Objective: to provide and explore possibility of new idea that perform mouth-to-mouth ventilation through cardiopulmonary resuscitation. Methods: stage one was establishing the ventilation technique using cola bottles, stage two was measuring the tidal volume when different sized cola bottles were used. Result: the smallest sized cola bottle (500 ml) could also make obvious thorax rise in manikin CPR model. The tidal volume was 174.5 ± 9.1 ml, 220 ± 7.6 ml and 447 ± 15.9 ml respectively for 500 ml, 600 ml and 1.25 L cola bottles when using single hand performance. There were statistical differences (0.001) in tidal volume of different sized cola bottle by using one hand performance and two hands. Conclusion: Larger sized cola bottles (600 ml, 1.25 L) could be used as substitute ventilation technique for mouth-to-mouth ventilation in special circumnutates.

When cardiac arrest occurs, cardiopulmonary resuscitation (CPR) should be started with chest compressions first. The use of ventilations is determined by the training of rescuers, their ability and willingness to provide rescue breaths, patient characteristics, and the underlying cause of the cardiac arrest. Trained rescuers should give two ventilations after every 30 compressions, or once the airway is secured with a tracheal tube, ventilate the patient at 10 breaths/min without any pause in chest compressions. Rescuers who are unable or unwilling to provide effective ventilation, while awaiting expert help should use compression-only CPR. Ventilations are needed for the treatment of cardiac arrest in children, when arrest is from a primary respiratory cause, or during a prolonged cardiac arrest. Choice of ventilation technique depends on rescuer skills and the airway used. Effective oxygenation and ventilation can be maintained during CPR with a tidal volume of approximately 500 mL given over an inspiratory time of 1 second. Rescuers should give supplemental oxygen in as high a concentration as possible during CPR in order to rapidly correct tissue hypoxia. Once restoration of a spontaneous circulation has been achieved the inspired oxygen should be adjusted to maintain oxygen saturation between 94 and 98%.

BACKGROUND Cardiopulmonary resuscitation (CPR) is rarely performed by dental staff. The availability of automated external defibrillators (AED) is increasing. Personal tutor training with a manikin is the most common way to teach CPR. But internet-learning approaches, such as video-based teaching, are gaining popularity. OBJECTIVE This pilot study has been designed to compare the performance of CPR after two teaching methods in a simulated cardiac arrest situation. A personal tutor demonstration was compared with a web-based video demonstration. The main hypothesis was that more than 70% of the participants of the tutor-instructed group would start CPR within 10 seconds (s), while only up to 30% of the participants of the web-based video-instructed group would start within this time. METHODS One group of dental students received a 5.5 minutes (min) AED-CPR demonstration by a tutor on a manikin (T-/control group n=23 teams of two). A second group watched a 7min web-based AED-CPR instruction video (W-/intervention group n=23 teams of two). No repetition was offered, no questions or practice allowed. CPR performance was video-recorded and analyzed by two examiners. RESULTS No differences concerning the onset and quality of CPR were found. Students started CPR after detection of cardiac arrest with a minimum delay (median=6s (T)/6s (W); IQR=5/7; P=.52). Tidal volume and chest compression depths were insufficient in both groups (tidal volume: median=14 milliliters (ml) (T)/58ml (W); IQR=218.5/148.5; P=.9; depths: median=30 millimeters (mm) (T)/20mm (W); IQR=12.5/10; P=.02). Tutor-instructed teams compressed deeper, but both groups did not meet the recommended standard. Chest compression rate was in the recommended interval (median=113 (T)/111 compressions/minute (W); IQR=24.5/20; P=.46). More students of the web-based video-instructed group had problems using the AED (T=7 teams; W=14; P=.04) but all except one team continued CPR. They did not focus on the problems with the AED and were able to trigger a shock (T=21 teams; W=19; P=.38). Restart of CPR after the shock within 10s was achieved at almost equal time intervals (median=5s (T)/6s (W); IQR=3/4; P=.54). CONCLUSIONS Dental students can acquire basic knowledge in AED-assisted CPR in similar quality by a short web-based video simulation compared with a short demonstration by a tutor. Contrary to expectations, most parameters of CPR and AED performance quality of web-based video-instructed group were not different to students of the tutor-instructed group. The recommended tidal volume had not been achieved in both groups. Chest compression depth seems to be a parameter that has been more difficult to teach to the web-based video-instructed group. No delays of standard CPR measures were observed after detection of cardiac arrest in both groups. The use of the AED did not distract the attention of the rescuers from the simulated patient.

ABSTRACTBackgroundDespite efforts to initially contain Severe Acute Respiratory Syndrome Coronavirus (SARS-CoV-2), it has spread worldwide and has strained international healthcare systems to the point where advanced respiratory resources and ventilators are depleted. This study aims to explore splitting ventilators, or “multi-ventilation,” as a viable alternative in these demanding times. We investigated whether individualized tidal volume and positive end expiratory pressure (PEEP) delivery is possible to lungs of different compliances that are being simultaneously ventilated from one anesthesia ventilator.MethodsWe performed a controlled experiment in an operating room environment without animal or human participants. Two “test lungs” were connected to distinct modified Y-pieces that were ventilated in parallel from a single anesthesia ventilator.ResultsVentilation can be manipulated to qualitatively deliver individually tailored tidal volumes in the setting of varying PEEP and compliance requirements in pressure control mode.ConclusionsSplitting ventilators, or “multi-ventilation,” is a viable alternative to acute ventilator shortage during a pandemic. Ventilators can be split for individualized tidal volume and positive end-expiratory pressure delivery in multiple subjects of differing compliances and demographics.

Given the importance of increased coronary and cerebral perfusion pressure during cardiopulmonary resuscitation, the recommendation of limiting tidal volume and ventilation rate to 10 per minute in order not to inhibit venous return seems to be correct. However, although the resuscitation community believes that positive-pressure ventilation during cardiopulmonary resuscitation is bad for the circulation, proper timing of compression and ventilation may actually improve the circulation.
