pnuemothorax is...
air collecting between the lung tissue and the chest wall
Tourniquets are rarely used as a last resort.
A tourniguet is useful is a pt. is bleeding severly from a_______ or _____amputation
partial or complete
The first s/sx of hypovolemic schock is...
decreased mental status, such as anxiet restlessness or combativeness
** in non-trauma pts. weakness,faintness,dizzieness
Late s/sx of hypoperfusion shock suggesting internal bleeding
cold,moist clammy skin
shallow rapid breathing
dull eyes
low bp
weak, rapid, thready pulse
dilated pupils
infant peds with cap refill >2sec
s/sx of serious internal bleeding are
vomitting blood (hematemesis)
black tarry stools (melena)
coughing up blood (hemoptysis)
distended abdoment
broken ribs
3 basic causes of shock
Pump failure
low blood volume
blood vessel dilate excessively
Hypovolemic Shock caused by hemmorghe is called
hemorrhagic shock
Hypovolemic shock
shock caused by fluid or blood loss
Septic Shock
Shock caused by sever infection, usually bacterial infection.
*toxins damage vessel walls, causing a leak out of the vessels
what is a late sign of anaphalytic shock
neurogenic shock is described as
circulatory failure, leads to widespread dilation, seen in spinal cord injuries
Symptoms of nuerogenic shock
absense of sweating below level of injury dilated vessels, loss of body temp (hypothermia)
nuerogenic shock is the only type of shock that causes this
slow pulse (brachycardia)
Compensated shock is described as this
early stage body can still compensate for blood loss
Decompensated shock is described as this
the late stage of shock when pressure is falling
You should "expect" shock if a patient has any one of the 6 conditions
Multiple severe fx
adb or chest injury
severe infections
major heart attack
Signs when a pt. is in decompensated shock (late stage)
low bp
labored/irreg breathing
cyanotic skin
thready absent, perifpheral pulse
dilated pupils
poor urinary output
anaphayltic shock is described as
a person reacting violently to a substance that he/she has been sensitized
Never remove a impaled object
A systolic BP less that 100 mg Hg with weak rapid pusle should suggest...
shock/ hypoperfusion if accomipanied with bleeding
Perfusion shock is indicated by this
cool,moist, pale or gray skin
Cardiogenic shock is described as
inadequate funtion of the heart (develops when the heart muscle cant generate enough pressure to circulate blood to all organs)
* back up blood from cardiogenic shock in the lungs causes pulmonary edema
Mycoardial infarction
when a blood clot prevents blood flow to an area of the heart muscle
**infarction means death of a tissue
phneumothorax is..
an accumulation of air or gas in the plueral cavity
a bruise of the heart muscle is
mycardial contusion
the most severe form of blunt chest injury causing fx of 3 or more ribs each in 2 spaces
flail chest
collection of air under steadily increasing pressure in the plueral space
tension pnuemothorax
a collection of blood in the plueral cavity
index of suspicion
that unseen life-threating injuries may exsist
