limitations: the summary of the studies in this review has a number of limitations. first, most of the included studies were small and often preliminary and had serious limitations. second, quality of some evidence was low in some areas and is likely biased in favor of mechanical cpr devices. for example, although they were adequately powered, some studies did not report the actual number of patients enrolled or reported only medians. third, the studies included different patient populations, depending on the study design and the relative ease of implementing cpr versus mechanical cpr. fourth, different outcome measures (eg, survival to hospital discharge, survival to hospital discharge with good neurological outcome) were evaluated. fifth, different types of mechanical cpr devices were used, depending on the study. sixth, some of the included studies showed high heterogeneity in the use of cpr techniques, as well as in the timing of cpr and defibrillation. some studies did not report actual hands-off time; in others, durations were used, which may be misleading if cpr and defibrillation is used intermittently rather than continuously. therefore, more high-quality studies are needed to adequately evaluate and compare mechanical cpr devices with manual cpr. first, all-cause mortality studies should be used, as in circ and paramedic trials, as this captures deaths caused by cardiac arrest, and those related to the resuscitation attempts. these studies, in addition to evaluating survival to hospital discharge, should also aim to evaluate outcomes at discharge, including quality of life and functional status. in addition, long-term survival and return-to-work outcomes should be evaluated. second, cohort studies with rigorous assessments of cpr techniques, hands-off time, and defibrillation should be conducted. third, early studies should collect and analyze outcomes in a prospective manner, with a randomized, controlled, and blinded design with comparable mechanical cpr and manual cpr groups. fourth, data from large, multicenter, randomized controlled trials are needed to evaluate the frequency and duration of cpr and defibrillation, as well as optimal use of cpr and defibrillation devices. fifth, studies of mechanical cpr should consider the impact of avoidance of ineffective (nonphysiologic) cpr on outcomes. finally, studies should consider economic issues, including the impact of resource utilization and cost-effectiveness (ie, cost per survivor).

recommendation-specific supportive text healthcare providers should consider the possibility of a spinal injury before opening the airway. if a spinal injury is suspected or cannot be ruled out, providers should open the airway by using a jaw thrust instead of head tiltchin lift. 2 maintaining a patent airway and providing adequate ventilation and oxygenation are priorities during cpr. if a jaw thrust and/or insertion of an airway adjunct are ineffective in opening the airway and allowing ventilation to occur, a head tiltchin lift may be the only way to open the airway. in these cases, this maneuver should be used even in cases of potential spinal injury because the need to open the airway outweighs the risk of further spinal damage in the cardiac arrest patient. when spinal injury is suspected or cannot be ruled out, rescuers should maintain manual spinal motion restriction and not use immobilization devices. manual stabilization can decrease movement of the cervical spine during patient care while allowing for proper ventilation and airway control. 23, 24 spinal immobilization devices may make it more difficult to maintain airway patency 25, 26 and provide adequate ventilation. this topic last received formal evidence review in 2010. 22
recommendation-specific supportive text interposed abdominal compression cpr is a 3-rescuer technique that includes conventional chest compressions combined with alternating abdominal compressions. the dedicated rescuer who provides manual abdominal compressions will compress the abdomen midway between the xiphoid and the umbilicus during the relaxation phase of chest compression.
