Systems thinking contrasts with reductionism by:

Which of the following occur in pressure control ventilation? I. As the pressure limit is increased, tidal volume delivered also increasesII. Inspiratory flow decelerates during the inspiratory cycleIII. As airway resistance increases, tidal volume decreasesIV. As compliance decreases, tidal volume increases

A 80 kg (176 lb) patient with pulmonary fibrosis is mechanically ventilated at the following settings: Mode: SIMV VC VT: 700 mL Mandatory Rate: 15/min Total Rate: 15/min FiO2: 0.40 PEEP: +10 cmH2O I:E Ratio: 1:2 Arterial Blood Gas analysis reveals the following: pH: 7.34 PaCO2: 55 torr PaO2: 50 HCO3-: 22 mEq/L     The respiratory therapist should recommend

On volume control ventilation, what can the respiratory care practitioner do to decrease air-trapping?

The respiratory therapist reviews a ventilator parameter sheet and notes that the peak inspiratory pressure has been gradually rising for the past several hours. Which of the following could be contributing to this change? 1. Bronchospasm 2. Increasing pulmonary compliance 3. Accumulation of secretions 4. Decreasing airway resistance

Which of the following are variables controlled during AC/PC mechanical ventilation? I. VolumeII. FlowIII. TimeIV. Pressure

An adult comatose patient on CMV is endotracheally suctioned with a closed 14f catheter for retained inspissated secretions. The suction pressure is set at -150 mm H2O. What should the therapist do next?

Your patient’s clinical status abruptly changed and unstable, the alarms on the ventilator are triggered. What is/are the first step(s) you should take?

The patient has a back up rate of 20 breaths/min with a 1 second I:time on pressure control ventilation. What is the patient’s I:E ratio?

What are ways to decrease risks and trauma during nasotracheal suctioning? I. Insertion of a nasopharyngeal airwayII. Suctioning during insertion of a catheterIII. Use of a lubricating gelIV. Suctioning within 15 seconds
