Objective We aimed to test whether the use of novel pulse oximetry sounds (sonifications) better informs listeners when a neonate’s oxygen saturation (SpO2) deviates from the recommended range. Background Variable-pitch pulse oximeters do not accurately inform clinicians via sound alone when SpO2 is outside the target range of 90% to 95% for neonates on supplemental oxygen. Risk of blindness, organ damage, and death increase if SpO2 remains outside the target range. A more informative…

Effectiveness of enhanced pulse oximetry sonifications for conveying oxygen saturation ranges: a laboratory comparison of five auditory displays

TLDR
Enhanced sonifications are more informative than conventional sonification and might allow anaesthetists to judge better when desaturation decreases below, or returns to, a target range.

Enhanced Neonatal Pulse Oximetry Sounds for the First Minutes of Life: A Laboratory Trial.

TLDR
Auditory enhancements to the pulse oximetry tone may help clinicians detect deviations from target ranges for oxygen saturation (SpO2) and heart rate (HR) and could improve clinicians' ability to identify SpO2 and HR ranges in the first minutes after birth.

Signaling Patient Oxygen Desaturation with Enhanced Pulse Oximetry Tones.

Manufacturers could improve the pulse tones emitted by pulse oximeters to support more accurate identification of a patient's peripheral oxygen saturation (SpO2) range. In this article, we outline

Smooth or Stepped? Laboratory Comparison of Enhanced Sonifications for Monitoring Patient Oxygen Saturation

TLDR
The stepped-effects display has more pronounced auditory cues at SpO2 range transitions, from which participants can better infer absolute SpO1 value, and further development of a smooth- effects display is not necessary.

TLDR
In a laboratory study it was tested if participants could differentiate between seven ranges of oxygen saturation using the proposed psychoacoustic sonification, and on average participants could identify in 84% of all cases the correct SpO2 range.

The effectiveness of pulse oximetry sonification enhanced with tremolo and brightness for distinguishing clinically important oxygen saturation ranges: a laboratory study

TLDR
Participants can identify clinically meaningful oxygen saturation ranges and detect threshold transitions more accurately with enhanced sonification than with conventional sonification.

Design And Evaluation of a New Auditory Display for the Pulse Oximeter

TLDR
Compared auditory displays based on current pulse oximeters with displays designed to provide more information about SpO2 levels using additional acoustic properties show that the new auditory displays support better identification of specified ranges ofSpO2, and better detection of when saturation transitions a critically relevant threshold.

Comparison of Standard and Enhanced Pulse Oximeter Auditory Displays of Oxygen Saturation: A Laboratory Study With Clinician and Nonclinician Participants.

TLDR
The enhanced auditory display supports more accurate detection of target transitions and identification of SpO2 range for both clinicians and nonclinicians.

Novel Pulse Oximeter Sonification Mappings: Improving Oxygen Saturation Monitoring for Vulnerable Neonates

TLDR
If monitoring SpO2 can be improved by redesigning the auditory component of pulse oximeters, using novel sonification mappings is explored, suggesting that this clear and distinct auditory marker could be applied in the challenging monitoring environment of neonatal inter-hospital retrieval.

Melodic algorithms for pulse oximetry to allow audible discrimination of abnormal systolic blood pressures

TLDR
Three melodic algorithms were developed to apply tonal and rhythmic variations to the continuous pulse oximeter tone, dependent on the systolic blood pressure, and these algorithms distort the original audible pattern minimally, to facilitate comprehension of both the underlying pattern and the applied variations.

How Well Can Anaesthetists Discriminate Pulse Oximeter Tones?

TLDR
While qualitative estimate changes in oxygen saturation are moderately reliable, quantitative estimation is severely limited by a compromised perceived scale and may lead to underestimation of the severity if the auditory signal is relied on in isolation.

Effects of Divided Attention and Operating Room Noise on Perception of Pulse Oximeter Pitch Changes: A Laboratory Study

TLDR
Efforts to reduce distractors and decrease background noise should be considered during induction and emergence, periods of especially high risk, when anesthesiologists has to attend to many tasks and are thus susceptible to error.

The Sounds of Saturation

TLDR
Anesthesiologists should familiarize themselves with the audible frequency scale of a particular pulse oximeter model before its use, to ensure the ability to accurately determine oxygen saturation from a pulse tone may be hindered.

Transcribed oxygen saturation vs oximeter recordings in very low birth weight infants

TLDR
Transcribed SpO2 values overdocumented target range and underdocumented hyperoxemic and hypoxemic ranges compared with electronic oximeter data support incorporating electronic oximeters data into medical records.

A Novel Sonification Strategy for Auditory Display of Heart Rate and Oxygen Saturation Changes in Clinical Settings

TLDR
The described sonification strategy may effectively communicate information about current heart rate and oxygen saturation status relative to desired target levels and can be applied to clinical monitoring settings in which a stream of discrete auditory informational items is indicated.

Can people hear the pitch change on a variable-pitch pulse oximeter?

TLDR
A computer program was created to simulate the pitches that accompanied various oxygen saturations and suggested four alternative designs that may prove beneficial to a group of individuals who have been unable to detect a change in pitch when oxygen saturation changes.

Sonification Supports Eyes-Free Respiratory Monitoring and Task Time-Sharing

TLDR
Overall, sonification of patient physiology beyond traditional pulse oximetry appears to be a viable and useful adjunct to visual monitors.
