Respiratory mechanics in mechanically ventilated patients.
Respiratory mechanics refers to the expression of lung function through measures of pressure and flow. From these measurements, a variety of derived indices can be determined, such as volume, compliance, resistance, and work of breathing. Plateau pressure is a measure of end-inspiratory distending pressure. It has become increasingly appreciated that end-inspiratory transpulmonary pressure (str...
متن کاملBreathing cardiovascular variability and baroreflex in mechanically ventilated patients.
Heart rate and blood pressure variations during spontaneous ventilation are related to the negative airway pressure during inspiration. Inspiratory airway pressure is positive during mechanical ventilation, suggesting that reversal of the normal baroreflex-mediated pattern of variability may occur. We investigated heart rate and blood pressure variability and baroreflex sensitivity in 17 mechan...
متن کاملComponents of respiratory resistance monitored in mechanically ventilated patients.
The interrupter technique is commonly adopted to monitor respiratory resistance (Rrs,int) during mechanical ventilation; however, Rrs,int is often interpreted as an index of airway resistance (Raw). This study compared the values of Rrs,int provided by a Siemens 940 Lung Mechanics Monitor with total respiratory impedance (Zrs) parameters in 39 patients with normal spirometric parameters, who we...
متن کاملBronchoscopy in Mechanically Ventilated Patients
The origins of bronchoscopy date back to 1897 when Gustav Killian, considered “the father of bronchoscopy”, performed the first airway examination with a rigid esophagoscope to a farmer extracting a piece of bone that had lodged in the main stem bronchus. Shigeto Ikeda in 1964 revolutionized the field of bronchoscopy with the introduction of a flexible instrument that could be introduced to sub...
متن کاملEvaluation of the Effect of Nebulized N-Acetylcysteine on Respiratory Secretions in Mechanically Ventilated Patients: Randomized Clinical Trial
Background: The purpose of our study was to evaluate an inexpensive and available method to reduce mucous impactions in mechanically ventilated patients.Methods: This randomized clinical trial was conducted on 40 mechanically ventilated patients aged 15-90 years. The patients were randomly allocated into two arms; 20 cases and 20 controls. The cases received N-acetylcysteine via their nebulizer...
