09 CAC Shock

Chapter 13, The Paramedic by Will Chapleau

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%
