The patient's vital capacity of 5 mL/kg is a contraindication for the use of incentive spirometry,and coupled with the fact that he is unable to cough effectively,this makes the use of deep-breathing exercises inappropriate.The patient's respiratory weakness plus the fact that there is no mention of excessive sputum make positive expiratory pressure therapy inappropriate.Intermittent positive-pressure breathing is appropriate because of the patient's low vital capacity and inability to cough effectively.
