Thousands of Texans depend on dialysis treatments. Extended power outages put their lives at risk.

Michelle Adams-Walton, 58, was five minutes into her dialysis treatment in Leander, the needle in her arm circulating blood through a machine to filter it since her kidneys cannot — when the power went out. Nurses rushed to unhook patients from machines to prevent life-threatening blood clotting. She returned home, where the power was also going in and out, without treatment.
