These efects can retrogradely impact the systemic venous system and anterogradely afect cardiac out-put, thereby influencing systemic oxygen transport. An increase in intrathoracic …

Sep 10, 2016 · This shifts the venous return curve to the right and increases cardiac output through the Starling mechanism (lower left). This effect is identical to giving volume to expand …

Oct 13, 1999 · Finally, intracranial pressure may also be increased due to the decrease in cerebral venous return and increased venous pressure. The magnitude of this syndrome and …

Jun 24, 2010 · Besides affecting left ventricular afterload, the pleural pressure inhibits venous return, which should increase PPV. A complicating factor, however, is that pleural pressure …

Three primary mechanisms have been proposed to explain lung-kidney crosstalk during MV: gas exchange abnormalities, such as hypoxemia and hypercapnia; remote biotrauma; and …

Mar 7, 2005 · High intrathoracic pressures during lung recruitment and defining optimal PEEP may cause haemodynamic instability due decreased venous return [1]. The aim of this study …

Oct 18, 2005 · Determinants of venous return n steady state, cardiac output must equal the return of blood to the heart. This in turn is determined by the echanical characteristics of the circuit, …

Aug 26, 2024 · PEEP can adversely affect hemodynamics by decreasing the gradient for venous return, increasing pulmonary vascular resistance, and decreasing cardiac output [15] (Fig. 1). …

Jan 23, 2012 · In a recent issue of Critical Care, Bojan and colleagues [1] reported their experience with early initiation of high-frequency oscillatory ventilation (HFOV) in pediatric …

The 5% and 20% albumin programs were more effective in filling the vascular system, as evidenced by higher mean circulatory filling pressure and unchanged or decreased PPV over …
