Index of Suspicion

Awareness that life threatening injuries may exist.

Types of Energy & Injuries

Potential-Could do
Work-Force it requires

Velocity or Size



ejection, partial, head compression, spinal injury


lateral whiplash, shoulder/thorax/upper xtremities/skull into door, w/ intrusion-chest, abdomen, lower xtremities, pelvis, ribs injuries

Rear End

Whiplash, head, spine injuries. Back seat w/ lap-thoracic & lumbar

Signs of Hi Energy Impact in Vehicular Collision

Vehicle deformity
Altered Mental Status

Unrestrained Passenger vs. Restrained

Shoulder only-lower xtremities/pelvis injuries
Seatbelts too low-hip dislocation
Too hi-abdominal injuries
No seatbelt-abrasions from air bag, frontal-knees, femur, pelvis & hip injuries. Chest, abdominal injuries, head too

Purpose of Airbags

Decrease severity of deceleration injuries by allowing seatbelts to be more compliant and by gently cushioning

What vehicle collision can cause an Aortic injury


How to asses MOI of Car vs. Person

Estimate speed, thrown?, distance thrown?, struck?, pulled, structural damage

Factors for MOI from a Fall

Fall >15' or 3 times patients height
surface struck
part of body that hit first
injuries to lower xtremities, pelvic and spine when landing on feet
head and spine when landing on head

Hi/Med Energy Penetrating Injuries

Damage can be many times larger than wound.

Lo Energy Penetrating Injures

caused by sharp edges, knives, unseen damage

Clotting Process

Blood flows rapidly to cut, cut ends of vessels begin to narrow, clot plugs hole. Takes about 10 minutes.

Apoxia Timeframe for Organs

Heart-Constant perfusion
Brain/Spinal Cord-injury after 4-6 minutes
Kidneys-After 45 minutes
skeletal muscle- after 2 hours
GT-slightly longer
cold will delay


AKA Shock. System fails to provide sufficient circulation for every body part to perform its function

How much blood loss can the body tolerate

Will not toletate an acute blood loss of >20% of blood volume. ex. 175 lb man=2 pints (1L)
symptoms: increased hrt/resp rates, decreasing blood pressure
ex. 800 ml infant=100-200mL

What effects clotting

Movement, medications, removal of bandages, external environment, body tmeperature, partial vessel wall

How to treat a nosebleed

Epistaxis. Have patient lean forward. Head forward. Direct pressure to fleshly part of nose for 15 minutes.

What happens when core receives poor perfusion

Damage to organ tissue, dysfuntion, failure and eventually death to organism

Signs of Compensated Shock

Early stage of shock when the body can still compensate for blood loss

Signs of Decompensated Shock

Define Pleurisy

(also known as pleuritis) is an inflammation of the pleura, the lining of the pleural cavity surrounding the lungs.

Chest injuries

broken ribs-insufficient O2
Bruised heart-irregular heart beat
torn vessels-internal bleeding
bruised lungs-insufficient O2
Air in lung tissue/chest wall-insufficient O2 (pneumothorax)
blood in lung/chest-hemothorax
open chest wound

Pneumothorax-Symptoms & Treatment, and when

partial or complete accumulation of air in the pleural space

Tension Pneumothorax

life threatening collection of air w/i the plural space; the vol. and pressure have both collasped the involved lung and cause a shift of the mediastinal structures to the opposite side

break in the continuity of the bone

Connective Tissues


Types of Fractures



grating/grinding sensation cause by fractured bone ends or joints rubbing together

Severity of Fractures


Why ice/elevate extremities


Traction Splints


Treating Dislocations


Cerebrum Function

control movement, hearing, balance, speech, visual perception, emotions, and personality.

Cerebellum Function

coordinates the various activities of the brain, particularly fine body movements

Brain Stem Function

breathing, temperature control, heartbeat and blood pressure


3 distinct layers of tissue that surround and protect the brain and spinal cord w/i the skull and the spinal canal


aka bruises


temp loss or alteration of part or all of the brain's ab ilities to function w/o actual physical damage to the brain.

Intercranial Bleeding


Subdural Bleeding


Ways to damage the spine


Symptoms of Head Injuries

confusion, seizures, vomiting, difficulty concentrating, increased mood swings, lethargy or aggression

Treatment for head injuries


Helmet removal


Proper Size C-Collar

same as vs. pedestrian + damage to bicycle and location of, helmet, spinal injuries until proven otherwise.
