Dr. Art Chasen, trauma medical director at Maui Memorial Medical Center, described to ABC News what it’s been like treating patients who have been injured by the devastating wildfires.

He said Tuesday night was the first night he experienced a mass casualty event in the 12 years since he has worked at the hospital. Staff saw about 40 patients throughout the night, eight with life-threatening severe burns and the rest with minor burns, smoke inhalation injuries and other fire-related injuries.

Chasen described one patient, a fireman, who got seriously injured while trying to save people from a burning structure.

“He just kept going back until he ran out of oxygen,” Chasen said. “He ended up somehow taking off his mask and collapsing in the fire. His fellow firefighters went in and rescued him. He had severe burns on his legs at the scene.”

“He coded, his heart hard stopped and so he received CPR for three to five minutes…and they brought him back and he was in our ICU overnight.”

The fireman was transferred to Queen’s Medical Center in Oahu. In total, nine patients were transferred to Queen’s and Straub Medical Center, also in Oahu.

Maui Memorial has seen about 60 patients total as of Friday morning, and Chasen expects a second wave of injured patients now that roads are reopening, but insisted that the hospital is not overwhelmed or struggling to accommodate patients.

“We were not overwhelmed. We’ve never turned anybody away,” he said. “We have beds available. We have ICU space available. We’ve been seeing regular trauma patients throughout the time, like motorcycle accidents and things like that. So our hospital surged to meet the demand.”
