COPD Symptom Tracker Template: Daily CAT Score, SpO2, Breathlessness

A Daily Tracker Built Around the Scales Your Pulmonologist Actually Uses

If you have COPD, you already know the pattern. Good days and bad days, with the bad ones hitting harder than the day before could have predicted. A sudden shift in sputum color. A morning where the usual walk to the mailbox leaves you breathing like you ran a race. An exacerbation that you did not see coming until you were already calling the clinic. This COPD symptom tracker template is designed to help you do exactly that.

The scales your pulmonologist uses to measure COPD are the CAT score and the mMRC dyspnea scale. Both are short, both have been validated in clinical research, and both give you a number you can track over time so that a bad week is visible as a bad week, not just a feeling. This template uses both, and it adds daily flare signals so you catch an exacerbation earlier than you otherwise would.

Why the CAT and mMRC Scales Are Worth the Few Extra Minutes

The COPD Assessment Test was developed as a short validated tool to measure the impact of COPD on wellbeing and daily life. It has eight items covering cough, phlegm, chest tightness, breathlessness on stairs, activity limitation, confidence leaving home, sleep, and energy. Each item is scored 0 to 5, so the total ranges from 0 to 40. A CAT score of 10 or less is considered low impact, 11 to 20 is medium, 21 to 30 is high, and above 30 is very high.

The mMRC is simpler. It is a single 0 to 4 grade based on when breathlessness stops you during daily activity. 0 is breathless only with strenuous exercise, 4 is too breathless to leave the house or breathless dressing. The Global Initiative for Chronic Obstructive Lung Disease, known as GOLD, uses both scales to help classify COPD severity and guide treatment decisions.

Tracking both weekly gives you and your pulmonologist a standardized picture that any clinician can read in seconds.

What to Log Each Day

Rescue Inhaler Use

Number of puffs of your short acting bronchodilator in the last 24 hours. This is one of the most sensitive daily markers. A steady climb in rescue inhaler use over three or four days is an early signal of an impending exacerbation.

Sputum Color and Volume

Clear, white, yellow, green, rust, or brown. Volume as none, small, medium, or large. A change in color from clear or white to yellow or green, especially with increased volume, is one of the Anthonisen criteria that pulmonologists use to define exacerbations.

Cough and Chest Tightness

Rate each 0 to 3 compared to your baseline. 0 is normal for you, 3 is much worse than normal.

Breathlessness at Usual Activity

Rate 0 to 3 based on a daily task you do every day, like climbing your own stairs or walking to the kitchen. Using a consistent task gives you a stable comparison.

Peak Flow If You Have a Meter

If you own a peak flow meter, take one reading at the same time each day and write it down. Peak flow is more established in asthma than COPD, but it can add useful information if you have one.

The Daily COPD Log

Once a week, calculate your CAT score by answering the eight CAT items, which your pulmonologist can give you or which are widely available online. Write the total in the margin of the sheet and on a running monthly CAT graph.

When to Act on What the Log Is Showing

A CAT score that climbs by 2 or more points from one week to the next is a signal to pay closer attention. A CAT score that climbs by 4 or more points is often a conversation to have with your clinic. Two or more rescue inhaler puffs per day above your usual baseline, a change in sputum color, or a new fever are all signals that your COPD action plan should be reviewed and possibly activated.

The point of logging these things is not to live in fear of every bad day. It is to give yourself and your care team early warning so an exacerbation can be caught before it becomes a trip to urgent care or the hospital.

For a digital version with automatic CAT score calculation and trend graphs, the COPD Tracker App captures the daily log and your weekly scores in one place.

What 30, 60, and 90 Days of Tracking Reveals

The first month gives you a clear baseline of your normal. The second month usually catches at least one minor flare, which teaches you what the early warning pattern looks like for your own body. By 90 days you will have enough data to see seasonal patterns, the impact of specific triggers like air quality or weather, and the long term trajectory of your symptoms across the period.
