1. Preparation: The infant is placed in an appropriate car seat that fits their size and weight. The car seat should be installed following the manufacturer's guidelines. 2. Monitoring: Continuous monitoring of the infant's heart rate, respiratory rate, and oxygen saturation is performed using a pulse oximeter. 3. Duration: The duration of the trial typically lasts between 90 to 120 minutes, simulating the time it might take to travel from the hospital to home. 4. Assessment: During the trial, healthcare professionals watch for signs of respiratory distress, apnea, bradycardia, and desaturation. Any significant drop in oxygen levels or heart rate will be recorded and addressed.
