A patient on ventilatory support has the following flow vs. time waveform: Assessment of this waveform reveals:

A patient in the ICU has a Swan ganz catheter in place with the following results.   CVP – 6 mmHg PAP – 38 mmHg PCWP – 15 mmHg QT – 3 L/min   The results suggest what problem?  

A patient is receiving oxygen at 8 LPM with 50% oxygen via venturi mask. What is the total oxygen flow this patient is receiving?

Autopeep due to air trapping on continuous mechanical ventilation is also known as:

A patient is in the ICU following a MVC has the following data: pH – 7.59 WBC – 9,500 PaCO2 – 48 torr Hct – 30% PaO2 – 78 torr  Hb – 8 g/dl HCO3 – 24 mEq/L Plt – 210 SaO2 – 96% Glucose – 120 g/dl The patient is breathing room air but is tachypneic at 35 breaths/min. Which of the following would you recommend based on these results?

A  female patient on ventilatory support  is intubated with a 7.5 ETT secured at 27 cm mark. The following ventilator settings and parameters are noted: Mode -AC/VC Total Rate – 12 breaths/min Rate – 12 breaths/min Exhaled VT – 600 ml VT – 600 ml VE – 7.2 L/min PEEP – 5 cm H2O FIO2 – 40% The high pressure alarms are being triggered. What should be done at this time?

Which of the following are indications for ventilator discontinuance:       I.      Disease is resolved      II.      Spontaneous VT 5ml/kg      III.      VE  >10 L/min      IV.      NIF of -28

Calculate the VD/VT ratio given the following:      PaO2 = 65 torr      PVO2 = 40 torr      PaCO2 = 65 torr      PECO2 = 30 mm Hg      Tidal volume = 550 ml

On pressure control ventilation, a patient with ARDS will be allowed with permissive hypercarbia at to prevent barotrauma by keeping PaCO2:

The respiratory therapist wants to increase the minute volume for a patient receiving CMV with a on pressure control ventilation (PCV).  Which controls could help accomplish this?  I. Tidal Volume II. Rate III. Flowrate IV. Pressure Limit
