An adult male patient is on CMV intubated with a 8.5 endotracheal tube (ETT). What size suction catheter should the respiratory therapist select to decrease the risk of hypoxemia during suctioning?

What mode of mechanical ventilation is being used after assessment of the the flow vs. time waveform?  

A homeless patient was brought in with a temperature of 29oc breathing slow and shallow with a moderately low blood pressure. This patient is:

A 5′ 6″ female patient was admitted for COPD exacerbation secondary to pneumonia. When the practitioner arrived to assess her and was found to be obtunded with slow shallow respirations. The following arterial blood gas was obtained on a NRB:   pH – 7.22 PaCO2 – 70 torr PaO2 – 68 torr HCO3 – 30 mEq/L     The physician decided to intubate. What initial vent settings should the patient be placed on?

An 80-kg (176-lb) patient is being ventilated in pressure control mode. During a ventilator check, the therapist notes that the compliance has increased from 35 mL/cm H2O to 50 mL/cm H2O. What effect will this change in compliance have on volume?

If the high pressure alarm and low tidal volume alarm goes off on the vent, which of the following should you consider: I. Pneumothorax II. Bronchospasm III. Leak in the circuit IV. Biting the ETT

You are caring for a patient receiving pressure control ventilation when you observe the following airway graphics. Which of the following is the appropriate action? 

What are ways to decrease risks and trauma during nasotracheal suctioning? I. Insertion of a nasopharyngeal airwayII. Suctioning during insertion of a catheterIII. Use of a lubricating gelIV. Suctioning within 15 seconds

The respiratory therapist reviews the ventilator flow sheet for a patient who requires mechanical ventilation following surgery. The ventilator settings have not changed during the past 24 hours. The peak and plateau pressures were recorded as follows: Time PIP Plateau PEEP 7:00 28 23 5 9:00 35 30 5 11:00 49 44 5   This information would indicate that

What phase variable ends the inspiratory phase in a positive pressure breath?
