My mother with COPD cannot tell when her breathing is getting dangerously worse — what should we watch?

✓ Accepted answer

Watch for measurable changes in oxygen saturation, resting heart rate, and daily activity tolerance that occur over several days, as these objective markers reliably predict severe exacerbations before subjective symptoms escalate.

• Monitor pulse oximetry daily: Track resting oxygen saturation (SpO2) at the same time each day. A drop of 4 percent or more below her established baseline, or a sustained level below 88 percent, requires immediate contact with her pulmonologist. Keep the reading log visible to track trends rather than isolated moments.
• Measure peak flow and FEV1 if available: If she has a peak flow meter, record readings each morning. A decrease of 20 percent from her personal best indicates airway tightening. While home spirometers are rare, tracking peak flow provides a consistent numerical reference that bypasses unreliable self-reporting.
• Quantify rescue inhaler usage: Count every use of her short-acting bronchodilator. Using the inhaler more than four times a day, or needing it for shortness of breath that persists after two puffs, signals uncontrolled inflammation. This objective count is often ignored by patients who feel they are managing.
• Track daily functional milestones: Record specific tasks, such as walking to the mailbox or climbing one flight of stairs, that she can complete without stopping. Inability to perform these baseline tasks without significant pause or chest tightness is a concrete indicator of declining lung capacity.
• Assess sputum changes and fever: Note the color, volume, and consistency of mucus. A shift from white or clear to yellow, green, or rust-colored sputum, combined with a fever over 100.4 Fahrenheit, suggests infection. The CDC notes that respiratory infections are the leading cause of COPD hospitalizations, so prompt antibiotic evaluation is crucial when these signs appear.
