Chapter 13- Shock Flashcards
emergency care
maintain supine position
provide oxygen
give pt blankets
transport and treat additional injuries en route
symptoms of compensated shock
weak, rapid pulse
cool, clammy skin
cyanosis around lips
pale
shallow, rapid breathing
nausea/vomiting
slow capillary refill
symptoms of decompensated shock
falling BP
altered LOC
labored or irregular breathing
ashen, mottled, or cyanotic skin
thready or absent peripheral pulses
dull eyes, dilated pupils
compensated shock
early stage, body can still compensate for blood loss
decompensated shock
late stage shock, when BP is falling
hypovolemic shock
caused by an inadequate amount of fluid or volume in the circulatory system
results of psychogenic shock
vascular dilation
fainting
irregular heartbeat
late sign of anaphylactic shock
cyanosis
neurogenic shock
results from a high spinal cord injury
signs of neurogenic shock
Absence of sweating below level of injury
Low HR with hypotension
Normal warm skin
bradychardia
signs of a neck injury
5 kinds of distributive shock
septic shock
neurogenic shock
anaphylactic shock
psychogenic shock
hypovolemic shock
pulmonary embolism
a blood clot that blocks flow of blood to pulmonary vessels
can prevent blood from being pumped to the right side of the heart to the left
tension pneumothorax
when the air of a pneumothorax shifts the organs toward uninjured side of chest
symptoms of tension pneumothorax
drop in BP
anxiety
shortness of breath
HR and respiratory rate increase and become shallower
increased or absent lung sounds on affected side
cyanosis
late sign = tracheal deviation
cardiac tamponade
when blood leaks into the space between the pericardium (sac around heart) and the pericardial sac
pericardial effusion
collection of fluid between the pericardial sac and the myocardium (muscular tissue of heart)
signs of obstructive shock
JVD
muffled heart sounds
dropping systolic BP with rising diastolic
cardiogenic shock
Caused by inadequate function of heart or pump failure
edema
presence of abnormally large amounts of fluid between cells in body tissues, causing swelling
pulse pressure equation
systolic - diastolic
symptoms fo septic shock
warm skin or fever
tachycardia
low BP
symptoms of hypovolemic shock
rapid, weak pulse
low BP
change in mental status
cyanosis
cool, clammy skin
increased respiratory rate
