“…The Medikro Pro (Medikro Oy, Kuopio, Finland) portable spirometry device was used for bedside pulmonary function testing in all patients. The device is connectable to a portable computer, and the software includes reference values for pulmonary functions of the Finnish general population (29). Pre-operative pulmonary functions were defined as normal, mildly decreased, moderately decreased or severely decreased in accordance to these reference values (Table 1).…”

Two respiratory physiotherapy modalities were compared in a randomized controlled trial on patients undergoing minor pleuro-pulmonary surgery. Methods:Forty-five patients were randomly allocated into positive expiratory pressure (PEP) therapy (n=23) and inspiratory muscle training (IMT) groups (n=22). Individualized group specific physiotherapeutic guidance was administered preoperatively, and once a day postoperatively. Patients also performed independent exercises and kept a logbook. Pain was assessed on a numerical reference scale (NRS).Volumetric pulmonary function values and walking distance were recorded preoperatively, and on first (POD1) and second postoperative days (POD2). Pre-and postoperative values were compared using two-way repeated measures analysis of variance. Results:Patient characteristics and pleuro-pulmonary interventions were similar between the groups.Thoracotomy was performed in 14/45 and video assisted surgery (VATS) in 31/45 of cases. Preoperative volumetric pulmonary functions were normal or slightly decreased in 29/45, and fell significantly (P<0.001) on the first postoperative day (POD1) and improved but remained significantly lower on the second postoperative day. The recovery of mean FEV1, FIV1 and FIVC values was greater in the IMT than in the PEP group between POD1 and POD2, but without significant difference. The corresponding relative to preoperative values were higher in the IMT group, with a significant difference in FEV1 (P=0.045). Also relative PEF and FIV1 values seemed to be slightly higher in the IMT compared to the PEP group, but not significantly. Average NRS values for pain were lower in the IMT group (P=0.010) but only on POD1. Air leak was noted in 4/45 patients, two in each group, on POD1, and two in PEP groups and one in IMT group on POD2. Mean measured walking distances between groups did not differ. Mean hospital stay was 4 days in the PEP group and 3 days in the IMT group. There was no hospital mortality. Conclusions: Pulmonary function values decreased significantly after minor lung resections, supporting rehabilitative respiratory physiotherapy to avoid postoperative pulmonary complications (PPCs). Both PEP and IMT training were well tolerated and equally efficient when comparing spirometry values at three time points. IMT appeared advantageous regarding relative FEV1 recovery and immediate postoperative pain.

Measurement standards for pulmonary diffusing capacity were updated in 2005 by the ATS/ERS Task Force. However, in Finland reference values published in 1982 by Viljanen et al. have been used to date. The main aim of this study was to produce updated reference models for single-breath diffusing capacity for carbon monoxide for Finnish adults. Single-breath diffusing capacity for carbon monoxide was measured in 631 healthy non-smoking volunteers (41.5% male). Reference values for diffusing capacity (DLCO), alveolar volume (VA), diffusing capacity per unit of lung volume (DLCO/VA), and lung volumes were calculated using a linear regression model. Previously used Finnish reference values were found to produce too low predicted values, with mean predicted DLCO 111.0 and 104.4%, and DLCO/VA of 103.5 and 102.7% in males and females, respectively. With the European Coalition for Steel and Coal (ECSC) reference values there was a significant sex difference in DLCO/VA with mean predicted 105.4% in males and 92.8% in females (p < .001). New reference values for DLCO, DLCO/VA, VA, vital capacity (VC), inspiratory vital capacity (IVC), and inspiratory capacity (IC) are suggested for clinical use to replace technically outdated reference values for clinical applications.
