129 4.1.2.4 Interventions. All the patients underwent a full course of pulmonary rehabilitation prior to randomization (NET) or surgery (Non-NETT). This rehabilitation was done under the same protocol, and was as follows. Six-week program of intensive outpatient rehabilitation - Program 3-5 times a week at hospital program - Supervised portion of exercise to be done with the following: Two-hour sessions - Cross training - 30 min. continuous treadmill exercise at modified Borg level 7.5 - 15 min. on arm ergometer at modified Borg level 7.5 - 15 min. on stair stepper/bicycle ergometer at modified Borg level 7.5 or with Karvonen's target heart rate intensity factor 0.6 - Pulse oximetry (Supplemental 02 as needed to maintain Sp02 > 90 %) - Telemetry - Blood pressure monitoring - Patient education sessions with 6 basic topics - Basic breathing techniques - Anatomy/Physiology - Medications - Stress and relaxation - Nutrition - Armchair aerobics - Patient specific training in breathing and relaxation techniques
130 The patients who underwent LVRS were given their surgery within a month after the completion of the initial rehabilitation program. The surgery was to be done as per the surgeon and/or the NETT protocol. This testing and analysis had no bearing on the surgical plans for the patients. After surgery, the patients were given treatment and physical rehabilitation as needed to insure that they could be remobilized. Both the surgical and medical patients then received a second six-week course of rehabilitation. The subjects were then followed at 3-month intervals for a year and then for 4 years at 6-month intervals, out to 60 months (5 years). It should be noted that the whole time the patient participated in the study, qualified personnel with appropriate emergency equipment and emergency facilities were readily available to treat any problems that may occur.
