AbstractRecently, maintaining a certain oxygen saturation measured by pulse oximetry (SpO2) range in mechanically ventilated patients was recommended; attaching the INTELLiVENT-ASV to ventilators might be beneficial. We evaluated the SpO2 measurement accuracy of a Nihon Kohden and a Masimo monitor compared to actual arterial oxygen saturation (SaO2). SpO2 was simultaneously measured by a Nihon Kohden and Masimo monitor in patients consecutively admitted to a general intensive care unit and mechanically ventilated. Bland–Altman plots were used to compare measured SpO2 with actual SaO2. One hundred mechanically ventilated patients and 1497 arterial blood gas results were reviewed. Mean SaO2 values, Nihon Kohden SpO2 measurements, and Masimo SpO2 measurements were 95.7%, 96.4%, and 96.9%, respectively. The Nihon Kohden SpO2 measurements were less biased than Masimo measurements; their precision was not significantly different. Nihon Kohden and Masimo SpO2 measurements were not significantly different in the “SaO2 < 94%” group (P = 0.083). In the “94% ≤ SaO2 < 98%” and “SaO2 ≥ 98%” groups, there were significant differences between the Nihon Kohden and Masimo SpO2 measurements (P < 0.0001; P = 0.006; respectively). Therefore, when using automatically controlling oxygenation with INTELLiVENT-ASV in mechanically ventilated patients, the Nihon Kohden SpO2 sensor is preferable.Trial registration UMIN000027671.

Pulse Oximeters

Small pulse oximeters have become widely available and can be useful for noninvasive monitoring of blood oxygen saturation by nonmedical personnel. When training control of breathing, an oximeter helps to reassure clients who hyperventilate that their oxygenation is adequate, offsetting their perception that they are not getting enough air. Low saturation may indicate a medical condition that impairs oxygen absorption. In that case, hyperventilation is a biological compensation that should not be tampered with.

The Way

The pandemic has led to an increase in the use of pulse oximetry to assess and manage patients with COVID-19 disease. Paul Silverston explains the principles of pulse oximetry and the factors that can affect the reliability and accuracy of readings Pulse oximetry is performed to detect and quantify the degree of hypoxia in patients with respiratory symptoms and illnesses, including patients with COVID-19 disease. Pulse oximeters are non-invasive, simple to use and inexpensive, but it is important to know how to interpret the readings in the context of the patient's symptoms and the other clinical findings. In COVID-19 disease, very small differences in the oxygen saturation reading result in significant differences in the way that the patient is managed, so it is important to be aware of the factors that can affect these readings. It is also important to appreciate that a low reading in a patient with suspected or confirmed COVID-19 disease may be the result of another disease process.

AbstractIntroduction:Pulse-oximetry has proven clinical value in Emergency Departments and Intensive Care Units. In the prehospital environment, oxygen is given routinely in many situations. It was hypothesized that the use of pulse oximeters in the prehospital setting would provide a measurable cost-benefit by reducing the amount of oxygen used.Methods:This was a prospective study conducted at 12 ambulance stations (average transport times >20 minutes). Standard care protocols and paramedic assessments were used to determine which patients received oxygen and the initial flow rate used. Pulse-oximetry measurements (oxygen-saturation measured by pulse oximetry) were then taken. If oxygen-saturation measured by pulse oximetry fell below 92% or rose above 96% (except in patients with chest pain), oxygen (O2) flow rates were adjusted. Costs of oxygen use were calculated: volume that would have been used based on initial flow rate; and volume actually used based on actual flow rates and transport time.Methods:A total of 1,907 patients were recruited. Oximetry and complete data were obtained on 1,787 (94%). Of these, 1,329 (74%) received O2 by standard protocol: 389 (27.5%) had the O2 flow decreased; 52 had it discontinued. Eighty-seven patients (6%) not requiring O2 standard protocol were hypoxemic (oxygen-saturation measured by pulse oximetry < 92%) by oximetry, and 71 patients (5%) receiving oxygen required flow rate increases. Overall, O2 consumption was reduced by 26% resulting in a cost-savings of $0.20 / patient. Prehospital pulse-oximetry allows unncessary or excessive oxygen therapy to be avoided in up to 55% of patients transported by ambulance and can help to identify suboptimally oxygenated patients (11%).Conclusion:Rationalizing the O2 administration using pulse-oximetry reduced O2 consumption. Other health care savings likely would result from a reduced incidence of suboptimal oxygenation. Oxygen cost-saving justifies oximeter purchase for each ambulance annually where patient volume exceeds 1,750, less frequently for lower call volumes, or in those services where the mean transport time is less than the 23 minute average noted in this study.

Abstract BACKGROUND Oxygen saturation monitoring (OSM) is a key aspect of clinical care in paediatric patients with acute respiratory disease. It is commonplace in the assessment of children with bronchiolitis, asthma and pneumonia and serves as a proxy for illness severity. However, there is a paucity of standardized guidelines around appropriate pulse oximetry and OSM use in these patients. Some preliminary evidence shows that intermittent pulse oximetry is as safe as continuous oximetry monitoring in children with bronchiolitis. Furthermore, inappropriate OSM may lead to overdiagnosis and overtreatment of mild hypoxia with no demonstrable clinical improvement and therefore contribute to prolonged length of stay. OBJECTIVES As part of The Choosing Wisely campaign, our aim is to increase the appropriate use of OSM in paediatric inpatients with asthma, bronchiolitis or pneumonia in our center to 90% by April 2018. DESIGN/METHODS Appropriate monitoring is defined as intermittent OSM when a patient is off oxygen for &gt;2 hours and continuous OSM whilst the patient is receiving supplemental oxygen. A 4 week pre-intervention baseline chart review showed 62% (23/37) had appropriate OSM. Series of interventions along the hierarchy of effectiveness were then chosen to improve the main outcome measure: • Educational sessions oriented at medical and nursing staff were provided to guide evidence-based practice and to reinforce the use of specific orders around OSM; • Visual cues were used in strategic locations to remind medical staff of appropriate OSM and to prompt discussion during ward rounds; • Weekly reminders and performance updates were displayed and electronically circulated to medical and nursing staff. Post-intervention data collection occurred via convenience sampling by project leaders from December 2017 to April 2018. A PDSA cycle approach was used to modify interventions. RESULTS OSM appropriateness increased to 78% (56/72) in the first 4 weeks post-initial interventions. There were no negative impacts on balancing measures. We anticipate an ongoing graded increase in appropriateness across the study period triggered by collective staff awareness and synergistic interventions. CONCLUSION This QI initiative will improve the appropriate use of OSM in patients admitted for bronchiolitis, pneumonia or asthma at our paediatric tertiary hospital without increasing the number of patient safety events or admissions to the intensive care unit. Further interventions are planned to ensure greater uptake and sustainability.
