Semin Fetal Neonatal Med 2021 Apr 19;26(2):101233. Epub 2021 Mar 19.

The Westmead Hospital Neonatal Intensive Care Unit, Australia; The University of Sydney, Department of Paediatrics and Child Health, Australia. Electronic address:

Infant resuscitation devices used at birth must be capable of delivering adequate and consistent ventilation in a controlled and predictable manner to a wide patient weight range, and combinations of transitional lung states. Manual inflation resuscitation devices delivering positive pressure lung inflation at birth can be classified broadly into two types: 1) flow generating, ie silicone self-inflating bags (SIB) also known as bag valve mask (BVM) and 2) flow dependent, ie anaesthetic flow inflating bag (FIB) and t-piece resuscitator (TPR) systems (eg: Neopuff, GE Panda and Draeger Resuscitaires). Globalization, lower production costs, and an expanding market need for devices, has led to a proliferation of brands (both reusable and single use) within a class type. Read More

Relationship Between Self-efficacy and Performance of Simulated Neonatal Chest Compressions and Ventilation.

Simul Healthc 2020 Dec;15(6):377-381

From the Department of Pediatrics (L.T.D., M.A.U., K.R.H.), University of California, Davis, Sacramento, CA.

Introduction: Because improved competence in caring for patients is difficult to measure, self-efficacy (the strength of one's belief in one's ability to complete a task) is often used as a surrogate measurement of clinical ability. However, studies in adults and children have shown at best only weak correlations between self-efficacy and performance. This correlation has not been well studied in neonatal resuscitation limiting the utility of self-efficacy as a measurement of the effectiveness of interventions in this population. Read More
