130 Abstracts / Resuscitation 96S (2015) 43–157 Materials and methods: Structures of hearts were observed by echocardiography during full expiration and inspiration phases of breathing. Investigator requested children for forceful breath- ing and asked to hold 5 seconds to observe parasternal long axis and short axis view. If children could not follow the investiga- tor’s request, investigator tried to observe changes of heart position during normal breathing. Results: Forty children were enrolled. 24 (60%) were male and mean age was 6 (±2.4) years. At full expiration phases, 80% (32/40) of left ventricles were placed underneathinter-mammalian line. 10% (4/40) of left ventricles were found underneath just upper of inter-mammalian line and remains were found just below. Their left lobes of livers were placed under lower half level of sternum in all cases. Conclusions: This study has identified that, in children, left ven- tricle might be placed beneath upper or middle of inter-mammalian line, not below inter-mammalian line. The proper location of chest compression might be a middle of inter-mammalian line for better cardiac output with avoidance of hepatic damage.

Methods: An on-line survey was carried out after worldwide distribution to professionals involved in the treatment of paediatric cardiac arrest. Results: 477 professionals from 46 countries answered. 97.7% refer adherence to CPR guidelines (47.7% AHA, 31.8% ERC, 17.8% local and 3.4% unit specific guidelines). 74.9% refer that they never perform chest compressions with- out ventilation. This is referred by 82.9% of those following ERC guidelines and 66.5% of those following AHA guidelines (p = 0.003). Respiratory rate is usually (31.4%) adjusted to patient char- acteristics. In children over 1 year, most frequent respiratory rate is 13–20 rpm for intubated (46%) and non-intubated (41.8%) patients. Under 1 year of age, most frequent rates are 21–30 rpm for intubated patients (37.3%) and both 13–20 rpm and 21–30 rpm in non-intubated (26.5% each). In non-intubated patients, a res- piratory rate between 7 and 12 rpm is used by only 27.6% of professionals in children under 1 year of age and by 41% of pro- fessionals in children over 1 year. In intubated patients, respiratory rate between 10 and 12 rpm is used by 16.7% of professionals in children under 1 year and by 27.3% in older children. A respiratory rate of 7–12 rpm is more frequently used in North America than in Europe, Central America and South America (p < 0.001). Self-inflating ventilation bag was used more frequently by pro- fessionals following ERC guidelines (98.6%) than on those following AHA guidelines (93.2%) (p = 0.015). 87.2% coordinates chest compressions with ventilation in non-intubated patients. Compressions were more frequently coor- dinated with ventilation by professionals following ERC guidelines (91.1%) than when following AHA guidelines (81.5%) (p = 0.011). Conclusions: Ventilation practices during CPR in children are variable worldwide. Many practitioners do not follow the interna- tional recommendations about respiratory rate during CPR. http://dx.doi.org/10.1016/j.resuscitation.2015.09.309 AP213 Religion and life support withdrawal in children: What do Healthcare Providers wish? Karen Torres 1,* , Sharon Einav 2 , Rafael Villarreal 1 , Joseph Varon 1 1 University General Hospital, Houston, TX, USA 2 Shaare Tzedek Medical Center, Jerusalem, Israel Purpose of the study: To study the relationship of faith with hypothetical life-support withdrawal decisions for their own chil- dren among healthcare providers. Materials and methods: We surveyed the healthcare providers and ancillary staff of 9 healthcare institutions in the United States, Mexico and Panama. A 33-question “End-of-Life-Questionnaire” survey was completed by 858 workers. The main outcome mea- sure was willingness to withdraw medical care even if this contradicted a religious edict. Statistics were mainly descriptive. Chi-square/Fisher’s exact p < 0.05, were used to indicate a significant association. Results: The study included 180 physicians (21%), 317 nurses (36.9%), and 354 other healthcare institution workers (41.2%). Most (41.5%, n = 356) were married and 57% (n = 489) had children. The large majority of responders (51.9%, n = 445) denoted them- selves as Catholic. On a scale of 1–5 (1 being not spiritual and 5 being very spiritual), 39.6% defined themselves as very spiri- tual, 51% somewhat spiritual and 6.5% did not view themselves as being spiritual. Association was found between having chil- dren and willingness to withdraw care, even if this contradicted a religious edict (p = 0.036). Those who stated they had children 23% (114/483), would withdraw care; and among the respondents without children, 17.6% (63/357), would withdraw care (p = 0.040). This association was particularly strong in non-doctor, non-nurse, staff members [among those with children 26.6% (50/188) would withdraw care vs. among those without children 15.5% (26/168), p= 0.013]. Contrastingly, among medical-professionals (i.e. doctors
