Lung

on my brother’s life since he was diagnosed at the age of 3. Asthma is a chronic inflammatory condition of the lungs that affects the airways of its victims. It causes narrowing of the airways which then interferes with air moving in and out of the lungs. Asthma affects the bronchial tubes of the lungs, but not the air sacs. When the airway reacts, all the muscles around the lungs tighten up and prevent even more oxygen from entering in. As the body responds to the stress,…

Powerlab 4 Questions When taking our subject’s different capacities, we found that her inspiratory capacity (IC) was 5.58 L, vital capacity (VC) was 5.85 L, functional residual capacity (FRC) was 1.74 L, and her total lung capacity (TLC) was 7.32 L. When comparing these numbers to the averages for a woman’s capacity we find that: her IC was more than double of that of an average woman (5.58 L compared to 2.4 L); her vital capacity was greater than average as well (5.85 compared to 3.1 L).…

Introduction Heart and lung work hand to hand daily, nonstop until we die. Some people may have experienced heart surgery because of many reasons. Some reasons for cardiac surgery is tumor, heart attack, blood clot in the heart, etc. After the surgery, there is a recovery process and the heart may not even fully heal for some patients. Since the heart may not be able to work optimally, respiration system of the patients may also be affected (Westerdahl et al, 2016). The surgery process itself…

Emphysema is a chronic lung disease, which damages the air sacs called alveoli by causing shortness of breath (dyspnea) due to the enlargement of lung sacs. Emphysema is also known as Chronic Obstructive Pulmonary Disease (Ontario Lung Association,2015). Emphysema is a disease, which not only destroys the lung air sacs but it also reduces the amount of oxygen that can reach the bloodstream. Smoking is one of the main reasons for the cause of emphysema. Therefore, it occurs mostly to the people…

syndrome. initially hyperventilation causes hypocapnia and respiratory alkalosis. as the disease progresses, arterial oxygenation begins to worsen to hypoxic levels, becoming resistant to patient becomes acidotic. compliance begins to worsen as the lungs become stiffer . crackles and rhonchi become more apparent during the acute stage of the disease. Meconium is dark-green fecal…

Chronic inflammation in the airways limits the amount of airflow to the lungs. It is progressive and relates to abnormal inflammatory response in the lungs that affects gas exchange. “This is caused by loss of elastic recoil and airflow obstruction caused by mucosal hypersecretion, mucosal edema, and bronchospasm”. One of the two Chronic Obstructive Pulmonary Disease (COPD) is chronic bronchitis. It is caused when the bronchi and bronchioles become inflamed by exposure to smoke or environmental…

Individuals with Chronic Obstructive Pulmonary Disease, or COPD live that on a daily basis. COPD is a progressive disease that gets worse over time, effecting the lungs of the patients suffering from it making very difficult to breathe. Smoking is the leading cause in patients who have COPD however, an exposure over a long period of time to lung irritants has been known to cause this disease. COPD can be broken down into two specific conditions, emphysema and chronic bronchitis. Chronic…

A pneumothorax is when air is present in the pleural space which results in a partial or complete collapse of a lung (Crimlisk, 2010). There are three classifications of a pneumothorax which include open, closed, and tension. An open pneumothorax occurs when an opening in the chest wall allows air to enter into the pleural space which occurs from chest traumas like stabbings and gun shots, or surgical thoracotomies (Crimlisk, 2010). A closed pneumothorax is when air accumulates in the pleural…

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…

leading to a compromised defense for the lungs. Since the lungs have a compromised defense, they are more prone to infection. COPD exacerbations are linked to lung infections. Emphysema is the second phenotype of COPD and affects the tissues differently than chronic bronchitis. In emphysema there is a permanent change in lung tissue. The gas exchange airways are enlarged and the alveoli are destroyed. The airways are not narrowed, rather the elastic recoil of the lungs leads to limited airflow.…
