We also agree that the rate of technical failure is probably higher with level 3 HST because of the absence of an attending technician; however, we disagree with Dr. Goldstein's assertion that the technical specifications, and hence data quality, from level 3 HST devices are inferior to those of level 1 PSG. The fidelity of modern level 3 devices has advanced substantially, enabling data to be recorded at similar specifications as laboratory PSG. ...References1.
