Aim To compare the effectiveness of an in‐line EtCO 2 detector ( DET ) and a quantitative EtCO 2 detector ( CAP ), both attached to a t‐piece resuscitator, during PPV via a face mask. Methods Paediatric trainees were randomly assigned to determine the method of PPV they commenced with (No device ( ND ), DET or CAP ). Participants used each method for 2 min. Participants were video‐recorded to determine the amount of effective ventilations delivered with each method. Results Twenty‐three paediatric trainees provided a total of 6035 ventilations, and 91.2% were deemed effective. The percentages of median effective ventilations with the ND , the DET and the CAP were 91.0%, 93.0% and 94.0%, respectively. Fourteen (61%) of the trainees indicated a preference for the DET method, 8 (35%) for the CAP method, and 1 (4%) of the trainees indicated a preference for the ND method. Capnography was the most effective method per patient. Conclusion There was no adverse effect with the addition of EtCO 2 detectors. Trainees favoured methods of EtCO 2 monitoring during ventilation. The NeoStat device was the preferred device by the majority. The greatest efficacy was achieved with the capnography device. Capnography may enhance face mask ventilation.
