Background: Respiratory function monitors (RFMs) have been used extensively in manikin and infant studies yet have not become the standard of training. We report the outcomes of a new portable, lightweight RFM, the Juno, designed to show mask leak and deflation tidal volume to assist in positive pressure ventilation (PPV) competency training using manikins.
Methods: Two leak-free manikins (preterm and term) were used. Participants provided PPV to manikins using two randomised devices, self-inflating bag (SIB) and T-piece resuscitator (TPR), with Juno display initially blinded then unblinded in four 90 s paired sequences, aiming for adequate chest wall rise and target minimal mask leak with appropriate target delivered volume when using the monitor.
Results: 49 experienced neonatal staff delivered 15 569 inflations to the term manikin and 14 580 inflations to the preterm. Comparing blinded to unblinded RFM display, there were significant reductions in all groups in the number of inflations out of target range volumes (preterm: SIB 22.6-6.6%, TPR 7.1-4.2% and term: SIB 54.8-37.8%, TPR 67.2-63.8%). The percentage of mask leak inflations >60% was reduced in preterm: SIB 20.7-7.2%, TPR 23.4-7.4% and in term: SIB 8.7-3.6%, TPR 23.5-6.2%).
Conclusions: Using the Juno monitor during simulated resuscitation significantly improved mask leak and delivered ventilation among otherwise experienced staff using preterm and term manikins. The Juno is a novel RFM that may assist in teaching and self-assessment of resuscitation PPV technique.

Background: This study aimed to evaluate the efficacy of Chest-Compression-Synchronized-Ventilation (CCSV) using supraglottic airway devices (SGA) compared to tracheal intubation (TI) for ventilation during continuous resuscitation.
Methods: In this cross-over study, the lungs of adult Thiel-embalmed cadavers were initially recruited using TI. Subsequently, various SGA (Laryngeal-Mask=Ambu®AuraGain™, Laryngeal-Tube=LTS-D®, i-gel-Laryngeal-Mask=I-GEL®) and TI were applied in randomized order during continuous chest compressions.

Gas leak detection in oil and gas processing facilities is a critical component of the safety production monitoring system. Non-contact detection technology based on infrared imaging has emerged as a vital real-time monitoring method due to its rapid response and extensive coverage. However, existing pixel-level segmentation networks face challenges such as insufficient segmentation accuracy, rough gas edges, and jagged boundaries.

This study aimed to evaluate the efficacy and reliability of maintaining a constant tidal volume (V) using a square-wave flow pattern in currently available turbine-based ventilators (TBVs) compared with a bellows-based ventilator (BBV), under conditions of abrupt changes in ventilator load. Such changes frequently occur in ventilator-dependent patients during mouthpiece ventilation and sleep with a mask, including events such as air stacking (AS), leakage, disconnection for speaking or eating/drinking, and complete obstruction. Five TBVs and one BBV were assessed in a bench test simulating 4 distinct transient events (AS, leakage, disconnection, and complete obstruction) across 3 consecutive cycles.

Background: Positive pressure ventilation with partially (25 ml) vs. fully (35 ml) inflated face mask was compared in terms of applied forces on a newborn manikin face, cuff pressure and air leak.
Methods: A crossover randomized controlled trial of face mask ventilation with partially (25 ml) vs.

Respiratory function monitors (RFMs) can provide real-time data including expiratory tidal volumes and interface leak during delivery room (DR) neonatal resuscitation. However, concerns have been raised within previous randomised controlled trials and systematic reviews that effectuating RFMs routinely for DR resuscitation is limited by lack of comprehensive staff training. The International Liaison Committee on Resuscitation have also recently declared a knowledge gap in terms of the training required to be competent in utilising an RFM during neonatal resuscitation.
