Respiratory- Mechanical Ventilation questions with answers What parameters regarding respiratory rate might indicate the need for mechanical ventilation? - ANSWER: ✔✔greater than 35 or less than 10 What parameters regarding pressure of arterial O2 and FIO2 might indicate the need for mechanical ventilation? - ANSWER: ✔✔PaO2 less than 60mmHg with FIO2 greater than 60% What parameters regarding PaCO2 and pH might indicate the need for mechanical ventilation? - ANSWER: ✔✔PaCO2 greater than 50mmHg with pH less than 7.35 Besides respiratory rate, PaO2, FIO2, PaCO2, and pH what other two factors might indicate the need for mechanical ventilation? - ANSWER: ✔✔absent gag or cough reflex Positive pressure ventilation implies what? What's absent? - ANSWER: ✔✔air is being forced into the patient's lungs, thorax expansion PEEP can be applied to what two kinds of patients? - ANSWER: ✔✔mechanical ventilation patient and spontaneously breathing patient PEEP increases what two factors? - ANSWER: ✔✔oxygenation and lung compliance PEEP decreases what two factors? - ANSWER: ✔✔work of breathing and shunt fraction PEEP is primarily used in what type or types of patients? - ANSWER: ✔✔Hypoxic Respiratory Failure COPD patients may benefit from how many cm H2O PEEP to prevent airway collapse? - ANSWER: ✔✔3- 5 What is the goal in using PEEP for COPD patients? - ANSWER: ✔✔PaO2 greater than 60mmHg with an FIO2 less than 60% What are the three aspects/steps of ventilation therapy? - ANSWER: ✔✔initiation, management, weaning What are the two general types of ventilation? - ANSWER: ✔✔pressure-targeted and volume-targeted What are the four settings you need to know to setup the mechanical ventilator in VOLUME-TARGETED therapy? - ANSWER: ✔✔Mode, Tidal Volume, Rate, FIO2%, Peak Flow, PEEP (Manage Their Respiratory Fill Pronto Peeps) What are the six settings you need to know to setup the mechanical ventilator in PRESSURE-TARGETED therapy? - ANSWER: ✔✔Mode, Peak Pressure, Rate, I:E Ratio, FIO2, PEEP (Manage Pressure of Respiration In Failing Peeps) What disease process commonly needs PEEP? - ANSWER: ✔✔ARDS Which ventilatory setting, which can automatically deliver air or can be triggered by the patient's effort, delivers a set tidal volume to the patient on a given interval? - ANSWER: ✔✔Assist Control Mode Ventilation (ACMV) A patient in the ICU is on assist control ventilation mode with a rate of 14 and has became very nervous about his current condition. This anxiety causes him to increase his respiratory rate to nearly 28 times per minute. What is this most immediate concern? What should we do to alleviate this issue? - ANSWER: ✔✔The most immediate concern is hyperventilation leading to respiratory alkalosis. We should give the patient a sedative to slow his respiratory rate. What ventilatory setting gives a set amount of breaths per minute at a certain volume or pressure regardless of what the patient does? - ANSWER: ✔✔intermittent mandatory ventilation Unlike assist control mode ventilation, this mode of ventilation will give the patient a set volume of air at a set interval but not beyond what the physician has ordered. As such, the risk for hyperventilation and respiratory alkalosis is minimized. - ANSWER: ✔✔Synchronized Intermittent Mandatory Ventilation
