As we have previously explained, a life threatening situation requires that the Laws of Shabbat be suspended, and therefore we are allowed (or obligated) to do anything we believe is necessary to try to save a life, even if that implies violating the sanctity of Shabbat (see here).
1. In a situation where one estimates that Shabbat should be violated in order to save a life, it is forbidden to ask for a rabbinic opinion, because the time spent in that consultation might be essential to save a life (Yalqut Yosef, 191). Therefore it is a Mitsva for every Jew to help and assist a person when we suspect that a life is in danger.
2. In a case where a person has violated Shabbat trying to save a life and then, the patient died, or the patient suddenly recovered. Or if, for example, one brings his car to take a patient to the hospital and when he gets there he sees that someone else has already taken the patient to the hospital, in all these and similar cases, the person who violated Shabbat trying to save a life has done a Mitsva. Even thought he did not succeed in saving a life or even when he found out in hindsight that his assistance was unnecessary. This person will be rewarded by God for his good intention and, needless to say, he does not need to do Teshuba for violating Shabbat (Yalqut Yosef, 199).
3. In a case of a life threatening situation (hole sheyesh bo sakana) there is no need to perform the forbidden activities (melakhot) in an unusual way ('al yede shinuy) to attenuate the status of the violation. Because in life threatening situations the observance of Shabbat is suspended (hutra) and not just deferred (dehuya).
