USP cria 'capacete respirador' para tratar paciente com covid-19

Capacete filtra o ar do paciente diminuindo risco de contaminação Divulgação/USP

Na busca por alternativas viáveis no combate ao novo coronavírus, pesquisadores da USP, em parceria com a iniciativa privada, estão desenvolvendo um capacete respirador de baixo custo para fazer a respiração mecânica em pacientes com covid-19.

O projeto está em fase final de desenvolvimento e deve ficar pronto até o fim de maio. Os pesquisadores envolvidos no projeto apelidaram o equipamento de “escafandro”, pela forma arredondada da cúpula de acrílico, parecida com a utilizada por mergulhadores no século 19.

Benefícios do dispositivo

“Trata-se de uma opção menos invasiva, já que em muitos casos pode ser uma alternativa para evitar a necessidade de utilização do tubo endotraqueal introduzido no paciente”, conta o professor Raul Gonzales Lima, coordenador da iniciativa em entrevista à Revista USP

Além disso, o “escafandro” possui dois tubos para fazer a circulação do ar. Assim, o equipamento controla a pressão e a concentração do oxigênio e faz a respiração do paciente.

De acordo com o professor Raul, o sistema impede que o paciente respire no mesmo ambiente que funcionários de saúde e outros pacientes que podem estar próximos, pois filtra o ar que sai do dispositivo. Essa é uma maneira de garantir um ambiente mais seguro e com menor risco de contaminação.

Produção rápida

Segundo pesquisadores, já existem trâmites junto a Anvisa para a regulação do aparelho. A iniciativa faz parte o Projeto Inspire - Ventilador pulmonar de baixo custo, que funciona na Poli, dentro da USP mas conta com assistência das faculdades de Medicina e odontologia, também da Universidade de São Paulo.

Segundo a USP, após a aprovação do projeto, sua produção poderá ser rápida e em larga escala, pois utilizará materiais e fábricas nacionais.

Duke Kahanamoku reflects on surfing, Olympics, and old Hawaii in 1966 interview

Duke Kahanamoku is the most influential surfer of all time and is often hailed as the father of modern surfing. There is nearly no one questioning these titles. Recently, Public Broadcasting Service (PBS) Hawaii unveiled a never-before-seen interview with the legendary surfer and Olympic swimmer. In the 1966 episode of Pau Hana Years, a seminal Hawaii television program that aired on KHET-TV (now PBS Hawaii) for 16 years, running from 1966 until 1982, Bob Barker chats with Duke Kahanamoku, then 76. The conversation drifts from royal ancestry to Olympic lanes, from Hollywood sets to a surfboard shaped by hand, tracing the outline of a life that helped define modern surfing and Hawaii's public image in the 20th century. And if you know little about the man who dreamed of getting surfing into the Olympic Games, this is a precious piece of history. A name with history, worn casually The interview starts with Kahanamoku explaining that "Duke" is not a title but his giv...

The hydrodynamics of surfboard fins

Have you ever wondered why a surfboard fin looks like that? It is a single or a set of fixed blades or keels located under a board, near the tail, often no bigger than a hand. Yet that small surface is where much of the surfboard's behavior takes place. Speed, hold, looseness, and the feeling of control all trace back to how water moves around fins. The physics of surfboard fins falls under hydrodynamics, the study of how fluids behave in motion. So, according to science, they feature a shape designed to turn flowing water into several forces. Let's take a look at what's at stake when fins and water interact. Lift and the feeling of control One of the key variables in hydrodynamic terms involving surfboard fins is lift. When a surfer leans into a turn, the board tilts and the fins meet the water at an angle. The angle is enough to create a pressure difference between the two sides of the fin. Water speeds up on one side and slows on the other. The result is a sidewa...

How paddleboarding transforms your body and mind

Adventure is on our doorstep. With so many different bodies of water available to paddleboarders, from city canals to coastal routes, we can find adventure in places much closer to home than people might initially expect. According to the Canal and River Trust, 50 percent of people in England and Wales live within just eight kilometers of a canal or river, and eight million people live less than one kilometer away. I had lived within just a few kilometers of the Leeds and Liverpool Canal for years and never really explored it before stand-up paddleboarding (SUP) came into my life . The challenge created both a new perspective and a deeper love for where I lived and the areas which I passed through. On my coast-to-coast journey, I slept in my own bed for two nights as the route passed through my then hometown of Skipton, yet I felt I was on a grand journey of discovery. We are braver, stronger, and more resilient than we think. SUP not only helps us feel more connected to our va...
