Final answer:
The 6 "H"s reversible causes of cardiac arrest are: hypovolemia, hypoxia, hydrogen ion (acidosis), hypo-/hyperkalemia, hypothermia, and tension pneumothorax.
Step-by-step explanation:
The 6 "H"s reversible causes of cardiac arrest are:
- Hypovolemia: This refers to a decrease in blood volume, which can occur due to severe bleeding or dehydration.
- Hypoxia: This is a condition where there is a decrease in the oxygen supply to the body's tissues, which can happen due to respiratory failure, choking, or drowning.
- Hydrogen ion (acidosis): Acidosis is a condition where the pH level of the blood becomes too acidic. It can occur due to conditions like diabetic ketoacidosis or kidney failure.
- Hypo-/Hyperkalemia: This refers to abnormal levels of potassium in the blood. Hypokalemia is a low potassium level and hyperkalemia is a high potassium level. Both can disrupt the normal electrical activity of the heart.
- Hypothermia: This is a condition in which the body's temperature drops below normal. It can be caused by exposure to cold environments or certain medical conditions.
- Tension pneumothorax: This is a condition in which air accumulates in the pleural space, causing pressure on the lungs and heart. It can happen due to lung injury or certain medical procedures.
