Hemodynamic and Oxygen Transport Characteristics of Common Ventilatory Modes: Measurements
Right heart catheterization was performed using a 7F Swan-Ganz catheter (Edwards Laboratories, Santa Ana, Calif) inserted percutaneously via an internal jugular or subclavian vein. All measurements were done while in supine position with the zero pressure taken as the atmospheric pressure at the midaxillary level. All values were recorded at end expiration. The CO was […]
Hemodynamic and Oxygen Transport Characteristics of Common Ventilatory Modes: Patients
This study was approved by our Institutional Review Board. Each patient or their next of kin signed a written informed consent form. We studied 12 patients admitted to the medical intensive care units (Veterans Affairs and University of Cincinnati Medical Centers) who were already on mechanical ventilatory support and were being hemodynamically monitored as determined […]
Hemodynamic and Oxygen Transport Characteristics of Common Ventilatory Modes
Assist control ventilation (ACV), synchronized intermittent mandatory ventilation (SIMV), and pressure support ventilation (PSV) are the three most conventional and commonly used modes of ventilatory support in patients requiring mechanical ventilation. The latter two modes are, in addition, applied very frequently to wean patients off ventilatory support. The PSV augments the patient’s spontaneous breaths with […]
Comparison of Intrapulmonary Percussive Ventilation and Chest Physiotherapy: Appendix
Furthermore, the magnitude of the differences observed herein was small and without clinical importance. This is especially reassuring as the sample size in any pilot study is limited and large or meaningful differences might not be detected, given the comparatively reduced statistical power provided. Canada health and care mall review This is not the case […]
Comparison of Intrapulmonary Percussive Ventilation and Chest Physiotherapy: Conclusion
There are few published studies that examine the efficacy and safety of IPV in clinical settings. In a study involving ventilator-dependent patients with adult respiratory distress syndrome, patients ventilated with the IPV-1 had significantly better oxygenation and improved carbon dioxide elimination compared with those patients receiving conventional ventilation at the same positive end-expiratory pressures and […]
Comparison of Intrapulmonary Percussive Ventilation and Chest Physiotherapy: Discission
No direct relationship between disease severity and response to any respiratory treatment was observed, except for patients receiving IPV. In that case, more severe disease was significantly correlated with greater improvement in FEF25-75 1 h after treatment (r2=0.47, p=0.04), but these differences disappeared by 4 h. Overall, the respiratory treatments had little differential effects on […]
Comparison of Intrapulmonary Percussive Ventilation and Chest Physiotherapy: Results
To compare the effects of standard treatment to IPV and to HVA/IPV, within-person statistical analyses were performed for both PFTs and sputum properties. For PFT comparisons, pretreatment and posttreatment PFTs were calculated as percentage of predicted, based on age-appropriate Morris et al or Polgar et al standards for each participant during each treatment. Then the […]
