At SSM Health St. Anthony Hospital in Oklahoma City, 18 covid-19 patients lacked beds Tuesday and were being treated on mattresses on the floor of the ICU, with more than half of them on ventilators, reported KFOR-TV. Amy Petitt, an ICU charge nurse at the hospital, fought through tears during a tour of a hospital pushed to its limits by the highly transmissible delta variant. Ninety percent of the 79 covid patients in St. Anthony’s ICU are unvaccinated, Tammy Powell, president of the hospital, told The Washington Post.
