Causes of Shock
- 1. Pump Failure
- Cardiogenic Shock
- Obstructive Shock
- 2. Poor Vessel Function
- Distributive Shock
- 3. Low Fluid Volume
- Hypovolemic Shock
Types of Pump Failure Shock
- 1. Cardiogenic-Inadequate heart function, Disease of muscle tissue, impaired electrical system, Disease or injury.
- Would Present w/ Chest Pain, Irregular Pulse, Low BP, Cyanosis, Cool Clammy Skin, ETC.
2. Obstructive- Mechanical obstruction of the cardiac muscle (Tension Pneumothorax or Cardiac Tamponade) Would Present-Dyspnea, Rapid weak pulse, JVD, ETC
Types of Poor Vessel Function Shock
1. Septic- Severe bacterial infection. Would present with-Warm Skin, Tachycardia, Low BP
2. Neurogenic- Damaged C-Spine which causes wide-spread blood vessel dilation. Would Present With-Bradycardia, low BP, Signs of neck injury
3. Anaphylactic- Extreme life-threatening allergic reaction. Would Present With-mild itching or rash, buring skin, vascular dilation, generalized edema, coma, rapid death.
4. Psychogenic- Temporary generalized vascular dilation, anxiety, bad news, sight of injury or blood, severe pain, illness. Would Present With- Rapid Pulse, Normal to low BP
Types of Low Fluid Volume Shock
1. Hypovolemic- Loss of blood or fluid. Would Present With- Rapid weak pulse, Low BP, Change in mental status, cool clammy skin, increased RR.
2. Respiratory Insufficiency- Severe chest injury, airway obstruction. Would Present With- Rapid weak pulse, low BP, Change in mental status, cool clammy skin, increased RR.
What is the Progression of Shock
1. Compensated Shock-When the body can still compensate for blood loss. Presents with: Agitation, anxiety, feeling of impending doom, clammy pale skin, nausea or vomiting, ETC.
2. Decompensated Shock- The late stage when BP is falling. 90mm Hg below in adults, labored/irregular breathing, cyanotic skin, thready absent pulses, poor urinary output.
3. Irreversible Shock- This is the last stage, the terminal stage where nothing will help.
What is Shock?
Shock results from the body's maintenance of homeostasis.
