Go through these in order and stop at the first one that applies. If you are reading this for someone else, answer for them.
Call emergency services for severe breathlessness at rest, blue or grey lips, confusion, fainting, severe chest pain, or inability to speak in full sentences.
These signs may mean the body is not receiving enough oxygen or another emergency is occurring.
If you have GIP, contact your healthcare team promptly if breathing is steadily worsening, you need more oxygen than usual, or daily activities have become noticeably harder.
New fever, productive cough, or chest discomfort also needs assessment because infection or another condition may be present.
Seek urgent same-day care for rapidly worsening breathlessness, new coughing of blood, or a major unexplained drop in your oxygen reading.
Arrange a routine appointment if you have persistent dry cough, increasing breathlessness during activity, or reduced exercise tolerance and currently work—or previously worked—with hard metals.
Bring material names or safety data sheets if available.
Every sign above is quoted from the sofidex article on Giant cell interstitial pneumonia. If you are not sure, err upward — it is always reasonable to be checked.
