If blood flow through the lungs to the left side of the heart is reduced significantly‚ hypertension can develop. Reduced blood flow to the left side of the heart will result in reduced cardiac output because of the decreased venous return (starling law of the heart). As a result‚ blood pressure falls and the mechanism that regulate blood pressure are activated(regulation of mean arterial pressure. Manifestations of hypotension‚ such as increased heart rate‚ a weak pulse‚ and

body. Oxygenated blood is crucial to the functioning of the organs and perfusion of tissues‚ which in turn is crucial to the functioning of the body as a whole. In Lewis‚ et al‚ it traces the blood flow of the heart: The right atrium receives venous blood from the inferior and superior venae cavae and the coronary sinus. The blood then passes through the tricuspid valve into the right ventricle. With each contraction‚ the right ventricle pumps blood through the pulmonic valve into the

Blood Gas Analysis at the Core Laboratory at University Hospital‚ London‚ Ontario. Blood is one of the most important fluids in the human body. It helps carry nutrients such as oxygen to the cells in the body and transports out wastes like carbon dioxide and other metabolites from these cells. Since blood is the medium through which the different organs and tissues in our body communicates‚ keeping a close eye on the constituents of a blood sample would provide a good indication of the functioning

and Diastolic BP from 56 mmHg to 32 mmHg is observed. The mean arterial pressure(MAP) decreased from 74 to 43 mmHg. However‚ the heart rate increased from 80 to 93 bmp. This was due to the pooling of blood in the lower limbs subsequently decreasing venous return‚ thus causing stroke volume and cardiac output to fall.Therefore a decrease in the MAP was observed according to the equation: MAP = CO X TPR. After 1 minute‚ the systolic‚ diastolic BP‚ MAP increased to 105‚53‚67 mmHg respectively

NTRODUCTION Superior vena cava syndrome (SVC) was first described in the 18th century in a patient with an aortic aneurysm caused by untreated syphilis [1]. By 1954‚ there were well over 250 cases documented in the literature of which approximately 40% were due to infectious causes such as tuberculous mediastinitis and syphilitic aneurysm [2]. Advances in medicine have eradicated many of the sequelae of the above diseases; however it appears more recently that the most common cause of SVC is malignancy
