| Popis: | The finding of an arterial oxygen tension (PaO,) of less than 7.3 kPa defines those patients in whom long-term oxygen therapy (LTOT) is likely to be of benefit (1). Where oxygen tensions are higher than this level, oxygen administered on an ‘as required basis may still be useful to alleviate exercise-induced hypoxia (2). Patients who may benefit from ‘as required’ oxygen can be identified by performing’an exercise test to detect falls in oxygen (3). Exercise- induced oxygen desaturation (ED) may correlate with nocturnal oxygen desaturation (ND) in patients with chronic obstructive pulmonary disease (COPD) because both may result from increasing severity of disease (4). The aim of this investigation was to define two groups of patients according to the presence or absence of ED, and to compare the incidence and severity of ND. |
