Overview
Repeated measurements of different clinical and physiological parameters are believed to be useful in assessing the clinical course of IPF. Assessment of dyspnea, using an established clinical scale for rating the impact of dyspnea on activities. [1] Lung volumes, DLCO, resting arterial blood gases, cardiopulmonary exercise testing with measurement of gas exchange, HRCT lung scans are our current tools for diagnosing idiopathic interstitial pneumonia. Physiologic testings have been used to determine the current functional lung capacity. Studies have shown that conventional lung function tests by spirometry have more precision in prognosis of patients with IPF, while extensive tests like gas exchange measurements at rest and exercise do not add additional information to make the prognostic or treatment evaluation more precise. [2].
