Arterial thromboembolism in systemic circulatory system

Haemodynamic changes due to systemic arterial shunts in a destroyed lung mimicking pulmonary thromboembolism on CT.

BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/bcr-2015211746 DESCRIPTION A 51-year-old woman presented to our department with multiple episodes of massive haemoptysis. She had a history of pulmonary tuberculosis. High-resolution CT scan showed a completely destroyed right lung with fibrocavitatory changes (f...

Systemic circulatory responses to hypocapnia in man.

Physiol. !223(6): 1308-1312. 1972.Hypocapnic alkalosis, induced by voluntary hyperventilation in normal man, was associated with increases in cardiac output and in heart rate and decreases in mean arterial blood pressure and in systemic vascular resis...

Venous and arterial thromboembolism in severe sepsis.

The burden of thromboembolism (TE) in severe sepsis is largely unknown. We assessed the prevalence of venous and arterial TE in patients with severe sepsis over a four-week period. We performed a retrospective analysis of a pooled database of three randomized, placebo-controlled trials of two novel pharmacological agents for the treatment of severe sepsis, drotrecogin alfa (activated) (DrotAA) ...

Mean arterial pressure nonlinearity in an elastic circulatory system subjected to different hematocrits.

The level of hematocrit (Hct) is known to affect mean arterial pressure (MAP) by influencing blood viscosity. In the healthy population, an increase in Hct (and corresponding increase in viscosity) tends to raise MAP. However, data from a clinical study of type 2 diabetic patients indicate that this relationship is not universal. Instead, individuals in the lower levels of Hct range display a d...
