A life saving procedure on a patient and he is not giving consent

we want to do a life saving procedure on a patient and he is not giving consent… Can we do?. If we cant ;how is it different from sort of suicide…its like we are assisting him in his suicidal act.

Yes you can do if no representative is present around and the operation is done for patients dire need. Though the informed consent can be taken from him or first degree relative at the earliest.

f he himself is denying… Den…

If he denies take a informed consent too
Matter discussed , explained about the benefitsbof the procedure and implication on health . And also discussed about the implications of not doing the procedure.
Take consent for denial also.
Rest patient must take his own responsibility.

Den how is it different from suicide…are we assisting him in suicide
