Final answer:
The recommended amount of downward force applied to the cricoid cartilage during rapid-sequence induction is approximately 1.5 kg.
Step-by-step explanation:
During rapid-sequence induction, cricoid pressure is applied to reduce the incidence of regurgitation. This pressure is applied to the cricoid cartilage, which is located in the neck. The recommended amount of downward force applied to the cricoid cartilage is approximately 1.5 kg (or 15 Newtons).
