    Quick on-scene assessment and early intervention is the key to reduce the mortality of stroke and trauma patients, and it is highly desirable to develop ambulance-based diagnostic and monitoring devices in order to provide additional support to the medical personnel. We developed a compact and low cost ultra wideband noise sensor for medical diagnostics and vital sign monitoring in pre-hospital settings. In this work, we demonstrated the functionality of the sensor for respiration and heartbeat monitoring. In the test, metronome was used to manipulate the breathing pattern and the heartbeat rate reference was obtained with a commercial electrocardiogram (ECG) device. With seventeen tests performed for respiration rate detection, sixteen of them were successfully detected. The results also show that it is possible to detect the heartbeat rate accurately with the developed sensor

    P04.41 Exploring reasons for and outcomes of second stage caesarean section and assisted vaginal birth in selected hospitals in Kenya

    Objective: Obstetric vacuum devices for assisted vaginal birth (AVB) can avoid the need for unnecessary second-stage caesarean sections (SSCS), associated with increased morbidity and mortality. Despite emergency obstetric training since 2019, AVB was rarely performed. This study sought to better understand missed opportunities and reasons for non-performance of AVB in Kenya. Method: A mixed-methods design incorporated a review of randomly selected SSCS and AVB case notes, and key informant interviews with healthcare providers, from 8 purposively selected, high-volume hospitals in Kenya. The reviews were carried out by four experienced obstetricians (3 Kenyan, 1 British). The interviews were semi-structured and conducted online and analysed using a thematic approach. Results: Six AVB and 66 SSCS cases were reviewed. Nine percent of SSCS could have been AVB, and 58% reviewers were unable to determine appropriateness due to poor record keeping. Perinatal mortality was 9%, and 11% of infants and 9% of mothers experienced complications following SSCS. Twenty interviews, with obstetricians, midwives and medical officers, explored themes of previous experience, confidence, and adequacy of training relating to AVB. Reasons for non-performance included lack of equipment and staff. Conclusion: Increases in appropriate use of AVB could save the lives of infants and mothers and reduce ongoing morbidity. In order to achieve this, the varied reasons for non-performance of AVB need to be systematically addressed at local, regional and national levels

    P14.02 An electronic behaviour diary: Monitoring the effects of advanced obstetric surgical skills training

    Objective: Training should lead to improvements in the quality of clinical care delivery. It is essential to follow up participants after a training intervention to monitor changes in behaviour associated with adoption of lessons learned into clinical practice. We introduced an electronic diary to facilitate monitoring whilst minimising effort for participants. Method: An electronic diary was created using a freely available on-line platform. Following a training intervention on advanced obstetric surgical skills, obstetric residents from Kenya were invited to pilot completing the diary after their labour ward shifts. Entries were anonymised. Participants were asked to enumerate the times they utilised specific skills, or to state why they had been unable to do so, using tick box options. Reflections on skills used were entered using free comments. Results: All participants reported changed behaviours, for example, improved surgical knot-tying, safer needle handling, separate closure of uterine incision angles and techniques for delivery of the impacted fetal head. 6 reported conducting vaginal breech birth and 6 performed vacuum-assisted birth. All reported improvements in use of the safe surgical checklist, obtaining consent and respectful maternity care. 7 had participated in newborn resuscitation. Reflections suggested participants experienced improved levels of confidence and satisfaction when implementing new skills. Conclusion: This pilot study has demonstrated the feasibility of monitoring clinical behaviour change following training using an electronic platform. Monitoring the effect of training is essential to prove that training results in improvements to clinical practice. We plan to roll out this intervention following future training interventions

    Tracking the Temporal-Evolution of Supernova Bubbles in Numerical Simulations

    The study of low-dimensional, noisy manifolds embedded in a higher dimensional space has been extremely useful in many applications, from the chemical analysis of multi-phase flows to simulations of galactic mergers. Building a probabilistic model of the manifolds has helped in describing their essential properties and how they vary in space. However, when the manifold is evolving through time, a joint spatio-temporal modelling is needed, in order to fully comprehend its nature. We propose a first-order Markovian process that propagates the spatial probabilistic model of a manifold at fixed time, to its adjacent temporal stages. The proposed methodology is demonstrated using a particle simulation of an interacting dwarf galaxy to describe the evolution of a cavity generated by a Supernov
