Following chest percussion, a respiratory therapist auscultates a patient’s chest and hears coarse low-pitch, gurgling sounds around the hilar area. These sounds should be recorded in the patient’s medical record as:

A patient with history of shortness of breath has a FEV1 of 1.0 L before use of a bronchodilator and a FEV1 of 1.25 L after use of a bronchodilator. These results indicate:

A 26 year old patient has been receiving mechanical ventilation in the assist/control mode for 48 hours. The sensitivity is set at -2 cm H2O. The patient is awake and periodically breathing out of phase with the ventilator.

A physician ordered an increase in PEEP from 5 to 10 cm H2O for a patient receiving mechanical ventilation. Immediately after the new PEEP setting was initiated, the patient’s blood pressure decreased from 130/86 mmHg to 110/74 mmHg, and the heart rate increased by 30/min. Which of the following should the respiratory therapist recommend to the physician?
