Pericardial fluid. A transverse section of the thorax, showing the contents of the middle and the posterior mediastinum. The pleural and pericardial cavities are exaggerated since normally there is no space between parietal and visceral pleura and between pericardium and heart. Pericardial fluid is the serous fluid secreted by the serous layer ...
The "swinging" heart. A pericardial effusion is an abnormal accumulation of fluid in the pericardial cavity. The pericardium is a two-part membrane surrounding the heart: the outer fibrous connective membrane and an inner two-layered serous membrane. The two layers of the serous membrane enclose the pericardial cavity (the potential space ...
2 per 10,000 per year (US) [ 3 ] Cardiac tamponade, also known as pericardial tamponade (/ ˌtæm.pəˈneɪd / [ 4 ]), is a compression of the heart due to pericardial effusion (the build-up of pericardial fluid in the sac around the heart). [ 2 ] Onset may be rapid or gradual. [ 2 ] Symptoms typically include those of obstructive shock ...
The pericardium is a fibrous sac surrounding the heart composed of two layers: an inner visceral pericardium and an outer parietal pericardium. [1] The area between these two layers is known as the pericardial space and normally contains 15 to 50 mL of serous fluid. [2] This fluid protects the heart by serving as a shock absorber and provides ...
This examines for free fluid around the kidney and spleen. Pelvic views (Long and transverse axis). The suprapubic view helps assess for free fluid in the pelvic cavity. Cardiac view. The pericardial component is assessed using the subxiphoid view. Lung views (Right and Left, Long axis). These final views help determine if a pneumothorax is ...
Pericardium. Walls of the heart, showing pericardium at right. The pericardium (pl.: pericardia), also called pericardial sac, is a double-walled sac containing the heart and the roots of the great vessels. [1] It has two layers, an outer layer made of strong inelastic connective tissue (fibrous pericardium), and an inner layer made of serous ...
Serous membrane fluid collects on microvilli on the outer layer and acts as a lubricant and reduces friction from muscle movement. This can be seen in the lungs, with the pleural cavity. Pericardial fluid is a serous fluid secreted by the serous layer of the pericardium into the pericardial cavity. The pericardium consists of two layers, an ...
Obstructive shock is one of the four types of shock, caused by a physical obstruction in the flow of blood. [1] Obstruction can occur at the level of the great vessels or the heart itself. [2] Causes include pulmonary embolism, cardiac tamponade, and tension pneumothorax. [3] These are all life-threatening.
