The heart is the main organ of the body and maintaining its condition is significant to your health. Over time many scientists recognized this, but they also wanted to invent a simpler way to count the number of beats per minute to identify when a heart rate was normal or abnormal. These discoveries led to various inventions still used today. An example includes inventions such as the electrocardiogram. Finally, Avicenna’s discoveries of the arterial pulse subsequently led to his discovery of heart
Electrocardiography is considered to be one of the most powerful diagnostic tools in medicine that is routinely used for the assessment of the functionality of the heart. An ECG is the conventional method for noninvasive interpretation of the electrical activity of the heart in real-time. The electrical cardiac signals are recorded by an external device by attaching electrodes to the outer surface of the skin of the patient’s thorax. These currents stimulate the cardiac muscle and cause the contractions and relaxations of the heart. The electrical signals travel through the electrodes to the ECG device which records them as characteristic waves.
The operation is performed in the chest cavity on the heart, with the septum and valves being reconstructed or replaced. The cardiovascular system is affected because this determines how well the heart is able to pump blood throughout the body. The surgical pathology of the atrioventricular septal defect repair procedure abnormal anatomy. This defect, which is created during gestation pre-birth, is considered
Three activities are performed that best illustrate how the cardiovascular system works. The activities have to do with listening for heart sounds, and feeling for pulses in peripheral locations on the body, such as wrist or arm. The reason heart rate is determined is because the quality of the pulse, the regularity and strength, is usually an indicator of cardiovascular function. Blood pressure is also measured indirectly, such as with a medical instrument. The arterial blood pressure is taken because it determines the heart’s condition the health of the blood vessels.
Medical staff should have good knowledge about advanced life support before undergoing advanced drug administration, rapid sequence intubation and cardiac resuscitation. It is very important that every medical personnel [Doctor, Anesthesia, paramedics and Nurses] who are prone to emergency should have stand by everywhere and time to save life, and improve the quality of cardiac resuscitation. At least the Doctors, anesthesia, Paramedics and Nurses staff must be predetermined about the need of resuscitation, by considering risk factors like hypoxia, hypothermia, hypoglycemia, acidosis and traumas. Because frequently facing life threatening situations [Boonmak P, Boonmak S,2004]
Because AEDs are portable, they can be used by nonmedical people. They can be made part of emergency response programs that also include rapid use of 9-1-1 and prompt delivery of cardio pulmonary resuscitation (CPR). All three of these activities are vital to improving survival from cardiac arrest. The concepts I believe I learned well is the heart diseases. I like learning about diseases and investigating how to prevent it.
The receptor is the sense organ that detects the change, the control centre is usually the brain or a certain section of the brain, and the effector, which produces the response to counteract the change. An example of a homeostatic system is blood glucose regulation. This works to ensure the body is at the set point it needs to be at, ensuring that the body is working optimally. In terms of blood glucose regulation that set point is 5mM. There are different internal and external factors that can affect the amount of glucose in the blood such as exercise, diet and hydration levels.
In order to check if a patient is suffering from hypertension or abnormal levels of blood pressure, there are four indirect and non-invasive methods to assess the patient. The methods are auscultation, oscillometric, through the wrist type method or through the finger cuff method. 2. Auscultation Method Auscultation method are often used in the clinics and hospitals by the doctors manually. This method requires the observer to listen to the Korotkoff sounds produced when the blood flow is constricted.
Many lives were saved because of the defibrillation. For this great reason defibrillation plays an important rule in the medical field. Defibrillation in medical science is that method in which an electrical device sends an electric shock wave to the heart to stop an extremely fast, irregular heartbeat, and return the regular heart rhythm. In addition, this great device is performed to correct critical fibrillations of the heart, which could result in heart
The signs and symptoms of COPD include shortness of breath, chronic cough, fatigue and having bluish lips and nail beds (American Lung Association, 2014). The second vital human body system is cardiovascular system (CVS). CVS plays an integral role in enhancing and facilitating the proper function of heart in order to allow the body to function as a whole. CVS comprises of two components namely heart and blood vessels. Heart is a four-chambered muscular pumping organ that divides into atriums and ventricles that are separated by valves to prevent backflow of blood among the compartments (Smeltzer, Bare, Hinkle, & Cheever, 2010).
