What are 4 life threatening conditions?

Four life-threatening conditions include heart attack, stroke, severe respiratory distress, and septic shock. A heart attack occurs when blood flow to the heart is blocked, while a stroke involves a disruption of blood flow to the brain, leading to potential brain damage. Severe respiratory distress can result from conditions like Asthma or pneumonia, impairing oxygen intake. Septic shock arises from a widespread infection leading to dangerously low blood pressure and organ failure.
