Summary
When critically ill premature infants require transfer by ambulance to another hospital, they frequently require mechanical ventilation. This observational study investigated acceleration during emergency transfers and looked at whether they result from changes in ambulance speed and direction, or from vibration due to road conditions. It aimed to assess how these forces impact on performance of neonatal ventilators and on patient-ventilator interactions.
The authors found that infants are exposed to significant acceleration and vibration during emergency transport. Although these forces do not interfere with overall maintenance of ventilator parameters, they make the pressure-volume loops more irregular.
