Mr. Darcy is intubated receiving CMV. His physician has orders for HFOV. What is an appropriate ventilator setting for this patient? Mode –  AC Total Rate – 18 breaths/min Rate – 18 breaths/min Exhaled VT – 400 ml Volume – 400 ml PIP – 40 cm H2O PEEP – 10 cm H2O Plat – 30 cm H2O FIO2 – 1.0 MAP – 12 cm H2O therapist set the mean airway pressure on the new mode

A patient currently has a pulmonary artery catheter post-op due to GSW. The patient is in the SICU on mechanical ventilation. The following hemodynamics are as follows:   CVP – 2 mmHg MPAP – 8 mmHg PCWP – 5 mmHg QT – 3.5 L/min   The results suggest what problem?

Which of the following techniques can be used to improve oxygenation beyond increasing the FIO2 or PEEP level?       I.      Proning the patient      II.     Use of an expiratory pause      III.    Increasing inspiratory time      IV.    Increasing tidal volume  

A patient with a Swan Ganz catheter post CABG. The bed is lower than the transducer set on the I.V pole. How will this effect the hemodynamic readings?

An optimal PEEP study was being done with the following: PEEP SpO2 Blood Pressure 8 80% 125/80 10 90% 120/79 12 92% 105/70 14 93% 102/68 What is optimal PEEP?

Calculate the VD/VT ratio given the following:      PaO2 = 85 torr      PvO2 = 39 torr      PaCO2 = 45 torr      PECO2 = 25 mm Hg      Tidal volume = 440 ml

A  female patient on ventilatory support  is intubated with a 7.5 ETT. Cuff pressure was measured at 18 mmHg. The following ventilator settings and parameters are noted: Mode -AC/VC Total Rate – 12 breaths/min Rate – 12 breaths/min Exhaled VT – 400 ml VT – 600 ml VE – 4.8 L/min PEEP – 5 cm H2O FIO2 – 40% The low volume and low pressure alarms are being triggered. What should be done at this time?

The respiratory therapist wants to increase the minute volume for a patient receiving continuous ventilation with a pressure-controlled ventilator.  Which controls could help accomplish this?       I.      Tidal Volume      II.      Rate      III.      Flowrate      IV.      Pressure Limit     

Of the following values, which ABG represents absolute respiratory failure?  

A patient in the medical intensive care unit is intubated due to respiratory failure due to pulmonary fibrosis. The ventilator settings are as noted below: Mode – AC Total Rate – 20 breaths/min Rate –  20 breaths/min Exhaled VT – 350 ml Pressure – 30 VE – 7.0 L/min PEEP – 10 cm H2O PIP – 40 cm H2O FIO2 – 1.0 MAP – 23 cm H2O The patient’s physician wants to place the patient on APRV. What P-High should be started on the new mode?
