Effect of different pressure levels on the dynamics of lung collapse and recruitment in oleic-acid-induced lung injury.

The effects of different inspiratory and expiratory airway pressures (Paw) on the dynamics of lung collapse and recruitment were studied in 14 anesthetized, mechanically ventilated, pigs with oleic-acid-induced lung injury. Repetitive CT scans of the same slice were obtained every 0.8 s during different inspiration and expiration hold procedures.

The patient with left heart assist device: nursing management.

When prolonged use of adjuvant therapy (positive inotropic agents, ventricular or atrial pacing), including intra-aortic balloon counter-pulsation, fails to achieve separation of patients with poor ventricular performance from CPBP the use of LHAD should be considered. The left heart assist device is a means of diverting a moderate portion of the systemic blood flow around the left ventricle. It provides hemodynamic stability until the left ventricle regains is effectiveness and capability as a pump.
