1. What does the PR interval on the ECG represent? What is the normal value? The P-R interval is the interval between the beginning of electrical excitation of the atria and the beginning of excitation of the ventricles and its normal value is 0.12- 0.20 seconds. 2. What does the QRS complex on the ECG represent? What is implicit in the information that the QRS complexes on Mr. Ortega’s ECG had a normal configuration? The QRS complex is the most important in the EKG since its represents…

evaporates readily at room temperature or a liquid that has a measurable vapor pressure. Vapor pressure is the equilibrium pressure resulting in the evaporation of a liquid in a closed container.1 It is important to know the vapor pressure of a volatile liquid because the higher the vapor pressure, the faster the liquid evaporates.2 So…

1. Briefly describe a situation that occurred this week that made you feel challenged. A situation that made me feel challenged was today’s simulation. Even though, this is not the first time I’ve done a simulation I feel that I could’ve have done a lot better. The patient was a 67-year-old male who was hospitalized for exacerbation of COPD. When we went into the room, we found the patient on the floor with visible cyanosis. 2. How did you manage the situation? What resources did you use to…

Elevated intracranial pressure (ICP) is a common and potentially life threatening condition arising from a variety of pathological conditions including traumatic brain injury (TBI), intracranial hemorrhage, disturbance of cerebral spinal fluid (CSF) circulation and brain tumors. Although ventriculostomy continues to be the gold standard modality, the potential risks of misplacement, infection, hemorrhage and obstruction have led to development and implementation of alternative intracranial…

Pseudophakic cystoid macular edema (PCME), also called Irvine-Gass syndrome, was identified and described for the first time by Irvine-Gass in the 20th century.1 Although the occurrence of PCME has declined with the use of modern surgical techniques, it is still recognized as one of the most common causes of poor visual outcome following cataract surgery.2 The pathogenetic mechanism underlying this syndrome remains unclear, although several factors have been identified potentially capable of…

INTRODUCTION The aim of this review is to employ relevant primary literature resources to discuss the potentials of multidisciplinary cardiopulmonary care teams in cardiovascular life support and resuscitation towards patient mortality reduction and achievement of positive neurological outcomes after a cardiopulmonary arrest. Cardiovascular disease is the leading cause of more than 17.3 million annual deaths, representing 31% of global mortality rate, with nearly 801000 American deaths…

Embase, Psychinfo, Cochrane Library, AMED, and CINAHL. The average salt intake recommendation is around 5-6 grams, but most Americans exceed 6 grams of salt on a daily basis. This has resulted in a correlation between high salt intake and high blood pressure, leading to cardiovascular diseases. Suggestions have been made about…

Introduction Heart failure (HF) is a growing epidemic today as people are living longer with the diagnosis. In 2013, it was estimated that over 550,000 new cases of HF arise annually in the United States.1 Globally, the prevalence of HF is over 23 million.1 The American Heart Association defines heart failure as a syndrome resulting from “any structural or functional cardiac disorder that impairs the ability of the ventricle to fill or eject blood.” 1 In essence, the heart fails to meet the…

Introduction / 5p- 1200w The most frequent cause of sudden cardiac death is hypertrophic cardiomyopathy (HCM), mainly in young people. It is characterized by thickening in the left ventricle (LV) wall not related to load condition such as aortic stenosis or systemic hypertension (Bing, Knott et al. 2000). It is estimated that approximately one in 500-1000 population. HCM is a complex genetic inherited cardiovascular disease caused by dominate mutation in coding of cardiac sarcomere proteins gene…
