Shock: Cycle “A” Refresher
What is Shock?What is Shock?
Inadequate perfusion…
…What does this mean?
Lack of oxygen, other nutrients to body cells
The body needs oxygen to survive!

Blood PressureBlood Pressure
What brings oxygen to body tissues??Blood
What supports the delivery of blood??Blood Pressure

Shock: Cycle “A” Refresher
ShockShock
What is really happening in shock??
There is not enough blood pressure to adequately get oxygen to body tissues.

Shock: Cycle “A” Refresher
Compensated ShockTachycardiaTachypneaA narrowing of the difference between
the systolic and diastolic blood pressure (a.k.a - pulse pressure)
ShockShock
How do I identify that a patient is in shock??

ShockShock
How do I identify that a patient is in shock??
Decompensated ShockA drop in the systolic blood
pressure

Shock: Cycle “A” Refresher
ShockShock
Once the patient is in decompensated shock body cells begin to die.
This is a bad thing!!!!
Identify shock early before the patient has decompensated.

Shock: Cycle “A” Refresher
Types of ShockTypes of Shock
Hypovolemic:Hypovolemic: not enough volume
(e.g., bleeding, dehydration, vomiting, diarrhea)
Cardiogenic:Cardiogenic: not enough strength to push the volume
some causes of respiratory shock are actually cardiogenic shock (ex. Flash pulmonary edema from congestive heart failure)
![Page 10: Shock Nature’s prelude to death](https://reader035.vdocuments.site/reader035/viewer/2022062407/56812d7a550346895d928e6d/html5/thumbnails/10.jpg)
Shock: Cycle “A” Refresher
Types of ShockTypes of Shock
NeurogenicNeurogenic (a.k.a. - Distributive): loss of tone in the blood vessels
(e.g., sepsis, severe infection, anaphylaxis, spinal cord injury, psychogenic)
Other reasons for shock:Other reasons for shock:A mechanical obstruction that prevents movement of blood (a.k.a. – Obstructive)
some causes of respiratory shock are actually obstructive shock (ex. pulmonary embolism)

HemorrhageHemorrhage
A cause of hypovolemic shock
In trauma, hemorrhage most common cause of shock !!!!
Caution: It is not the only reason for shock in trauma, but is definitely the most common reason.

Diagnose shock early
Stop bleeding
Give oxygen
Keep patient warm(Hypothermia makes
shock worse)
