Artial bleeds
bright red, rich in oxygen, high pressure
Venous bleeds
dark red, low in oxygen
Capillary bleeds
slow and oozing, low in pressure
all different shocks
respiratory, neurogentic, cardiogentic, anaphlatic, metobolic, psychogentic (self recovery, fainting), septic (fever)
compensated state of shock
increase heart rate increase respiratory constriction of periphery
Decompensated state of shock
blood pressure falls
Irreversable state of shock
unable to maintain perfusion of vital organs cell damage occurs
hypovolemic shock
caused by uncontrollable bleeding or hemorrhage
cardiogenic shock
caused by myocardial infraction or heart attack
neurogentic shock
caused by uncontrolled dialation of blood vessels
rapid weak pressure (<40) decrease bp distended neck veins tracheal diviation decreased breath sounds uneven breath sounds
blood in lungs cough up blood
(chest crush) distended neck veins head, neck, shoulder are dark blue blood shoot eyes swollen toung and lips
Cardiac Tamponade
decreased heart sounds weak pulse decreased bp distended neck veins
internal organs out side of body
Burn agents
Chemical Electrical
Burn source
Ex. dry lime what time it was
1st degree Superfical
epidermis swelling red skin
2nd degree burns parital thickness
blistering, through dermis + epidermis intense pain
3rd degree Full thickness
all layers damaged including nerves severe pain from sorrounding 1st +2nd burns no pain where 3rd is
4th and 5th degree burns
4th- muscles 5th- bone
Rules of nines Rule of palm
each major area represents 9% of the body surface area patients palms are 1% of total body area
Adult rule of nine
18% back, chest, legs 9% each arm, head 1% groin
Child rule of nine
head: 12% chest: 18% back: 18% arms: 9% legs: 16.5% each groin: 1%
Infant rule of nine
Head: 18% arms: 9% Chest and Back: 18% Legs: 13.5% groin: 1%
Critical Burns
inhaling super heated >10% of full thickness >30% partial thickness burns on face, hands, feet, genitalia anywhere encircling a body part (all around chest)
Treatment for burns
moist sterile dressing for 1st or 2nd <10% dry sterile dressing for 2nd >10% or for 3rd degree
autonomic nervous system controlls
heart, breathing, diameter or vessels, sphincter muscles
get a bad headache and you go in and out of responsiveness
closed head injury bruising on opposite side of head bruising same side croup
collection of blood in tissue subdural epidural intra cerebral
subdural hematoma
bleeding between skull and protective covering of the brain
glasco coma scale
need more than 13 obey commands, localization of pain, pain withdraws, posturing in extension
spinal injury s+s
paralysis, pain w/out movement, pain with movement, tenderness around spine, impared breathing, deforrmity, priapaism (erection), posturing, loss of bowel, bladder, spinal shock, pins and needles
non displaced fracture
crack of the bone
displaced fracture
moved over fracture in which there is actual deformity
broken in multiple places
s+s of dislocation
marked deformity swelling pain tenderness on palpation ecchymossis is at site (delayed)
compartment syndrome:
elevated pressure with infascial compartment develps 6-12 hours after injury splint limb at heart level
Moderate injuries
open fractures of digits non displaced long bone fracture non displaced of pelvic fracture major sprain of major joint
Severe injuries
laceration of major nerves or blood vessels multipule digit amputations dislocations of major joints displaced pelvic fracture open long bone fractures multiple hand and foot fractures displaced long bone fracture
dont use traction splint if...
injuries close or involving knee pelvis or hip injury partial amputation or avulsion with bone seperation lower leg, foot or ankle injuries
acute injuries
clavical fractures ac sprains rib contusions and fractures shoulder dislocations
the build of blood produces a characteristics blue or black discoloration
blunt trauma to the eye can cause:
hyphema, retinal detachment, blowout fractures
bleeding into the anterior chamber of the eye, obscuring the iris
coughing up blood
pleuritic pain or pleurisy
irritation of damaged to the pleural surfaces causes a characteristic sharp or sticking pain with each breath when these normally smooth surfaces slide on one another
tension pneumothorax:
when there is significant on going air accummulation in the pleural space, collasping long and then pushing the medeastinum into opposite pleural cavity
traumatic asphyxia
the sudden increase intrathoracic pressure results: distended neck veins, cyanosis in face and neck, hemorohage into scera of the eye
hallow organs
stomach, intestines, uterus, and bladder these organ will spill their contents into the peritoneal cavity
pathologic fracture
a fracture of a weakened or disease bone
epiphyseal fracture:
a fracture that occurs in a growth section of a childs bone and may lead to abnormal growth in furture
cerebral edema
sweilling of the brain
can result in serious injury to internal organs distant to actual path of the bullet
Subcutaneous emphysema
the presence of air in the soft tissue produces a characteristic crackling sensation
