The lungs are a vital part of the respiratory system, a group of organs and tissues that work together to help humans breathe. The system’s main job is to move fresh air into the body while removing waste gases. Lungs are important because every cell in the body needs oxygen to live. The air we breathe contains oxygen and other gases. Once in the lungs, oxygen is moved into the bloodstream and carried throughout the human body. The bloodstream then carries the waste gas back to the lungs where it is removed from the blood stream and then exhaled. The lungs and respiratory system automatically perform this vital process, called gas exchange (American Lung Association). Lungs contain millions of air sacs called alveoli. With each breath, …show more content…
However, with pulmonary edema the alveoli fill with fluid instead of air. Pulmonary edema is the ending result of abnormal build-up of fluid leads to shortness of breath. The term edema itself generally means swelling. This can happen either because of too much pressure in the blood vessels or not enough proteins in the bloodstream to hold on to the fluid in the plasma; the part of the blood that does not contain any blood cells (Medicinenet). This lung condition is usually caused by a number of cardiac and non-cardiac conditions such as: Coronary artery disease, cardiomyopathy, heart valve problems, high blood pressure, acute respiratory distress syndrome, high altitudes, nervous system conditions, adverse drug reactions, pulmonary embolism, and smoke inhalation (Brunner 2015). These many conditions are all health related problems that should be examined by a …show more content…
Using medication will decrease all the pressure that is caused by fluid going around the lungs and heart. Pulmonary edema may be life-threatening, especially without urgent medical treatment and professional assistance. Curing this problem may also be follow the steps of supplement oxygen and medicine. The patient should then follow a low sodium diet to prevent this from being an occurring health problem. Oxygen therapy on a three to five-day treatment will cut down on the chances of having this health condition attacking the Pulmonary system. Follow -up appointments scheduled by a patient that had been diagnosed with Pulmonary edema is critical. Just based off the studies that this wet lung disorder is a chronic build up that is to be controlled and not necessarily cured. Controlling possible risk factors such as salt intake, smoking, cholesterol consumption and taking the prescribed medications will eventually help minimize symptoms and future episodes of edema. On the other hand, it is important to understand that a lot of treatment resolutions can come from self-care which include a low sodium diet and also supportive care which consists of an oxygen therapy treatment. Nevertheless, with a low sodium diet, this a type of diet that restricts salt and other types of sodium. With the oxygen treatment, patients with pulmonary
The risk factors that Jessica presented with are a history that is positive for smoking, bronchitis and living in a large urban area with decreased air quality. The symptoms that suggest a pulmonary disorder include a productive cough with discolored sputum, elevated respiratory rate, use of the accessory respiratory muscles during quite breathing, exertional dyspnea, tachycardia and pedal edema. The discolored sputum is indicative of a respiratory infection. The changes in respiratory rate, use of respiratory muscles and exertional dyspnea indicate a pulmonary disorder since there is an increased amount of work required for normal breathing. Tachycardia may arise due to the lack of oxygenated blood available to the tissue stimulating an increase in heart rate. The pedal edema most probably results from decreased systemic blood flow.
-The patient was having pitting edema and inspiratory rales because the increase of sodium caused an increase of fluid in the vascular system and lungs.
When you breathe in, air containing carbon dioxide (CO2) and oxygen (O2) it moves down your trachea; a tunnel containing cartilage and smooth tissue. Air then travels through two hollow tubes called bronchi; narrow branches lined with smooth muscle, mucosal and ringed cartilage to support the structure. The bronchi divide out into smaller tunnels called bronchioles; are small branches 0.5-1mm, lined with muscular walls to help dilate and constrict the airway. At the end of the bronchioles are little air sacs called alveoli; which assist in gas exchange of O2 and CO2. (Eldridge, 2016) Towards the end of alveoli are small blood vessel capillaries. O2 is moved through the blood stream through theses small blood vessels (capillaries) at the end of the alveoli and the CO2 is then exhaled. (RolandMedically,
The circulatory system and respiratory system share a highly important relationship that is crucial to maintaining the life of an organism. In order for bodily processes to be performed, energy to be created, and homeostasis to be maintained, the exchange of oxygen from the external environment to the intracellular environment is performed by the relationship of these two systems. Starting at the heart, deoxygenated/carbon-dioxide (CO2)-rich blood is moved in through the superior and inferior vena cava into the right atrium, then into the right ventricle when the heart is relaxed. As the heart contracts, the deoxygenated blood is pumped through the pulmonary arteries to capillaries in the lungs. As the organism breathes and intakes oxygenated air, oxygen is exchanged with CO2 in the blood at the capillaries. As the organism breathes out, it expels the CO2 into the external environment. For the blood in the capillaries, it is then moved into pulmonary veins and make
As mentioned above, emphysema affects the alveoli. When you develop emphysema the symptoms may go unnoticed for many years. With emphysema, your alveoli lose their elasticity and that makes it harder for the body to dispel the carbon dioxide. Also, the alveoli will eventually rupture and develop into one larger air sac. (Mayo Clinic)
Healthy lung tissue is predominately soft, elastic connective tissue, designed to slide easily over the thorax with each breath. The lungs are covered with visceral pleura which glide fluidly over the parietal pleura of the thoracic cavity thanks to the serous secretion of pleural fluid (Marieb, 2006, p. 430). During inhalation, the lungs expand with air, similar to filling a balloon. The pliable latex of the balloon allows it to expand, just as the pliability of lungs and their components allows for expansion. During exhalation, the volume of air decrease causing a deflation, similar to letting air out of the balloon. However, unlike a balloon, the paired lungs are not filled with empty spaces; the bronchi enter the lungs and subdivide progressively smaller into bronchioles, a network of conducting passageways leading to the alveoli (Marieb, 2006, p. 433). Alveoli are small air sacs in the respiratory zone. The respiratory zone also consists of bronchioles and alveolar ducts, and is responsible for the exchange of oxygen and carbon dioxide (Marieb, 2006, p. 433).
The Circulatory System is a transportation and cooling system for the body. The Red Blood Cells act like billions of little mail men carrying all kinds of things that are needed by the cells, also RBC's carry oxygen and nutrients to the cells. All cells in the body require oxygen to remain alive. Also there is another kind of cells called white blood cells moving in the system. Why blood cells protect from bacteria and other things that are harmful. The Circulatory system contains vein arteries, veins are used to carry blood to the heart and arteries to carry the blood away. The blood inside veins is where most of the oxygen and nutrients are and is called deoxygenated and the color of the blood is dark red. However, blood in the arteries are also full of oxygen but is a bright red. The main components of the circulatory system are the heart, blood, and blood vessels.
Only the smallest particles of the coal dust make it past the nose, mouth, and throat into the alveoli found deep in the lungs. The alveoli, or air sacs, are responsible for exchanging gases with the blood, and are located at the end of each bronchiole. Microphages, a type of blood cell, gather foreign particles and carry them to where they can either be swallowed or coughed out. If too much dust is inhaled over a long period of time, some dust-laden microphages and particles collect permanently in the lungs causing black lung disease.
The patient I have chosen who has an issue with ventilation and perfusion is A.Z., a
It is when much needed oxygen is obtained by the body in order for respiration to take place and the waste CO2 is taken out of the body. In us mammals, the exchange takes place in the lungs which contain a large number of alveoli. These are sponge-like structures in which the diffusion takes place. They are highly adapted to diffuse the gases as they give a large surface area for exchange of the gases.
In normal breathing, the lungs expand and contract easily and rhythmically within the ribcage. To facilitate this movement and lubricate the moving parts, each lung is enveloped in a moist, smooth, two-layered membrane (the pleura). The outer layer of this membrane lines the ribcage, and between the layers is a virtually imperceptible space (the pleural space), which permits the layers to glide gently across each other. If either of your pleurae becomes inflamed and roughened, the gliding process is impeded and you are suffering from pleurisy. Pleurisy is actually a symptom of an underlying disease rather than a disease in itself. The pleurae may become inflamed as a complication of a lung or chest infection such as pneumonia or tuberculosis, or the inflammation may be caused by a slight pneumothorax or chest injury. The pleural inflammation sometimes creates a further complication by causing fluid to seep into the pleural space, resulting in a condition known as pleural effusion. However, pleurisy is not the only condition that can lead to pleural effusion, it may also be produced by diseases such as rheumatoid arthritis, liver or kidney trouble or heart failure. Even cancer spreading from the lung, breast or ovary can cause pleural effusion. If you have pleurisy, it hurts to breathe deeply or cough, and chest pain is likely to be severe. Accompanying the pain are any other symptoms associated with the underlying disorder. The pain will disappear if a pleural effusion occurs as a consequence of pleurisy, because fluid stops the layers of the pleura from rubbing against each other; however, you may become breathless as the fluid accumulates. In most cases, the risks are those of the underlying cause. A big pleural effusion can compress the lungs and cause breathlessness. Any effusion may lead to empyema. A chest X-ray examination may be required.
Respiration- is the process of air exchange, oxygen is obtained and carbon dioxide is eliminated.
Every cell in the human body requires oxygen to function, and the lungs make that oxygen available. With every breath we take, air travels to the lungs through a series of tubes and airways. After passing through the mouth and throat, air moves through the larynx, commonly known as the voice box, and then through the trachea, or windpipe. The trachea divides into two branches, called the right bronchus and the left bronchus, that connect directly to the lungs. Air continues through the bronchi, which divide into smaller and smaller air passages in the lungs, called bronchioles. The bronchioles end in clusters of tiny air sacs, called alveoli, which are surrounded by tiny, thin-walled blood vessels called capillaries.
The Respiratory System 1. Define respiration. Respiration is the process of converting glucose to energy, which goes to every cell in the body. 2. Describe the organs of external respiration.
Alveolar hyperventilation causes a decreased partial pressure of arterial carbon dioxide (PaCO2). The decrease in PaCO2 increases the ratio of bicarbonate concentration to PaCO2 which increases the pH level. The decrease in PaCO2 develops when a strong respiratory stimulus causes the respiratory system to remove more carbon dioxide than is produced. Respiratory alkalosis can be acute or chronic. Acute respiratory alkalosis is when the PaCO2 level is below the lower limit of normal and the serum pH is alkalemic. Chronic respiratory alkalosis is when the PaCO2 level is below the lower limit of normal, but the pH level is relatively normal or near normal. Respiratory alkalosis is the most common acid-base abnormality observed in patients who are critically ill. It is associated with numerous illnesses and is a common finding in patients on mechanical ventilation. Many cardiac and pulmonary disorders can occur with respiratory alkalosis. When respiratory alkalosis is present, the cause may be a minor or non–life-threatening disorder. However, more serious disease processes should also be considered in the differential diagnosis (Byrd, 2017). Hyperventilation is most likely the underlying cause of respiratory alkalosis. Hyperventilation is also known as over breathing (O’Connell, 2017).
