A Study of Agreement Between Oxygen Saturation Measured by Two Probes in Infants on the Neonatal Unit
A study testing Oxygen saturation probe Mindray 520 N and Mindray 521 N in people with Neonatal Disease, run by University of Nottingham at 1 site in United Kingdom.
Trial summary
On the neonatal unit in Derby, two types of probes are in routine use: Mindray 520 N and Mindray 521 N. Feedback from parents and staff show that there are concerns that the two probes given very different oxygen saturation readings and, often, do not agree with each other. Read more about this study

About this study
On the neonatal unit in Derby, two types of probes are in routine use: Mindray 520 N and Mindray 521 N. Feedback from parents and staff show that there are concerns that the two probes given very different oxygen saturation readings and, often, do not agree with each other. This has raised concerns that infants' clinical care may be affected by the choice of probe. It is important to know if the two probes give similar results or not to ensure that infants get the appropriate monitoring and respiratory support as needed for good neonatal care. In this study, we will compare the reading made by the two probes and determine whether the readings of the two probes agree with each other and if any disagreement is such that clinical decision making is affected by the difference.
Read the detailed description
Continuous monitoring of oxygen saturation level is a key component of neonatal intensive care and NICE recommends that all neonatal services "ensure that systems are in place for preterm babies to have a target saturation level of 91% to 95%" and that this is monitored using "continuous pulse oximetry" (NICE Quality statement 4 in Quality Standard QS193: https://www.nice.org.uk/guidance/qs193/chapter/Quality-statement-4-Oxygen-saturation). Oxygen saturation monitoring is used to provide optimal respiratory support to preterm infants to ensure adequate oxygenation of tissues while preventing risks of conditions such as retinopathy of prematurity and bronchopulmonary dysplasia [1]. It is equally important in term born infants who require intensive care such as for determining adequate oxygenation for respiratory support and screening for congenital heart disease [2]. For these reasons, most infants in neonatal units are continuously monitored using pulse oximetry, a simple and painless test that measures blood oxygen levels by passing a small beam of light through the infant's hand or foot. This measures the changes in light absorption to calculate the levels of oxygenated and deoxygenated blood. To do this the light (or probe) has to be attached to the infant's hand or foot using a tie or a sticker. The probe must be attached firmly for the saturation monitor to pick up the correct readings. As neonatal skin is delicate and it is often difficult to stick objects to it, neonatal oxygen saturation probes are carefully designed. Many different types of saturation probes are in routine use in neonatal units. It is important to ensure that they give accurate and comparable readings. In the neonatal unit in Derby, two types of probes are in routine use: Mindray 520 N and Mindray 521 N. Feedback from parents and staff show that there are concerns that the two probes given very different oxygen saturation readings and, often, do not agree with each other. This has raised concerns that infants' clinical care may be affected by the choice of probe. It is important to know if the two probes give similar results or not to ensure that infants get the appropriate monitoring and respiratory support as needed for good neonatal care. In this study, we will compare the reading made by the two probes and determine whether the readings of the two probes agree with each other and if any disagreement is such that clinical decision making is affected by the difference.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Oxygen saturation probe Mindray 520 N and Mindray 521 NDevice
Two oxygen saturation probes will be used in this study:
Mindray 520 N is a disposable oxygen saturation sensor for neonates and adults. It is a disposable, single-use sensor that is wrapped around the infant's arm or foot. Its ends stick together giving a firm, close contact with the skin.
Mindray 521 N is another disposable oxygen saturation sensor for neonates and adults that is used on the neonatal unit in routine practice. As Mindray 520 N and 521 N are CE marked and used within their intended purposes we do not require a letter of no objection from the MHRA for that usage. The Mindray probes will be used without modification and there are no safety issues to the patient. Therefore, a letter of no objection from the MHRA is not required and this is not a medical device study under the Medical Devices Directive.

Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
oxygen saturation of babies using Minday 520 N and Minday 521 N (time frame: 12 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 8 Sep 2023; AzTrials last refreshed its copy on 6 Nov 2026.
