Which of the following would occur if PEEP were increased without a corresponding increase in peak pressure? (Ans - The tidal volume would decrease - A physician requests the respiratory therapist to assess the upper airway function of a patient with a fenestrated tracheostomy tube. The therapist should: (Ans - Remove the inner cannula, deflate the cuff, plug the outer cannula - A patient receiving sustained maximal inspiratory (SMI) treatments with a volume-oriented incentive spirometer device begins to inhale through the device 18 times per minute. Which of the following best explains this situation?

An arterial blood gas is drawn and the results are as follows: pH: 7.27 PaCO2: 38 mmHg HCO3: 17 mEq/L PaO2: 44 mmHg Based on this information, the respiratory therapist should do which of the following? (Ans - Ensure that the manual resuscitator is connected to an oxygen source - A COPD patient is brought to the ED after several days of increasing respiratory distress. Baseline blood gases are drawn and the patient is placed on oxygen at 2 LPM via nasal cannula. Data from the original and a subsequent arterial blood sample are as follows: Room Air Sample pH: 7.23
