Study Notes
Shock Overview
- Shock is a life-threatening condition caused by inadequate tissue perfusion and impaired cellular metabolism.
- It leads to serious pathophysiological abnormalities due to oxygen and nutrient deficiencies.
Common Signs and Symptoms
- Blood pressure falls to 90 mm Hg systolic or lower, indicating possible shock.
- Victims exhibit tachycardia (rapid heartbeat) and tachypnea (rapid breathing).
- Low urine output suggests reduced kidney perfusion.
- Labored, irregular breathing can complicate the condition further.
- Peripheral pulses may be weak, thready, or absent, indicating poor circulation.
- Skin may appear ashy or cyanotic, indicating insufficient blood oxygenation.
- Body temperature may drop, signaling possible hypothermia.
- Mental status shows signs of decline, potentially leading to unresponsiveness.
- Pupils may become dilated, a neurological indicator of shock.
Complications
- Untreated shock can lead to irreversible cellular and tissue damage.
- Severe outcomes may include multiple system organ failure and death.
Emergency Response
- Call emergency services and provide clear directions.
- Assess the environment for safety, ensuring no further harm to the victim.
- Identify signs of the specific type of shock.
- If safe, place the victim in the recovery position.
- Check responsiveness, breathing, and manage severe bleeding.
- Be alert to vomiting; position the victim to prevent choking.
- Maintain normal body temperature using blankets or coats.
- Perform CPR if necessary and continue until professional help arrives.
- Avoid giving the victim food or drink and transport them to a medical facility.
Shock Prevention Strategies
- Hypovolemic Shock: Stay hydrated with water and nutrient-rich foods.
- Regular exercise promotes effective tissue perfusion.
Types of Shock
- Hypovolemic Shock: Caused by losing more than 20% of blood/fluid; requires immediate attention.
- Cardiogenic Shock: Results from heart ventricle dysfunction; low urine output may indicate inadequate blood flow.
- Neurogenic Shock: Manage through regular exercise for brain oxygenation and blood flow.
- Anaphylactic Shock: Know and avoid triggers; alert others about anaphylaxis and proper use of epinephrine.
- Septic Shock: Resulting from severe infections; common throughout various conditions.
Causes of Shock
- Severe bleeding and burns, heart failure, and heart attacks are primary causes.
- Head or spinal injuries, severe allergic reactions, dehydration, and electrocution are also significant factors.
- Emotional distress can trigger temporary shock but is less dangerous compared to physical causes.
Lifestyle Recommendations
- Prevent cardiogenic shock through non-smoking, maintaining healthy weight, and dietary adjustments to limit cholesterol and sugar.
- Regular check-ups aid in early detection and management of conditions that can lead to hypovolemic shock.
