HIGH FREQUENCY VENTILATION AND REGIONAL COMPLIANCE

High frequency ventilation and regional compliance.

Persistent clinical demand and recent industrial developments show that High Frequency Ventilation is well established, although the method was introduced prematurely into clinical use, with incomplete knowledge, primitive instrumental development and inadequate monitoring standards. The confusion [1-6] in the literature regarding the clinical use of high frequency ventilation and its merits in...

Specific 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...

High - frequency Jet Ventilation

High-frequency jet ventilation (HFJV) describes a technique of mechanical respiratory support based on the delivery of gases under conditions of constant flow and low pressure. Among the benefits ascribed to HFJV are lessened interference with hemodynamic function and reduced danger of barofrauma. The theoretical and technical aspects of HFJV are discussed and the clinical experience with 39 pa...

Distribution of ventilation and frequency-dependence of dynamic lung compliance.

High-frequency percussive ventilation revisited.

High-frequency percussive ventilation (HFPV) has demonstrated a potential role as a rescue option for refractory acute respiratory distress syndrome and as a method for improving inhalation injury outcomes. Nevertheless, there is a lack of literature examining the practical application of HFPV theory toward either improving gas exchange or preventing possible ventilator-induced lung injury. Thi...
