This tool stores only a simple tally in this browser. It is for timing oxygen use during attacks, not for medical diagnosis or long-term tracking. Mark when the pain stops, keep oxygen running, then finish the session when you stop oxygen. Many patients stay on oxygen for roughly twice the abort time to reduce rebound risk, especially when flow is lower.
If symptoms are unusual, severe in a new way, or you are worried, seek urgent medical care.
