“…The results are consistent with prior literature on the benefits of stepped enhancements to pulse oximetry sounds (Collett et al, 2020; Deschamps et al, 2016; Hinckfuss et al, 2022; Hinckfuss et al, 2016; Zestic et al, 2019). In previous studies, tremolo was mapped to SpO 2 non-target ranges, but HR beats per minute were kept constant in the target range, so no HR enhancement was used.…”

“…This study tested whether enhanced pulse oximeter sonifications would improve participants’ accuracy in identifying the HR and SpO 2 ranges of newborns in the first 10 minutes of life, compared to conventional sonifications. It is part of a program of research investigating ways to enhance the pulse oximetry tone to make clinically relevant ranges for neonatal SpO 2 and/or HR ranges more perceptually distinct (Deschamps et al, 2016; Hinckfuss et al, 2022; Hinckfuss et al, 2016; Zestic et al, 2019). Tremolo and formant enhancements were added to the conventional pulse oximeter sonification in a stepped mapping to mark out the low, target, or high ranges of HR and SpO 2 , respectively, where the actual SpO 2 values considered low, target, or high change with the number of minutes after birth.…”

“…Clinicians who are familiar with pulse oximeter auditory displays may perceive and process the enhancements differently from non-clinicians. However, studies by Paterson et al (2019) and Hinckfuss et al (2022) found no difference in range identification performance or other judgments between anesthetists and undergraduate students when tasked with monitoring changes in SpO 2 .…”

Objective Auditory enhancements to the pulse oximetry tone may help clinicians detect deviations from target ranges for oxygen saturation (SpO2) and heart rate (HR). Background Clinical guidelines recommend target ranges for SpO2 and HR during neonatal resuscitation in the first 10 minutes after birth. The pulse oximeter currently maps HR to tone rate, and SpO2 to tone pitch. However, deviations from target ranges for SpO2 and HR are not easy to detect. Method Forty-one participants were presented with 30-second simulated scenarios of an infant’s SpO2 and HR levels in the first minutes after birth. Tremolo marked distinct HR ranges and formants marked distinct SpO2 ranges. Participants were randomly allocated to conditions: (a) No Enhancement control, (b) Enhanced HR Only, (c) Enhanced SpO2 Only, and (d) Enhanced Both. Results Participants in the Enhanced HR Only and Enhanced SpO2 Only conditions identified HR and SpO2 ranges, respectively, more accurately than participants in the No Enhancement condition, ps < 0.001. In the Enhanced Both condition, the tremolo enhancement of HR did not affect participants’ ability to identify SpO2 range, but the formants enhancement of SpO2 may have attenuated participants’ ability to identify tremolo-enhanced HR range. Conclusion Tremolo and formant enhancements improve range identification for HR and SpO2, respectively, and could improve clinicians’ ability to identify SpO2 and HR ranges in the first minutes after birth. Application Enhancements to the pulse oximeter tone to indicate clinically important ranges could improve the management of oxygen delivery to the neonate during resuscitation in the first 10 minutes after birth.

The Preferred Reporting Items for Diagnostic Accuracy Studies in Endodontics (PRIDASE) 2024 guidelines are based on the Standards for Reporting of Diagnostic Accuracy Studies (STARD) 2015 guidelines and the Clinical and Laboratory Images in Publications (CLIP) principles, with the addition of items specifically related to endodontics. The use of the PRIDASE 2024 guidelines by authors and their application by journals during the peer review process will reduce the possibility of bias and enhance the quality of future diagnostic accuracy studies. The PRIDASE 2024 guidelines consist of a checklist containing 11 domains and 66 individual items. The purpose of the current document is to provide an explanation for each item on the PRIDASE 2024 checklist, along with examples from the literature to help readers understand their importance and offer advice to those developing manuscripts. A link to the PRIDASE 2024 explanation and elaboration document is available on the Preferred Reporting Items for study Designs in Endodontology (PRIDE) website (https://pride‐endodonticguidelines.org/pridase/) and on the International Endodontic Journal website (https://onlinelibrary.wiley.com/page/journal/13652591/homepage/pride‐guidelines.htm).
