“…A study involving 55 dental patients in Brazil found no statistically significant difference between a portable fingertip oximeter and hospital pulse oximeters. [29] The non-invasive SpO 2 of each device was measured by simultaneous application of the fingertip probe at six time intervals during the dental procedures. Although this study was conducted in a clinical setting, it included insufficient comparisons for a Bland-Altman analysis, and the Pearson correlation coefficient reported is not an appropriate method for equipment comparison.…”

Background. Low-cost, portable fingertip pulse oximeters are widely available to health professionals and the public. They are often not tested to International Organization for Standardization standards, or only undergo accuracy studies in healthy volunteers under ideal laboratory conditions. Objectives. To pragmatically evaluate the agreement between one such device and a conventional bedside pulse oximeter in a clinical setting, in patients with varied comorbidities and skin pigmentations. Methods. A single-centre equipment comparison study was conducted. Simultaneous measurements were obtained in 220 patients with both a Contec CMS50D Fingertip Pulse Oximeter and a Nihon Kohden Life Scope MU-631 RK conventional bedside monitor. Peripheral oxygen saturations (SpO 2) and pulse rates were documented, and patients' skin tone was recorded using the Fitzpatrick scale. Data were assessed using a Bland-Altman analysis with bias, precision and limits of agreement (LOA) calculated with 95% confidence intervals (CIs). A priori acceptability for LOA was determined to be 3%, in keeping with international standards. Results. The mean difference (therefore bias) between the conventional and fingertip oximeters for all data was-0.55% (95% CI-0.73-0.36). Upper and lower limits of agreement were 2.16% (95% CI 1.84-2.47) and-3.25% (95% CI-3.56-2.94). Regression analysis demonstrated worsening agreement with decreasing SpO 2. When samples were separated into 'normal' (SpO 2 ≥93%) and 'hypoxaemic' (SpO 2 <93%) groups, the normal range displayed acceptable agreement between the two oximeters (bias-0.20% with LOA 2.20-2.27), while the hypoxaemic group fell outside the study's a priori limits. Heart rate measurements had a mean difference of-0.43 bpm (LOA-5.61-4.76). The study was not powered to detect differences among the skin tones, but demonstrated no trend for this parameter to alter the SpO 2 measurements. Conclusions. During normoxia, portable fingertip pulse oximeters are reliable indicators of SpO 2 and pulse rates in patients with various comorbidities in a pragmatic clinical context. However, they display worsening agreement with conventional pulse oximeters during hypoxaemia. Skin tones do not appear to affect measurements adversely.

“…Numerosos autores se han planteado la duda acerca de la eficacia de los diferentes oxímetros del mercado, muchos de los cuales encuentran gran proximidad entre los datos de los dispositivos testeados, donde los valores mínimos y máximos en ocasiones no coinciden, pero mostrando diferencias menores al 3% y sin diferencias estadísticamente significativas 12,13 . Utilizando el método de Bland-Altman para comparar ambos dispositivos, se verificó la proximidad de cero en los valores encontrados.…”

Introducción. La oximetría de pulso constituye una manera no invasiva, rápi da y económica para determinar la oxigenación de los pacientes. Actualmente, existen numerosos dispositivos disponibles, aunque con pocas certezas respec to de la supervisión de su precisión. El objetivo de este estudio fue compa rar las mediciones de dos saturómetros de pulso para evaluar la concordan cia en pacientes con patología pulmonar utilizando la cooximetría como téc nica de referencia. Materiales y métodos. Estudio retrospectivo entre 2016 y 2017. Se incluyeron pacientes con indicación para la toma de gases arteriales entre 18 y 80 años y se excluyeron pacientes en asistencia respiratoria mecánica o con requerimien to de ventilación no invasiva. Se calculó sensibilidad y especificidad de PG para los pacientes que desaturan o no, según un punto de corte establecido en 93% por los gases en sangre. Resultados. Se incluyeron 147 pacientes de los cuales 102 tuvieron una satura ción mayor a 93% y 45 menor a 93%, que fueron considerados como pacientes con desaturación. No hubo diferencias significativas entre los saturómetros 1 y 2 en comparación con los gases en sangre (93.1±3.7 y 94.5±3.5 vs. 94.1±3.5, respectivamente). El BlandAltman entre ambos instrumentos de diagnóstico mostró un sesgo entre −4.8 y 1.7, y el grado de acuerdo entre los saturóme tros 1 y 2 fue >80%. Conclusión. En concordancia con otros estudios, nuestros resultados sugieren una correlación entre los dos oxímetros estudiados en la monitorización de las constantes vitales de los pacientes con patología respiratoria.

“…According to various studies, youngsters in developed nations are increasingly aware of the need for dental care, and more people are seeking out procedures to improve their oral health. (9,10). Dental surgical procedures can take a while and involve the use of local anaesthetics, which can cause anxiety and behavioural problems.…”

Comparative Evaluation of Effect of Endodontic Procedures on Peripheral Oxygen Saturation Levels and Pulse Rate Based on Age and Gender

Pulse oximetry is a non-invasive, indirect, continuous and cheap method of monitoring and evaluating the peripheral oxygen saturation in a clinical setting. Operative dental procedures involving the patient often involve fear and anxiety which may lower the oxygen saturation in the blood resulting in hypoxia. This current study aimed to evaluate the effects of invasive and non-invasive treatment modalities on the peripheral oxygen saturation using a reproducible and standardized method. This cross-sectional study was conducted in the department of Conservative dentistry and Endodontics. The study participants consisted of a total number of 100 patients aged 18-60-years who visited clinics for routine Endodontic procedures. The treatment was carried out by various endodontists in the clinic while pulse rate, SpO2 values of these patients were noted by the single operator. The oxygen saturation and pulse rate was assessed using the Pulse oximeter. A total of 100 patients were seen, 20 for each of the procedures. Mean age for the children was 25.5 ± 0.9 years for restorative procedures ; 41.7 ± 0.4 years for single visit RCT ;45.3 ± 0.9 years for multi visit RCT ; 37.0 ± 0.5 years for post endodontic procedures and 42.4 ± 0.6 years for full veneer crown procedures. Many individuals may experience stress and systemic disruptions as a result of the use of local anaesthetics and the execution of significant dental treatments. Monitoring can therefore help the dentist determine whether any emergency treatments or preventive measures were effective.
