The governor's office said Tuesday "the facility reported to the AHCA [Agency for Health Care Administration] that they had power and access to fans and spot coolers".
According to BBC, ten million people are still without power in Florida, Georgia and the Carolinas after Hurricane Irma.
The storm - which has claimed more than two dozen lives in the USA and almost 40 in Caribbean - struck southwestern Florida on Sunday morning (Sep 10) as a category four hurricane before weakening to a tropical depression on Monday (Sep 11).
Officials in Hollywood, Florida, said eight elderly people living at a nursing home died after Hurricane Irma knocked out power, leaving them with no air conditioning.
"It's a sad state of affairs", Sanchez said.
He added that the patients who have been admitted to the hospital are mostly being treated for "respiratory distress, dehydration and heat-related issues". He said Broward County did not list the facility as critical infrastructure - the places where restoring power is a top priority after a storm - in a hurricane planning meeting earlier this year.
The association said it was working with officials to prioritise "the locations with the greatest need".
"A portion of the facility did, in fact, have power, that there was a hospital across the parking lot from this facility and that the nursing home was required to have a permanently installed operational generator", the power company spokesman Richard Beltran told CNN. As of 2016, Florida had about 680 nursing homes.
Calls to the owner and other officials at the Hollywood home were not immediately returned, but the facility's administrator, Jorge Caballo, said in a statement that it was "cooperating fully with relevant authorities to investigate the circumstances that led to this unfortunate and tragic outcome".
Ahead of its arrival, the hurricane triggered mass evacuations, with more than 6 million in Florida and neighboring states asked to flee.
The long-time retirement destination has the highest proportion of people 65 and older of any state.
One of the most powerful Atlantic storms on record, Irma bore down on the Caribbean with devastating force as it raked the northern shore of Cuba last week before barreling into the Florida Keys island chain on Sunday, packing sustained winds of up to 215 kph. "So I hope he runs for the Senate", Trump said. The records show that a year ago, the home had only a temporary generator, and was unable to produce documentation confirming its plans to replace it with a permanent one.
Police said they have opened a probe into possible criminal negligence. Utility officials warned it could take a week or more for all areas to be back up and running.
"The loss of these individuals is a profound tragedy within the larger tragedy of Hurricane Irma, and we extend our deepest sympathies to the families of these residents", Knapp said. One of them was later evacuated because of the heat.
