In Part 10 of R3: Rescue for River Runners, swiftwater rescue instructor Jim Coffey introduces techniques for assessing foot entrapment situations and formulating a plan to assist the victim. Foot entrapment occurs when the foot of a swimmer or wader becomes lodged in rocks or other debris on the river bottom. In a foot entrapment situation, water pressure can make extracting the foot and freeing the victim difficult, while the force of the current can lead to loss of airway, submersion and even drowning.
