Medical simulators can breathe, bleed, give birth and help students hone skills

WEST PALM BEACH, Fla. — It was a high-stress situation for three nurses who had never delivered babies: A woman was 32 weeks pregnant, in pain and having contractions.

The doctor was running late, stuck in traffic. The nurses calmly checked the woman's vital signs, told her to push and even gave her moral support. "You're doing great, Mom," nurse Jascinth Brown, of Plantation General Hospital, told the patient. Fifteen minutes later, a premature but healthy baby girl came out feet first, a breech delivery.

Although the scenario felt real, the patient was a lifelike mannequin named Noele. Inside her was a baby mannequin, equipped with an umbilical cord and all.

Medical simulators have come a long way since the 1960s, when a lifeless dummy named Annie was first used to help teach CPR. Using computerized sensors to imitate real-life organs and human reactions, they can respond to real anesthesia gases, and mimic heart attacks and irregular heartbeats. They can breathe, bleed, cry, pass urine, speak some words and give birth.

And their use has been growing fast in South Florida, with dozens of hospitals, universities, community colleges, high schools and fire-rescue departments using the devices.

"It's close to lifelike," said Brown, who watched as her patient's vital signs were displayed on monitors during a recent training drill run by Florida Atlantic University. "I've worked in labs in nursing school, but I've never actually seen a delivery. Here we're simulating a baby actually coming out."

Experts say the simulators improve medical care by giving students a chance to learn crucial skills and make mistakes in a realistic setting, without any actual patients' lives hanging in the balance. Students are assessed, and sometimes even videotaped, during the drills. Instructors then discuss ways the students can improve their skills.

The nurses from Plantation hospital said they didn't take blood from the pregnant patient, a mistake they won't repeat.

"They gain the experience and confidence they need before being placed in a situation where their actions could mean the difference between the life and death of a patient," said Mark Goldstein, director of FAU's simulation center.

After six weeks of classroom and simulation experience, the nurses will train with human patients.
