Chapter 11 ARDS INTRODUCTION Acute respiratory distress syndrome (ARDS) - lung inflammation seen at the level of the alveolar capillary membrane with increased vascular permeability. ARDS results in: bilateral pulmonary edema and atelectasis despite no evidence of left heart failure (e.g.‚ normal pulmonary capillary wedge pressure (PCWP). ARDS is present when the ALI results in such severe hypoxia that at the PaO2/FIO2 ratio is 200 mm Hg or less. Approximately 10% to 15% of intensive care

categories: acute and chronic.[1][2][3][4] Acute bronchitis is characterized by the development of a cough or small sensation in the back of the throat‚ with or without the production of sputum(mucus that is expectorated‚ or "coughed up"‚ from the respiratory tract). Acute bronchitis often occurs during the course of an acute viral illness such as the common cold or influenza. Viruses cause about 90% of acute bronchitis cases‚ whereas bacteria account for about 10%.[5][6] Chronic bronchitis‚ a type

The respiratory and cardiovascular systems work in different ways with different functions in realtion to the metabolism and with the use of energy. The cardiovascular system in the human body is made up of the heart and blood vessels‚ which are divided into arteries‚ veins and capillaries. The heart is responsible for pumping the blood throughout the blood vessels and is divided into four chambers‚ two of which are responsible for moving deoxygenated blood and two of which move oxygenated blood

This particular job did not require us to attend under emergency response‚ this immediately made me feel relaxed and able to focus on my existing knowledge of respiratory pathophysiology. I foolishly had not anticipated any real worries or concerns‚ as it appeared to be a straightforward transportation from GP surgery to hospital. On arrival I was surprised to find the patient unattended and untreated in a room with no HCP present. I felt extremely concerned there had been no monitoring performed

can affect the respiratory system. The first effect is‚ eating fast food can lead to obesity which affects the respiratory system by decreasing the volume of the lungs. This lowers the forced expiratory volume in one second. It also lowers the vital capacity. This also lowers functional residual capacity. That is one effect of fast food on the respiratory system. The second effect is‚ that fast food causes causes obesity around the abdomen which worsens lung functions and respiratory symptoms. This

The effect of acute exercise on the Musculoskeletal‚ Energy‚ Cardiovascular and Respiratory Systems Andrew White Musculoskeletal System There is an increase in blood supply as your body is working overtime. The blood supply has to increase because it has to go to the parts in your body which you are exercising the most e.g. If you are taking a run‚ the blood supply will increase because your legs will need more energy‚ therefore there will be more blood circulating your legs than normal because
