- Definition: Combines assisted ventilations and chest compressions to artificially replicate the functions of the lungs and heart.
- Purpose: Increases survival chances by keeping the body supplied with oxygen until advanced medical care is available.
- Components: Consists of cycles of compressions and ventilations.
- Basic Ratio: 30 compressions to 2 ventilations (may vary based on age and number of responders).
- CPR Execution:
- Uninterrupted process: Once CPR starts, it should only be interrupted for critical interventions or changes in the patient's condition.
- Chest Compressions:
- Purpose: Move blood through the circulatory system by creating pressure within the chest cavity.
- Compression fraction: The percentage of total CPR time the patient receives compressions.
- Hand position: Center of the chest, lower half of the sternum.
- Interlock hands and maintain right angles with pressure going straight downwards.
- Responder position: Kneeling beside and facing the patient.
- Arms straight, shoulders above elbows, elbows above hands.
- Use upper body weight to create the necessary force.
- Chest recoil: Ensure complete chest recoil after each compression.
- Compression depth:
- Adults: 5-6 cm (2-2.4 inches).
- Children/Infants: At least one-third the diameter of the chest.
- Compression rate: 100-120 compressions per minute.
- Age-Specific Guidelines:
- Adults:
- Hands position: Two hands on the sternum.
- Compression depth: 5-6 cm.
- Ratio: 30 compressions to 2 ventilations.
- Children:
- Hands position: One or two hands on the sternum (based on size).
- Compression depth: One-third chest depth.
- Ratio: 30:2 (one responder), 15:2 (two responders).
- Infants:
- Hands position: Two fingers on the sternum or thumbs using the encircling method.
- Compression depth: One-third chest depth.
- Ratio: 30:2 (one responder), 15:2 (two responders).
- Adults:
- High-Performance CPR (Team Approach):
- Feedback: Responder B provides feedback on the effectiveness of Responder A's compressions.
- Role distribution:
- Responder A: Starts CPR, performs chest compressions, and ventilates using BVM until Responder B returns.
- Responder B: Retrieves defibrillator (AED), assists with airway management, and ensures proper BVM seal.
- Position switching: Every 2 minutes or 5 cycles, switch roles to maintain effectiveness and reduce fatigue.
Automated External Defibrillators (AEDs)
- Deployment: Apply AED as soon as cardiac arrest is confirmed, aiming for deployment within 90-120 seconds.
- Placement:
- Adults: Standard placement.
- Children/Infants: Use adult pads on the front and back if pediatric pads are unavailable.
- Preparation:
- Ensure patient is dry.
- Remove excessive hair for good contact.
- Operation:
- Attach pads, plug in, turn on AED.
- Follow AED instructions, pausing CPR only during analysis.
- Resume CPR immediately after shock delivery.
Shock
- Definition: A life-threatening condition where vital organs do not receive adequate oxygen-rich blood, leading to compromised functionality.
- Causes of Shock:
- Cardiogenic Shock: Heart is not functioning effectively, causing inadequate blood circulation.
- Hypovolemic Shock: There is too little blood volume circulating.
- Distributive Shock: Blood vessels fail to constrict properly, causing a drop in blood pressure even though blood volume remains unchanged.
- Types of Shock:
- Septic Shock: A form of distributive shock due to severe infection.
- Hypovolemic Shock: Caused by significant blood loss.
- Obstructive Shock: Physical blockage prevents the heart from filling or emptying effectively.
- Neurogenic Shock: A form of distributive shock from loss of nervous system control over blood vessel constriction.
- Anaphylactic Shock: A severe allergic reaction causing hypovolemic shock.
- Stages of Shock:
- Compensated Shock: The body attempts to restore normal circulation by constricting blood vessels.
- Decompensated Shock: The body's compensation fails, leading to hypoxia in tissues.
- Irreversible Shock: The vascular system fails to maintain internal pressure, blood pools in the extremities, and survival is not possible despite intervention.
- Care for Shock:
- ABCs: Ensure the airway is clear, breathing is adequate, and circulation is supported.
- Positioning: Help the patient into a recovery or supine position to improve blood flow to vital organs.
- Elevation: Elevate the patient's feet about 8-12 inches unless a head injury is suspected.
- Temperature Maintenance: Keep the patient warm to maintain normal body temperature.
- Avoid Eating or Drinking: Do not give anything to eat or drink, especially if the patient's level of responsiveness is affected.
