Role of Impulse Oscillometry in Assessment of Pulmonary Function among Elderly

Abstract

The current study was carried out to assessthe role of IOS in assessment of pulmonary function among elderly and to provide its importance for early detection of air way disease in elderly specially who had cognitive impairment. The sample of this study consists of 100 community dwelling Egyptian elderly males and female aged 60 years and older. All elderly who participated in this study were informed with the aim of the study and agreed. While those who refused to participate in the study or had an active pulmonary disease or symptom of chronic bronchitis or with problem affecting freely mobile respiratory system were excluded from the study. Each participant was subjected to: 1- Informed oral concent 2- History taking 3- Clinical examination 4- Functional assessment by (GDS and MMSE ) 5- Pulmonary function by (spirometry and IOS)

Results of the current study showed that there are significant high agreement with significant negative linear correlations between obstruction diagnosis by IOSR5 and FEV1 were found in this study with P<0.001for each. Our study also showed linear logistic analysis was done for factors affecting FEV1 and IOSR5 Revealed that, only age and BMI significantly decrease both of FEV1 and IOSR5. So, we assume that the new computer based IOS is more reliable than conventional methods of pulmonary function assessment specially among elderly with or without cognitive impairment.
