Hemodynamic effects of intermittent manual lung hyperinflation in patients with septic shock.
OBJECTIVE The purposes of this study were to investigate the hemodynamic changes induced by intermittent manual lung hyperinflation (MHI) and to assess if these changes are adverse enough to warrant prohibition of MHI as a routine procedure in the care of patients with septic shock. DESIGN The study's design was experimental prospective. SETTING The settings were university hospital intensi...
متن کاملLung hyperinflation: foe or friend?
Breath-hold divers employ glossopharyngeal insufflation (GI) in order to prevent the lungs from compressing at great depth and to increase intrapulmonary oxygen stores, thus increasing breath-hold time. The presented case study shows the physiological data and dynamic magnetic resonance imaging (dMRI) findings of acute hyperinflation, deliberately induced by GI, in a breath-hold diver and discu...
متن کاملLung hyperinflation in airway obstruction.
*Dept di Science Motorie, University of Genova, I-16132 Genova, Italy. +Division de Pneumologie, Centre Hospitalier Universitaire Vaudois, CH-1011 Lausanne, Switzerland. Since the early studies with inert gas dilution techniques, it has been known that residual volume and functional residual capacity are increased in patients with pulmonary emphysema [1] or acute asthma [2]. These findings were...
متن کاملHemodynamic effects of manual hyperinflation in critically ill mechanically ventilated patients.
SUBJECT OBJECTIVE To assess the hemodynamic effects of manual lung hyperinflation in mechanically ventilated patients and to measure the different inspiratory pressures and tidal volumes generated by different operators. DESIGN Measurements of aortic blood flow (by esophageal Doppler ultrasonography), systemic blood pressure, tidal volumes (by respirometry), and inspiratory pressures in the v...
متن کاملHyperinflation: control of functional residual lung capacity.
Hyperinflation is the consequence of a dysbalance of static forces (determining the relaxation volume) and/or of the dynamic components. The relaxation volume is determined by an equilibrium between the elastic recoil of the lungs and of the chest walls. The dynamic components include the pattern of breathing, upper airway resistance and postinspiratory activity of inspiratory muscles. The resp...
