Ventilation feedback device for Manual Ventilation in simulated respiratory arrest a crossover manikin study
Scandinavian Journal of Trauma Resuscitation and Emergency Medicine, 2019Co-Authors: Abdo Khoury, Alban De Luca, F S Sall, Lionel Pazart, Gilles CapellierAbstract:Studies have shown that providing adequate Ventilation during CPR is essential. While hypoVentilation is often feared by most caregivers on the scene, the most critical problem remains hyperVentilation. We developed a Ventilation Feedback Device (VFD) for Manual Ventilation which monitors ventilatory parameters and provides direct feedback about Ventilation quality to the rescuer. This study aims to compare the quality of conventional Manual Ventilation to Ventilation with VFD on a simulated respiratory arrest patient. Forty healthcare providers were enrolled and instructed to ventilate a manikin simulating respiratory arrest. Participants were instructed to ventilate the manikin for 5 min with and without the VFD in random order. They were divided in two groups of 20 people, one group ventilating through a mask and the other through an endotracheal tube. Ventilation with the VFD improved from 15 to 90% (p < 0.001) with the mask and from 15 to 85% (p < 0.001) with the endotracheal tube (ETT) by significantly reducing the proportion of hyperVentilation. The mean Ventilation rates and tidal volumes were in the recommended ranges in respectively 100% with the mask and 97.5% of participants with the ETT when using the VFD. VFD improves the performance of Manual Ventilation by over 70% in different simulated scenarios. By providing the rescuer direct feedback and analysis of ventilatory parameters, this device can significantly improve Ventilation while performing CPR and thus save lives.

Manual Ventilation is a vital procedure, which remains difficult to achieve for patients who require ventilatory support.

We will give in this paper, a historical view on Manual Ventilation’s evolution throughout the last decades and describe the technical characteristics, advantages, and hazards of the main devices currently found in the market. Artificial Ventilation has developed progressively and research is still going on to improve the actual devices used. Throughout the past years, a brand-new generation of ventilators was developed, but little was done for Manual Ventilation. Many adverse outcomes due to faulty valve or misassembly were reported in the literature, as well as some difficulties to ensure efficient insufflation according to usual respiratory parameters.These serious incidents underline the importance of BVM system routine check and especially the unidirectional valve reassembly after sterilization, by only experienced and trained personnel.

A Self-Inflating Bag May Cause Hypocapnia in a Rabbit Model of Manual Ventilation Compared to the T-piece Resuscitator.
American Journal of Perinatology, 2017Co-Authors: Luciana Bertocco De Paiva Haddad, Renata Suman Mascaretti, Luciana A. P. A. Valle, Celso Moura RebelloAbstract:Background Manual Ventilation is a key aspect that determines the efficiency of neonatal resuscitation and may be performed by specialists using different equipment and professionals. Objective To compare Manual Ventilation using T-piece resuscitator and self-inflating bag in an experimental model, with regard to gasometric and respiratory mechanical parameters. Methods Adult rabbits were submitted to 10 minutes of Ventilation with each device operated by three groups of volunteers: physicians, physiotherapists, and nurses. We measured respiratory mechanics throughout the study as well as blood gas before and after Ventilation, and we compared professionals' performance on each device. Results Compared with T-piece, animals ventilated with the self-inflating bag in the nurse group (n = 7) presented a greater minute volume (390 ± 108 vs. 766 ± 410 mL/min, p Conclusion Self-inflating bag resulted in hypocapnia and respiratory alkalosis in the nurse group, and Ventilation using a T-piece resulted in a lower tidal and minute volume.

Manual Ventilation and Sustained Lung Inflation in an Experimental Model: Influence of Equipment Type and Operator’s Training
PLOS ONE, 2016Co-Authors: Cristiane Do Prado, Luciana Branco Haddad, Luciana Assis Pires Andrade Vale, Renata Suman Mascaretti, Ruth Guinsburg, Maria Fernanda Branco De Almeida, Celso Moura RebelloAbstract:Aim To compare the influence of devices for Manual Ventilation and individual experience on the applied respiratory mechanics and sustained lung inflation. Methods A total of 114 instructors and non-instructors from the Neonatal Resuscitation Program of the Brazilian Society of Pediatrics participated in this study. Participants ventilated an intubated manikin. To evaluate respiratory mechanics and sustained lung inflation parameters, a direct comparison was made between the self-inflating bag and the T-shaped resuscitator (T-piece), followed by an analysis of the effectiveness of the equipment according to the participants’ education and training. Results A difference between equipment types was observed for the tidal volume, with a median (interquartile range) of 28.5 mL (12.6) for the self-inflating bag and 20.1 mL (8.4) for the T-piece in the instructor group and 31.6 mL (14) for the self-inflating bag and 22.3 mL (8.8) for the T-piece in the non-instructor group. Higher inspiratory time values were observed with the T-piece in both groups of professionals, with no significant difference between them. The operator’s ability to maintain the target pressure over the 10 seconds of sustained lung inflation was evaluated using the area under the pressure-time curve and was 1.7-fold higher with the use of the T-piece. Inspiratory pressure and mean airway pressure applied during sustained lung inflation were greater with the self-inflating bag, as evaluated between the beginning and the end of the procedure. Conclusion The T-piece resulted in lower tidal volume and higher inspiratory time values, irrespective of the operator’s experience, and increased the ease of performing the sustained lung inflation maneuver, as demonstrated by the maintenance of target pressure for the desired period and a higher mean airway pressure than that obtained using the self-inflating bag.

RepRapable automated open source bag valve mask-based ventilator
Digital Commons @ Michigan Tech, 2020Co-Authors: Petsiuk Aliaksei, Tanikella, Nagendra Gautam, Dertinger, Samantha C., Pringle Adam, Oberloier Shane, Pearce, Joshua M.Abstract:This study describes the development of an automated bag valve mask (BVM) compression system, which, during acute shortages and supply chain disruptions can serve as a temporary emergency ventilator. The resuscitation system is based on the Arduino controller with a real-time operating system installed on a largely RepRap 3-D printable parametric component-based structure. The cost of the system is under $170, which makes it affordable for replication by makers around the world. The device provides a controlled breathing mode with tidal volumes from 100 to 800 milliliters, breathing rates from 5 to 40 breaths/minute, and inspiratory-to-expiratory ratio from 1:1 to 1:4. The system is designed for reliability and scalability of measurement circuits through the use of the serial peripheral interface and has the ability to connect additional hardware due to the object-oriented algorithmic approach. Experimental results demonstrate repeatability and accuracy exceeding human capabilities in BVM-based Manual Ventilation. Future work is necessary to further develop and test the system to make it acceptable for deployment outside of emergencies in clinical environments, however, the nature of the design is such that desired features are relatively easy to add with the test using protocols and parametric design files provided

Factors Affecting Manual Resuscitator Use: A Systematic Review [palavras-chave: Ventilador; Ressuscitação Cardiopulmonar; Ventilação Pulmonary]
2015Co-Authors: De Oliveira P.m.n., Almeida-junior A.a., Almeida C.c.b., De Ribeiro M.g.o., Ribeiro J.d.Abstract:Objective: The Manual resuscitator (RM) is a device that provides positive pressure Ventilation. Surveys conducted to assess the adequacy of Manual resuscitators to American Society for Testing and Materials standards show that several factors affect Manual Ventilation. However, results are conflicting. The aim of this study was to verify evidence of factors that influence pediatric/adult pulmonary Ventilation with Manual resuscitator by a systematic review. Data source: Original articles indexed in Medline, Lilacs and SciELO published from January 1986 to March 2011. The key-words used were: "Manual resuscitator", "Manual Ventilation", "positive pressure Ventilation" in Portuguese and English, as well as "bag-valve". Data Synthesis: 45 articles were selected, most of them experimental. The studies compared Manual resuscitator brands and models, and analyzed the physical characteristics of professionals. The effectiveness of Ventilation with Manual resuscitator depends on the brand, model and functional characteristics of the equipment. Ventilation also varies with the education, training and experience of the professional who handles the equipment. Other factors that can influence effectiveness are the Manual resuscitator compression form, the use of a pressure relief valve and the flow of oxygen provided to the Manual resuscitator. Conclusions: The variability of ventilatory parameters during Manual resuscitation does not allow a standardization of the technique, being harmful to cardiopulmonary resuscitation. Although most Manual resuscitator seem to follow international standards, the equipment must be evaluated in the clinical settings. There are few studies about pediatric and neonatal Manual resuscitator models

neonatal resuscitation 3 manometer use in a model of face mask Ventilation
Archives of Disease in Childhood-fetal and Neonatal Edition, 2005Co-Authors: Colm P F Odonnell, Peter G Davis, Peter A Dargaville, Lex W. Doyle, Colin J MorleyAbstract:Background: Adequate Ventilation is the key to successful neonatal resuscitation. Positive pressure Ventilation (PPV) is initiated with Manual Ventilation devices via face masks. These devices may be used with a manometer to measure airway pressures delivered. The expiratory tidal volume measured at the mask (V TE(mask) ) is a good estimate of the tidal volume delivered during simulated neonatal resuscitation. Aim: To assess the effect of viewing a manometer on the peak inspiratory pressures used, the volume delivered, and leakage from the face mask during PPV with two Manual Ventilation devices in a model of neonatal resuscitation. Methods: Participants gave PPV to a modified resuscitation mannequin using a Laerdal infant resuscitator and a Neopuff infant resuscitator at specified pressures ensuring adequate chest wall excursion. Each participant gave PPV to the mannequin with each device twice, viewing the manometer on one occasion and unable to see the manometer on the other. Data from participants were averaged for each device used with the manometer and without the manometer separately. Results: A total of 7767 inflations delivered by the 18 participants were recorded and analysed. Peak inspiratory pressures delivered were lower with the Laerdal device. There were no differences in leakage from the face mask or volumes delivered. Whether or not the manometer was visible made no difference to any measured variable. Conclusions: Viewing a manometer during PPV in this model of neonatal resuscitation does not affect the airway pressure or tidal volumes delivered or the degree of leakage from the face mask.

neonatal resuscitation 1 a model to measure inspired and expired tidal volumes and assess leakage at the face mask
Archives of Disease in Childhood-fetal and Neonatal Edition, 2005Co-Authors: Colm P F Odonnell, Peter G Davis, C O F Kamlin, Colin J MorleyAbstract:BACKGROUND: Neonatal resuscitation is a common and important intervention, and adequate Ventilation is the key to success. In the delivery room, positive pressure Ventilation is given with Manual Ventilation devices using face masks. Mannequins are widely used to teach and practise this technique. During both simulated and real neonatal resuscitation, chest excursion is used to assess tidal volume delivery, and leakage from the mask is not measured. OBJECTIVE: To describe a system that allows measurement of mask leakage and estimation of tidal volume delivery. METHODS: Respiratory function monitors, a modified resuscitation mannequin, and a computer were used to measure leakage from the mask and to assess tidal volume delivery in a model of neonatal resuscitation. RESULTS: The volume of gas passing through a flow sensor was measured at the face mask. This was a good estimate of the tidal volume entering and leaving the lung in this model. Gas leakage between the mask and mannequin was also measured. This occurred principally during inflation, although gas leakage during deflation was seen when the total leakage was large. A volume of gas that distended the mask but did not enter the lung was also measured. CONCLUSION: This system can be used to assess the effectiveness of positive pressure Ventilation given using a face mask during simulated neonatal resuscitation. It could be useful for teaching neonatal resuscitation and assessing Ventilation through a face mask.
