Before planned surgical treatment of @entity2 , the @entity1 's respiratory system function should be evaluated. According to the current guidelines, the assessment should start with measurements of FEV1 (forced expiratory volume in 1 second) and DLco ( @entity1223 lung diffusion capacity). Pneumonectomy is possible when FEV1 and DLco are > 80% of the predicted value (p.v.). If either of these parameters is < 80%, an exercise test with @entity4962 max ( @entity26 consumption during maximal exercise) measurement should be performed. When @entity4962 max is < 35 % p.v. or < 10 ml/kg/min, resection is associated with high risk. If @entity4962 max is in the range of 35-75% p.v. or 10-20 ml/kg/min, the postoperative values of FEV1 and DLco (ppoFEV1, ppoDLco) should be determined. The exercise test with @entity4962 max measurement may be replaced with other tests such as the shuttle walk test and the stair climbing test. The distance covered during the shuttle walk test should be > 400 m. @entity1 considered for lobectomy should be able to climb 3 flights of stairs (12 m) and for pneumonectomy 5 flights of stairs (22 m).
