She recalled the words of the hospital staff: "Just push and pray, push and pray."
Later Tuesday night, she gave birth to a healthy, 2.4-kilogram baby named James Lyndon.
Carabana was one of five young mothers who have delivered in Calape since the quake hit Bohol Island.
Another expectant mother whose house was destroyed had to walk down a mountain to seek help from her relative before finding a ride to the hospital in Calape, said Meneleo Guibao, a nurse who is also the administrator of the 12-bed municipal hospital in the town.
On the way, along bumpy roads torn open by the quake, the woman's water burst, he said.
The baby came out not breathing and had to be resuscitated, Guibao said. Both the mother and baby were sent to a larger hospital in the provincial capital Tagbilaran, which was better equipped for emergencies. There was no word about their condition.
"Our theory is that she was trying to stop the baby from coming out because it was difficult traveling to the hospital," Guibao said.
The three other mothers and their babies were all doing fine and two of them were about to be discharged, he said.
Although not a stranger to disasters in a country that is often buffeted by typhoons, floods and shaken by volcanos and quakes, Guibao said that delivering babies in a tent amid aftershocks was a first for him.
"I have experience in home delivery, but I have not delivered under this calamity situation," he said.
Guibao said he worried about his patients, but was grateful for caregivers and volunteers who were aiding him and the rest of the staff.
Calape Mayor Sulpicio Yu said that almost 90 per cent of the buildings in his town, with a population of 32,000, were partially or totally damaged. At least five people were killed in Calape.
The hospital did not collapse, Guibao said, but there was no electricity and engineers had to check the building for damage before it was declared safe again.
Altogether 11 hospitals across the region were damaged by the quake, two seriously.
The Health Department said that doctors were waiting for helicopters or boats to transfer 60 patients needing surgery or critical care to Tagbilaran from Loon, the Bohol town near Calape that suffered the most damage with more than 40 dead.
On Thursday, authorities said that rescuers and emergency supplies were getting through to towns that had been isolated by the quake and where residents were camped out in tents waiting for assistance and to start repairing homes.
