To determine outcome for a patient undergoing intermittent positive-pressure breathing (IPPB) therapy, the respiratory therapist should assess which of the following?
1. Peak expiratory flow
2. Breath sounds
3. Sputum color
4. Maximum inspiratory pressure

Assessment of outcomes for intermittent positive-pressure breathing include tidal volume meas-urement, FEV1, peak expiratory flows, cough assessment, chest radiograph review, and subjec-tive patient response. The color of the patient's sputum is not a determining factor in the outcome of intermittent positive-pressure breathing; it is an outcome assessment for the use of antibiotics. Maximum inspiratory pressure is not used in the determination of the effectiveness of intermit-tent positive-pressure breathing.
