The Transplant team said swimming and biking would be a great way for him to keep his strength up before surgery. however, Garran has liquid O2 now and also has a PICC line. Since he has been out of the hospital for a few days he has wanted to go swimming soooo bad, but I have yet to figure out how to go swimming with the O2 on. He cant take it off for any length of time like he used to before this last admission, or he desatts very quickly. He drops down in the 60's - 70's in minutes. So We figured out how to cover the PICC for baths and swimming etc, but the O2 is a mystery, anyone have any ideas?
