Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q2 i? In some settings, feedback provided by trained instructors was found to be as effective as mechanical feedback systems for CPR quality. → Sabery Mahdieh 2026

q2 · i? · review · r2
The review reports, citing Pavo et al. (2016), that in a two-rescuer scenario with medical students, human feedback was equivalent to mechanical feedback in terms of the effective compression ratio, and the human feedback group initiated compressions more quickly.
"Feedback provided by trained instructors was, in some settings, found to be as effective as mechanical systems [23]."
