importance of humidification and suctioning in maintaining airway patency. 4. Awareness of possible problems/complications in tracheostomy management. A normal breathing pattern draws air through the nose or mouth into the trachea and then the lungs but this is not always the case for some patients who need an alternative way to breathe. When breathing become difficult due to an obstruction or narrowing in the windpipe or throat‚ difficulty getting rid of mucus and secretions or a patient need

and Problems Hypoxia Hypoxia arises when there is insufficient oxygen in the body tissues. If not treated quickly‚ hypoxia is potentially fatal. There are a number of causes of hypoxia‚ ranging from suffocation‚ choking or poisoning to impaired lungs or brain functions. Recognitions: In moderate and severe hypoxia‚ there will be: Rapid breathing Breathing that is distressed Difficulty speaking Grey blue skin (cyanosis) – at first‚ more obvious in the extremities (lips‚ nails‚ earlobes)

increased air pollution. Asthma is a widespread‚ degenerative illness that disturbs the outflow of air which goes in and out of the lungs‚ and it affects all people of all ages. This essay will discuss the definition and the distinct types of asthma‚ intrinsic and extrinsic. Asthma is a type III hypersensitivity and a common long-lasting disorder that affects the lungs‚ especially the bronchi. In the early 400’s‚ most of people were suffering from a mysterious disease which was identifies by its symptoms:

ACUTE RESPIRATORY DISTRESS SYNDROME Is a clinical syndrome characterized by a sudden and progressive pulmonaryedema‚ increasing bilateral infiltrates on chest x-ray‚ hypoxemia refractory to oxygensupplementation‚ and reduced lung compliance. These signs occur in the absence of left side failure. Patients with ARDS usually require mechanical ventilation with a higher than normal airway pressure. * PATHOPHYSIOLOGY ARDS Occurs as a result of inflammatory trigger that initiates the release of cellular

Disease (COPD) management is one protocol that is very common within today’s world due to many people smoking. COPD is a lung disease “characterized by persistent airflow limitation that is usually progressive and associated with an enhanced chronic inflammatory response in the airways and the lung to noxious particles or gases”(Global Initiative For Chronic Obstructive Lung Disease‚ 2015). This type of disease causes the patients to have breathlessness while performing their daily activities.

Introduction The lung is a spongy organ made up of of irregularly shaped air spaces called Alveoli. The alveoli are lined by a single layer of flat cells and supported by a mesh of fine elastic fibers. The alveoli are surrounded by a rich network of pulmonary capillaries (Couch and Berger‚ 2004). Our lungs are a network of connected tubes that bring oxygen from the air into our blood‚ nourishing the trillions of cells that make up our bodies. The lungs also clean the blood of carbon dioxide waste

inhale crystalline silica‚ the lung tissue reacts by developing fibrotic nodules and scarring around the trapped silica particles [Silicosis and Silicate Disease Committee 1988]. This fibrotic condition of the lung is called silicosis. If the nodules grow too large‚ breathing becomes difficult and death may result. Silicosis victims are also at high risk of developing active tuberculosis [Myers et al. 1973; Sherson and Lander 1990; Bailey et al. 1974]. A worker’s lungs may react more severely to silica

function? - Residual volume is the volume of gas remaining in the lungs at the end of forced expiration - It is important to normal respiratory function because it helps to keep the alveoli patent (open) and prevent lung collapse. It decreases the efficiency of gas exchange by diluting the oxygen of the inspired air. 2.

the trachea and other airways. 2. Do you see any anatomical reason why the right lung has more lobes than the left lung - and is subsequently larger and heavier? a. The right lung may be larger and heavier because it has more room to develop as such. The heart is roughly centered in the chest cavity; however‚ it is slightly distal to the left of the central midline of the human body. Because of this‚ the left lung must be smaller to compensate for the presence of the heart. 3. What physiological
