Abstract:
Purpose : Healthcare providers are often unable to perform chest compressions (CC) consistently within AHA guideline recommendations of 100 CC/minute at a depth of 1.5–2 in. The present study examined the effect of audiovisual CPR feedback on the quality of CC performed by healthcare providers. Methods: One hundred twenty-five ACLS and BCLS trained hospital based healthcare professionals participated in “CPR challenges” at 14 U.S. hospitals. Participants performed 2 minutes of CC on a manikin without any feedback initially. Following a ≥90 second rest period and ~20 second orientation to the audiovisual feedback prompts, participants repeated 2 minutes of CC with feedback prompts. Data were recorded using a ZOLL AED Plus. Rescuers were categorized based upon mean depth of CC without feedback: 1) under-performers (depth 〈 1.5in; n=60); 2) within guideline-performers (depth 〈 1.5–2in; n=52); and 3) over-performers (depth 〉 2in; n=13). Results: Mean depth of CC improved with CPR feedback (1.57±0.36in without feedback vs. 1.71±0.13in with feedback, mean±SD, p 〈 0.0001) and the percentage of CC within 1.5–2in increased from 38 to 87% (p 〈 0.0001). In under-performers, depth of CC substantially increased with CPR feedback (1.30±0.12 vs. 1.66±0.13in; p 〈 0.0001) and the percentage of CC within 1.5–2in improved from 9 to 81% (p 〈 0.0001). Over-performers were corrected to meet AHA guidelines for depth with feedback (2.31±0.40 vs. 1.83±0.07in, p=0.001). The percentage of CC within 1.5–2 in improved from 13 to 90% with feedback (p 〈 0.0001). For within guideline-performers, depth of CC was similar with and without feedback (1.70±0.14 vs.1.74±0.10in, p=0.08) but the percentage of CC within 1.5–2 in increased with feedback from 79 to 92% (p 〈 0.0001). Rate of CC was corrected with CPR feedback in under-performers (110±17 vs. 100±4 CC/min, p 〈 0.0001) but was unchanged with feedback in within guideline-performers (103±15 vs. 100±3 CC/min, p=0.2) and over-performers (97±14 vs. 100±8 CC/min, p=0.4). Conclusions: Audiovisual feedback improves the quality of CC provided by hospital-based healthcare professionals in a manikin testing scenario. Healthcare providers can improve consistency of CC with CPR feedback regardless of their performance without feedback.
