18
Q

what are the symptoms of atherosclerosis

A

symptoms for atherosclerosis develop gradually and may not show until the arteries are significantly narrowed or blocked.
-chest pain

19
Q

what is cardiogenic shock

A

a life threatening medic condition where the heart suddenly cannot pump enough blood to meet the body’s needs.

20
Q

what can cardiogenic shock lead to

A

cardiogenic shock causes insufficient blood flow which leads to decreased oxygen delivery to tissues and organs, which can lead o organ failure if not treated properly.

21
Q

what are the causes of cardiogenic shock

A

-myocardinal infraction (heart attack)
-severe heart failure
-arrhythmias
-valvular heart disease
-cardiomyopathies
-myocarditis
-cardiac tamponade

22
Q

what are the symptoms of cardiogenic shock

A

rapid breathing
weak or rapid pulse
low blood pressure
cold, clammy skin
confusion
chest pain
loss of consciousness
decreased urine output

23
Q

what happens with RR, HR, SPO2,BP,CRT,Temp and Mental Status

A

RR-up and down
HR- up and down
SP02- down
BP-down
CRT- up and down
