Cardiovascular The cardiovascular system is consists of the heart and network of arteries‚ veins‚ and capillaries that transport blood throughout the body. There are two primary circulatory loops in the human body: the pulmonary circulation loop and the systemic circulation loop. The heart is a muscular organ about the size of a closed fist that functions as the body’s circulatory pump. It takes in deoxygenated blood through the veins and delivers it to the lungs for oxygenation before pumping it

and record the effects that exercise has on cardiovascular functions such as mean blood pressure‚ cardiac output‚ and total peripheral resistance by comparing each numerical function’s numerical data before and after exercise. Before exercise‚ the mean blood pressure (MPB) was 84.03 mmHg with a standard deviation of 10.3. After exercise‚ MBP was 92.19 with a standard deviation of 10.5. The cardiac output (CO) before exercise was 5.45 Liters/minute with a standard deviation of 0.98. After exercise‚ CO

Physical examinations demonstrate S3 gallop. Cardiomegaly is present and cardiac output is decreased (evidenced by Echo result “mildly enlarged left atrium‚ ejection fraction 35%”). Other evidence includes a history of coronary artery disease and hypertension. (Brashers‚ 2012b). Diastolic heart failure is also

The purpose of this lab was to determine how different conditions could affect one’s heart rate. In the life of a human‚ the heart beats approximately forty-five million times per year varying based off of factors like age‚ gender‚ physical activity level (1). Furthermore‚ throughout the course of a day‚ the heart can vary in its heart rate from a number of different environmental changes such as prolonged standing‚ altered breathing (inhale vs. exhale)‚ and jolts of excitement such as being startled

Therefore observe for‚ document‚ and communicate early indicators of patient decline‚ including decreasing blood pressure‚ increasing heart rate‚ decreased respirations‚ and changes in mental status. 2 Differentiate assessment findings that only require documentation versus those findings that need to be relayed to the health care team (i.e. normal findings). Anything abnormal needs to be reported

Considering the process of congestive heart failure‚ explain the symptoms she is having: right sided heart failure results in inadequate right ventricle output and systemic venous congestion (peripheral edema). Fatigue and weakness will occur with right-sided failure. The low BP and high P are results from a decreased cardiac output‚ which results from the heart’s inability

Describe the pathological progression of left ventricular failure. Note: continue through both sides of the heart. Include forward failure and backward failure in your discussion Heart failure is a state of circulatory congestion that results from any kind of myocardial dysfunction. It is most commonly seen in the left ventricle but can lead to right ventricular failure‚ a condition called biventricular failure. A large myocardial infarction can generally lead to ventricular failure.
