Congestive Heart Failure
Congestive heart failure is heart disorder which occurs when the heart displays inability to sufficiently pump blood flows within the body in order to support various body demands. Congestive heart failure is characterized with a number of symptoms which include short breath, swellings of the victims legs as well as the inability to do physical exercises. Essentially, this condition is diagnosed through a physical examination of the patient, which often involves implementation of echocardiography. Furthermore, the test of blood is an ultimate process for determining the cause of the ailment. In the event of discovery of CHF, the subsequent treatment basically depends on the extent or severity, as well as the identified cause of the disorder. However, in case if a patient is in a stable condition, treatment often consists of lifestyle limits. This may include cessation of smoking, effective physical exercises as well as change in dietary habits, and sometimes direct medication. In fact, the main causes of congestive heart failure include myocardial infarctions besides other heart ailments, such as hypertension and cardiomyopathy. However, ischemic heart infections are credited as the major causes of heart infections.
Congestive heart failure develops when the muscles of the heart are unable to pump sufficient blood in order to fulfill the most important body functions. Consequently, the body lacks oxygen while the blood backs up in veins and lungs, causing other negative changes that lead to further weakening of the heart. Congestive heart failure is often caused by the malfunctioning of lower left chamber of the heart. This chamber is responsible for pumping away about 55 percent of the blood filling it per single heart beat. In the event of congestive heart failure, the left chamber pumps less than 40 percent of blood only out of it following a single heartbeat. Therefore, there is a significantly large amount of blood which is retained within the chamber due to incomplete pumping action. Furthermore, this implies that the proportion of blood coming from the lungs is also constrained following every subsequent heartbeat.
Additionally, the above process may also lead to blood backup within both the lungs and the heart. Following the malfunctioning of the left chamber, the right chamber functions may be derailed. This may lead to dysfunction of lower right chamber and therefore, a backup of blood in the body. Besides hearts poor pumping, the resultant effect is the intervention of the patients endocrine system to alleviate the situation. In particular, the condition of insufficient blood circulation may raise blood pressures, retain high proportion of both salts and water while at the same time accelerating the heartbeats. Initially, such endocrine intervention may help remedy the situation, but in a subsequent process, the heart is unable to cope with it, and the condition worsens.
The respiratory therapist detects a condition of congestive heart failure through a series of clinical checks. In particular, the diagnostic procedures are sufficiently directed by the physician assigned to the patients. For instance, this is done through a Pulmonary Function Testing (PFT) which seeks to identify the amount of air that lungs can adequately handle at a time besides analyzing the speed of air to and from the lungs. Such analysis identifies the congestive heart failure associated with tampering with oxygen intake through minimized pumping action and retention of significantly large proportion of blood in the lungs, which in turn defines a state of imbalance. On the other hand, respiratory therapists may also undertake Arterial Blood Gas test in order to determine the quantity of both oxygen and carbon dioxide gases as well as blood acidity. This process is important in detecting congestive heart failure arising from derailed blood flow which increases the absorption of various waste components by the blood due to stagnancy of the limited flow of blood.
Following the detection of congestive heart failure, the respiratory therapist also embarks on patients medication with a view to carry out full treatment of the disorder. The prospective medication often involves the use of various medicines which have specific functions in alleviating and subsequently treating the disorder. Among the major drugs used, there are angiotensin-converting enzyme (ACE) inhibitors; aldosterone antagonists and beta blockers. ACE inhibitors are responsible for the lowering of blood pressures which could occur as a result of the endocrine system intervention. Subsequently, the reduction in blood pressure also results in reduced workload of the heart. On the other hand, aldosterone antagonist is often used to treat severe attacks of congestive heart failure. As such, the drug helps improve working condition of the heart, leads to reversed scarring of heart, and prolongs life of the patient. Beta blockers also slow down the heart rate, lower blood pressure and deter risks attributable to abnormal heart rhythm. Other medication may involve the use of diuretics which basically prevent collection of fluids in the body as well as reduce the amount of fluid in the lungs, which further improves the rates of breathing.
Finally, the medication procedures for congestive heart failure depend on the severity of the disorder after its detection. However, the general procedure involves the correction of fast rhythm of the heart. This is then followed by an opening of blocked arteries or therapeutic repair or replacement of diseased valves. At times, congestive heart failure may also aggravate the underlying heart disorder. Subsequent medication may involve the use of support gadgets, such as Ventricular Assist Device (VAD). VAD can be attached to the patients abdomen and to assist in blood pumping. In some instances, the mechanical heart pump may be used as a temporary bridge to heart transplantation while in other situations, it may be taken as a permanent therapy for non-transplant candidates. However, more often, respiratory therapists encourage lifestyle changes solutions as a therapeutic approach to treating the problem. Their recommendations may include limiting both alcohol and caffeine intake, reducing fat and sodium consumption, as well as doing physical exercises aimed at health improvement.
