A bulge although it is increased in size after cough impulse

when patient removes his hand we see a bulge although it is increased in size after cough impulse…but before cough impulse there is small bulge present…so how can it justify reducibility(which means bulge to come out "only"when force is applied).

A reducible hernia is one which can be flattened out with changes in position (e.g. lying supine) or the application of pressure. The hernia may re-appear if the patient stands up, coughs or the application of pressure is removed.

Thank you.
