Liam's lung isn't opening any more and his chest x-ray from yesterday to today was unchanged. It's open, but not by much. So, they've started IPV treatments every 4 hours and watching him do that ranks right up there with watching him be on a ventilator. IPV stands for Intrapulmonary Percussive Ventilator and it basically forces little bursts of air (mixed with saline and albuterol) into his lungs to try to break loose the mucous and open up his airways. The other treatment they were talking about doing is IPPV - Intermittent Positive Pressure Ventilation and I'm not sure what that entails...not sure I wanna know given how hard the IPV is to watch...he is so strong I could barely hold him when they started the treatment because he was throwing such a fit. I felt terrible...anyway, here's hoping tomorrow's x-ray shows some improvement! They're also trying to figure out why he's had diarrhea for almost 2 weeks so they've sent off some stool samples - the Rotavirus one came back negative but the others won't be back til tomorrow.
