Title: Drowning: Submersion Emergencies
1Drowning Submersion Emergencies
- Presence Regional EMS
- June 2015 CE
2Objectives
- Define drowning
- Discuss the incidence, risk factors and
prevention of drowning - List the basic rules of providing water rescue
- Outline recovery techniques and resuscitation
efforts required for submersion injuries
3Submersion Emergencies
4Introduction
- Drowning emergencies are emotionally traumatic
for relatives and loved ones of the patients and
emergency providers. - Many drownings are preventable tragedies
resulting from poor judgement, alcohol
consumption and inadequate supervision of
children.
5Incidence
- There are an estimated 4,500 drowning related
deaths in the United States every year. - For every drowning death
- 2 people drown and survive with no disability.
- 2 people drown and survive but have severe
neurological impairment
6The Numbers May Not Be Accurate
- Victims of drownings from floods and other
natural disasters are not counted in drowning
deaths. - Victims of boating accidents are not counted in
drowning deaths.
7Who drowns?
- Children under the age of 4 years and adolescents
and young adults aged 15 to 24 years make up the
majority of drowning victims. - Water sports and the use of alcohol and/or drugs
while swimming increase ones chance of suffering
a submersion related injury.
8Submersion Emergencies
- Immersion
- An incident in which a patients face and/or
airway are covered in water - Submersion
- An incident in which a patients entire body
including the face and airway is submerged in
water - Water Rescue
- An incident in which a person is alert but
experiences some distress while swimming with
minimal or transient symptoms
9- Drowning
- An event in which a patient has primary
respiratory impairment from immersion or
submersion in a liquid. The patient may live or
die after this event. - Drowning Death
- An event of drowning in which the patient is
pronounced dead within 24 hours of the event.
Pronouncement may occur on scene or at the
hospital. - Drowning-related Death
- Incident in which a submersion patient dies more
than 24 hours following the event.
10- The best treatment for drowning is prevention.
11Prevention
- Many drowning victims are infants and small
children. - Prevention can be a matter of following some
common sense practices.
12Prevention of Drowning
- Keep only a few inches of water in the bathtub
when bathing young children. - Never leave young children unsupervised in
bathtubs. - Never leave children alone in or near a pool EVEN
FOR A MOMENT regardless of safety precautions
such as self locking gate and pool alarms.
13- Be sure that adults and adolescents are trained
in CPR so that they can rescue a child if
necessary. - Surround pools on all 4 sides with a sturdy five
foot fence. The house should not be one of the
barriers to the pool if there is a doorway from
the home to the pool area. - Be sure that gates self-close and self-latch at a
height that children cannot reach.
14- Keep rescue equipment (shepherds hook and life
preserver) and a portable phone near the pool. - Avoid inflatable swimming aids such as
floaties. They are not a substitute for
approved life vests and can give children a false
sense of security. - Whenever infants and toddlers are in or around
water, an adult should be within arms length,
providing touch supervision.
15Where People Drown
16Why Do Drownings Occur?
- Swimming/boating issues
- Exhaustion in the water
- Losing control or being swept into deep water
- Becoming tangled or entrapped while in the water
- Using poor judgment while in or near water
- Panicking while in water
- Losing a support such as a sinking boat
-
17- Precipitating Factors
- Using alcohol or drugs in or near the water
- Suffering a seizure, heart attack, or other
debilitating condition while in or near water - Becoming hypothermic while swimming
- Suffering trauma or a diving accident
18Pathophysiology of Drowning
- Victims airway is below the surface of a liquid
- Victim involuntarily holds breath
- Water swallowing begins into posterior pharynx
and into stomach - Involuntary laryngospasm (closing of vocal cords)
due to liquids in the oropharynx.
19(No Transcript)
20- Blood oxygen levels drop and carbon
- dioxide levels raise.
- Due to worsening low oxygen/high carbon dioxide
and unconsciousness laryngospasm stops and vocal
cords open. - Gasp reflex if the victims head is out of the
liquid may begin coughing and clearing airway
21- If the victims head is still under the liquid,
liquid enters the lungs. - Surfactant washout occurs
- Worsening hypoxia
- Cardiac arrest
- DEATH
22Drowning Process
23Predicting the Outcome of Drowning
- Duration of submersion
- Severity of hypoxia
- Neurologic impairment due to lack of oxygen to
the brain
24- Drowning victims who have spontaneous
respirations and pulses in the field before
arrival in the Emergency Department usually
recover with good neurological outcomes.
25Surviving Drowning/Time
Duration of Submersion Likely to Survive without Neurological Damage
0 to up to 5 minutes 90
5 up to 10 minutes 44
10 up to 25 minutes 12
25 minutes or longer 0
26Surviving Drowning/Clinical Findings
Initial Clinical Findings Likely to Survive Without Neurological Damage
Some coughing, normal breath sounds 100
Coughing, with wet rales in one lung 99.4
Coughing, bilateral wet rales or pulmonary edema, good vital signs 95
Coughing, bilateral wet rales or pulmonary edema, low BP 80
No spontaneous respirations, pulse is present 56
Cardio/pulmonary arrest, no spontaneous breathing, no pulse 7
27Drowning Related Death
- People die in the hospital after a drowning
incident because of - Brain death from lack of oxygen
- Acute respiratory distress syndrome
- Multi-organ system failure
- Sepsis (system wide infection)

29Management of Submersion Emergencies
30Management
- Rescue
- Airway/Ventilation
- Hypothermia
- Associated Trauma
31Rescue
- Provider Safety
- Dont Jump in to Help if you Cant Swim!!!
- Make use of a conveyance device
- Boat
- Raft
- Floatation device
32If you are the only rescuer. . .
- If the victim is not breathing provide 2 minutes
of rescue breaths before calling 911. - If the victim is pulseless
- and not breathing provide
- 5 cycles of CPR (2 minutes)
- before calling 911.
33Airway/Ventilation
- The most dangerous consequence of submersion
emergencies is lack of oxygen. - Open the victims airway as soon as possible and
begin assisted ventilations. - Rescue breathing should begin as soon as a
submersion victim is removed from the water.
34- Lets practice airway management
- Practice opening airway and BVM ventilation
- One rescuer and two rescuer
35THERE IS NO NEED TO DRAIN WATER FROM THE LUNGS
- Fluids in the airway and lungs of a submersion
victim absorb quickly - Most water will come from the stomach
36No Heimlich Maneuver!!
- Routine use of the Heimlich Maneuver or chest
compressions to remove water only leads to - Vomiting
- Aspiration
- Delay in beginning
- ventilations
37Vomiting
- 67 of submersion victims who require ventilation
assistance vomit. - 86 of submersion victims who require ventilation
and chest compressions vomit - If vomiting occurs turn the patient on their side
and suction -
38Body Temperature Hypothermia
- Body requires core temp of 98.6oF (37oC) for
proper function. - If core temp significantly rises above or falls
below 98.6oF (37oC), the cells ability to
function is impaired, especially those of the
brain, heart, and kidneys. - Can result in permanent disability and/or death
of the patient.
39Submersion and Hypothermia
- Mammalian Diving Reflex
- The mammalian diving reflex activates when a
person dives into cold water (lt70oF). - Larynx spasms.
- Breathing is inhibited.
- Heart rate slows.
- Blood vessels constrict.
- Blood flow to the brain and heart are increased.
- Treat as Hypothermic Cardiac Arrest
40How will you manage hypothermia?
- Check for a pulse for at least 10 seconds
- Remove wet clothing
- Warm blankets
- Turn up heat in unit
- Prevent further loss of heat
41Associated Trauma
- Routine spinal motion restriction in submersion
emergencies is not recommended. - Applying SMR can delay opening the airway and
ventilating the patient.
42Spinal Injuries in Submersion Incidents
- Suspect spinal injury if
- Submersion has resulted from a diving mishap or
long fall. - Patient is unconscious.
- Patient complains of weakness, paralysis, or
numbness. - You suspect the possibility of spinal injury.
43Immobilization in Water
- Turn the patient into the supine position.
- Restore the airway and begin breaths if needed.
- Float a spine board under the patient and secure
the patient. - Remove the patient from the water.
44Immobilization in Water
45- Lets practice immobilization
- Practice in the water if you can.
46Transport
- Not all submersion victims suffer cardiac or
respiratory arrest. - Some victims are able to cough and clear their
airway, resuming normal ventilations on their
own. - All victims of drowning who require care by EMS,
even if they are alert and demonstrate adequate
breathing should be transported to the hospital
for evaluation.

53Case Study 1
- You respond with your department to a drowning at
a hotel. - On arrival you find a young adult male lying by
the pool with 2 adults performing CPR.
54Scene Size Up
- The scene is safe
- The hotel pool does not have a life guard.
- Hotel personnel report that bystanders found the
man at the bottom of the pool. - Hotel personnel say he could not have been there
for more than 10 minutes. - The hotel does not have an AED.
55Initial Assessment
- Airway water is in the airway
- Breathing the man is not breathing
- Circulation a faint slow pulse is found at a
rate of 30 beats/minute. - How do you want to proceed?
56- Does the patient need an AED at this point?
- If a submersion victim needs an AED what safety
precautions must be taken?
57SAMPLE History
- No one knows who the man is so no SAMPLE history
is available. - A hotel guest tells you that she thinks this man
was diving off the edge of the pool earlier. - How will this change your management of this
patient?
58- What else could have caused a submersion
emergency in a 20 year-old male? - Do you need to do any other treatment or can this
man be transported?
