C) Which structures found in the terminal bronchioles and alveoli normally would protect Cari’s lungs from infectious pathogens and particulate matter? There are macrophages presents (wandering phagocytes) that remove dust particles and other debris from the alveolar space. D) How would the resistance of Cari’s airways be affected by excess mucus and fluid in her lung? The lung capacity is decreased because the air space is already filled with mucus and fluids therefore she can’t take in enough oxygen. The extra mucus and fluids put extra pressure on the lungs.
How would the resistance of Cari’s airways be affected by excess mucus and fluid in her lung? The excess mucus and fluid in the lungs would increase the resistance of Cari’s airways because of the small diameter the buildup would cause and the fluid would have some alveoli underwater where they can’t function properly causing more friction from the buildup. 5. How would Cari’s lung compliance be altered as her alveoli fill with fluid due to pneumonia? Cari’s lung compliance would increase from trying to force gases in and out of the alveoli that are filled with fluid.
The invading organism causes symptoms, in part, by provoking a large immune response in the lungs. The capillaries become leaky, and protein-rich fluid seeps into the alveoli. This results in a less functional area for oxygen-carbon dioxide exchange. The patient becomes relatively oxygen deprived, while at the same time retaining large amounts of carbon dioxide. During this process, mucus production is increased.
1) Coronary artery disease occurs when fatty deposits called plaque build up inside the coronary arteries. The coronary arteries wrap around the heart and supply it with blood and oxygen. When plaque builds up, it narrows the arteries and reduces the amount of blood that gets to your heart. This can lead to serious problems, including heart attack. 2) Coronary artery disease is usually caused by a build-up of fatty deposits on the walls of the coronary arteries.
How was the diagnosis of ARDS made? How important is the medical history? Once again in order to understand why a diagnosis of ARDS was made we must first understand what ARDS is. ARDS is acute respiratory distress syndrome and it come about when fluid builds up in the tiny, elastic air sacs called alveoli in your lungs. More fluid in your lungs means less oxygen can reach your bloodstream.
Smokers’ cough turns into chronic bronchitis, caused by the deteriorated cilia. Mucus thickens and becomes greater in amount, thickening the lining of the bronchioles, resulting in difficulty breathing. The bronchioles steadily lose their elasticity which prevents them from absorbing the pressure on the alveoli, causing the alveoli to rupture; smoking-induced emphysema. This progression results in a worsening cough, wheezing, difficult breathing, and fatigue. As these structural changes are occurring, there are also cellular or molecular changes taking place in the lungs.
The secondary cause is related to an existing infection or disease. Each of these are caused by different irritants that result in the same disruption of normal perfusion. The attacks on the lung lead to alveolar inflammation and edema that causes low ventilation and blood and fluid to be pushed into the capillaries. This leads to a stasis in the lung’s gas perfusion and creates a pressure that makes it harder for the individual to breath (Anatomical Chart Company, 2010, p. 100). The first signs and symptoms of any infection should immediately be put to the attention of the health care provider.
INTRODUCTION Respiratory failure is a sudden and life-threatening deterioration of the gas exchange function of the lung. It exists when the exchange of oxygen for carbon dioxide in the lungs cannot keep up with the rate of oxygen consumption and carbon dioxide production by the cells of the body. DEFINITION Acute respiratory failure (ARF) is defined as a fall in arterial oxygen tension (PaO2) to less than 50 mm Hg (hypoxemia) and a rise in arterial carbon dioxide tension (PaCO2) to greater than 50 mm Hg (hypercapnia), with an arterial pH of less than 7.35. Respiratory failure is inadequate gas exchange by the respiratory system, with the result that levels of arterial oxygen, carbon dioxide or both cannot be maintained within their normal ranges. The normal reference values are: oxygen PaO2 greater than 80 mmHg (11 kPa), and carbon dioxide PaCO2 less than 45 mmHg (6.0 kPa).
When the fats lays in the blood vessels, it increases the size and cause a blockage in the artery which can make a person get low breathing and chest pain. Nervous system Nerves cells communicate with muscle to function properly. In older age neurotransmitters which are released by the nerve cell get weaker to communicate with muscle and function less effectively. Degeneration of the sense organs Sight: - cataracts and glaucoma affect eyesight in older people for the age of 60 upwards. When we get old our lenses changes and become hard and cloudy and it gets stop by cataracts from changing shape or transmit light.
Stroke Awareness Health Assessment The self-risk assessment I chose to complete was about strokes. A stroke occurs when blood supply to the brain is temporarily interrupted or disturbed. Being that the brain requires a constant flow of oxygen any interruptions could prove to be fatal. The two types of strokes are Ischemic or hemorrhagic. An ischemic stroke is typically caused by excess buildup of plague on the blood vessel walls that narrows blood flow dramatically.
