Define intrinsic PEEP.

A patient is receiving continuous mechanical ventilation.  Settings and parameters are as follows:Mode  Assist/Controlf         14 bpmVT          800 mLFiO2           0.45PEEP          10 cmH2OPIP          45 cmH2OPplateau         35 cmH2OTubing compliane    3 ml/cmH2OUtilizing the corrected VT, determine the dynamic compliance?

PEEP accomplishes its primary purpose by .

A mechanically ventilated patient is going to be placed on pressure support ventilation following an acceptable spontaneous weaning trial. The patient is a 5’9″ male who weighs 185 lb. During volume-controlled continuous mandatory ventilation (VC-CMV) his average peak inspiratory pressure (PIP) was about 26 cm H2O and the plateau pressure (PPlateau) was 11 cm H2O. What initial pressure support level should be set?

Calculate the inspiratory to expiratory (I:E) ratio for a ventilator that is set to deliver 500 mL at a frequency of 15 breaths/min with a flow rate of 60 L/min.

In the simplest of terms, a is required for air to flow from the mouth to the alveoli.

While monitoring a patient during a T tube weaning trial, you notice the following: increased patient agitation; increased heart rate (from 90 to 118/min); increased respiratory rate (from 17 to 33/min with some paradoxical motion); and premature ventricular contractions (PVCs) increasing to an average of 5/min. Which of the following actions would be appropriate at this time?

Which of the following drug categories can depress ventilatory drive and hinder weaning?1. Analgesics2. Narcotics3. Hypnotics4. Antibiotics

An alert patient receiving ventilatory support through a demand flow intermittent mandatory ventilation system exhibits clinical signs of an increased work of breathing whenever you try to decrease the mandatory rate below 6/min. In order to aid in weaning this patient, which of the following would you recommend?

The pathogenesis of VAP involves:1. colonization of the aerodigestive tract.2. aspiration of contaminated secretions into the lower airways.3. increased use of silver-coated endotracheal tubes.4. colonization of lower airways and lung parenchyma.
