Lung diffusing capacities for nitric oxide and carbon monoxide at rest and post-walking in long COVID.

ABSTRACT:

Background

Approximately one-third of long coronavirus disease 2019 (long COVID) patients report breathlessness and fatigue even during activities of daily living. We hypothesised that abnormalities of combined diffusing capacity of the lung for nitric oxide (D _LNO) and carbon monoxide (D _LCO) at rest or after mild exercise are associated with breathlessness in patients with long COVID.

Methods

Single-breath combined D _LNO and D _LCO were measured at rest and immediately after a short bout of treadmill exercise simulating ordinary walking in 32 Caucasian patients with long COVID and dyspnoea at rest. 20 subjects served as a control group.

Results

At rest, combined D _LNO, D
