What is a trigger? Correct Answer: the parameter that starts the inspiratory phase of a positive pressure breath What is the control variable? Correct Answer: the primary variable the ventilator adj ... usts to achieve inspiration What is the limit variable? Correct Answer: Establishes maximum valvue that a variable con reach during inspiration What is the cycling variable? Correct Answer: Ends the breath What are the four types of cycling variables that are available with positive pressure ventilation? Correct Answer: 1. volume 2. pressure 3. time 4. flow What are 3 breaths available with positive pressure ventilation? Correct Answer: 1. Spontaneous=all pt 2. mandatory=vent controls all 3. assisted= pt starts vent finishes What should you consider if there is a low pressure alarm going off? Correct Answer: 1. pt disconnect 2. leak in vent 3. insufficient flow 4. endotrach/trach leak What should you consider if there is a high pressure alarm going off? Correct Answer: 1. pt obstruction (ett,pneumo, raw secretions) 2. equipment obstruction What should you consider if there is a low exhaled volume alarm going off? Correct Answer: 1. pt disconnect 2. low spon Vt Accuracy of ventilators should be verified what devices would verify volume, pressure and flow accuracy? Correct Answer: vol=spirometer pres=mercury or water manometer flow=rotameter What are indications for continuous mechanical ventilation? Correct Answer: 1. Apnea [Show More]
