Is night-time asthma really obstructive sleep apnoea?

Patients reporting nocturnal asthma-like symptoms may really have obstructive sleep apnoea, Australian research suggests.
The findings have led the authors to call for those who have woken at least once in the past 12 months with a feeling of tightness in the chest, shortness of breath or asthma together with clinical features of obstructive sleep apnoea (OSA) to be screened for the disease.
