SINGAPORE - A hospital has come up with new box shields that offer added protection for healthcare workers performing high-risk aerosol-generating procedures on critically ill patients, including Covid-19 cases.
When performing aerosol-generating procedures on ICU patients, healthcare workers have to don a powered air-purifying respirator , a battery-powered air purifying mask, which can take three to five minutes to put on. "Unlike many of the currently seen box shields, we have designed a bigger and custom-made isolation chamber to easily retrofit our ICU and transfer beds," said Dr Tan Chee Keat, head and senior consultant of intensive care medicine, who led the project.
The box shields are of different sizes and are used in different settings - one for ICU beds, one for patient transfer and one for intubation. The intubation BCU is similar to the treatment BCU, but smaller, at 50cm by 68cm at its base, and 60cm high.The team believes that the detachable and purpose-built qualities of the box shields make them a first-of-their-kind.
