3 Components required for perfusion | 1.Functioning Pump(The Heart)
2.Appropriately sized container(Vascular System)
3. Adequate circulating blood volume with red blood cells capable of carrying oxygen and removing wastes. |
5 Categories of Shock | 1.Hypovolemic
2.Distributive
3.Cardiogenic
4.Obstructive
5.Metabolic |
Define Shock | State of inadequate tissue perfusion with reduced amounts of oxygen and glucose being delivered to the bodys cells and tissue. |
3 Stages of Shock | 1.Compensated
2.Decompensated
3.Irreversible |
ABCDE of Shock | A. Airway
B. Breathing
C. Circulation
D. Assuring Adequate Oxygen
E. Achieving End Points. |
Normal End Points of Shock | Normal BP, Heart Rate, and Urine Output |
Define and example
Hypovolemic Shock | Due to Inadequate circulating blood volume. Trauma, GI Bleed, Ruptured AAA |
Define and example
Distributive Shock | Due to peripheral vasodilation and maldistribution of blood flow. Sepsis, Anaphylaxis, Spinal Cord Injury, Toxic Shock |
Define and example
Cardiogenic Shock | Due to inadequate cardiac pump function. AMI, Dysrhythmias, Overdose. |
Define and example
Obstructive Shock | due to non-cardiac obstruction to blood flow
Pulmonary Embolism, Cardiac Tamponade |
Metabolic Shock | due to toxic disruption of cellular function. CO, Hydrogen Cyanide and Sulfide Poisoning. |
Cardiac Output Calculation | CO=HR X SV Heart Rate X Stroke Volume |
Blood Pressure Calculation | BP = CO X SVR Cardiac Output X Systemic Vascular Resistance. SVR aka Afterload |
Stroke Volume | Amount of blood pumped with each contraction of left ventricle. |
In the setting of shock, what nervous system overrides the other nervous system. | Sympathetic. Increases heart rate and contractility and causes arterial vasoconstriction to maintain blood flow to vital organs. |
Urinary System Response in Shock. | Renin, Released from the kidneys and functions as an enzyme that converts angiotension. |
Endocrine System Response. | Glucagon, released from pancreas serves to increase blood glucose. |
Failure of two or more organs | Multiple System Organ Failure |
Positive test of Orthos. | Increase HR of 30 BPM or More
Decrease of systolic BP by 20 mmHg or more. |
Endpoint of Oxygen and ventilatory support. | Pulse Ox above 93-95% |
