Utilization of pressure-volume curves in the pediatric patient.
Seven patients treated with continuous mechanical ventialtion were monitored with static and dynamic pressure-volume curves. Three patients developed no pulmonary complications, and mechanical ventilation was discontinued within 96 hr. In four patients, pressure-volume curves were used as a diagnostic aid in the detection of the physiologic defect resulting from bronchoconstriction, atelectasis, loculated pleural fluid, pulmonary edema, and mucous plugging. These measurements were also utilized to evaluate the effectivess of therapeutic modalities such as treatment of bronchoconstriction with bronchodilators, mucous plugging with adequate suctioning, and drainage of loculated pleural effusion. Pressure-v-lume measurements are simple, noninvasive, and require the smae equipment used in continuous mechanical ventilation. Pressure-volume monitoring of pediatric patients with curves warrants further investigation to evaluate its value.
