Didyouknow the earl

#Didyouknow the earliest breathing machine was called the Drinker respirator. It was invented in 1928 and was known as an 'iron lung'. These machines were used between the 1930s and 1950s by patients whose breathing muscles had been paralysed by polio. #FIMEShow #FIME2020 #FIME #didyouknowWednesday #FIMEDidYouKnowWednesday #ventilator #medicaldevices #Americanhealthcare #UShealthcare
