The main complaint of a 64-year-old female with a history of chronic obstructive pulmonary disease (COPD) who visited the emergency room (ED) was that his shortness of breath had gotten worse during the previous two days. After a recent upper respiratory infection, the SOB started. His oxygen saturation on room air in the ED is 88%. He is speaking in fragments and appears to be quite exhausted while complaining of acute dyspnea. The following are his vital signs: HR: 132 beats/min RR: 28 breaths/min BP is 151/93 mm Hg. diffuse wheezes and a protracted expiratory phase are the lungs’ noises. ABG results for arterial blood reveal a pH of 7.12, a PaCO2 of 78 mm Hg, a (HCO3-) concentration of 32 mEq/L, and a PaO2 of 61 mm Hg.
1. Explain the ABG above.
2. What are the indications that mechanical ventilation should be initiated?
3. The doctor seeks advice on how to alleviate the patient’s current respiratory distress. What do you recommend?
4. What do you think about the prospect of this patient receiving noninvasive ventilation (NIV)?
