Acute toxicity

CLINICAL CLARIFICATION • Acute respiratory distress syndrome {ARDS) is a condition of dysfunctional gas exchange {i.e., pulmonary interstitial and alveolar edema progressing to advanced fibrosis) that is characterized by acute onset, bilateral pulmonary infiltrates, severe hypoxia, the absence of evidence of left atrial hypertension, and a significant risk of mortality.25 DIAGNOSIS CLINICAL PRESENTATION • History o The patient may be in present with complaints of acute dyspnea and suffocation…

There are many diseases out there that effect the lungs, and can be life-threatening. They affect millions of people every year. Some examples would be lung cancer and acute respiratory distress syndrome. Cancer is a disease that, among other things, effects the communication between cells. Acute respiratory distress syndrome prevents oxygen from getting into the blood. With so many people being at risk, it can lead some people to wonder why the cure hasn’t already been created. There are many…

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…

the problem when he discovered that few people in the airline industry were actively working on ways to improve the quality of airplane air” (Brown). During flight, many pathogens come on board with the passengers such as: Influenza, Sars (Severe Acute Respiratory Syndrome), Tuberculosis, H1N1(Swine Flu), Meningococcal disease, and Ebola. “Wang referenced two cases of these viruses spreading on a plane, with the H1N1 flu virus spreading it to 17 other travelers and Sars spreading to 22…

Review Article Treatment of Respiratory Distress Syndrome in Preterm Infants: A Review Keishera Aldonza Candidate for Bachelor, Department of Medical Laboratory Sciences at University of Massachusetts Dartmouth Introduction Preterm infants often display signs of respiratory distress syndrome at birth due to the immaturity of the lung structure, with respiratory morbidity decreasing as gestational age increases. Respiratory distress syndrome is caused by a deficiency of surfactants. Surfactants…

Acute Respiratory Distress Syndrome The patient in this case study had an onset of acute respiratory distress syndrome brought on by trauma. Acute respiratory distress syndrome (ARDS) is a disease state characterized by fluid buildup in the alveoli, making it difficult to oxygenate (MedlinePlus.gov). It is a life-threatening lung condition. The new definition and severity of ARDS are defined as PaO2/ FiO2 with a PEEP of 5+ (200-200) = mild, (100-200) = moderate, (<100) = severe…

Abstract This paper investigates the origins, human-to-human transmission and the physiological changes in humans due to the Middle East Respiratory Syndrome Coronavirus (MERS-CoV) and Severe Acute Respiratory Coronavirus (SARS-CoV). Research shows that these two coronaviruses are both deadly and severe their diseases are. They both have caused assorted respiratory difficulties including pneumonia, organ dysfunction, bronchitis,cough and fever, and deficiency of breath. SARS and MERS are very…

The death of an elderly man on a flight from Beijing to Brisbane has been brought to our attention, as it appears the death was the result of an infectious disease, which we believe may have been ‘severe acute respiratory syndrome’ (SARS). SARS is a respiratory illness produced by a coronavirus, called ‘SARS-associated coronavirus (SARS-CoV). It was first identified in 2002 in southern China, which resulted in an epidemic in 37 countries, with more than 8000 cases and 774 deaths. The epidemic…

Nitric oxide can be administered by a few different ways. When a patient is on a ventilator, nitric oxide is nebulized on the inspiratory cycle. Nitric oxide can also be given by a facemask or even a nasal cannula. The normal ranges for nitric oxide is 1 – 80 parts per million. High levels of nitric oxide can be very harmful and may even cause death, pulmonary edema or methemoglobinemia. A high concentration would be considered to be between 5,000 and 20,000 ppm. The length of time that…

INTRODUCTION: Toxicity test evaluates the deleterious effects of chemicals on humans, animals, plants, environment following single (acute) or repeated (long term) exposure (Arwa and Vladimir, 2016). Safety evaluation of chemicals is very important for their development and approval for human uses (Gallagher, 2003; Peers et al., 2012). In risks assessment, there is no doubt that the best test species for humans are humans since accurate extrapolation of animal data directly to humans cannot be…
