Comparison the Precision of Ear and Finger Pulse Oximetry with Finger Sensor in Mechanically Ventilated ICU Patients

Abstract

Comparison the Precision of Ear and Finger Pulse Oximetry with Finger Sensor in Mechanically Ventilated ICU PatientsKeywords Oximetry; Arterial Oxygen Saturation; Intensive Care Units Aims Nowadays, the pulse oximetry is widely used to monitor the oxygen saturation constantly. In the clinical care, it is observed that the ear pulse oximetry with the finger sensor is sometimes utilized in the ICUs. The aim of the study was to determine the accuracy of the ear pulse oximetry and the fingertip with the finger sensor in the ICU patients under the mechanical ventilation. Materials & Methods In the analytic comparative study, 60 hospitalized patients under the mechanical ventilation in the ICU of Moddares Hospital in Kashmar Township were studied in 2015. The subjects were selected via available convenience sampling method. One finger pulse oximetry sensor having been attached to the upper part of the ear and the other to the fingertip, the arterial blood sampling was done simultaneously. Data was analyzed by SPSS 22 software using repeated ANOVA and Spearman correlation tests. Findings Mean oxygen saturation percentage and the heartbeat of ear, fingertip, and arterial blood pulse oximetry were significantly different (p<0.001). In addition, the oxygen saturation percentage of ear, fingertip, and arterial blood pulse oximetry was significantly correlated by the partial pressure of oxygen (PaO2; p=0.001). Nevertheless, the mentioned parameters were not significantly correlated by the peripheral edema and especially, by the hand (p>0.05). Conclusion The utilization of ear pulse oximetry with the finger sensor on the fingertip cannot lead to accurate results of the oxygen saturation in the hospitalized patients in the ICU under the mechanical ventilation. However, in case of any reduction in the arterial blood oxygen pressure, the accuracy of the finger pulse oximetry starts to drop out.

The effect of electronic error-reporting forms on nurse’s stress and the rate of error-reporting

“…However, it’s unclear if the anonymous electronic form would increase the nurses’ error-reporting rate and reduce their stress. Studies 36,37 have been carried out on error-reporting in the medical field, but so far no study has examined the effect of electronic error-reporting forms on the error-reporting rate and the stress level of individuals. The objective of this study was to examine the effect of electronic error-reporting forms on decreasing nurses’ stress and increasing their error-reporting rate.…”
