The skin often becomes cool and mottled, and loses its turgor. The person may perspire and edema may develop. Cyanosis or a bluish tinge to nailbeds, lips, and skin may occur as a result of cardiac and respiratory deficiencies. If perspiration is excessive, indomethacin or steroids may help. The pulse rate usually increases and is weak and irregular.
Blood pressure decreases.
But there is no need at this time to take vital signs, orders and usual procedures notwithstanding. Death usually comes simply as cessation of life. The person stops breathing and the heartbeat ceases. The struggle is over. This is what we do when there is nothing else to do, and it is a great gift.
