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… Expand
Improving the detectability of oxygen saturation level targets for preterm neonates: A laboratory test of tremolo and beacon sonifications.
TLDR
The Tremolo sonification may have advantages over the Beacon sonification for monitoring SpO2 of preterm neonates, but both must be further tested with clinicians in clinically representative scenarios, and with different levels of ambient noise and distractions. Expand
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. Expand
The effect of a secondary task on identification accuracy of oxygen saturation ranges using an enhanced pulse oximetry sonification
TLDR
This laboratory study explored the effect of a secondary task on participants’ ability to identify SpO2 range when using a conventional sonification (LogLinear sonification) versus an enhanced sonification with additional sound dimensions of tremolo and brightness (Stepped Effects sonification).

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. Expand

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. Expand
Evaluation of an enhanced pulse oximeter auditory display: a simulator study.
TLDR
The enhanced auditory display helps anaesthetists judge SpO2 levels more effectively than current auditory displays and may facilitate 'eyes-free' monitoring. Expand
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. Expand
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.

TLDR
The enhanced auditory display supports more accurate detection of target transitions and identification of SpO2 range for both clinicians and nonclinicians. Expand
A comparison of two designs for earcons conveying pulse oximetry information.
TLDR
Overall, pitch-earCons may provide a better intermittent auditory pulse oximetry display than timbre-earcons, especially for clinical contexts when quiet is needed. Expand

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. Expand
Achieving targeted pulse oximetry values in preterm infants in the delivery room.
TLDR
SpO₂ values were maintained within a specified target range for significantly longer in preterm neonates resuscitated using the TOTS display compared with those resuscitated without TOTS. Expand
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. Expand
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. Expand
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. Expand
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. Expand

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. Expand

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. Expand
