Abstract

Aims and Objectives: To study the response to LTOT in patients with pulmonary hypertension due to chronic lung disease.
Materials and Methods: This retrospective study was carried out in a tertiary health care centre. Patients with COPD, Post TB OAD and ILD who were on LTOT were included in the study. Records of these patients were reviewed and was analysed.
Results: Retrospective study of 41 patients who were on LTOT was done. Out of 41 patients 18 were Post TB OAD, 12 were COPD and 11 were ILD. Average duration of LTOT/day was 16hrs and the average drop in PASP was 3.2mm Hg/yr. The average duration of LTOT/day in Post TB OAD, COPD, ILD patients were 16.2,14.8,16.8hrs and average drop in PASP in mm Hg/yr was 3.5,2.5 and 3.4 respectively.
Discussion: Response to LTOT is better seen in Post TB OAD and ILD than COPD, leading to hope of quality of life improvement.

Keywords: LTOT, PASP.
