Q

Perfusion

A

blood circulation, helps meet cell needs for proper functioning, systemic (between heart and body) and pulmonary (between heart and lungs), needs blood & oxygen

A

heart not functioning/pump failure, extra blood backed up into pulmonary vessels, can cause pulmonary edema

Q

Tension Pneumothorax

A

air in chest cavity outside of lung, lung collapses (pneumothorax), can prevent vena cava from fully expanding, less returning blood press, cause obstructive shock

16
Q

Pulmonary Embolism

A

blood clot in pulmonary vessels, causes heart pump failure, clot develops in body but moves to lungs, can use blood thinners, cause obstructive shock

17
Q

Deep Vein Thrombrosis

A

blood clot developed in calf, moves to lungs and causes pulmonary embolism

18
Q

Distributive Shock

A

caused by dilation of small arterioles, blood pools in vascular beds of lungs

19
Q

Septic Shock

A

severe infection of vessel wall, blood leaks out and pool in alveoli

20
Q

Neurogenic Shock

A

damage to upper spinal cord, unable to control vessels under injury location, vessels dilate, blood pools

21
Q

Anaphylactic Shock

A

severe allergic reaction, response to substance previously sensitized to, hives (urticaria) cyanosis etc.

22
Q

Cyanosis

A

skin turns blue

23
Q

Psychogenic Shock

A

sudden reaction, blood vessel dilate, temporary

24
Q

Syncope

A

fainting episode

25
Q

Aneurysm

A

swelling of blood vessel in brain

26
Q

Hypovolemic Shock

A

lack of fluid in circulatory system, ie. dehydration, vomiting, bleeding out, burns

27
Q

Compensated Shock

A

early stage of shock, normal or high blood pressure, RR & HR, anxiety, feeling of impending doom, weak pulse, clammy, cyanosis, nausea, decreasing pulse pressure

28
Q

Decompensated Shock

A

late stage of shock, BP falling, irregular breathing, body failing, impending doom, altered consciousness, dull eyes

29
Q

Irreversible Shock

A

unable to resuscitate patient afterwards

30
Q

Shock Assessment

A

pt 1: assess consciousness, spinal stabilization, and airway, determine shock/stage of shock
pt 2: if there’s time, identify trauma injury, if there’s problems with primary assessment, get vital signs

31
Q

Treating Cardiogenic Shock

A

give pain medication for chest pain, DO NOT GIVE IF hypotensive or if taking sex enhancement drugs (drops blood pressure too much)

32
Q

Treating Cardiac Tamponade

A

high flow oxygen, increase pressure in pericardium and preload, needs surgery

33
Q

Treating Tension Pneumothorax

A

non rebreathing mask, decompress injured side of chest, needs ALS

34
Q

Treating Septic Shock

A

transport asap, use high flow oxygen, ventilation support, use blankets, contact hospital

35
Q

Treating Neurogenic Shock

A

spinal stabilization, maintain airway, supply oxygen/breathing if needed, keep warm with blankets, transport

36
Q

Treating Anaphylactic Shock

A

use epipen, transport to ED, determine the cause of allergic reaction

37
Q

Treating Psychogenic Shock

A

keep in supine position, check for injuries, transport to ED, record vitals

38
Q

Treating Hypovolemic Shock

A

control external bleeding via pressure, secure airway, give respiratory support/oxygen, make sure patient doesn’t aspirate of vomit, transport asap
