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
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.
"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
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
After six weeks of classroom and simulation experience, the nurses will train with human patients.
In recent years,
"It's a very efficient way to learn. You'd have to listen to 100 different patients to get all the skills that students can learn from a simulator," said
She said the devices have become more popular as prices have come down. The first simulator cost about
"The use of simulation is growing tremendously, and has become the standard at teaching institutions," Mitchell said.
NSU bought three high-tech simulators named Stan, which are being used by first- and second-year medical students in the classroom and by the school's surgery club. Stan's eyes can dilate. His thumb can twitch. His lungs expand and contract.
Students can listen for the same sounds they would hear in a human patient, and they don't have to feel bad if they don't get it the first time, said Assistant
Students "spend so much time studying," she said. "It's exciting when they can do things that make them feel like a doctor. The more students feel motivated to practice, the more we're going to improve the quality of patient care."
