Q

Stages of Shock

A
  1. Compensated Shock
  2. Decompensated Shock
  3. Irreversible Shock
50
Q

Types of Shock

A
  1. Hypovolemic
  2. Obstructive Shock
  3. Cardiogenic Shock
  4. Distributive Shock
51
Q

Hypovolemic Shock

A

Etiology/Pathology:
Hemorrhage / Whole-blood loss
Burns / Plasmas loss, fluid shifts`

52
Q

Obstructive Shock

A

Etiology / Pathology:

  • Cardiac tamponade / Compression of heart w/obstruction to atrial filling
  • Tension pneumothorax / Mediastinal shift w/obstruction to atrial filling
  • Tension hemothorax /combination of compression of the heart and mediastinal shift
53
Q

Cardiogenic Shock

A

Etiology / Pathology:

  • Myocardial infarction / loss of cardiac contractility
  • Dysrhythmias / Reduced CO
  • Blunt cardiac trauma / Loss of cardiac contractility and dysrhythmias
54
Q

Distributive Shock

A

Etiology/Pathology:

  • Spinal Cord Injury (Neurogenic shock) / loss of vaso -motor tone due to decreases in sympathetic control
  • Sepsis / mediated by sstemic inflammatory resonse syndrome with hypotension and perfusion abnormalities
  • Anaphylaxis / vasodilation of vessels due to immune reaction to allergens (release of histamine)
55
Q

Cerbral Perfusion Pressure (CPP)

A

60-100 mmHg

56
Q

Mean Arterial Pressure (MAP)

A

50-150 mmHg

57
Q

Intracranial Pressure (ICP)

A

Normal is 0-15 mmHg

58
Q

Effects of CO2 on Vasculature?

A 
High CO2 (hypoventilation) = thin dilated vessels
Low CO2 (hyperventilation) = thickened narrow vessels
59
Q

Effects of CO2 on Vasculature?
