"The team found that in general, the implantable ventilator increased the pigs' tidal volume, or the amount of air that the lungs could draw in with every breath. The most significant improvement was seen in cases where the contractions of the diaphragm and the artificial muscles were in sync. In these cases, the ventilator helped the diaphragm draw in three times the amount of air than it would without assistance.
"We were excited to see we could get such changes in the tidal volume, and we were able to rescue ventilation," Roche says.
The team is working to optimize various aspects of the system, with the goal of some day implementing it in patients with chronic diaphragm dysfunction."
