thanks for writing to us.
i understand your concern for your mother.
There are a number of therapies which can be tried in such a situation but mind it they are not a substitute of an examination by a clinician in ER and therapy given as guided by examination of patient. i would like you to consult your physician who is looking after her about these therapies before trying it at home. She can be given plain steam/ inhalational mucolytic
like acetyl cysteine/ inhalational fast acting bronchodilators through nebulizer
. i am not telling you the exact drug names as i sincerely wish you to consult her physician before trying them.
hope you understand my intent.
