Cardiac surgery

I. Introduction A. CPR is an emergency procedure that is performed when a person’s heart has stopped beating due to sudden cardiac arrest. Cardiopulmonary resuscitation uses chest compressions and breathing to try to mimic and restore your heart’s natural rhythm. B. Introduction to Four Main Topics 1. First, I will discuss a brief history of CPR. 2. Second, I will discuss the steps to perform CPR. 3. Third, I will share some statistics on CPR. 4. And fourth, I will discuss on where…

Maximum contractile force production dependant on muscle and sarcomere length in isolated sartorius muscle of Rhinella marina Abstract: An isolated Sartorius muscle of Rhinella marina was repeatability stimulated with electrical impulses to induce isometric contraction. Contractile forces evoked were measured with a force transducer and the relationship between force and muscle length was investigated through the modulation of sample lengths from 80%-140% of the sample resting length. The data…

Specific Purpose: To demonstrate and inform the audience how to properly conduct CPR on an infant. Thesis: I would like to make this occasion a subject of much interest in saving a life, it’s about learning to conduct CPR on an infant correctly. Introduction: Conducting CPR is an important technique. Performing simple procedures and following some specific guidelines, you may save lives if a basic treatment is administered until professional medical help arrives. Attention grabber – As a…

A study was conducted to determine how well surgical teams, across 16 major medical centers, were able to carry out a new, less invasive, cardiac surgery procedure. The procedure was originally introduced in hospitals in the late 1990s, has a shorter recovery time than the conventional method, and allows for a competitive advantage for the hospitals that use it (Edmondson, Bohmer, & Pisano, 2001, p. 126). The conventional open heart operation that the surgical teams use last anywhere from two…

Occurring mostly in males, Duchenne Muscular Dystrophy is an X-linked disorder that includes progressive muscle weakening caused by an insufficient gene for the production of a protein in the muscles called dystrophin. (Lucas-Heron, 1995) It affects about one in 3600-6000 live male births, making it the most common form of muscular dystrophy. Symptoms are most often noticeable by the time patients reach the age of three to five. The affected males will lose their ability to walk by eight to…

AIM: Sarcopenia has been defined as an involuntary loss of skeletal muscle mass and strength and/or function. The presence of sarcopenia in patients with Parkinson’s disease (PD) may have prognostic effects and may be mistaken for poor therapeutic control of PD. We aimed to evaluate sarcopenia in patients with PD. METHODS: One hundred non-demented PD patients, and 95 healthy subjects were included in the study. Avarage-Muscle mass, weight, bone mass, fat mass, basal metabolism rate (BMR), body…

Cardiac Arrhythmia is an anomaly in the Heart which can be diagnosed with the help of Electrocardiogram (ECG) signal. ECG signal is a diagrammatic representation of the cardiac signal, which is most important biomedical signal, taken for the feature extraction. Since it is very difficult to analyse the ECG signal due to the size, noise and changes in the signal, automatic system for ECG signal processing is essential. For this, ECG signal is processed using wavelets based signal processing,…

Out-of-hospital cardiac arrest or OHCA is an abrupt loss of cardiac function in a public setting, usually occurring instantly or soon after symptom development (American Heart Association [AHA], 2014-a). Defibrillation and cardiopulmonary resuscitation or CPR are well-documented variables in predicting poor OHCA outcomes (Bur et al. 2001). CPR is the method of compressing a patient’s chest at 100 beats per minute, providing adequate blood flow to the body’s vital organs, preserving life (New…

Introduction Sudden cardiac death (SCD) is a world wide health problem resulting in one-fifth of unexpected deaths in the western world. Ventricular fibrillation (VF) is one of the life-threatening arrhythmias contributing to the increasing number of individuals needing urgent medical assistance (Wellens, Gorgels & Munter, 2013). The following case study will explore a complex critically ill patient who has suffered from a ventricular tachycardia (VT) and VF due to dilated left ventricle (LV)…

Endothermy has a lot of benefits and costs compared to ectotherms. Endotherms depend on their bodies metabolism to produce enough heat to raise their body temperature. Endotherms balance heat production with heat loss. Each endotherm has a range of environmental temperatures that keeps its body stable and it does this by regulating the heat loss and heat production. They regulate their body heat by vaping their metabolic rate and change its rate of heat loss by adjusting their insulation.…
