Omar, Chief Nurse at the Integrated Health Center, clips a pulse oximeter device onto a patient to measure two vital indicators: oxygen saturation (SpO2) and heart rate. These measurements are crucial for detecting respiratory issues and ensuring proper oxygenation, especially in young children who are most at risk. The Save the Children USAID Kulawa Project in Niger trained Omar and other team members on the use of the pulse oximeter. Djamila Ibrahim / Integrated Health Center, Niger
