Exam 24: Noninvasive Positive-Pressure Ventilation

The respiratory care practitioner is called to the medical intensive care unit to evaluate a pneumonia patient for impending ventilatory failure.Arterial blood gases (ABGs)are drawn and the results are as follows: PaO₂ 49 mmHg,PaCO₂ 58 mmHg,pH 7.24,HCO₃ 23 mEq/L,FIO₂ 0.6.What do the patient's ABGs indicate?

A physician orders a patient to be placed on NPPV.The physician wants the patient to breathe spontaneously with assistance,but since the patient has frequent apneic episodes,she also wants the patient to have a back-up rate.Which mode should the practitioner recommend to the physician?

How do patients with chronic obstructive pulmonary disease (COPD)benefit the most from noninvasive positive-pressure ventilation?

Which of the following is NOT a sign of increased ventilatory work?

A respiratory care practitioner is asked to evaluate a patient for impending ventilatory failure.The practitioner measures a Vt of 350 ml with respiratory rate of 25/min on the patient.What should the practitioner report to the physician as the patient's actual RSBI value?

A patient complains of eye irritation and dryness.Which of the following would the practitioner NOT use to correct this problem?

What can be accomplished by blocking the mask interface and placing the ventilator into the timed mode with a set rate?

In the spontaneous mode of NPPV,how long is the EPAP pressure maintained during the expiratory phase?

Which of the following is NOT an advantage of a nasal mask for NPPV?

What is defined as the application of positive pressure via the upper respiratory tract for the purpose of augmenting alveolar ventilation?

Noninvasive positive-pressure ventilation has been applied the most to patients with what diagnosis?

A patient on NPPV has an increase in lung compliance.If the set pressure remains the same what will happen to the delivered Vt?

If the patient's airway resistance increases during NPPV,what will happen to the patient's inspiratory time?

Which of the following is NOT an indication for noninvasive positive-pressure ventilation (NPPV)in acute respiratory failure?

In the spontaneous mode of ventilation,how is the breath from the ventilator initiated?

Which of the following ventilatory parameters would indicate that a patient has impending ventilatory failure?

A patient on a full face mask on noninvasive positive-pressure ventilation (NPPV)is swallowing air and having trouble exhaling due to a leak around the naso-gastric (NG)tube.What can be done?

A COPD patient is being ventilated on a noninvasive positive-pressure ventilation (NPPV)in the spontaneous/timed mode of ventilation.The ventilator is not triggering each time the patient attempts to initiate a breath.What can be done?

What should be monitored to determine whether NPPV is meeting the patient's oxygenation requirements?

Which of the following is another name for the peak inspiratory pressure achieved during BiPAP ventilation?
