Background and aim: One of the most important technological advancements for monitoring patients -- especially in anesthesia, recovery, and Intensive Care stages -- is pulse oximetry which can measure the oxygen saturation of arterial blood (spo2) and show hypoxemia before it is clinically observable. Therefore, it is necessary for the individuals who are responsible for treating and taking care of patients in critical stages to have sufficient knowledge about it. If they lack the required knowledge, they should be trained using appropriate methods.

Materials and methods: Upon referring to the ORs and the ICUs, a questionnaire was distributed among the medical and paramedical staff (doctors, nurses, anesthesia technicians, etc.) to assess their knowledge of pulse oximetry. The questionnaire had a part for demographic data and 20 true/false items and was to be filled in by the subjects in 15 minutes. After the data were collected and analyzed, the subjects' level of knowledge about pulse oximetry was assessed in terms of age, sex, academic degree, their experience with the device, and how they had obtained information about pulse oximetry. The variable was measured on a 0-20 scale. The subjects would get one point for every correct response and the total number of correct responses would constitute each individual's score.

Results: The results of the study show that only 15.8% of the participants had a high level of knowledge of pulse oximetry. The figure was 61% for those having medium-level knowledge and 23.2% for the individuals with low knowledge. In other words, for the optimal use of the device, 84.2% of the subjects need training. The results also indicate that the subjects' level of knowledge is positively related to their sex, academic degree, and how they acquired their knowledge. In fact, female subjects, paramedical staff, and those who had obtained information from colleagues and the companies selling the device had a lower level of knowledge needed for using the device properly. However, no statistically significant difference was found between the subjects' knowledge of pulse oximetry and their age and experience with the device.

Conclusion: Based on the findings, it is necessary for the female members of paramedical staff to be trained in classes and/or be provided with pamphlets on the issue. 

Background and Aim : Creation of knowledge management (KM) and efforts to use it in the university research programs shows the university society activity to enhance intellectual qualities and improve this effectiveness of the universities on the development and advancement in the countries.

Background and Aim: Learning basic issues in nursing requires new strategies that can enhance knowledge retention among nurses. This study aimed to determine the effect of lecturing by peer-nurses on critical units nurses’ retaining knowledge of electrocardiogram (ECG) interpretation.

Materials and Methods: In this experimental study, two units (as test and control groups) were selected randomly from among critical care units of Semnan University of Medical Sciences hospitals. First, a pretest was performed on nurses in both groups. Then, the nurses of test group were trained by a peer-nurse how to interpret ECGs. A posttest was performed on the two groups both a week and a year later. Finally, the data were analyzed using Pearson’s correlation coefficient, t-paired and t-tests.

Results: The mean of nurses’ scores of ECG interpretation in pretest was 9.55±2.73 in the test group and 10.82±3.43 in the control group. In the first posttest, mean scores of nurses’ knowledge in test and control groups were 15.27±2.57 and 11.36±3.29, respectively. In the second posttest, nurses’ mean scores in test and control groups were 10.82±4.07 and 11.33±2.95, respectively. There was a significant difference (p<0.05) between the pretest and the first posttest in the test group, but there was no such difference for the second posttest (p>0.05).

Conclusion: Lecturing by peer-nurses can enhance nurses’ knowledge about ECG interpretation in the short run, but it cannot enhance knowledge retention. So it is suggested that other educational methods be used in nurses' in-service training programs designed for ECG interpretation.

Background and Aim: Considering the elements of knowledge management (availability, creation, and transfer of knowledge) is very important in digital libraries websites and makes the performance better. So this paper aim to identify the knowledge management criteria in Iranian selected digital library's websites and study of observance scale

Materials and Methods: The research method was descriptive survey and from applied research type. Data collecting has been based on check list according with K-ACT model (Knowledge- Access Creation Transfer).
