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

The function of the digestive system is to absorb and assimilate key nutrients which are required to maintain and regulate other systems in the body. Enzymes secreted within the digestive system have a role of breaking down food from proteins into amino acids‚ starch into glucose and fats into a mixture of fatty acids and glycerol. The main function of the respiratory system is to inhale oxygen and exhale the waste product carbon dioxide. Oxygen is breathed through the mouth and nostrils into the

The human body has to be controlled from advanced systems internally of which connect in order to function effectively. There are ten main systems within the body of which all perform various activities and all interrelate with at least one other system; the nervous system. The most complex of all body systems‚ the nervous system controls all functions within the body. The main function of the respiratory system is to inhale oxygen and exhale the waste product carbon dioxide. Oxygen is breathed

Neurophysiology of Nerve Impulses ACTIVITY 1 The Resting Membrane Potential 1. Explain why increasing extracellular K+ reduces the net diffusion of K+ out of the neuron through the K+ leak channels. If the extracellular K+ increases then the concentration of intracellular K+ will decrease causing a decrease in the steepness of the concentration gradient and fewer K+ ions would be drawn out. 2. Explain why increasing extracellular K+ causes the membrane potential to change to a less negative

Maximal Velocity Sprint Mechanics Michael Young United States Military Academy & Human Performance Consulting Sprinting is a complex task that places a high neuromuscular demand on the performer and requires high levels of coordinated movement and appropriate sequencing of muscle activations to perform at peak levels. This paper will examine maximal velocity sprint mechanics with particular focus on the primary factors affecting performance‚ the mechanics associated with those factors‚ and the

11Circulatory and Respiratory Flipped Resources Student Learning Objectives Central Concepts: There is a relationship between the organization of cells into tissues and the organization of tissues into organs. The structures and functions of organs determine their relationships within body systems of an organism. Homeostasis allows the body to perform its normal functions. Explain how the circulatory system (heart‚ arteries‚ veins‚ capillaries‚ red blood cells) transports nutrients and oxygen to cells and removes cell wastes
