Lesson 16:Submersion Incidents Emergency Reference Guide p. 70-75
Objectives • Describe general sequence of events during drowning • Describe safest & most efficient means of removing submersion victim • Describe emergency treatment & long term care for drowned patient • Describe when evacuation is necessary • Describe how to prevent submersion incidents
Submersion Incidents Overview • Submersion incidents include death & near death from drowning • Drowning one of the most common forms of accidental death • Most submersion incidents are easily preventable • What activities have a drowning risk?
Submersion Incidents Overview • Drowning risk activities?: • Fording streams • Seining for bait • Swimming • Snorkeling • Scuba diving • Surfing • Boating • Backpacking • Ice fishing • Ice skating
How Submersion Leads to Death • Non-swimmer can go under in > 1 min., as can hypothermic or injured person • Person panics & struggles while holding breath • Heart rate speeds up, blood pressure rises • Involuntary swallowing of water common. Drive to breath overwhelms the person & he/she breathes in water
How Submersion Leads to Death (cont’d.) • Most people experience “laryngospasm”, involuntary constriction of muscles of upper airway to keep water out of lungs • Laryngospasm leads to asphyxia which is inadequate intake of oxygen • Unconsciousness results • Respiratory arrest, then cardiac arrest • Laryngospasm relaxes, water enters lungs
Preventing Submersion Incidents • What steps can be taken to prevent submersion incidents? • Ensure at least one qualified, responsible adult is trained in water related emergencies • Swim only in safe areas (check area first) • Know how to swim & have appropriate level of fitness • Never swim alone • For boating activities, wear appropriate approved life jackets (PFDs)
Preventing Submersion Incidents (cont’d.) • Wear an appropriate & properly fitting helmet for whitewater boating, water skiing, etc. • Do not dive into shallow water • All water entry feet should be first, unless water is > 7 feet deep & unobstructed • Do not participate in water activities, if under the influence of drugs/alcohol • Exercise care when crossing streams • Do not stand in fast moving water • Limit poor swimmers to shallow water
Recognizing a Submersion Emergency • Timely recognition is key. The way a person behaves in water is your best clue • The manner in which he/she is breathing • Position of the body • How the person uses arms & legs • Ability to make progress in water
Recognizing a Submersion Emergency • “Active” Drowning Victim: • Struggles for breath • Can’t call for help • Arms to sides, alternately moving up & pressing down, ineffectively • Vertical body position • No forward progress
Recognizing a Submersion Emergency (cont’d.) • “Passive” Drowning Victim • Not breathing • No arm or leg motion • Horizontal, or vertical, could be face down or submerged • No forward progress
Reach, Throw, Row, Go • Attempting to save drowning victim requires training & skill • Be sure to know where the rescue equipment is prior to starting activity • Remember to monitor safety of all members of group • Follow reach, throw, row, go guidelines.
Reach, Throw, Row, Go (cont’d.) • Reach with arm, paddle, or pole • Throw, rope, buoy, life preserver • Row out to victim & reach to help • Go (swim) only, if you are excellent swimmer & have training in water rescue. • Don’t allow one victim to become 2!!!
Diving & Spinal Injury • Diving headfirst into shallow water is a major cause of sports related injuries. • If person exhibits signs of spinal injury in water & is breathing, minimize his/her movement • Have a responder who is trained in water rescue provide inline stabilization • If breathing is absent, provide CPR
Activity • Using your backpacks, assemble material that could be used to help save someone who is in the water about 25 feet from land • Practice attaching a buoyant object to a piece of rope. Practice throwing it to someone who is 25 feet from the shoreline • Throw the rope beyond the person without directly hitting him/her
Caring for a Drowned Person • When checking patient what to look for? • Unconciousness • Airway • Breathing • Circulation • Disability • Environmental conditions • If patient is not moving or breathing, begin rescue breathing and CPR
Caring for a Drowned Person (cont’d.) • If patient has suspected back/neck/head injury, provide inline stablization • May have to be performed in the water. Water rescue course will teach this skill • Care for shock, hypothermia or other conditions that may arise
Guidelines for Evacuation • Aspiration (sucking water into the lungs) of even small amounts of water requires prompt medical care, even if patient responds to resuscitation • GO FAST for patient that was unconscious, no matter how short a time • GO FAST if any signs of respiratory distress. Problems can become life threatening • “Secondary drowning,” the after effect of water entering lungs, may take several days to develop
