MISSION, Kan. (AP) — The COVID-19 surge is stretching oxygen supplies tight and sending hospitals scrambling for more ventilators, even as there are glimmers of hope in some hotspots.

In Tulsa, Oklahoma, a hospital recently called 911 after coming within just a few hours of running out of oxygen because they needed an emergency transfer for a patient on high-flow oxygen.

But there are signs of optimism in some parts of the country. Cases and hospitalizations are dropping in some of the worst-off states.
