What are signs that a patient’s inspiratory flow demands are not being met on ventilatory support?   I. Increased accessory muscle use II. Ventilatory muscle atrophy III. Chest retractions IV. Tachypnea

A patient in respiratory failure secondary to asthma bronchitis is on ventilatory support with the following information:   Mode – AC/VC PIP – 35 cm H2O Rate – 15 breaths/min Total rate – 15 breaths/min VT – 500 ml VE – 6 L/min PEEP – 3 cm H2O I:E – 1:3 FIO2 – 0.50 PIF – 30 LPM   The patients chest radiograph suggest flattened diaphragm and increased intercostal spaces. What should be done at this time?

A physician wants to wean a patient that is currently on APRV. How is weaning accomplished on this mode of ventilation?

A patient has an arterial line and the respiratory care practitioner raised the bed to draw from the line for an ABG sample.  The patient’s arterial line site is now higher than the transducer for the A-Line. How will this effect the A-line reading?

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?
