unless relatively expeditious

Living wills represent the
chance for patients to declare their wishes in advance of situations in which
they become no longer competent to do so. They are revocable by the
patient at any time and are automatically invalid if the patient is pregnant,
as another being is involved. Living wills can be set aside if a long period
has elapsed since their drafting and the wishes are not known to be current.
Also, there is the potential for conflict if the patient has signed a donor card and prolongation of life would be needed to carry out those wishes. Generally,
such action would not be honored unless relatively expeditious
arrangements were possible.
