Abstract

Aim:

To examine user ability and preference in performing bag-mask ventilation (BMV) with four different configurations of infant mannequins.

Methods:

Participants provided a 30-second period of BMV to a Resusci Baby mannequin (RB), NeoNatalie mannequin (NN), NN filled with air (NNA), NN filled with water (NNW) and NN filled with 50% air and 50% water mix (NNAW). Participants rated the fidelity of each configuration.

Results:

Of the 20 participants, 65% rated NNW as having a high level of fidelity (HLF) ‘to hold’ (50% for NNAW, 10% for RB and 0% for NNA) (p < 0.001). Half rated NNAW as having a HLF in ‘tone’ (40% for NNW, 20% for RB and 5% for NNA) (p = 0.008). About 45% of participants rated NNAW as having a HLF in ‘appearance’ (45% for the RB, 20% for NNA and 15% for NNW) (p = 0.035). About 35% of participants rated NNAW as having a HLF in how it ‘felt to touch’ (30% for NNW, 15% for RB and 10% for NNA) (p = 0.008). Half of participants rated NNAW as having a HLF in terms of ‘weight’ (45% for NNW, 40% for RB and 0% for NNA) (p = 0.003). Participants delivered the greatest number of effective ventilations to the NNW mannequin.

Conclusion:

The NNW and NNAW configurations had the highest fidelity and had the highest percentage of effective ventilations delivered.
