Which monitoring device is vital for tracking oxygen saturation levels?

The pulse oximeter is essential for tracking oxygen saturation levels because it accurately measures the percentage of hemoglobin in the blood that is saturated with oxygen. This non-invasive device uses light sensors to analyze the color of the blood, which changes based on the amount of oxygen it carries. This information is crucial in the neonatal and pediatric transport setting, as maintaining adequate oxygenation is critical for the health and well-being of young patients. Monitoring oxygen saturation helps healthcare providers make timely interventions to prevent hypoxia, ensuring that the patient's respiratory needs are met during transport.

In contrast, a thermometer measures body temperature, a blood pressure cuff assesses circulatory status, and an electrocardiogram monitors the electrical activity of the heart, none of which provide information specifically about oxygen saturation levels.
