Orthopneic breathing is specifically characterized by difficulty or painful breathing except when the person is sitting upright or standing. This condition often arises due to various health issues, such as heart or lung diseases, where gravity helps expand the lungs when in an upright position, thus alleviating discomfort.

The other choices do not accurately depict orthopneic breathing. Difficulty breathing while lying down may describe a related situation but does not encompass the full range of orthopnea, which is more about the positioning. Normal breathing patterns are not associated with orthopnea since this condition implies some level of respiratory distress. Painful breathing in any position does not reflect the characteristic relief that comes from being seated or standing, which is a key aspect of orthopneic breathing.
