Respiratory input impedance during high frequency oscillatory ventilation.
Total respiratory input impedance (Zrs) measured by forced excitation may be computed easily from pressure and flow measurements recorded at the airway opening. The purpose of this paper was to analyse how the information provided by Zrs may be used for monitoring ventilatory mechanics during high frequency oscillatory ventilation (HFOV). We measured impedance (0.125-32 Hz) in six dogs, and in ...
متن کاملLung volume recruitment acutely increases respiratory system compliance in individuals with severe respiratory muscle weakness
The aim of the present study was to determine whether lung volume recruitment (LVR) acutely increases respiratory system compliance (Crs) in individuals with severe respiratory muscle weakness (RMW). Individuals with RMW resulting from neuromuscular disease or quadriplegia (n=12) and healthy controls (n=12) underwent pulmonary function testing and the measurement of Crs at baseline, immediately...
متن کاملSpecific compliance and gas exchange during high-frequency oscillatory ventilation.
OBJECTIVES To evaluate the use of specific compliance (static compliance/functional residual capacity) to adjust mean airway pressure, resulting in optimal gas exchange during high-frequency oscillatory ventilation in a surfactant-deficient newborn piglet. DESIGN Prospective controlled animal study. SETTING Laboratory. SUBJECTS Eight newborn piglets at 5 days of age. BACKGROUND High-fre...
متن کاملInterrupter airway and tissue resistance: errors caused by valve properties and respiratory system compliance.
The interrupter technique is used to determine airway and tissue resistance. Their accuracy is influenced by the technical properties of the interrupter device and the compliance of the respiratory system. We investigated the influence of valve characteristics and respiratory system compliance on the accuracy of determining airway and tissue resistance by means of a computer simulation. With de...
متن کاملAirway Resistance and Lung Compliance
Lung compliance may be defined as the volume change per unit pressure change.8 It is an expression of the elastic-like properties of the lung if it is measured at points on a pressure-volume curve at which air is not moving into or out of the lung. These points of no air-flow occur near the end of inspiration and again near the end of expiration. Compliance does not include air resistive change...
