The day after Wilma Banks lost power, the stale summer air inside her New Orleans apartment became suffocating.
Typically when her breathing gets strained, Banks straps on her plastic nebulizer mask. After turning it on, a medicated mist flows into her lungs, making her short breaths full again.
But after Hurricane Ida knocked out her power on Aug. 29, she couldn't use the nebulizer. She knew her oxygen level would continue to drop. Her heart could stop.
