A patient has recently been diagnosed with obstructive sleep apnea. The most appropriate treatment includes which of the following? correct answer: Continuous positive airway pressure (CPAP) A home care patient diagnosed with central sleep apnea would benefit from which of the following modes of ventilation? correct answer: Noninvasive positive pressure ventilation (NIV) What type of breath occurs when the ventilator controls the timing, tidal volume, or inspiratory pressure? correct answer: Mandatory Which of the following is the minimum ventilator rate that is considered full ventilatory support? correct answer: 8 breaths/min Of the following breath descriptions, which one is considered spontaneous? correct answer: Patient triggered, patient cycled, baseline pressure +5 cm H2O The ventilator mode where every breath is patient triggered, pressure targeted, and flow cycled with a volume target is which of the following? correct answer: Volume support ventilation (VSV) The ventilator mode that delivers pressure breaths that are patient or time triggered, volume targeted, time cycled, and where the pressure is automatically adjusted to maintain delivery of the targeted volume is which of the following? correct answer: Pressure-regulated volume control (PRVC) A patient, who is nasally intubated, due to facial surgery, has been successful on her spontaneous breathing trial. She currently has moderate hypoxemia, despite a fractional inspired oxygen (FIO2) of 40% and positive end-expiratory pressure (PEEP) of 5 cm H2O while on volume-controlled continuous mandatory ventilation (VC-CMV). The most appropriate ventilator mode for this patient is which of the following? correct answer: Intermittent mandatory ventilation (IMV) with pressure support ventilation (PSV) and positive end-expiratory pressure (PEEP) In which of the following patient situations would you try NIV? correct answer: A patient with COPD and RLL pneumonia with respiratory acidosis and increased WOB. Which of the following is/are circumstances when it is appropriate to use PSV? 1. As a weaning method 2. To overcome the WOB through the ETT and the patient vent circuit 3. For patients using the IMV mode 4. For long-term patient support correct answer: 1, 2, 3 and 4 An ICU patient is on PC-CM
