Franco, Enders, Wilson, Gajic, and Pannu (2016) conducted a retrospective study that reviewed the patterns and results of rescue techniques used in patients that suffered from severe hypoxemia. The researchers defined severe hypxemia as the failure to attain enough arterial oxygen while on oxygen or because of an injury due to the change in pressure, barotrauma. The article stated that previous studies have studied the techniques used in the rescue of the patients, however, none of the studies…

Sometimes when we ingest certain substances, we can stimulate foci (nodes that pace the heart at a certain speed) in the heart which can give us the feeling of “skipping a beat.” The feeling of “skipping a beat” is actually another beat that follows the original beat quickly which gives us that feeling. A lot of factors can stimulate other foci such as atrial and junctional in our heart. These factors, according to Dr. Dubin, includes adrenaline (epinephrine) released by adrenal glands,…

What is the cardiovascular system? The cardiovascular system functions when it transports oxygen from the lungs to the tissues around the body. While also transporting oxygen around the body this system transports carbon dioxide which is a waste product from the body to the lungs. The cardiovascular system works when a person breathes air through their mouth and nose and then it travels the lungs. Oxygen from the air is slowly absorbed into the bloodstream through the lungs. The heart then…

Primary prevention is defined as preventing the onset of disease through interventions that are applied before there is any evidence of disease or injury. Examples of such prevention include things like vaccination. By this definition, a primary preventative strategy for this patient would be recognising that he had several risk factors for his stroke and aiming to prevent the stroke before it happened. He is beyond that stage now but if he was given an intervention before his first stroke in…

In 1967 Dr. Tomisaku Kawasaki, a Japanese Pediatrician was the first to describe a serious illness characterized by inflammation of blood vessels throughout the body that primarily affects children under the age of five and infants. The Kawasaki Disease, named after Tomisaku, is also known as Kawasaki syndrome and Mucocutaneous Lymph Node Syndrome, because it affects lymph nodes, skin and the mucous membranes inside of the mouth, nose and throat. Kawasaki Disease is slightly more common in…

The development of advanced microscopes has enabled scientists to further their investigation on the criteria for life. As a result, biologists have been confronted with a baffling question: is there a size limit on life? If so, then just how small can something be before it can no longer be considered alive? Ever since the discovery of nano-sized particles called “nanobacteria” or “nanobes”, researchers have been scrambling to unravel and analyze the mysterious functions of these purported…

Alamellu had heart disease due to damage of her mitral valve that was causing severe joint pain throughout her body. When Alamellu visited a doctor that practiced western medicine, he suggested heart surgery as a form of treatment. However, Alamellu was very apprehensive about the surgery because she was…

Firefighting is known to be one of the most physically demanding jobs in the world. Any firefighter can attest to this statement and it is well known that personal health and wellness are important in the firefighting profession. Demands are placed on the body in several different facets. These include but are not limited to physical, psychological, and sometimes emotional stresses to the human body. Throughout a long firefighting career the stresses can begin to be overwhelming and start to…

with fast ventricular response and a left bundle branch block. Once this was treated and under control the patient went for an echocardiogram and the results from this were: left ventricle ejection fraction of 62%, left ventricular hypertrophy, mitral valve…

Cardiac work in the isolated heart from normal rats following acute MI Juea Park INTRODUCTION The heart is a muscular oragn which has to perform work to eject blood for the right and left entricles. Two laws govern the relationship between ventricular volume and cardiac pump performance. The first, the law of Laplace, is a low stating that when the ventricle dilates, the wall stress needed to achieve a give intraventricular pressure is increased. The second,…
