Advanced Life Support (ALS) refers to a set of medical procedures and techniques used to treat patients experiencing life-threatening conditions. This includes managing cardiac arrest, severe respiratory issues, and other critical emergencies. ALS is typically performed by trained healthcare professionals, such as paramedics and emergency medical technicians, who use specialized equipment and medications to stabilize patients. The goal of ALS is to restore normal body functions and prevent further deterioration. Techniques may include intubation to secure the airway, administering intravenous fluids, and using defibrillators to correct abnormal heart rhythms. Quick and effective ALS can significantly improve a patient's chances of survival.
