A 50-year-old male patient presents with acute respiratory distress due to acute exacerbation of chronic obstructive pulmonary disease (COPD). The patient is alert and oriented but experiencing labored breathing with an SpO2 of 85% on room air. Non-Invasive Ventilation (NIV) is initiated. Which of the following clinical signs indicates that NIV is effective for this patient?
The effectiveness of NIV in patients with respiratory distress is primarily indicated by improvement in clinical signs such as alleviation of labored breathing, increased oxygen saturation levels, and improvement in arterial blood gases. Specifically, an increasing SpO2 to above 90% after starting NIV suggests that the intervention is providing adequate respiratory support. On the other hand, absent breath sounds or accessory muscle usage might indicate progressing severity, and bradycardia may suggest hypoxia or other complications.
