And now, I want to take you out into an invisible world, in the skies of new york city, where senior citizens are prisoners in their own homes. Stuck in high rise buildings, unable to walk down, food and medicine running out. But today, 1 million meals and 1 million gallons of water were deployed by the national guard, and I climbed the stairs with a nurse from the visiting nurse service of new york, as she made her rounds. They are out in the dark, the national guard, peoples on wheels. Thank you for coming to my door. Reporter: Carrying heavy loads up stair after stair in high rises. It's really dark. Reporter: People like nurse rosita ortiz, one of the thousands of people that work with visiting nurse service of new york, checking on patients who have little food, little water, no power. What kind of medicine for her? Short of insulin. Reporter:17 stories later, we knock on the door. Carmen and her daughter, home bound, her daughter with a walker. We want to know how you're doing. I am doing fine. Reporter: Really? I was scared to death. Reporter: They tell us, this is their only water. That's all you have left? It's almost gone. Reporter: They've run out of batteries. They used candles last night. Last night, it was dark. It was dark. And I was going like this, touching the walls to get to the bathroom. I was this close, I couldn't find the bathroom. Reporter: Rosita checks carmen's blood pressure, takes her temperature, makes sure she's all right. And carmen shows me the carmen she used to be. As we head back downstairs, an endless stream of need. A 70-year-old woman trying to carry up heavy jugs of water. A 53-year-old woman who has to read lips, who tells me she has breathing problems, her chest hurts. Will you come down and go to see a doctor? Yeah. Reporter: Okay. Come with us. We take her to the emergency room. Take care of you. Thank you. Reporter: And they are taking care of her and we will check back on the people you just saw, and, by the way, we are getting water and batteries to carmen and her daughter for tonight. And, we mentioned the 4,300 members of the national guard working tonight in the storm zone. We stopped by the 69th ridegiment armory today and we thought you'd like to know, they are able to deploy because of generators supplied by angels -- victoria's secret. They had backup power on hand for a flashy fashion show next week and gave it to the national guard. Way to go, victoria's secret.
