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?

What is the brand name for tiotropium bromide?

A 62-year-old male patient has survived a myocardial infarction but is apneic at this time.  The physician has asked the respiratory therapist to place the patient on mechanical ventilation. The patient is 5 ft 10 inches tall. Which of the following would be the most appropriate initial ventilator settings:           

A chest x-ray of a patient with left pneumothorax will look like: I.      Hyperlucent on the left lung II.     Flattening of the left hemidiaphragm III.    Tracheal shifting to the left IV.     Mediastinum shifting to the right
