Hospitals in Lisbon flooded with COVID-19 patients are at risk of failing to meet soaring demand for oxygen, the head of Portugal’s doctors association said as Germany sent military medics to the country to evaluate how they can help. Portugal, with a new record of 293 dead on Wednesday, is struggling to handle a record surge in infections. This comes as Reuters revealed more than 20 ambulances with COVID-19 patients queued outside the Santa Maria Hospital in Lisbon on Wednesday evening as they waited for beds to become available.
