Distributive shock includes (3)
Neurogenic
Anaphylactic
Septic


4 stages of shock
Initiation/Initial

Compensatory

Progressive

Refractory/ Irreversible

, Initial stage clinical manifestations
Occurring on a cellular level- not clinically apparent


Durring the compensatory stage the body is....
Trying to maintain homeostasis (neural, biochemical, and hormonal activation)


Compensatory stage S/S (7)
Hypotension

Tachycardia

Restlessness

Anxious

Confused or AO4

Decreased GI motility

Skin pale or warm


Durring the compensatory stage BP may
normalize or be slightly high due to aldosterone secretion or effective
compensation- example: warm sepsis.


Activate of RASS durring the compensatory stage due to
Sodium and water retention


Durring the progressive stage the compensatory mechanism
Begins to fail
