"It first struck me how different it was when I saw my first coronavirus patient go bad. I was like, Holy sh*t, this is not the flu. Watching this relatively young guy, gasping for air, pink frothy secretions coming out of his tube and out of his mouth. The ventilator should have been doing the work of breathing but he was still gasping for air, moving his mouth, moving his body, struggling. We had to restrain him.
With all the coronavirus patients, we've had to restrain them. They really hyperventilate, really struggle to breathe. When you're in that mindstate of struggling to breathe and delirious with fever, you don't know when someone is trying to help you, so you'll try to rip the breathing tube out because you feel it is choking you, but you are drowning.
I spoke to a respiratory therapist in New Orleans, whose job is to ensure that patients are breathing well. He works in a medium-sized city hospital's intensive care unit. (We are withholding his name and employer, as he fears retaliation.) Before the virus came to New Orleans, his days were pretty relaxed, nebulizing patients with asthma, adjusting oxygen tubes that run through the nose or, in the most severe cases, setting up and managing ventilators. His patients were usually older, with chronic health conditions and bad lungs.
Since last week, he's been running ventilators for the sickest COVID-19 patients. Many are relatively young, in their 40s and 50s, and have minimal, if any, preexisting conditions in their charts. He is overwhelmed, stunned by the manifestation of the infection, both its speed and intensity. The ICU where he works has essentially become a coronavirus unit. He estimates that his hospital has admitted dozens of confirmed or presumptive coronavirus patients. About a third have ended up on ventilators.
He spoke to me by phone on Thursday about why, exactly, he has been so alarmed.
"Reading about it in the news, I knew it was going to be bad, but we deal with the flu every year so I was thinking: Well, it's probably not that much worse than the flu. But seeing patients with COVID-19 completely changed my perspective, and it's a lot more frightening."
We go and check vitals on patients every four hours, and some are on a continuous cardiac monitor, so we see that their heart rate has a sudden increase or decrease, or someone goes in and sees that the patient is struggling to breathe or is unresponsive. That seems to be what happens to a lot of these patients: They suddenly become unresponsive or go into respiratory failure.
It's called acute respiratory distress syndrome, ARDS. That means the lungs are filled with fluid. And it's notable for the way the X-ray looks: The entire lung is basically whited out from fluid. Patients with ARDS are extremely difficult to oxygenate. It has a really high mortality rate, about 40%. The way to manage it is to put a patient on a ventilator. The additional pressure helps the oxygen go into the bloodstream.
"Normally, ARDS is something that happens over time as the lungs get more and more inflamed. But with this virus, it seems like it happens overnight. When you're healthy, your lung is made up of little balloons. Like a tree is made out of a bunch of little leaves, the lung is made of little air sacs that are called the alveoli. When you breathe in, all of those little air sacs inflate, and they have capillaries in the walls, little blood vessels. The oxygen gets from the air in the lung into the blood so it can be carried around the body.
"Typically with ARDS, the lungs become inflamed. It's like inflammation anywhere: If you have a burn on your arm, the skin around it turns red from additional blood flow. The body is sending it additional nutrients to heal. The problem is, when that happens in your lungs, fluid and extra blood starts going to the lungs. Viruses can injure cells in the walls of the alveoli, so the fluid leaks into the alveoli. A telltale sign of ARDS in an X-ray is what's called 'ground glass opacity,' like an old-fashioned ground glass privacy window in a shower. And lungs look that way because fluid is white on an X-ray, so the lung looks like white ground glass, or sometimes pure white, because the lung is filled with so much fluid, displacing where the air would normally be."
Even if you do survive, it can do long term damage.
