Pressure injury is the most important issue facing paralysis patients and the elderly, especially in long-term care or nursing. A new interfacial pressure sensing system combined with a flexible textile-based pressure sensor array and a real-time readout system improved by the Kalman filter is proposed to monitor interfacial pressure progress in the cardiac operation. With the design of the Kalman filter and parameter optimization, noise immunity can be improved by approximately 72%. Additionally, cardiac operation patients were selected to test this developed system for the direct correlation between pressure injury and interfacial pressure for the first time. The pressure progress of the operation time was recorded and presented with the visible data by time- and 2-dimension-dependent characteristics. In the data for 47 cardiac operation patients, an extreme body mass index (BMI) and significantly increased pressure after 2 h are the top 2 factors associated with the occurrence of pressure injury. This methodology can be used to prevent high interfacial pressure in high-risk patients before and during operation. It can be suggested that this system, integrated with air mattresses, can improve the quality of care and reduce the burden of the workforce and medical cost, especially for pressure injury.

Background Each year, 2.6 million of pregnancies end as stillbirth. Recent literature began to understand parents’ traumatic experience in stillbirth and its profound impact on parents’ mental health and psychosocial effect. But there is little understanding on the actual care and disposal of the stillborn baby, nor is there an agreement on how hospitals should care for the stillborn baby to mitigate parents’ profound loss. The purpose of this study is to understand parents’ perspective on hospital’s care for their stillborn babies, hoping to make suggestions on how can hospitals improve their care to mitigate parents’ grieves. Methods A descriptive phenomenological approach was adopted and twenty couples (40 individuals) who had to decide how to care for the remains of their stillborn babies participated in the study. The data were collected through in-depth interviews, which involved semi-structured and open-ended questions. The phenomenological methods of Giorgi were applied to analyze the data. Results Parents felt unprepared and lack of support when they had to handle their stillborn babies’ remains. The research results revealed two major themes: 1) Handling stillborn babies remain ignorantly; 2) Pacifying the disturbed soul on both sides. Given stillbirth’s profound implication for parents’ identity and psychosocial role, hospitals need to be more sensitive and proactive to parents’ cultural and religious needs when they care for stillborn baby and handle its body. Conclusions It was found in the study that reflection and identification were the emerging themes, which can enable healthcare professionals to understand parents’ concerns in a meaningful way, as they deal with the remains of stillborn babies. Moreover, it is hoped that hospital administration and health care personnel should consider stillborn parents’ concerns and incorporate their needs into nursing assessment and treatment practices.
