Abstract

Purpose: We presented a study of the importance of integrated pulmonary index (IPI) correlated with arterial blood gas analysis in the respiratory management of the patient (surgical or internal medicine) recovering in intensive care unit. Methods: The IPI incorporated four real-time respiratory measurements; oxygen saturation (SpO2), the level of carbon dioxide at the end of expiration (ETCO2), respiratory rate (RR), pulse rate (PR). We measured continuosly IPI with repeated arterial blood gas analysis and clinical observations in 100 patients from May/2015 to August/2015 recovered in our intensive care unit. Correlation between measurements was analysed statistically. We analyzed data with SPSS program. Results: We observed 47 patients in mechanical ventilation support (orotracheal intubation), 8 patients in non invasive ventilation support (NIMV) and 45 patients with venturi mask ventilation. There found to be a correlation between IPI (7.68 ± 1.92) and SpO2 (96.85 ± 3.58), RR (18.96 ± 7.18). Correlations were identified between SpO2 of IPI monitor and arterial blood gas Sat measurements, and between EtCO2 (34,27,66) value and arterial blood gas PaCO2 (38.04 ± 8.07) measurements. Conclusions: IPI correlates arterial blood gas values and provides a single numerical value for early identification of respiratory failure in intensive care. IPI ensures ease of use by displaying multiple parameters on a single screen and being a bed-side, non-invasive method. Even, it might be a potential candidate to be a more dynamic measurement than arterial blood gas.
