In terms of posture for bronchial asthma, normally, during remission, it does not have any impact, and one can sleep or lie down in any desired position. However, during an asthma attack, especially a severe one, patients often adopt a forced semi-sitting or upright sitting position to alleviate respiratory distress. This posture indicates that the patient is experiencing severe respiratory difficulties, whether it is bronchial asthma or other conditions like chronic obstructive pulmonary disease or severe heart failure, patients will adopt this posture.
