Torrington and Henderson developed the Perioperative Respiratory Therapy (PORT) protocol for patients undergoing surgery. The preoperative evaluation includes a risk factor analysis. The authors are from St. Luke's Regional Medical Center in Boise, Idaho.
Parameters:
(1) FVC
(2) FEV1 to FVC ratio
(3) age
(4) body weight
(5) surgery location
(6) smoking
(7) cough and/or sputum production
(8) past history of significant pulmonary disease

• The range of points for surgical location is 0 to 3.
total score =
= SUM(points for all 8 parameters)
Interpretation:
• minimum score: 0
• maximum score: 12
• The higher the score the greater the surgical risk.
