Final answer:
Asystole and PEA can be caused by various reversible factors such as decreased oxygen supply, low blood volume, high potassium levels, drug overdose, and more.
Step-by-step explanation:
Asystole and PEA are two life-threatening cardiac rhythms that can result in cardiac arrest. There are several potential reversible causes of asystole and PEA, including:
- Hypoxia: Decreased oxygen supply to the heart.
- Hypovolemia: Decreased blood volume.
- Hypothermia: Low body temperature.
- Hyperkalemia: High levels of potassium in the blood.
- Toxic/Drug overdose: Excessive drug or toxin ingestion.
- Tension pneumothorax: Air accumulation in the chest cavity, placing pressure on the heart.
- Tamponade (cardiac): Fluid accumulation in the pericardial sac, compressing the heart.
- Thrombosis (pulmonary): Blood clot in the pulmonary vasculature.
- Thrombosis (coronary): Blood clot in the coronary arteries.
- Trauma: Physical injury to the heart.
