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, a lipoprotein complex, function by decreasing the surface tension of the fluid…

It also occurs when not enough oxygen can get from your lungs to your blood, mean it cannot be transported. Oxygen is not only needed for energy but also for other organs like the heart and brain so they can work to their best ability. However, this is not an actual disease and something which can occur when…

Croup is an acute infectious laryngotracheitis which occurs mostly in children less than six years of age(although the peak incidence is around two years). It is characterized by a barking cough, hoarse voice and respiratory difficulties, which are typically seen to occur at night. Symptoms of croup Croup usually begins as an ordinary cold with symptoms such as a runny nose, slight rise of temperature and a mild cough. Within a week, a child with croup develops a barking cough with noisy…

Silicos disease form part of the lung disorder known as pneumoconioses and is characterized by nodules and fibrous scar tissue within the lungs. It is often caused by inhaling silica particles from the quartz in rocks, sand and similar other substances. These particles gets entrapped in the alveoli and macrophages that are present in the alveoli consumes the silica particles and died with the resulting inflammation attracting more macrophages, resulting into the formation of nodules and fibrous…

Chronic diseases of respiratory system are the fourth leading cause of death in the United States. They affect airways and lung function, one common obstructive lung disease is asthma. According to CDC.gov about 17.8 million adults and 6.8 million children are suffering from asthma [9]. According to world health organization estimates, 235 million people suffer from asthma worldwide [10]. Asthma disease doesn’t have obvious symptoms which makes it hard to diagnose, so major component of chronic…

Introduction Acute bronchospasm caused by asthma is also referred to as an asthma attack. Bronchospasm means your air passages become narrowed. The narrowing is caused by inflammation and tightening of the muscles in the air tubes (bronchi) in your lungs. This can make it hard to breathe and cause you to cough or breathe loudly (wheeze). What are the causes? Possible triggers include: Animal dander from the skin, hair, or feathers of animals. Dust mites contained in house dust. Cockroaches.…

For many years, open-heart surgery has been the sole option when it comes to valvereplacements in the heart. Today, with the help of fluoroscopy, a non-surgical approach has beenevolving and is changing the face of medicine. Transcatheter Valve Replacement (TVR), is apercutaneous technique that uses fluoroscopic guidance to replace a diseased or dysfunctionalvalve without ever having to go under the knife. To be able to intervene percutaneously is the“most exciting advancement in the treatment…

First, I would do a lung volume test. This test measures the volume of air in the lungs at distinct periods of the breathing cycle. It is accomplished utilizing a machine called the plethysmography. You are seated during the exam and will be asked to breathe in and out of a mouthpiece and sometimes to gasp for air (Ranu et al., 2011). The exam is specifically beneficial in distinguishing between restrictive lung diseases such as pulmonary fibrosis and obstructive lung diseases such as asthma.…

Cystic fibrosis is a genetic disorder that affects many organs and impairs the lung function. A blocked chloride transport in the cell membranes creates mucous that has little water content and becomes thick. The thick, sticky mucous causes problems in the lung, pancreas, liver, salivary glands, and testes. It is an autosomal recessive trait and the cystic fibrosis gene can be located in chromosome seven. A symptom of cystic fibrosis is very salty-tasting skin and the reason is, is when a…

Asthma affects the body through bronchospasms; these are unusual narrowing or constrictions of the airways. These are usually caused a spasm in the smooth muscles of bronchi and bronchioles, an inflammation of the airways or an excessive production of mucus due to an allergic reaction or possible irritation. This therefore makes it difficult to breath and as a result causes the individual to start wheezing due to the inhaled air struggling to pass through the narrowed airways…
