Comparison of Intrapulmonary Percussive Ventilation and Chest Physiotherapy: Materials
Participants went without breakfast and received regularly prescribed oral medications, but did not receive home chest physiotherapy on each morning of the study. Pulmonary function testing (PFT), including forced vital capacity (FVC), forced expiratory volume in 1 s (FEVi), peak expiratory flow (PEF), and mean forced expiratory flow during the middle half of vital capacity […]
Comparison of Intrapulmonary Percussive Ventilation and Chest Physiotherapy: Methods
The two most salient innovations provided by IPV-1 with respect to its application in CF therapy include (1) the simultaneous combination of mechanical with pharmacologic interventions (aerosols) to mobilize endobronchial secretions, and (2) the development of a patient-operated device for chest physiotherapy which may allow greater independence for the adolescent and adult with CF. To […]
Comparison of Intrapulmonary Percussive Ventilation and Chest Physiotherapy
The management of the pulmonary complications of cystic fibrosis (CF) focuses on the enhancement of mucociliary clearance to optimize gas exchange and minimize infections due to mucostasis. Achieving this end involves the following: (1) removing mucus from the airways with mechanical or manual chest percussion and postural drainage (P&PD) and cough; (2) increasing airway caliber […]
Synchronized Intermittent Mandatory Ventilation With and Without Pressure Support Ventilation in Weaning Patients With COPD From Mechanical Ventilation: Appendix
This additional burden is not negligible: Katz and coworkers have shown that the respirator (Puritan Benett 7200) induces an additional inspiratory work ranging from 10 to 40 percent. Fiastro and coworkers predicted that a 1-mm decrease in the tube diameter results in a 67 to 100 percent increase in this work. Nevertheless, low PSV level […]
Synchronized Intermittent Mandatory Ventilation With and Without Pressure Support Ventilation in Weaning Patients With COPD From Mechanical Ventilation: Conclusion
Our study reassessed in patients with COPD the previously described effects of PSV on the breathing pattern. For PSV levels >12 cm H2O, group 1 patients exhibited significant lower sVe and Sf with higher sVt than did group 2 patients. However, despite this difference in sVe, there was no difference in blood gas values between […]
Synchronized Intermittent Mandatory Ventilation With and Without Pressure Support Ventilation in Weaning Patients With COPD From Mechanical Ventilation: Comment
Respiratory acidosis alone, even without clinical signs of respiratory muscle fatigue, was enough to return to the previous step. With PSV, the average weaning time showed a tendency to be shorter, but the difference between the two groups did not reach the significance level, which is not surprising given the small number of patients studied. […]
Synchronized Intermittent Mandatory Ventilation With and Without Pressure Support Ventilation in Weaning Patients With COPD From Mechanical Ventilation: Discussion
At the end of this study, all patients with COPD were extubated as they had undergone long periods of SB without clinical or/and blood gas value deterioration. The duration of the weaning period appeared lower in group 1 than in group 2: 4.2 ±0.8 days (SIMV/PSV) vs 5.3±1.0 days (SIMV), but the difference did not […]
