Interactions of mechanically induced coughing and sneezing in cat

摘要

Mutual interactions of cough and sneeze were studied in 12 spontaneously breathing pentobarbitone anesthetized cats. Reflexes were induced by mechanical stimulation of the tracheobronchial and nasal airways, respectively. The amplitude of the styloglossus muscle EMG moving average during the sneeze expulsion was 16-fold higher than that during cough (p < 0.01). Larger inspiratory efforts occurred during coughing (p < 0.01) vs. those in sneeze.
