Blood transfusions are “always a consideration for trauma patients,” said Dr. Nicholas Namais, a University of Miami doctor and medical director of Ryder Trauma Center at Jackson Memorial Hospital that received 13 patients from the tragedy.

“Jackson Memorial is 100 percent respectful of patients’ wishes,” Namais said, describing steps doctors could take to decrease the demand for donor blood, including sedating them to reduce the demand for oxygen in the blood. .

He applauded the teamwork of the trauma surgeons, nurses, anesthesiologists and radiology technicians who followed the protocol designed to move the most critically injured patients into care quickly.

Late Tuesday, two patients remained in critical condition and three in stable condition.

Miami-Dade Police are still investigating the circumstances of the crash. No charges have been filed, a police spokesperson said Tuesday.

Lopez said he thinks the evidence suggests the bus was going much faster than 20 mph , as originally reported, because the “debris field” of shattered fiberglass and twisted metal extended 60 to 70 feet in front of the bus and 40 feet behind it.

“You don’t take 16 feet off the front of a bus when you’re going 20 mph,” Lopez said.

Lopez, whose job includes keeping traffic moving through arrivals and departures concourses, said people often accidentally end up at the airport. The driver of the bus was lost, according to investigators and passengers.

“I joke with my wife that everyone who gets lost in Miami ends up at the airport,” he said. “If someone’s not familiar they get panicky…The airport is an overwhelming place.”
