congenital heart condition. There are actually two main characteristics: 1) The pulmonary valve, which allows the blood to flow from the heart to the lungs, is completely blocked. 2) There is a large hole- ventricular septal defect- between the two main pumping chambers in the heart. You see, in a normal heart, the blood passes the pulmonary artery to the lungs to collect oxygen. With people who have pulmonary atresia, the blood can’t pass through the artery, so it takes a different route. It…

(7) When the inspired partial pressure of oxygen is 13.3kPa, alveolar oxygen pressure is 8kPa. (7) As hypoxia continues to increase, ventilation rises expodentionally. (7) In the lungs, hypoxia acts as a vasoconstrictor in the pulmonary circulation. (7) The vasoconstriction may help with ventilation and perfusion in the lungs. (7) However, the reflex leads to pulmonary hypertension and is associated with pulmonary edema at high altitudes. (7) In regards to the heart, initially at a high…

Pulmonary TB in the Air Christina E. Santiago San Joaquin Valley College ST:11 Introduction to Surgical Technology Abstract Tuberculosis is a bacterial disease which can affect the lungs or body depending on which part the bacteria has made its home. Pulmonary tuberculosis has two phases on which the bacteria exposes itself. Latent TB, the individual has no signs or symptoms of being ill at all. In this phase, the bacteria will appear at some point in the individual’s lifetime if no testing…

Inhale. Exhale. Our breath, the involuntary action of our bodies taking in air through our lungs and then expelling it, offers us the ability to live. The journey of my life has major twists and turns as well as massive hills and boulders, but it contains the daily sunset and sunrise that gives my life purpose. Although the novel, The Stranger by Albert Camus, demonstrates Monsieur Meursault’s existentialist view of no purpose in life, I find we must live our lives to the fullest and take the…

the lungs over time. A way to test the progression is a pulmonary function testing (PFT’s). This test, tests the lung capacity of a person ("COPD"). This test is simple and is accurate. It involves a patient blowing out into a tube. The force and duration determines the condition of the lungs. With emphysema it is hard to blow out because air pockets form. To tell what stage a person is in most doctors use the GOLD staging system. GOLD stands for “ Global Institute for Chronic Obstruction Lung…

What is asthma? Asthma is a day-and-night lung weakness that lights and limits the air travel routes. Asthma reasons repeating times of wheezing (a shrieking sound when you inhale), mid-section snugness, shortness of breath, and hacking. The hacking regularly happens during the evening or at a young hour in the morning. To comprehend asthma, it knows how the flying routes work. The navigation routes are tubes that do air into and of your lungs. Individuals who have asthma have excited aviation…

obstructive pulmonary disease is any group debilitating, progressive, and potentially fatal lung diseases that have increased resistance to air movement, prolongation of the expiratory phase of respiration, and loss of the normal elasticity of the lung (Ignatavicius & Workman, 2012). Chronic obstructive pulmonary disease includes emphysema and chronic bronchitis. Emphysema is when the air sacs of the lungs are damaged and enlarged. Chronic bronchitis is inflammation of the mucous membrane in…

Gaseous exchange Breathing is the body’s way of exchanging oxygen for carbon dioxide. The lungs get oxygen through alveoli. The air is transported though the trachea and diverted though the bronchi into a lung, the bronchi extends into smaller tubes called bronchioles witch at the end of them are little air sacks (the alveoli). Oxygen is needed to get into the blood stream to allow oxygen to be supplied throughout the body in order for it to function normally. It does this by gaseous exchange.…

and that these continuous requirements are met. Exploring the main role of the respiratory system in this process and its relationship with the cardiovascular system is best explained in 4 main steps. 1. “Uptake in the lungs 2. Carrying capacity of blood 3. Global delivery from lungs to tissue 4. Cellular use of oxygen” (Treacher &…

decreases, stem cells and growth factors increases, which promotes rapid wound healing. Side Effect Definition/Describe A. Pneumothorax: Pneumothorax is defined as a collapsed lung due to the presence of gas or air within the thoracic cavity. B. Air Embolism: An air embolism is also known as a “gas bubble,” and can be defined as block in the vascular system due to an air/gas bubble. C. Oxygen Toxicity: Oxygen toxicity…
