A patient has a history of chronic respiratory failure secondary to COPD and now has
acute respiratory failure secondary to pneumonia. Upon arrival at the critical care unit,
his ABGs were a pH of 7.29, a PaCO2 of 77, a PaO2 of 51, and an HCO3 of 31. He is
receiving noninvasive ventilation with settings that read as follows: FiO2 0.40, IPAP 12
cm, and EPAP 5 cm. After 1 hour of therapy, the patient's ABG results are a pH of 7.20,
a PaCO2 of 89, a PaO2 of 48, and an HCO3 of 32.
What is the correct evaluation of this data?
, (A) Alveolar hyperventilation is getting worse; the BiPAP settings need adjustment.

(C) Alveolar hypoventilation is getting worse; the patient needs to be intubated.
(D) The pH is acceptable for a patient with COPD; continue the current therapy. -
Answers -(C) Alveolar hypoventilation is getting worse; the patient needs to be
