design and experimental investigation of ultra low frequency vibration isolation during Neonatal Transport
Mechanical Systems and Signal Processing, 2020Co-Authors: Qiang Wang, Jiaxi Zhou, Huajiang OuyangAbstract:Abstract To resolve the tough issue of ultra-low frequency vibration isolation during Neonatal Transport, a new incubator with quasi-zero-stiffness (QZS) isolators is proposed. In the new incubator, the infant housing unit is supported by the QZS isolators to mitigate mechanical vibration being transmitted from the ambulance floor to the infant. Each of the QZS isolators is devised by combining a pair of permanent magnet rings and a coil spring, and the design parameters are realized by the equivalent magnetic charge method. Both the prototypes of the QZS isolator and incubator are manufactured, and their vibration isolation performances are tested. The results show that the QZS isolator can fulfil vibration isolation from 2 Hz, and the incubator with four such QZS isolators is effective from 3.2 Hz under the designated payload. Most importantly, the acceleration response of the infant model in the housing unit is much lower than the base excitation, when the incubator is driven by a random base excitation with frequency bandwidth from 2 Hz to 15 Hz.

Vibration isolation in Neonatal Transport by using a quasi-zero-stiffness isolator:
Journal of Vibration and Control, 2017Co-Authors: Jiaxi Zhou, Kai Wang, Huajiang OuyangAbstract:New-born infants are likely to suffer excessive vibration during Neonatal Transport, but there is no effective method to attenuate the transmission of vibration from the ambulance floor to an infan...

Rethinking the Neonatal Transport ground ambulance
Italian Journal of Pediatrics, 2019Co-Authors: Catherine Bellini, Martina Biasi, Roberto Aufieri, Diego Minghetti, Silvia Pericu, Martina Cavalieri, Niccolò Casiddu, Luca A Ramenghi, M. Gente, Sin) On Behalf Of The Neonatal Transport Study Group OfAbstract:ObjectivesThis article describes the detailed project aimed to realize a dedicated ground ambulance for Neonatal emergency Transport service (NETS). To date, the European Community rules specify requirements for the design, testing, performance, and equipping of road ambulance used for Transport and care of adult injured or ill patients, completely ignoring Neonatal Transport.MethodsThe project consisted of electric and gas supply planning, interior design taking into account ergonomic and occupant protection principles, both during travel and during medical care performances.ResultsA detailed project is presented. Main differences between European Type C ambulance and the new proposed Type D Neonatal ground ambulance are the presence on board of air compressed cylinder, iNO cylinders and delivery system, phototheraphy, shock adsorbing stretcher support, cooling device, patient’s placenta (refrigeration box), and transcutaneous gas analyzer.ConclusionThe European Community rules specify requirements for road ambulance used for Transport and care of adult injured or ill patients, completely ignoring Neonatal Transport.This study describes the detailed project aimed to realize a dedicated ground ambulance for Neonatal emergency Transport service. This study demonstrated that it is not possible simply to adapt the currently dedicated ambulance for mobile intensive care and resuscitation services (actual type C European Community) in a modern dedicated NETS ambulance; it is of paramount importance suggesting to European Community to introduce a further ambulance type, to be identified type D, strictly reserved to Neonatal Transport activities.

Neonatal Transport Services
Neonatology, 2012Co-Authors: Rocco Agostino, Roberto AufieriAbstract:Neonatal transfer is necessary when a newborn baby needs care that cannot be provided in the referral centre. Since it represents an additional risk factor for a critically ill neonate [1, 2], it should be performed, when possible, by a well-organized Neonatal Transport service.

Therapeutic hypothermia on Neonatal Transport: 4-year experience in a single NICU
Journal of Perinatology, 2010Co-Authors: K Fairchild, D Sokora, J Scott, S ZanelliAbstract:Objective: Therapeutic hypothermia instituted within 6 h of birth has been shown to improve neurodevelopmental outcomes in term newborns with moderate–to–severe hypoxic–ischemic encephalopathy (HIE). The majority of infants who would benefit from cooling are born at centers that do not offer the therapy, and adding the time for Transport will result in delays in therapy, that may lead to suboptimal or no neuroprotection for some patients. Our objective was to evaluate the effect of our center's experience with therapeutic hypothermia on Neonatal Transport. Study Design: Retrospective review of all cases of therapeutic hypothermia at a single Neonatal intensive care unit from 2005 to 2009. Result: Of 50 infants with HIE treated with hypothermia, 40 were outborn and 35 were cooled on Transport. The majority of patients were passively cooled by the referring clinicians, then actively cooled by our Transport team. Overcooling to
