When assessing for outcome from incentive spirometry, the respiratory therapist is looking for the absence of or an improvement in signs of atelectasis. These signs are decreased respiratory rate, resolution of fever, normal pulse rate, improved breath sounds, a normal chest radiograph, im-proved arterial oxygenation, increased vital capacity and peak expiratory flows, return of func-tional residual capacity or vital capacity to preoperative values, and improved inspiratory muscle performance.
