INTEGRATED PULMONARY INDEX AS A POSSIBLE SCREENING TOOL FOR PULMONARY DISEASE

Introduction: The Integrated Pulmonary Index is a new score which integrates measured end tidal CO2 (etCO2), heart rate (HR), pulse oxygen saturation (SpO2%), and respiratory rate (RR) into one integer value (FDA cleared algorithm developed by Oridion Capnography, Inc) in a scale of 1 though 10 with normal being a high value (8-10). Spirometry is a screening tool for respiratory health where exhaled volume and flow are measures and IPI is a cardiopulmonary status indicator. We hypothesized that the at rest IPI could be a predictor of lung function for those patients referred for a routine spirometry pulmonary function test. Methods: Pulmonary function tests with documented values for at rest IPI, FEV1/FVC, FEV1% predicted (FEV1%), and gender were included in the data analysis. Results: Sixty-five patients (34 males and 31 females) met the criteria for data analysis. The IPI Normal Group (IPI 8-10, n=57) had a mean FEV1/FVC of .70, mean FEV1% of 72, and a mean IPI of 10. The low IPI Group (IPI < 8, n=8) had a mean FEV1/FVC of .48, mean FEV1% of 45, and a mean IPI of 6. Discussion: The IPI scale suggests interventions by health professionals may be considered beyond current treatment at an IPI of 6 or less. In this retrospective study, some patients had prior diagnosis and were already receiving effective treatment, as indicated by a higher IPI score. For example, one patient with poor spirometry was noted to be on O2 therapy while the IPI was recorded and had a normalized IPI – an indication that oxygenation was effective. Conclusion: In this study the IPI identified patients with poor lung function, possibly in need of intervention. The study also revealed that patients on bronchodilator and oxygen therapy were responding positively to the therapy. A prospective controlled study is needed to evaluate more precisely IPI as a potential screening tool and method to monitor response to therapy for pulmonary patients. The IPI may have a role to screen for unrecognized pulmonary disorders and also as a tool to monitor outcomes of pulmonary care. Sponsored Research - None
