Summary: Standard pulse oximeter auditory tones do not clearly indicate departures from the target range of oxygen saturation in preterm neonates. Acoustically enhanced tones significantly improve clinicians' and non-clinicians' ability to identify the SpO2 range. The accuracy of range identification was higher in the enhanced conditions compared to the standard condition, with the tremolo-enhanced tones showing the highest accuracy.

Summary: The COVID-19 Oximetry@Home services allow higher-risk patients with mild symptoms to monitor their oxygen saturation at home, but factors impacting SpO(2) readings may affect the accuracy of clinical decisions.

Summary: Similar to other organs, the retina relies on tightly regulated perfusion and oxygenation, and various eye and systemic diseases have been shown to affect retinal blood flow. While peripheral oxygen saturation measurement has become a standard clinical measurement, developing a noninvasive technique to measure retinal oxygen saturation remains challenging. Current retinal oximetry technology is inadequate for reliable clinical use, but newer technologies and approaches are being developed for the future.

Summary: This study evaluated the clinical feasibility of a novel continuous physiological monitoring technology in African healthcare facilities. The results showed that the technology performed well in monitoring heart rate and temperature, but had relatively poor performance in monitoring respiratory rate and oxygen saturation.

Summary: Pulse oximetry is widely used in primary and intensive care units, especially during the COVID-19 pandemic. However, factors such as skin color can affect its accuracy. Recent studies have found a positive bias in oxygen saturation measurements in patients with darkly pigmented skin. This review aims to assess the influence of skin pigmentation on the accuracy of pulse oximetry through a systematic review.

Summary: The study aimed to investigate the age-related variation of blood oxygen saturation from the dental pulp during different stages of tooth development in children. The results showed that blood oxygen saturation tended to decrease with age progression, and there were significant differences between different tooth types and clinical conditions.

Summary: Cerebral hypoxia, caused by oxygen deprivation to the brain, increases the risk for neurological disorders. Early recognition of hypoxia is crucial for better outcomes. Photoacoustic imaging can measure brain oxygen saturation through spectroscopic analysis.

Summary: Blood oxygen saturation is an important clinical parameter for postoperative hospitalized patients. Current monitoring methods, such as arterial blood gas and pulse oximetry, are not suitable for long-term continuous monitoring. Recent technological advances in consumer-grade fitness trackers could potentially fill this gap, but their applicability and accuracy in hospitalized patients have not been well studied.

Summary: This study aims to assess disparities in hypoxemia detection using pulse oximetry among self-identified racial groups and its associations with clinical outcomes. The study found that black patients were more likely to experience occult hypoxemia compared to white patients and that occult hypoxemia was associated with increased mortality.

Summary: Current guidelines recommend using a cardiac monitor during neonatal resuscitation. Infants assigned to a novel electrocardiogram algorithm had a faster heart rate compared to the conventional algorithm. Although the resuscitation outcomes did not differ, the availability of an earlier heart rate may be beneficial for neonatal providers during high-risk resuscitations.

Summary: Assessing the vitality of fetal and neonatal bovine cattle is crucial for preventing stillbirths. Accurate diagnosis of fetal and neonatal vitality is essential for prompt and effective treatment. Options for obstetric assistance or resuscitation methods should be considered depending on when the asphyxia occurs. However, practical tools for evaluating newborn calf vitality with high accuracy and user-friendliness are yet to be developed.

Summary: This study found that the pharynx is an accurate site for measuring SpO2 in shocked patients. The results showed that the pharyngeal SpO2 had a bias of less than 0.5% with high precision. Additionally, this method had high sensitivity and specificity in detecting mild and severe hypoxemia.

Summary: Continuous monitoring of arterial oxygen saturation by pulse oximetry is crucial for respiratory support in neonates, but the presence of fetal hemoglobin may affect the accuracy of readings. Studies show that an increase in HbF can alter the relationship between partial oxygen pressure and SpO2 due to the leftward shift in the oxygen dissociation curve.

Summary: Melanin and oxy/deoxy-hemoglobin are the major optical absorbers in tissue. The impact of skin tone and pigmentation on biomedical optics is not well understood. This study investigated the effects of skin tone on photoacoustic signal generation, depth penetration, and oximetry, and proposed a simple compensation method.
