Abstract

Systematic study in animals indicated, that in addition to cough there are 2 distinct airway reflexes. The aspiration reflex (AspR) characterized by rapid and strong gasp-like inspiration provoked by stimulation of nasopharynx, nasal phyltrum or auricle of ear. The expiration reflex (ExpR) manifests by prompt expiration, induced by laryngeal stimulation. Both reflexes strongly activate the brainstem inspiratory or expiratory generators, respectively, and inhibit the opposite respiratory and various functional disorders. This paper indicates several functional disorders occurring during manipulation with airways in anaesthesiological practice, which can be influenced positively or negatively by application of these special reflexes (asphyxia, breath-holding, laryngospasm, bronchospasm, sleep apnoea episodes, arrhythmia, collapse, etc.). The AspR, ExpR and CR (cough reflex) have important clinical relevance in anaesthesia and emergency medicine applicable also in domestic therapy and in hardly accessible places particularly by application of ICT (Information & Communication Technologies) using a mobile connection of the patient with the remote hospital centre.
