My pulse pressure was 45 (SP – DP). My mean arterial pressure was 93 (DP + 1/3 (SP – DP). 2. Mean arterial blood pressure is determined by cardiac output and total vascular resistance. The mathematical equation for mean arterial blood pressure is equal to cardiac output x total vascular resistance. The amount of blood pumped out of the heart is the cardiac output‚ and the sum of the resistance of all systemic blood vessels is equal to the total vascular resistance. An increase of blood volume‚ heart

wound to the right ventricle. Many believed this was the beginning of cardiac surgery. However‚ one of the most prominent surgeons of that time‚ Theodor Billroth‚ pronounced that "A surgeon who would attempt such an operation [cardiac suture] should lose the respect of his colleagues. There were many unsuccessful sutures that occurred‚ but Rehn accomplished the “impossible” that same year. (Principles and Practice: History of cardiac surgery and anesthesia).

There is one nucleus. The fibers are striated and branched with the single nucleus. The sizes of the fibers are quite large‚ actually. As a result of the contractions in the Human Cardiac Muscle cells‚ it keeps your heart beating. A good thing about this is‚ the tissue can be controlled involuntary

I remember the time when I used to work‚ as a cardiac monitor technician in the Intensive care unit of a local hospital in Tampa. I was watching the patient’s monitors while one of them started showing and ST elevation on the cardiac rhythm‚ (ST elevations usually on the strip can mean different things and depending on the leads showing on the screen‚ it might represent an infarct). In that case‚ the patient was experimenting a heart attack. Suddenly‚ the patient started complaining of shortness

1. Describe four important points and why they are important. Harden (2011) explains the importance of therapeutic hypothermia and the benefits of implementing this intervention post-cardiac arrest. Therapeutic hypothermia is used to potentially decrease or prevent any kind of neurologic deficit that could occur post - arrest from decreased perfusion and oxygenation to the brain. The benefits of starting this are exponential and “…decreases free radical production‚ inflammatory pathways‚ cellular

the early 1960s for restoring the circulation and respiration in a patient who has suffered cardiac arrest‚ often leading to heart attack. Lack of oxygen to the brain causes loss of consciousness‚ which then results in abnormal or absent breathing. Brain injury is likely if cardiac arrest goes untreated for more than five minutes. If there is no medical provider around to give quick medical care‚ the cardiac arrest may lead to brain injury. The only mean is to keep the blood circulating by providing
