Hypoxia

The lay people associate Dementia with memory loss, but it’s just not that simple. Dementia is a gradual disease with many other characteristics, such as, loss of attention, orientation, language, judgement, and reasoning (Lewis, Dirksen, Heitkemper, Bucher, & Harding ). “Personality changes and behavioral problems such as agitation, delusions, and hallucinations may occur” (Lewis, Dirksen, Heitkemper, Bucher, & Harding). All of the issues that come with Dementia affect the entire person’s…

water, agricultural, nutrient, and land pollution. When looking at nutrient and water pollution there are many negative effects. Pollution can create large dead zones, or areas in water with little or no oxygen, where aquatic life cannot survive. Hypoxia is the prime reason for these dead zones where algae blooms consume oxygen as they die and decompose. These dead zones are a major issue causing entire ecosystems to collapse. There are an estimated one hundred and sixty six dead zones just in…

A Matter of Salt- Cystic Fibrosis Dating back from the Middle Ages, European Folklore warned, “woe is the child who tastes salty from a kiss on the brow, for he is cursed, and soon must die”. These children were considered hexed, with death in childhood being common. Though the cause was unknown at the time, this warning referenced children born with cystic fibrosis. Cystic fibrosis is a disease caused by a gene mutation, changing a protein that regulates the movement of salt in and out of…

INTRO Polycythemia Vera (PV) is a slow growing blood cancer that causes the bone marrow to over produce blood cells. It is a chronic progressive Myeloproliferative Neoplasm (MPN) primarily characterized by an elevation of red blood cells ("Polycythemia Vera (PV)," 2014). SIGNS AND SYMPTOMS Most people with PV don’t experience symptoms, but those who do will undergo headache, weakness, excessive sweating, painful swelling of one joint (often the big toe), difficulty breathing when you lie down,…

Normal pH within the blood can range between 7.35 and 7.45 arterial and venous is 7.32 thru 7.42. Normal HCO3 for arterial is 22 thru 26 mEq/liter and venous is 19 to 25 mEq/liter with PCO2 normal for arterial 35 thru 45 mm Hg and venous 38 thru 52 mm Hg. Normal PO2 is 80 to 100mm Hg for arterial and venous is 28 thru 48 mm Hg. Acidosis can affect the central nervous system within the body and left untreated can lead to death. Alkalosis affects the central nervous system which can cause muscle…

I am a strong believer that life is a gift and it is the greatest teacher to oneself and nothing can be a better way to use it productively than the path of science. My journey started from all the way from undergraduate has been a mixture of learning from various interdisciplinary fields. The skills of experimenting and practice are the two elements of my faith which built the foundations of what I still cherish are the long hours in the laboratory of my mentor Professor P Rajeswara Rao. The…

bloater) 3. This type of COPD is known to have "frequent episodes of right heart failure, and produces copious sputum resulting in coughing and respiratory infections." 4. Blue bloaters suffer from "pulmonary hypoxic vasoconstriction from the marked hypoxia and respiratory acidosis." 5. This leads to "right ventricular hypertrophy and cor pulmonale. The right heart failure then leads to "systemic venous congestion, peripheral edema, hepatic congestion, and ascites."…

Introduction/Background Pulse oximetry (PO) is the one of most commonly used non-invasive medical device that evaluates the patient’s oxygen saturation in the peripheral arteries (SpO2). Thus, it alerts healthcare professionals and allow early detection of hypoxaemia in patients that requires prompt treatment. PO has become an essential tool that widely used in monitoring patients’ clinical conditions in intensive care, perioperative care, emergency care, acute and sub-acute healthcare…

Introduction The most common cause of death in infants up to a year old is sudden infant death syndrome (Meadows-Oliver & Hendrie, 2013). Sudden infant death syndrome (SIDS) is the unexpected death of an infant from one month to twelve months of age that cannot be explained even after a thorough investigation (Schnitzer, Covington & Dykstra, 2012). Although the death cannot always be explained, most SIDS cases are believed to be a result of accidental suffocation. Common causes include…
