Being saved in a hypothermic state doesn’t mean you’re safe. many hypothermia victims die each year in the process of being rescue. why does rewarming the body too quickly lead to death?

Certain treatments can be used to warm up the body during hypothermia, But, body tissue can be damaged if you do not correctly treat hypothermia with certain types of treatments. For example. If you are treating someone with hypothermia, you cant just get a bucket of hot water and throw it on them, It'll kill the nerves and cells in the area affected, Just like taking a hot shower if your really cold, again not a smart idea.

Rewarming too quickly can lead to arrhythmia (irregular heart rate), or Bradycardia (slow heart rate).

i don't think so because different teachers have different materials. tehy teach differently, unless you know for sure your teacher is the exact same as others. i would just contact ur teacher
