Under what circumstances can consent be assumed for treatment?

Consent can be assumed for treatment when a passenger is unconscious, particularly in emergency situations. The underlying principle here is that individuals who are incapacitated and unable to give explicit consent due to their unconscious state are often assumed to require immediate medical intervention. This assumption arises from the ethical and legal notion of implied consent, which allows healthcare providers to act in the best interest of a patient whose life or health may be at risk. In these scenarios, it is generally considered that a rational person would consent to treatment if they were able to do so, particularly when lacking timely consent could lead to deterioration of their condition or even death.

In contrast, being awake or conscious does not imply consent for treatment. An individual who is alert may still refuse medical intervention. Additionally, while verbal agreement can indicate consent, it must be explicit and informed, rather than simply assumed based on physical presence or responsiveness. Therefore, in emergencies, assuming consent is primarily linked to patients who cannot provide it themselves due to their unconscious condition.
