Whooping Cough/ Pertussis Most Prevalent Whooping Cough is most prevalent in babies younger than 6 months old or kids that are 11-18 years old. It is most prevalent in these age groups because babies younger than 6 months don’t have the immunizations yet, and kids 11-18 immunization has started to fade. Description Whooping cough is an infection of the respiratory system caused by bacteria called Bordetella pertussis. Whooping cough causes severe, highly contagious, coughing spells, which…

Respiratory distress syndrome (RDS) commonly known as hyaline membrane syndrome occurs in many premature births. As the gestational age for a baby decreases subsequently the likelihood of them having this condition will increase because their lungs are severely underdeveloped. The problems that stem from RDS include lack of surfactant, smaller alveolar surface span, elevated compliance of the small airways, and occasionally the ductus arteriosis might be a factor if it doesn’t close shortly…

Seminars in Speech and Language, 17;32;(2), 141-149. doi:10.1055/s-0031-1277716 − The article stated incidences of hyponasality in both cleft and non-cleft populations. Common causes of hyponasality include swelling of the nasal passages secondary to allergic rhinitis or the common cold, adenoid hypertrophy, nasopharyngeal polyps, or even hypertrophic tonsils that…

Acute Respiratory Distress Syndrome (ARDS) occur when alveoli of the lungs are filled with fluids due to severe injury or illness. This fluid buildup instead of air in the alveolar air sacs causes decreased level of oxygen transfer from the lungs to the blood stream. A chest x-ray will show clinical appearance of acute pulmonary edema without elevated left atrial pressure or cardiogenic causes (Brochard, 2011). This will cause a severe deprivation of oxygen to vital organs and leads to…

airways will flare up to the simplest triggers like pollen, animal dander, dust, fumes, or poor air quality (WebMD). A second grader named Hannah Austin from Smyrna, Georgia suffers from asthma. Twice a day she has to exhale all the air from her lungs to take a puff of a low- dose steroid. She often has to struggle to catch her breath when the air quality is poor (Fortin). According to the Atlantic each state department of education makes is own length of school day, but has to fulfill the 180…

The toxin was first discovered in 1735 Europe as it caused a fatal disease of the nervous system. Its cause was suspected to be connected to German Sausages. This is originally where its name came from, as due to these suspicions the toxin was named “botulus” – the Latin for sausage. Since then we know that Botulinum Toxin is a potent neurotoxin that is produced by rod-shaped spore-forming anaerobic bacterium called Clostridium bacterium. The bacterium require special conditions to reproduce;…

According to the Centers for Disease Control and Prevention, asthma is a disease that affects your lungs. It causes repeated episodes of wheezing, breathlessness, chest tightness, and nighttime or early morning coughing. This chronic condition is when the airways that carry air to and from lungs get affected. People that are affected with this for a long time are said to be asthmatic (CDC.GOV, 2015). The inside walls of an asthmatic's airways are swollen or inflamed. This swelling or…

should read through your lecture notes on the respiratory system; the background information for this class on Moodle; and section 23-7 in Martini (2012) p830-838. Please hand your individual work into the Student Centre by the deadline. Exercise 1: Lung Volumes and Capacities The predicted values are based on the Goldman and Becklake equations for Pulmonary Function (cited from the John Hopkins Pulmonary Laboratory). 1. Comment on the differences between the experimental and…

the lungs. Located on the inner walls of the trachea are small hairs, these hairs catch dust and other contaminants from inhaling, generally through the oral cavity due to its lack of filtration, collected contaminates are later disposed of via coughing. Gas Exchange Lungs: • Bronchi- At the end of the trachea two tubes stem off of its base, each connected to a lung. The bronchi’s connection to the lungs allows air from external respiratory intakes/openings to pass, efficiently, into the lungs.…
