Pelvic Circumferential Compression Devices (PCCDs), an important medical device when caring for patients with pelvic fractures, play a crucial role in the stabilization and reduction of the fracture. During pelvic fracture cases, control of internal bleeding through access to the femoral artery is of utmost importance. Current designs of PCCDs do not allow vital access to this artery and in attempts to gain access, medical professionals and emergency care providers choose to cut into the PCCDs or place them in suboptimal positions with unknown downstream effects. We researched the effects on surface pressure and the overall pressure distribution created by the PCCDs when they are modified or placed incorrectly on the patient. In addition, we investigated the effects of those misuses on pelvic fracture reduction, a key parameter in stabilizing the patient during critical care. We hypothesized that incorrectly placing or modifying the PCCD will result in increased surface pressure and decreased fracture reduction. Our mannequin studies show that for SAM Sling and T-POD, surface pressure increases if a PCCD is incorrectly placed or modified, in support of our hypothesis. However, opposite results occurred for the Pelvic Binder, where the correctly placed PCCD had higher surface pressure when compared to the incorrectly placed or modified PCCD. Additionally, pressure distribution was significantly affected by the modification of the PCCDs. The cadaver lab measurements show that modifying or incorrectly placing the PCCDs significantly limits their ability to reduce the pelvic fracture. These results suggest that while modifying or incorrectly placing PCCDs allows access to the femoral artery, there are potentially dangerous effects to the patient including increased surface pressures and limited fracture reduction.

The COVID-19 pandemic has forced educators since 2020 to shift from all in-person learning to virtual learning through applications like Zoom. Students are now part of a collage of faces including their teachers’ who often may be dealing with technical glitches, foreign-looking interfaces, and unintentionally disruptive students. On the other side, students may struggle to find a stable working environment as they learn from home. Distance learning has been explored well before 2020, but its necessity, given the nature of a virus that preys on in-person interaction, has forced itself to the top of relevant conversation. . The issues with distance learning in primary education have roots in long standing issues with the education system as a whole. Without greater public awareness of the woes in our education system, the status quo of declining academic success, teacher salaries, and increasing classroom sizes will continue in the future. The problems with distance learning specifically represent a much more everlasting issue that is lack of accountability and action of lawmakers who are able to make these reforms.
