The purpose of this research study is to compare two methods of recovering blood from surgical sponges used during heart and lung surgeries. The two methods are: 1) manually wringing sponges by hand, and 2) automated wringing sponges by an FDA approved suction device. Both methods are already in use in heart and lung surgeries at University Hospitals at the discretion of the surgeon.

Inclusion Criteria:

• Undergoing heart or lung transplant, redo sternotomy, aortic surgery, and/or multi-valve repairs/replacements; and
• At University Hospitals Cleveland Medical Center.

Exclusion Criteria:

• Patients with known bleeding disorders, including disseminated intravascular coagulation (DIC), prothrombin deficiency, factor V deficiency, factor VII deficiency, factor X deficiency, factor XI deficiency (hemophilia C), Glanzmann disease, hemophilia A, hemophilia B, idiopathic thrombocytopenic purpura (ITP), and Von Willebrand disease (types I, II, and III);
• Patients undergoing emergent or emergent salvage surgery; and
• Patients actively participating in another clinical trial which could affect outcomes.

Subjects will be blinded to the order of intervention.
