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: The aim of this study was to explore the effects of distance yoga learning in improving depression and pregnancy stress in pregnant women during the pandemic. Methods: A preference-based quasi-experimental study design with an experimental group (n = 30) and a control group (n = 31) was used to test both self-reported depression and stress status. The experimental group received a 12-week pregnancy yoga program, including one weekly 60 min distance yoga class followed by two sessions of DVD yoga exercise at home, while the control group received only routine nursing care. Results: There were significant differences in the depression and pregnancy stress indices between the two groups. As the number of weeks of pregnancy increased, both pregnancy depression and stress tended to gradually increase (p < 0.001). However, the experimental group had less pregnancy depression than the control group (p < 0.001), while there was no significant difference between the two groups in stress (p = 0.970). Conclusions: The findings inform clinical practice regarding the use of alternative exercise options such as distance yoga classes for pregnant women’s mental health during a pandemic to reduce depression and pregnancy stress.
