Study Notes
Shock: Primary Failure Characteristic
- Insufficient oxygen-rich blood flow to vital organs due to cardiovascular system failure.
Conditions Least Likely to Cause Shock
- Tender abdomen.
Signs NOT Commonly Associated with Shock
- Nausea and vomiting.
Prioritized Action in Shock Treatment
- Maintaining an open airway and controlling bleeding.
Airway Opening with Suspected Spinal Injury
- Method not specified in provided text.
Recommended Leg Elevation in Shock
- Lower extremity elevation is contraindicated with suspected head or spinal injuries. No specific elevation angle is provided otherwise.
Late-Stage Shock Symptom
- Weak and absent pulse (implied to be a later symptom)
Treatment for Shock with Head/Spinal Injuries
- Do not elevate lower extremities.
Additional Notes on Shock
- Shock signs can be masked by other conditions.
- All classic shock signs may not be immediately present.
Shock: Definition and Causes
- Shock is the circulatory system's failure to deliver enough oxygen-rich blood to vital organs.
- Conditions like uncontrolled bleeding, abdominal injury, pelvic instability, femur fractures, and severe allergic reactions can rapidly lead to shock.
- MARCH interventions often result in shock.
- Shock can cause a drop in core body temperature. Assume any patient may develop shock.
Shock: Signs and Symptoms
- Recognizing early signs is crucial for timely intervention.
- Not all signs will be present in every patient.
- Symptoms may be delayed or masked by other injuries/illnesses.
- Potential signs and symptoms include: anxiety, restlessness, fainting; altered mental state (excluding head injuries); nausea and vomiting; excessive thirst; vacant, dull eyes with dilated pupils; shallow, rapid, or irregular breathing; pale, cool, or clammy skin; and weak, rapid, or absent pulse.
Shock: Treatment
- Prioritize life-threatening issues first (e.g., severe bleeding, allergic reactions).
- Maintain an open airway using head tilt-chin lift (unless spinal injury suspected, then use jaw thrust).
- Elevate lower extremities 6–12 inches (unless head, neck, spinal, or pelvic injuries are suspected).
