The venturi gate on the BirdMark 7A will close when pressure in the pressure chamber reaches approximately:

The primary difference between the Percussionaire IPV-2 and IPV-1C is:

Volume delivery for the Percussionaire IPV-1C ventilator is controlled by the:

Which of the following are hazards or complications of Intermittent Positive-Pressure Breathing (IPPB) according to the American Association for Respiratory Care (AARC) Clinical Practice Guideline: Intermittent Positive-Pressure Breathing? I. increased airway resistance II. barotrauma III. impedance of venous return IV. gastric distension

When performing positive end expiratory pressure (PEP) therapy, a desired pressure range to achieve during exhalation is:

Which of the following adjuncts for chest physiotherapy may be used for chest physiotherapy on premature infants?

Indications for incentive spirometry include which of the following according to the American Association for Respiratory Care (AARC) Clinical Practice Guideline: Incentive Spirometry? I. conditions predisposing atelectasis II. presence of atelectasis III. restrictive lung defect associated with neuromuscular disorders IV. delivery of a medication

F_IO₂ delivery increases during inspiration while the BirdMark 7A is operating using air mix. Which of the following contribute to this fact? I. Increasing pressure in the pressure chamber decreases air entrainment. II. At 12 cmH₂O, the venturi gate closes. III. After about 12 cmH₂O, gas flow through the circuit is source gas. IV. Excess flow (source gas) is directed through the timing cartridge.

Which of the following adjuncts for chest physiotherapy help compensate for poor manual percussion technique?

You are using the BirdMark 7A for IPPB therapy. What prevents gas from escaping from the circuit to the ambient air during inspiration?

A patient is using a Tri-flow incentive spirometer. She can raise the second ball to the top of the chamber for 2 seconds. How much volume did the patient inhale?

When using a BirdMark 7A, changing the pressure control to increase the pressure will cause the: I. tidal volume to decrease II. tidal volume to increase III. inspiratory time to increase IV. inspiratory time to decrease

The center body of the BirdMark 7A ventilator contains: I. the ceramic switch and clutch plates II. the venturi III. the timing cartridge IV. the flow-rate control

You are using the BirdMark 7A ventilator for IPPB therapy. The ventilator cycles on and off rapidly, frustrating your patient. What control should you manipulate?

When using the BirdMark 7A ventilator, manipulating the flow-rate control to decrease the flow will cause the: I. tidal volume to decrease II. tidal volume to increase III. inspiratory time to increase IV. inspiratory time to decrease

When the patient depresses the thumb button on the IPV-1C circuit:

When instructing a patient to use an incentive spirometer, you should tell the patient I. "Put the mouthpiece in your mouth and inhale as quickly as possible until your lungs are full." II. "Put the mouthpiece in your mouth and inhale slowly until your lungs are full." III. "When your lungs are full, briefly hold your breath." IV. "Put the mouthpiece into your mouth and blow hard."
