Can Daily Drills of Ventilation Corrective Steps Improve Mask Ventilation of Preterm Infants in the Delivery Room? – A Randomized Controlled Trial
This randomized controlled trial demonstrates that brief, daily simulation drills of MR SOPA ventilation corrective steps significantly reduce mask leak during positive pressure ventilation in delivery room resuscitations of preterm infants compared to self-directed review of the NRP algorithm.

When a baby is born prematurely, the transition from the safety of the womb to the air of the delivery room is a fragile and critical moment. For many of these infants, the lungs are not ready to breathe on their own, and the most vital first step is to help them take that first breath. Healthcare providers do this by placing a soft mask over the baby's face and gently squeezing a bag to push air into the lungs. This process, known as positive-pressure ventilation, is the cornerstone of saving a newborn who cannot breathe. However, getting this technique right is surprisingly difficult. Even for experienced doctors and nurses, the mask often does not seal perfectly against the baby's tiny face, allowing air to escape. This leakage means the baby does not receive enough air to expand their lungs, which can delay recovery and lead to serious health problems. Because the air is invisible and the baby is small, it is hard for the person holding the mask to know in the moment if they are doing a good job or if the air is simply leaking out.
To address this challenge, a team of researchers at the University of Alberta in Canada set out to test a specific training method. They wanted to know if practicing a simple, structured checklist every single day would help medical staff perform better when a real baby needed help. The checklist they focused on is called MR SOPA, a set of six steps designed to fix common problems with mask ventilation. The steps involve adjusting the mask, repositioning the baby's head, clearing the mouth and nose, opening the mouth, increasing the pressure, or trying a different airway if the first one fails. While these steps are taught in standard training courses, the researchers wondered if repeating them briefly every day, like a daily drill, would make a measurable difference in the actual delivery room.
The study took place over a year and a half, involving seventy healthcare professionals who work with newborns, including doctors, nurses, and respiratory therapists. The team was split into two groups. One group spent five minutes at the start of every shift practicing the MR SOPA steps on a realistic baby simulator, receiving immediate feedback from an instructor. The other group spent the same five minutes reviewing the written instructions on their own, without the hands-on practice or the instructor. The researchers then watched what happened when these staff members cared for real premature babies born before thirty-three weeks of gestation. To see exactly what was happening without influencing the staff, they used a hidden device that measured how much air actually went into the baby's lungs and how much leaked out, alongside video recordings of the resuscitations.
The results showed a clear difference between the two groups. When the researchers analyzed thousands of breaths given to fifty premature infants, they found that the staff who practiced the daily drills had significantly less air leakage. In the group that practiced the steps on the simulator, the median amount of air that escaped around the mask was thirty-two percent. In the group that only read the instructions, the leakage was higher, at thirty-six percent. While a few percentage points might seem small, in the context of a tiny, fragile infant, this reduction represents a meaningful improvement in the quality of care. The staff who practiced daily were better at keeping the seal tight and delivering the air where it was needed.
Interestingly, the study did not find a difference in the final health outcomes of the babies, such as how long they stayed in the hospital or whether they developed specific lung diseases. The researchers noted that the study was designed to measure the skill of the staff, not the long-term health of the infants, and that a much larger study would be needed to see if better ventilation leads to better survival rates. However, the participants themselves felt the difference. Those who did the daily drills reported that the training improved their practical skills and made them feel more confident in their ability to help a baby in distress, compared to those who only read the material.
This research suggests that the way medical teams are trained matters. It shows that short, focused, and repeated practice of a specific skill can translate into better performance when a real emergency occurs. The findings support the idea that simulation training is most valuable not just when it happens in a classroom, but when it changes what a doctor or nurse does at the bedside. By turning a complex set of corrective steps into a daily habit, healthcare providers can reduce the amount of air lost during the critical first minutes of a premature baby's life, giving the infant a stronger start.
