Which of the following initial ventilator settings are appropriate for this patient? I. Adjust the sensitivity setting to enable pressure triggering. II. Set an IPAP of 12 cm H2O and an EPAP of 6 cm H2O. III. Institute a backup respiratory rate of 16 breaths/minute. IV. Initiate a PPEP of 10 cm H2O.

A 44-year-old male patient is being mechanically ventilated with a volume-cycled ventilator. The respiratory therapist observes that there is insufficient time for the patient to exhale completely. The therapist should

A patient with congestive heart failure has severe hypoxemia and dyspnea while using a non-rebreather mask. Which of the following interventions would be appropriate for the therapist to institute at this time? I. pressure support ventilation with PEEP II. mask CPAP III. nebulized morphine IV. PRVC

A patient with ARDS is receiving mechanical ventilation with PEEP. The PEEP level is increased from 5 to 10 cm H2O. Which of the following should be monitored by the respiratory therapist to evaluate the patient’s response?

The respiratory therapist reviews the ventilator parament sheet for a patient receiving mechanical ventilation.

The RT performs a patient-ventilator system check on a 24-year-old, 5-foot, 10-inch male patient who has been intubated because of a drug overdose. The RT notices what appears to be swelling around the patient’s upper anterior chest and neck area. Palpation elicits a tissue paper feeling. The ventilator settings are: PC-CMV, rate 12/min with no patient assist, Peak 25 cm H2O, PEEP 5 cm H2O, FIO2 0.4, TI 1.2 s. The most appropriate action for the RT to take is which of the following?

Which of the following provide bedside assessment of patients’ spontaneous breathing? I. spontaneous tidal volume and respiratory rate II. minute ventilation III. rapid shallow breathing index IV. vital capacity
