General signs and symptoms of shock ✅-skin:pale, cool, diaphoretic
-anxiety
-impending doom

-tachypnea
-decreased urine output

-delayed capillary refill
General treatment in shock ✅-high flow oxygen
-trendelenberg position
-keep warm
-load and go transport
Cardiogenic shock ✅-most commingly caused by AMI
-other causes: Myocarditis, myocardial contusion
,-"pump problem"
-decreased CO leads to hyperfusion
-heart begins to fail
Cardiogenic shock treatment ✅-standard shock treatment applies
-patient may not tolerate supine or trendelenberg position
-transport to cardiac facility critical
Neurogenic shock ✅Circulatory failure caused by paralysis of the nerves that control
the size of the blood vessels, leading to widespread dilation; seen in patients with spinal

NPA (nasal trumpet) ✅-can use on patients with a gag reflex
-patients who are snoring or have ETOH are common
-measure from the nare to the tip of the earlobe
-use surgical lube to help with insertion
- right nare is usually largest
How to open airway ✅head tilt chin lift
-*do not perform on suspected c-spine injury
Jaw thrust maneuver
- *use if you suspect a neck injury and tilt head to slight sniffing position or neutral
position. Use thumbs to pull down lower jaw.
KED ✅Kendrick Extrication Device
-used to extricate patients in a sitting position when spinal injury is suspected
-do NOT use when patient is unstable-straps need to be applied in specific order:
Middle (yellow), Bottom (red), leg straps, headstraps, top (green)
