Which of the following is considered life-threatening?

An intubated patient with chronic obstructive pulmonary disease (COPD) is breathing on pres-sure support ventilation (PSV) 13 cm H2O with positive end-expiratory pressure (PEEP) 5 cm H2O and a flow cycle setting of 25%

The pressure-time scalar shown in the figure is evaluated by the respiratory therapist. What action should the respiratory therapist take at this time? a. The patient and ventilator are synchro-nized and no change should be made. b. The inspiratory flow rate should be in-creased to match the patient's needs. c. The flow cycle setting should be increased to allow more time for exhalation. d. The pressure support setting should be in-creased to match the peak pressure.

Before use in patients, the eluate

a. should be filtered. b. must be centrifuged. c. must undergo quality control testing. d. must be tested for energies emitted.
