Why should I continue monitoring my sleep after being diagnosed with sleep apnea?

A sleep apnea diagnosis provides important information, but it does not show how the condition or its treatment may change over time. Ongoing monitoring can reveal trends in oxygen levels, breathing disturbances, heart rate variability, and sleep quality that may not be apparent from symptoms alone. These patterns can help show whether CPAP, an oral appliance, positional therapy, weight loss, or another treatment is working consistently. Long-term sleep data can also give patients and healthcare providers useful information for discussing changes or possible treatment adjustments.
