You can hear the frustration in the nurse's voice as he narrates the video, walking closer to an open window.
"You have to be an engineer to make this work," he says. "You have to be like MacGyver."
The video moves past a woman on oxygen, the tube running down from her nose to the gurney she's sitting on and, eventually, out that open window.
It runs to another window, the green tube swinging in the breeze above an open courtyard a half-dozen stories below. The tube ends at an oxygen hookup in the wall of the other room.
This is the only way that woman, a Covid-19 patient at this hospital in the Brazilian capital of Brasilia, can get oxygen. The room where the oxygen source is located is so overwhelmed with Covid-19 patients, she has to sit in what is otherwise a hallway, her life-saving oxygen precariously fed to her.
The scene is a microcosm of what is playing out across Brazil right now amid a brutal and out-of-control wave of Covid-19.
On Thursday night, Brazil's Health Ministry reported the gruesome figure of more than 100,000 new Covid-19 cases confirmed in a single day, the country's highest such figure since the pandemic began.
So far, a total of 303,462 people have died in the country from the virus, according to official data.
But it's the seven-day averages that paint an even bleaker picture.
Signs of collapse
First responders, hospital personnel and even cemetery employees have told CNN they've been brought to their knees by this latest wave.
"It's a war scenario," said paramedic Luis Eduardo Pimentel in São Paulo. "I can barely describe what I'm seeing, it is so sad what is happening to the country."
He described non-stop Covid-19 calls, unnecessary deaths, and hospitals so overburdened, they take supplies from wherever they can.
CNN spoke to him after his shift ended, earlier than expected, after a hospital took the gurney he had brought his Covid-19 patient in on -- the hospital had run out of beds.
Other examples are myriad.
