“People are dying in Haiti because they can’t get out,” Dr. Green said.

It was not clear on Friday who exactly was responsible for the interruption of flights, or the chain of events that led to the decision. Sterling Ivey, a spokesman for Mr. Crist, said the governor’s request for federal help might have caused “confusion.”

“Florida stands ready to assist our neighbors in Haiti, but we need a plan of action and reimbursement for the care we are providing,” Mr. Ivey said.

Mr. Crist’s request did not indicate how much the medical care was costing the State of Florida, but the number and complexity of the cases could put the total in the millions of dollars. The expenditure comes at a time when the state is suffering economically and Mr. Crist, a Republican, is locked in a tough primary battle for the Senate seat that had been held by George LeMieux.

“Recently, we learned that plans were under way to move between 30 to 50 critically ill patients a day for an indefinite period of time,” Mr. Crist wrote in a letter to Kathleen Sebelius, the secretary of health and human services. “Florida does not have the capacity to support such an operation.”

A spokeswoman for the Department of Health and Human Services said the decision to suspend the flights was made by the military, not the federal health department. A military spokesman said that the military had ended the flights because hospitals were becoming unwilling to take patients.
