Abstract
The Nurses Professional Values Scale-3 (NPVS-3) is a psychometric instrument derived from a set of values initially established by the American Nurses Association (ANA) Code of Ethics. The present study evaluates the reliability of the NPVS-3 scale for nursing students and nurses in Austria.
Methods
A cross-sectional methodological study was conducted on 209 research participants, comprising 139 nursing students and 70 nurses, with the objective of determining the reliability of the Austrian version of the scale. A multilevel approach was employed in the study, encompassing cultural and linguistic validation, content validity, face validity, and construct validity. The scale translation was performed per the established translation stages of back-translation and was subsequently reviewed by an expert committee. The translated instrument was applied to the participants who completed an online survey between April and July 2023. Internal consistency was evaluated using Cronbach’s alpha, while construct validity was assessed using confirmatory factor analysis (CFA).
Results
The Cronbach’s alpha values obtained were deemed appropriate, with the following results: Caring (0.852), Activism (0.832), and Professionalism (0.676). Through factorial analysis, three factors were identified as original NPVS-3 and construct validity was verified.
Conclusion
The Austrian version of the NPVS-3 demonstrated satisfactory validity, efficiently evaluating the professional values of nurses and nursing students in Austria.

Objective
Performing cardiopulmonary resuscitation (CPR) inevitably causes significant physical, as well as psychological stress for rescuers. Physical activity at high altitude, a hypobaric and hypoxic environment, similarly adds to the level of stress and causes multiple physiological changes. Continuous measurement of pulse rate serves as an objective measure of fatigue during CPR. We therefore aimed to investigate rescuers’ heart rates as a measure of physical strain during CPR in a high-altitude alpine environment to provide a better understanding of the physiological changes under these very special conditions.
Methods
Twenty experienced mountaineers performed basic life support (BLS) on a manikin for 16 min, both at baseline altitude and at high altitude (3454 m) following a quick and exhausting ascent over 1200 m. Sequence of scenarios was randomised for analysis. Heart rate was continuously measured and compared between baseline and high altitude by absolute differences and robust confidence intervals.
Results
During CPR at baseline, the average heart rate increased from 87 bpm (SD 16 bpm) to 104 bpm [increase 17 bpm (95% CI 8.24–24.76)], compared to an increase from 119 bpm (SD 12 bpm) to 124 bpm [increase 5 bpm (95% CI − 1.59 to 12.19)] at high altitude [difference between two groups 32 bpm (95% CI 25–39)]. Differences between periods of chest compressions and ventilations were very similar at baseline [19 bpm (95%CI 16.98–20.27)] and at high altitude [20 bpm 95% CI 18.56–21.44)], despite starting from a much higher level at high altitude. The average heart rates of rescuers at high altitude at any point were higher than those at baseline at any other point.
Conclusions
Performing BLS CPR causes exhaustion both at base level and at a high altitude. A further increase during CPR might imply a physiological reserve for adapting to additional physical exertion at high altitude. Phases of ventilation are much needed recovery-periods, but heart rates remain very high. Subjective measures of exhaustion, such as the BORG-scale, might lead to rescuers’ overestimation of their own performance.
