Hi,
Thank you for posting your query.
Your husband's symptoms are suggestive of a condition called as
cough syncope. In this condition, during severe bouts of coughing, the venous return to the heart decreases, which results in reduce cardiac output. As a result, the brain gets less blood and the person faints. After a while, the blood supply to the brain is restored and the person comes around.
It is not a serious condition and no treatment is usually required.
I hope it helps. Please get back if you require any additional information.
Wishing you good health,
