Mechanical Ventilation correct answer: Mechanical ventilation entails the use of sophisticated life-support technology aimed at maintaining tissue oxygenation and removal of carbon dioxide (CO2) - Supports or replaces normal ventilatory pump - Moves air in and out of lungs, or "ventilates" - Provides sophisticated life support Changing Ventilation and PaCO2 correct answer: Partial Support with SIMV correct answer: Box 48-17 Pg. 1106 Effect of change in VA on PaCO2 correct answe...

neuromuscular disease correct answer: Neuromuscular diseases are that group of conditions which affect the strength and ability of muscles to function Maintenance of normal ventilation depends on intact, functional components of the neuromuscular system Regulation of respiratory drive and rateControl of the mechanics of ventilation Cough and other airway protection Consequences of neuromuscular disease correct answer: Disregulation of respiratory drive or rate• Hyperventilation•H...

Allows a gradual rise in CO2 as a lung protection strategy correct answer: Permissive hypercapnia -Patient compliance/resistance --> high resistance reduces speed -Rise time effects speed of how fast inspiratory is -Patient actively breathing *rise time, patient effort, patient compliance and resistance, inspiratory time, flow pattern correct answer: facts that can affect speed by which inspiratory pressure rises to the set pressure value appropriate sized mask correct answer...
