A 40-year-old trekking guide with 20 years of experience experienced a medical emergency while descending Aconcagua in Mendoza province, prompting an emergency response. The incident occurred near a region known as Cuesta Brava, close to the Plaza de Mulas campsite, where the guide suffered two consecutive seizures within 15 minutes, resulting in a rapid call for help. The emergency call was made around 12:30 PM when it was reported that the guide had lost consciousness.

The immediate response involved the local Rescue Patrol, park rangers, and medical personnel from the provincial park, who arrived quickly at the scene to provide assistance. Key to the successful evacuation was a skilled helicopter pilot who executed a complex maneuver to transport the guide from an elevation of 4,200 meters. The prompt actions by responders were crucial in ensuring the guide received necessary medical attention following his collapse during the trek.

This situation highlights the dangers associated with high-altitude trekking and the importance of having emergency protocols in place. As trekking becomes increasingly popular in the Aconcagua region, such incidents underline the need for adequate safety measures and the presence of experienced guides to ensure the safety of adventurers in challenging environments.
