09 CAC Shock
Chapter 13, The Paramedic by Will Chapleau
| Question | Answer |
|---|---|
| Regardless of cause of shock what is the primary goal? | Preserve Airway, Breathing, Circulation; appropriate resuscitation measures, and transport the patient quickly. |
| Regardless of cause of shock what are the primary goals? | Preserve Airway, Breathing, Circulation, Appropriate Resuscitation Measures, and transport the patient quickly. |
| 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% |
