Word that some icy use air near capacity as the number of cases sores, and tonight the doctors who say they do not have what they need.

Here's NBC's chief national correspondent, Matt Government Tonight, one of the biggest expansions in hospital space in American history from coast to coast.

Temporary hospitals being built at breakneck speed.

This field unit for Corona virus patients under construction on a soccer field outside Seattle.

And this has emergency room officials fear being overrun when the virus peaks.

We have patients who we suspect that we have Kobe but have not been.

The testing is not completed because the testing is taking so substantially.

Long are I see youse are already at capacity before this pandemic began, and now we're pushing them over.

While thousands are lining up a drive through testing sites like these in Texas and Georgia, so many seeking tests are unable to get them.

I was sitting on the couch and my wife was in the kitchen, and I almost passed out just out of the blue, 39 year old Sacramento resident Justin Will Light has been to the emergency room twice in the last eight days.

Doctors tell him they are 100% certain he has the virus, but they told him the tests are on Lee.

For those in dire need, it was more frustrating for my wife because my wife wanted more definitive answers with officials in Los Angeles setting up this RV park as a possible quarantine site.

Doctors across the country now pleading with people to stay home, this physician in Atlanta holding up a sign saying, I stayed at work for you.

You stay home for us, especially since some of those doctors on the front lines are especially vulnerable to I can't walk away from this pandemic while I needed.

But that said, I have at least a 10 fold higher mortality rate.

Some hospitals reporting a short supply of ventilators, doctors and other countries have rigged them so patients could share them but haven't taken that measure yet that is now being discussed as a last resort among some health officials were exploring how to make that work and that creativity is absolutely essential.

Yeah, we need creativity, but we also need them to be extraordinarily careful, and I know they're considering everything sharing those ventilators a worst case scenario because there are risks with that, too.

There are David, and that's because it's never before been tried on humans.

Now they can split those ventilators, but it still requires skilled technicians to monitor the patient's.

There's also a concern that these patients are breathing the same air and could transmit diseases.

And this is why doctors keep telling us, toe flatten the curve so hospitals don't have to get into these situations where they used these unprecedented measures.
