After Hurricane Maria, some of Puerto Rico's hospitals went dark and lost power. 

"You got up that Wednesday morning and you found out Puerto Rico had zero electricity, it was zero electricity. Hospitals began an ordeal working with patients without any electrical grid," Jamie Pla Cortes, Puerto Rico Hospital Association said. 

The Puerto Rico Association of Hospitals says, out of the island's 69 hospitals, two are closed, another eight use generators to keep the doors open and their life-saving machines on. 

"The conditions of some of the areas have made it very difficult to restore electricity," Pla Cortes said. 

To ease the island's overwhelmed hospitals, a navy ship docked in old San Juan serves as floating hospital.

Because it's government-run. Commander Kim Lippes say, doctors treat patients at no cost. They've seen almost 5,000 people. 

"The patients are wonderful. They're very appreciate of our services. In some cases, they haven't seen services for a while. Anything we can to do make them feel better and support them," Lippes said. 

Even with the help, people are still suffering. More than half the island is without power and resources are in short supply.  

"Obviously if patients were on oxygen, they may have died in their homes or their situation may have worsened. But to pinpoint how many patients died because of Maria, it's very difficult to do that," Pla Cortes said. 

As the island continues its long road to recovery, the people in San Juan say, "Puerto Rico se la vante", which means the island will rise again.
