Respiratory tract

One of the main functions of the equine respiratory system is to trap debris. The horses nasal cavity is lined with ciliated epithelium, which produces mucus and is equipped with cilia.1 Air-borne debris gets trapped in the sticky mucus as it enters the nasal cavity and the cilia move from side to side in order to move the mucus toward the throat.1 When the debris-filled mucus reaches the throat, it can then be swallowed and digested or expelled through coughing.1 Research has shown that nearly…

residual capacity and a liquid ventilator is used to generate tidal breathing with perfluorocarbon. During partial liquid ventilation, perfluorocarbon fluids are administered into the lungs to act as artificial surfactant for complications, like respiratory distress syndrome, or as a medium for other types of pulmonary dysfunction…

The respiratory system is a system that deals with how animals receive their oxygen, and not so surprisingly there are many ways different ways animals do this. Humans have an organ called the lungs which helps us inhale oxygen, but fish do not. Fish usually use gills to breathe but there are some exceptions such as the lungfish. The lungfish is one of the only types of fish that have lungs. This is why today we will compare the differences between the lungfish and human respiratory systems. We…

Many different items can be the cause of someone choking. When a person, adult or child, is choking they lose all oxygen going to the brain. When they lose all oxygen to their brain, someone needs to administer first aid as soon as possible to decrease chances of any permeant damage. The item for adults that usually causes choking is often food, but in children it is often a small object. Although there is a universal sign for choking, a victim may not always use it. If they do not have…

as large as a tennis court is exposed to a volume of air and contaminants that would fill a swimming pool1. Inhaled particulates pass through the nasal cavity where it encounters several different obstacles. As particles move deeper into the respiratory system, inhaled particles that transverse these barriers continually are filtered down to a size of 1-5 micrometers. The nasal cavity begins the filtration process. It contains physical barriers that can filter particles down to 15 mircons. The…

Asthma is the most important respiratory disease in Canada. Each year, the number of asthma sufferers increases. Today, nearly 2.5 million Canadians suffer from asthma. In Quebec, it is estimated that over 600 000 people affected, more than 350,000 children and adolescents. Each year, the country, the direct and indirect costs of asthma over a billion dollars. Thus, the disease causes approximately 70,000 emergency room visits, hospitalizations and 4000, unfortunately, between 150 and 300…

Interrelation between the cardiovascular system and the respiratory system The cardiovascular system and the respiratory system can interrelate to perform a function such as exercise. In order for the body to move our muscles require oxygen. While the body’s muscles are working there is a constant delivery of oxygen to the muscles. The oxygen is taken to the muscles during exercise as a result of the circulatory and respiratory systems working together. The heart, blood and the lungs are the…

Non-Emergency Patient Transport (NEPT) evolved from an identified need in the Victorian health care system in the late 1990’s when there was a major reform of the (then) Metropolitan Ambulance Service. The main reason for the reform was that many patients were being delayed in their appointments, as ambulances were being redirected to emergency cases. During the early years of the new century, many lobbied for change, as the service was unregulated. In October 2003 the State Parliament passed…

Respiratory rate 20 non-labored, producing a white material on the buccal mucosa; which does not wipe off with tongue blade. Other vital signs: temperature: 101.F, pulse: 100 BMP (regular), blood Pressure: 130/72mmHg, pulse oximeter: SAO 98% RA. Auscultation…

decreases progressively from wholly aquatic, to intertidal, to land species; and is greater in young crabs than in older crabs. Often the gills are enclosed in protective chambers, and ventilation is provided by specialized appendages that create the respiratory current. As in cephalopod mollusks, oxygen utilization is relatively high—up to 70 percent of the oxygen is extracted from the water passing over the gills in the European crayfish Astacus. A decrease in the partial pressure of oxygen in…
