“…The importance of an early start with bystander cardiopulmonary resuscitation has previously been demonstrated in a more selected group of patients, those with a witnessed cardiac arrest and showing ventricular fibrillation on the first recorded ECG [7] . The markedly decreasing effect of bystander cardiopulmonary resuscitation on survival if there is a long delay from arrest to its start illustrates the previously described deleterious effects of prolonged ischaemia on the human body [12] . Our result underscores the importance of good lay cardiopulmonary resuscitation training, with the emphasis on the need to act rapidly.…”

The effect of bystander cardiopulmonary resuscitation on survival after an out-of-hospital cardiac arrest can be modified by various factors. Factors that were associated with the effect of bystander cardiopulmonary resuscitation were the interval between the collapse and the start of bystander cardiopulmonary resuscitation, the quality of bystander cardiopulmonary resuscitation, whether or not the bystander was a layperson, the interval between collapse and the arrival of the ambulance, age and the place of arrest.

“…In contrast, measurement of ventilation rate has been less well characterized, in part due to limitations of clinically available methods. While capnography has been extensively used during laboratory studies of CPR,9, 18, 19 and has been used as a predictor of resuscitation success during human cardiac arrest,20–22 the use of capnography to monitor ventilation rate during actual CPR has not been established. Given the important impact of ventilation rate on hemodynamics and clinical outcomes, careful measurement of ventilation rate to allow for real-time feedback remains an important goal to improve resuscitation care.…”

Capnography and chest-wall impedance algorithms for ventilation detection during cardiopulmonary resuscitation

et al. 2010

Objective-Hyperventilation is both common and detrimental during cardiopulmonary resuscitation (CPR). Chest wall impedance algorithms have been developed to detect ventilations during CPR. However, impedance signals are challenged by noise artifact from multiple sources, including chest compressions. Capnography has been proposed as an alternate method to measure ventilations. We sought to assess and compare the adequacy of these two approaches.Methods-Continuous chest wall impedance and capnography were recorded during consecutive in-hospital cardiac arrests. Algorithms utilizing each of these data sources were compared to a manually determined "gold standard" reference ventilation rate. In addition, a combination algorithm, which utilized the highest of the impedance or capnography values in any given minute, was similarly evaluated.Results-Data were collected from 37 cardiac arrests, yielding 438 min of data with continuous chest compressions and concurrent recording of impedance and capnography. The manually calculated mean ventilation rate was 13.3±4.3/min. In comparison, the defibrillator's impedancebased algorithm yielded an average rate of 11.3±4.4/min (p=0.0001) while the capnography rate was 11.7±3.7/min (p=0.0009). There was no significant difference in sensitivity and positive predictive value between the two methods. The combination algorithm rate was 12.4±3.5/min (p=0.02), which yielded the highest fraction of minutes with respiratory rates within 2/min of the reference.

The manuscript will undergo copyediting, typesetting, and review of the resulting proof before it is published in its final citable form. Please note that during the production process errors may be discovered which could affect the content, and all legal disclaimers that apply to the journal pertain. Conclusions-Both the impedance and capnography-based algorithms underestimated the ventilation rate. Reliable ventilation rate determination may require a novel combination of multiple algorithms during resuscitation. Conflict of Interest

“…This study also shows that the hemodynamic and survival benefits of the use of ETCO 2directed chest compression delivery is limited by asphyxia durations of 23 minutes. The duration of arrest is an established, independent determinant of obtaining ROSC (36)(37)(38). We chose longer periods of asphyxia than the commonly used 10-12 minutes because of the potential for physiologic feedback to improve outcomes when CPR is prolonged.…”
