THE LIVED EXPERIENCE OF SECOND VICTIM CRNAs

A second victim is a health care provider who has been involved in a critical event. A critical event is a clinical situation in which an unforeseen clinical outcome occurs, or the clinical deterioration of the patient takes place for many different reasons. The patient and his/her family are the first victims. The health care provider(s) involved in the event are second victims. After such an event, the healthcare provider may experience a constellation of negative emotions, such as guilt, sadness, depression, somatic symptoms, hypervigilance, and fear. Most second victims require support to cope with the adverse clinical situation. Second victims, their need for support, and methods of assistance are studied in this integrative review. Many of the studies addressed in this integrative review, revealed that having a trusted colleague or staff member with whom to discuss the critical event is therapeutic. Some organizations have developed programs to support second victims in which specially trained staff members are deployed to discuss critical events with those involved, if the participant(s) desire the support. Other clinical facilities do not have established support programs; however healthcare providers have expressed desire to discuss the event in order to gain perspective, understand why it happened, and sometimes just to ventilate about it

Covid-19 as an Incubator Leading to Telemedicine Usage: KM Success Factors in Healthcare

Virtual hospitals offer a platform for healthcare workers to share knowledge, treat patients equally everywhere and, thus, reduce patient mortality rates. Such platforms include different technologies, for example telemedical applications. The use of these technologies and the need to get specific knowledge on the patients’ treatment was reinforced in the past years due by Covid-19. Not only the treatment of Covid-19, but also that of other diseases can be improved by increased technology use. By incorporating the KM success model, we will identify KM success factors leading to the use of virtual hospitals. This research observes the KM success model in the context of the low-digitalized field of healthcare. Consequently, we evaluate how the existing KM success model needs to be adjusted according to the peculiarities of healthcare

Matrix converters for sensorless control of PMSMs and other auxiliaries on deep-sea ROVs

The use of matrix converter technologies for the control of actuators and other auxiliaries onboard work-class, deep-sea, remotely operated vehicles (ROVs) is reported. Key requirements for such systems are the ability to sustain operation at high ambient pressures, up to 300 bar, commensurate with operation of ROVs at depths of 3000 m, and to minimise the number of external connections and cabling mass to improve reliability and reduce drag. Emphasis is given to 32 matrix converters for 3f–1f AC voltage/frequency for conversion control of system auxiliaries, with experimental results showing circuit functionality during pressure cycling consistent with typical operational duties, and the use of 33 matrix converters for control of actuators driven by brushless permanent magnet synchronous machines (PMSMs). A principal feature of the paper is the development of model-based sensorless control methodologies for driving PMSMs using matrix converters. In particular, it is shown that observer-based state estimation techniques normally employed for sensorless control of PMSMs using voltage source inverters, can be readily exported to matrix converter counterparts with minimal additional computational overhead. Experimental results from a 0.7 kW PMSM driven by a matrix converter, suitable for a subsea actuator pump, are included to demonstrate the ability of the sensorless techniques to provide reliable estimates of machine rotor position under transient load conditions, and the subsequent exploitation for matrix converter/motor combinations is discussed

Electrowetting controlled non-volatile integrated optical switch

We present the proof of concept of the first non-volatile bistable fiber optic switch combining integrated optics and electrowetting-actuated microfluidics. Design and realization of both EWOD and photonic layer are presented and successful switching of a 2×4 network is demonstrated
