Reciprocal changes in nasal resistance to airflow caused by pressure applied to the axilla.
The resistance to airflow of each nasal passage was measured using active, posterior, rhinomanometry. Application of pressure to the axilla for 15 min by means of a wooden crutch caused a reciprocal change in nasal resistance with an ipsilateral increase and a contralateral decrease in resistance. The results are discussed in terms of reflex changes in sympathetic tone to the nasal venous erectile tissue.
