Cardiac cycle

opened his eyes, was sent to hospital, and was released a few days later. Another story includes Ralph Harms, 78, and his son Joe, and his friend Doug Green. After a great shot, he exclaimed “Yeah baby!” and collapsed right there on the course from cardiac arrest. Luckily four years ago, Joe was shown by Ralph how to do chest compressions. While Doug called 911, Joe continued, while performing CPR, Ralph’s heart started and stopped 3 times. He would not have survived and spent 3 days in a…

primarily functions as a source of power.” A muscle is also used for movement and keeping body parts in their right positions. There are 3 different types of muscles, Skeletal which is generally the muscle connected to the bone. Then there is the Cardiac which is only found in the heart, it is responsible for pumping blood through the body. Lastly there is the smooth muscle which is the type of muscle found in our internal organs, blood…

the cardiac cell. Myofibrils, a collection of individual sarcomeres, enable contraction and relaxation of the myocyte. The sarcomere is the chief contractile unit of the cell. It is made up of two main proteins, myosin (thick filament) and actin (thin filament), as well as two regulatory proteins, tropomyosin and troponin. In order for the myocyte to contract and shorten it must receive a stimulus allowing myosin and actin to interact. This stimulus comes from the depolarization of the cardiac…

are predominate for cardiac metabolic energy production meaning that these two substrates are the main energy providers when it comes to a healthy functioning heart. When a heart is healthy these two substrates are well balanced and are utilized to the fullest, but when this balance is thrown off it results in different cardiac diseases. These chronic cardiac diseases usually have one or the other substrate being utilized more. If glucose is utilized more it can lead to cardiac hypertrophy or…

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…

electrical impulses from the atria to the ventricles while slowing down the electrical signal. As a result this five the atria time to contact before the ventricles do while allowing the heart to pump blood from out of its chambers. 2. Label one cardiac cycle identifying the: P wave, QRS complex, and T wave. Explain…

Persons. They began the first attempts at dealing with sudden cardiac arrests and heart attacks. The group organized a set of rules to follow in case there was ever a situation in which a person could have drowned (History of CPR). The movement has since gained immense popularity, saving about 92,000 lives each year. In 1960, the American Heart Association started a program helping physicians become familiar with close-chest cardiac resuscitation, and now has now developed into a program…

Evaluate the anatomical and physiological similarities and differences between skeletal, cardiac, and smooth muscle. Skeletal Muscles are attached to bones. Their functions include: produce skeletal movement, maintain posture and body position, support soft tissues, guard body entrances and exits, maintain body temperature, and store nutrients. They are striated muscles because of their appearances of having bands of actin and myosin that form the sarcomere which is located in the myofibrils.…

Education but I will follow Gibbs Model of Reflection (1998) to illustrate how attending and participating in practical classes on Emergency Life Support and seminars on Teamwork were instrumental in my development. This Model contemplates a six-stage cycle. (See Appendix 1) Description A three-hour Emergency Life Support course held in a practical room on Campus on 28th October and led by a local physiologist endeavoured to provide the knowledge…

Code Blue-Where To? This is a review of the case study Code Blue-Where To?, The patient in this case is an 80 year old patient admitted to a psychiatric facility, who ultimately dies. His death is not the fault of the medical staff, but the care he received prior to his death was plagued with system errors and communication breakdowns that could be argued as causing undue patient harm. The errors include problems with staff training, policy and procedures, outdated equipment, and failure to…
