Treatment IVIG , theophylline , terbutaline , montelukast Capillary leak syndrome , or vascular leak syndrome , is characterized by the escape of blood plasma through capillary walls , from the blood circulatory system to surrounding tissues, muscle compartments, organs or body cavities.
The primary mechanism is likely to be high pulmonary vascular pressures with concurrent negative airway pressures, causing extreme stress across the pulmonary capillary membrane (the fragile membrane separating blood in the pulmonary capillaries from the air-filled alveoli) and consequent hemorrhage into the air spaces of the lung.
Capillary refill time (CRT) is defined as the time taken for color to return to an external capillary bed after pressure is applied to cause blanching. [3] It can be measured by holding a hand higher than heart-level and pressing the soft pad of a finger or fingernail until it turns white, then taking note of the time needed for the color to ...

Return of spontaneous circulation (ROSC) is the resumption of a sustained heart rhythm that perfuses the body after cardiac arrest. It is commonly associated with significant respiratory effort. Signs of return of spontaneous circulation include breathing, coughing, or movement and a palpable pulse or a measurable blood pressure.
Diagram of a pulmonary artery catheter in position. The pulmonary wedge pressure (PWP) (also called pulmonary arterial wedge pressure (PAWP), pulmonary capillary wedge pressure (PCWP), pulmonary artery occlusion pressure (PAOP), or cross-sectional pressure) is the pressure measured by wedging a pulmonary artery catheter with an inflated balloon into a small pulmonary arterial branch.

The aortic aneurysm is a special case where the aorta, the body's main blood vessel, becomes ruptured through an inherent weakness, although exertion, raised blood pressure or sudden movements could cause a sudden catastrophic failure. [23] This is one of the most serious medical emergencies a patient can face, as the only treatment is rapid ...
For spontaneous intracerebral hemorrhage seen on CT scan, the death rate is 34–50% by 30 days after the injury, [22] and half of the deaths occur in the first 2 days. [51] Even though the majority of deaths occur in the first few days after ICH, survivors have a long-term excess mortality rate of 27% compared to the general population. [ 52 ]
