|
Intrapulmonary percussive ventilation(IPV), developed by Forrest M. Bird, M.D., delivers high flow mini-bursts of air along with bronchodilator to the lung at a rate of more than 200 times per minute and has the theoretical potential for aiding in expectoration of secretions through internal percussion. To evaluate effects of IPV on respiratory therapy, we compared IPV with conventional chest physical therapy in patients with excess or retained pulmonary secretions. The results are follows. 1) There were no significant differences among the experimental group with respect to blood pressure, heart rate and respiratory rate.
2) Arterial oxygen tension was significantly increased after IPV. 3) ICU stay was slightly shortened in the experimental group as compared with that in the control group. However, there was no statistical significance. These results indicate that IPV may be effective in respiratory care of patients with excess or retained airway secretions. |
