What should doctors do when vaping might be hurting someone's lungs?

Imagine you're a doctor, and a patient comes in struggling to breathe. They've been using e-cigarettes or vaping products, and you suspect that's what's hurting their lungs. What do you do next? That's the exact situation new health guidance is trying to address. It's not a study with results, but a set of interim recommendations for health care providers. The guidance is specifically for evaluating and caring for patients with suspected lung injury tied to vaping. Since this is an evolving situation, the guidance is based on what experts know right now. It's meant to be a helpful tool for doctors on the front lines, not a final answer. The full picture of what causes these injuries and the best way to treat them is still coming into focus.
