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% |
