Prior to patient use, a bedside spirometer is calibrated to using a 3 L syringe. Resulting volumes are within 4% of 3.0 L. Which of the following actions should the respiratory therapist perform next?

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?

During a 5 second pause while performing CPR, the respiratory therapist notes no palpable pulse and the following rhythm on the patient ECG monitor is showing:The therapist should do which of the following?

A 65 year old patient recovering from an exacerbation of COPD is weaning from mechanical ventilation. Parameters obtained after a 30-minute CPAP trial with an FIO2 of 0.35 are as follows:VT                                                  350 mlRespiratory rate                   20Minute ventilation               7 L/minArterial blood gas analysis reveals the following data:pH                   7.35PaCO2               45 torrPaO2                  70 torrHCO3                 24 mEq/LBE                   -1 mEq/LThe respiratory therapist should recommend which of the following?

A patient is recieving volume-controlled ventilation with a tidal volume of 0.7 L. The low exhaled volume alarm should be set no lower than:

A 70 kg (154 lb) patient with ARDS is receiving volume-controlled ventilation.

Due to progressive deterioration in arterial blood gas values and continued respiratory muscle weakness, a physician elects to nasally intubate a 50 y/o, 77 kg male patient. Following insertion, the tube was secured with the 25 cm mark at the nare. After attaching a calorimetric CO2 analyzer, the respiratory therapist should note:
