The pulse oximeter is a device that noninvasively provides continuous information about the peripheral oxygen saturation (SpO2) rate. This device is utilized in the detection of hypoxemia, due to its able to sense changes in hemoglobin oxygen saturation.
The objective of this study was to verify the accuracy of the Choice® Medical MD300C3 Fingertip Pulse Oximeter, as compared to that of a hospital oximeter coupled with a Drager® Infinity Delta monitor, with the purpose of using this first methodology in dental procedures to monitor the peripheral oxygen saturation (SpO2) of patients submitted to dental treatments.
Fifty-five adult patients, both genders, were selected in the Santa Casa Hospital of Maringa, Brazil. The volunteers did not present cardiac problems, prosthetic cardiac valves, pacemakers, or pulmonary diseases, and were not pregnant or children. Each patient received a portable fingertip pulse oximeter (PPO) on the middle finger of the left hand and the hospital oximeter (control device) on the forefinger of the same hand. A total of six measurements were developed. The Pearson correlation coefficient and the Bland and Altman method was used to calculate the statistical analysis.
No statistically significant difference was found between the measurements taken by the utilized devices. The average of comparative analysis presented by the devices was 0.2337 ± 0.4355 (mean ± SD), suggesting a strong correlation between the obtained results.
According to the methodology of the research, the PPO has similar accuracy to the conventional hospital oximeter with digital sensor. The PPO can be used in dental treatments.
脉搏血氧仪是一种能无创地提供外周血氧饱和度(SpO2)连续信息的设备。由于其能够感知血红蛋白氧饱和度的变化,该设备被用于低氧血症的检测。
本研究的目的是验证Choice® Medical MD300C3指尖脉搏血氧仪与配备Drager® Infinity Delta监护仪的医院血氧仪相比的准确性,目的是在牙科手术中使用这种首要方法来监测接受牙科治疗患者的外周血氧饱和度(SpO2)。
在巴西马林加的圣卡塔琳娜医院选取了55名成年患者,男女不限。志愿者无心脏问题、人工心脏瓣膜、起搏器或肺部疾病,且未怀孕或为儿童。每位患者左手中指佩戴便携式指尖脉搏血氧仪(PPO),同一只手的食指佩戴医院血氧仪(对照设备)。共进行了六次测量。采用Pearson相关系数和Bland-Altman方法进行统计分析。
所使用的设备测量结果之间未发现统计学上的显著差异。这些设备进行的比较分析平均值为0.2337±0.4355(均值±标准差),表明所获结果之间存在强相关性。
根据研究方法,PPO与传统的带数字传感器医院血氧仪具有相似的准确性。PPO可用于牙科治疗。
