The correlations between pulmonary function tests and polysomnographic parameters in overlap syndrome

Aim: This study aims to reveal the relationship between Pulmonary Function Tests (PFTs) parameters and polysomnographic parameters. It determine guiding values in treatment selection, with hypothesis that easily accessible PFTs can be useful clinical evaluation for patients restrictive or obstructive type disorders.
 Material Method: One hundred forty-six and/or pulmonary dysfunction who underwent polysomnography sleep clinic of our hospital June 2019 December were included study. Polysomnography (PSG) results obtained. Age, gender, body mass index (BMI), Epworth Sleepiness Scale (ESS) score, parameters, apnea-hypopnea (AHI), nocturnal oxygen saturation, tolerable positive airway therapy modality, pressures recorded.
 Results: Of 146 34.9% women most (92.5%) had an disorder PFTs. disorder, 71 being followed up a diagnosis chronic disease (COPD) 64 asthma. Interstitial lung was observed 5 out 11 cases (7.5%) obesity resulted remaining 6 cases. Simple snoring 5.5%. Mild OSAS at rate 30.1%. Moderate-severe detected 64.4% patients. When optimal inspiratory/ expiratory pressure (IPAP/EPAP) determined by automatic bilevel (ABPAP) titration analyzed, moderate negative correlation IPAP value forced vital capacity (FVC) (L) (r=-0.432, p=0035)
 Discussion: The this show used predict findings obstructive/restrictive disorders. Almost two-thirds apnea (OSA)-related symptoms group have moderate-severe syndrome (OSAS). Based on ROC analysis, we believe it would appropriate recommend devices, especially volume one second (FEV1)
