Any physician, surgeon, nurse, or licensed mobile emergency medical technician may in good faith render emergency care or assistance, without compensation, at the scene of an emergency or accident, and will not be liable for civil damages as a result of acts or omissions unless caused by gross negligence or by willful or wanton acts or omissions. Also protected by this law is anyone trained to provide first aid in a standard recognized training program, as long as he or she provides aid only to the level for which he or she has been trained (MO Rev. Stat. Sec. 537.037).
