When performing high-quality CPR on an adult, it is essential to ensure that the following actions are being accomplished:
- Chest Compressions:
- Depth: Compress the chest at least 2 inches (5 cm) but not more than 2.4 inches (6 cm).
- Rate: Perform compressions at a rate of 100 to 120 compressions per minute.
- Recoil: Allow complete chest recoil after each compression to let the heart refill with blood.
- Minimize Interruptions: Keep interruptions in chest compressions to less than 10 seconds.
- Ventilations:
- Ratio: If not using an advanced airway, use a compression-to-ventilation ratio of 30:2.
- Volume: Deliver each breath over 1 second, making the chest rise visibly.
- Avoid Excessive Ventilation: Provide just enough air to make the chest rise to avoid over-inflation of the lungs.
- Compression Technique:
- Hand Placement: Place the heel of one hand on the center of the chest (on the lower half of the breastbone), and place the other hand on top, interlocking fingers.
- Body Position: Position your shoulders directly over your hands and keep your arms straight to use your body weight for effective compressions.
- Team Dynamics:
- Communication: Clearly communicate with team members to ensure coordinated and effective resuscitation efforts.
- Role Assignment: Assign specific roles (compressor, ventilator, AED operator) and rotate compressors every 2 minutes to prevent fatigue.
- Use of AED:
- Prompt Application: Attach and use an Automated External Defibrillator (AED) as soon as it is available.
- Follow Instructions: Follow the AED prompts for analyzing the heart rhythm and delivering shocks if indicated.

Fats, also known as lipids, are a group of naturally occurring molecules that include triglycerides, phospholipids, and sterols. They are a major source of energy for the body and play several essential roles, including:
Types of Fats:
- Saturated Fats: Typically solid at room temperature and found in animal products like meat and dairy, as well as some plant oils like coconut and palm oil. High intake of saturated fats is associated with increased cholesterol levels and heart disease risk.
- Unsaturated Fats: Generally liquid at room temperature and found in plant-based oils, nuts, seeds, and fish. They are considered healthier for the heart and include:
- Monounsaturated Fats: Found in olive oil, avocados, and nuts.
- Polyunsaturated Fats: Found in sunflower oil, flaxseeds, and fish. This group includes essential fatty acids like omega-3 and omega-6, which are crucial for health and must be obtained through diet.
- Trans Fats: Artificially created through hydrogenation of vegetable oils and found in some processed foods. Trans fats are associated with increased risk of heart disease and should be minimized in the diet.

During post-cardiac arrest care, the recommended duration of targeted temperature management (TTM) after reaching the target temperature range (32-36°C or 89.6-96.8°F) is generally 24 hours.

During post-cardiac arrest care, the recommended duration of targeted temperature management (TTM) after reaching the target temperature range (32-36°C or 89.6-96.8°F) is generally 24 hours. This duration is based on guidelines and evidence supporting improved neurological outcomes and survival rates for patients who have experienced out-of-hospital cardiac arrest, particularly those with an initial rhythm of ventricular fibrillation or pulseless ventricular tachycardia.
After 24 hours of maintaining the target temperature, the patient should then undergo a gradual rewarming phase, typically at a rate of 0.25-0.5°C (0.45-0.9°F) per hour until they return to normothermia (37°C or 98.6°F).
It is essential to closely monitor and manage the patient’s physiological parameters throughout this process to minimize complications such as shivering, electrolyte imbalances, and hemodynamic instability.
