NRNP6566 Week 7 Knowledge check 2

NRNP6566 Week 7 Knowledge check 2 1. Four hours after mechanical ventilation is initiated for a patient with chronic obstructive pulmo-nary disease (COPD), the patient's arterial blood gas (ABG) results include a pH of 7.50, PaO2 of 80 mm Hg, PaCO2 of 29 mm Hg, and HCO3- of 23 mEq/. What change in ventilator settings would be indicated? NRNP6566 Week 7 Knowledge check 2 The patient’s pH is increased and CO2 is decreased indicating respiratory alkalosis. HCO3 is normal. In intubated patients that are mechanically ventilated, hyperventilation may be the cause of the respiratory alkalosis. To correct this, ventilator settings should be changed. The rate should be decreased and the tidal volume should be decreased if necessary during a volume controlled ventilation. If pressure controlled ventilation is utilized, decrease the rate and then decrease the pressure, if needed. ■ ◆ ● O◆ /"! ● ◆ ● ◆◆ #◆ ◆ ●: ■ ● ● ◆ ● ◆ ■ ■ ◆◆ ;◆ ◆ ■ ● * ◆◆ ● % #◆ ●: & This study source was downloaded by from CourseH on 10-11-2021 07:16:40 GMT -05:00 This study source was downloaded by from CourseH on 10-11-2021 07:16:40 GMT -05:00
