In an adult, the relationship between the MUF blood flow and the patient’s total cardiac output may be 1/20, rather than 1/5. So the oncotic pressure increase of the pulmonary artery blood is much less than during infant MUF. Therefore there is less oncotic pressure to remove fluid from the lungs. As a result, there are negligible pulmonary benefits. Typically the increases in clotting factors and hematocrit are also small. Therefore the benefits of MUF in adults may not be worth the time required to perform the procedure.
Perfusion Theory is an educational platform for the Oxygen Pressure Field Theory (OPFT). August Krogh’s theoretical concept of the oxygen pressure field is explained and then applied to clinical applications in perfusion practice.
