In emergencies, care is guided by implied consent. This means you treat to preserve life or prevent serious harm even when the patient can’t give explicit permission, because a reasonable person would consent to necessary, life-saving care in that situation. Implied consent is what justifies starting therapy like CPR, hemorrhage control, or emergency surgery without waiting for a signed or spoken permission.

This differs from voluntary consent, which is a free, deliberate agreement by the patient to undergo a specific treatment. Express consent is the explicit confirmation given, often in writing or a clear verbal agreement. Informed consent adds understanding of risks, benefits, and alternatives, ensuring the patient is aware before agreeing. In emergencies, the priority is timely action, with the assumption of consent to avoid harm unless there’s clear evidence the patient would refuse or cannot be treated otherwise. If the patient regains capacity or there’s an established advance directive or known refusal, those preferences guide subsequent decisions.
