Tl:dr version ... Yes, because we don't build iron lungs anymore. "Instead, they would likely use mouth intermittent positive pressure ventilation."
Ventilators are positive pressure, pushing air into the lungs which is good for those with breathing issues.
Irons lungs are negative pressure because polio patients don't have a problem with their lungs ... polio has invaded their brain and spinal cord and killed control over their chest muscles and diaphram. Negative pressure forces their chest to rise and fall, making them "breathe".
The article is worth reading.
