Always assume the patient is revivable, do not give up. Check for pulse at the carotid artery. If, after two minutes you find no pulse check on the other side of the neck for two minutes. If there is any breathing or pulse, no matter how faint, do not give CPR but keep very close watch for changes in vital signs. If no pulse is found begin CPR immediately, stopping only when the heart begins to beat or the person applying CPR can not carry on any longer without endangering himself.
Medical help is imperative, hospitalization is needed.
It is altogether too easy to cause more harm than good by using the wrong treatment. If one can not distinguish the level of hypothermia through visible signs and symptoms then he should assume severe hypothermia. Through recent research and clinical findings it has come to be concluded that the safest and most effective method of treating hypothermia is through inhalation rewarming. The necessary equipment for providing inhalation rewarming therapy in the field is now readily available. However, this equipment may not be available when it is needed and people who may end up in the position of having to provide treatment must know the alternative methods which have been described here.
