpO₂ (blood oxygen saturation) and your pulse rate in beats per minute. It's a small, non-invasive device that clips onto your finger.

What is considered a normal SpO₂ reading?

Generally, 95–100% is considered a normal range. Readings of 91–94% are considered mildly low, 86–90% moderate, and 85% or below is considered severe. These ranges are general guidelines and not a diagnosis. Always check with your healthcare provider about what's normal for you.

How do I find my baseline oxygen level?

Take readings at the same time each day while you're relaxed, such as right after waking up. Record your results over three to five days, then average them to find your baseline. You can note this baseline at the top of the tracking chart for future reference.

Can I fill out the tracking chart on my phone or computer?

Yes. The PDF chart is editable, so you can fill it out directly on a computer or mobile device, or print it out and complete it by hand.

What information does the tracking chart include?

The chart includes space for patient information (name, date of birth, age, baseline reading) along with a tracking table for date and time, heart rate, oxygen level, temperature, a status indicator (better/worse/same), and notes for symptoms or activity.

When should I consider continuous monitoring instead of spot checks?

Continuous monitoring may be worth considering if you're managing a long-term condition, recovering from illness, or want to track oxygen levels during sleep or activity. Unlike spot checks, it automatically logs readings over time, can catch overnight drops in oxygen, and reduces manual data entry.
