Temperature Measurements in the Respiratory Tract of Laryngectomized Patients

Abstract

Two phenomena are described which can be observed in laryngectomized patients with simultaneous and continuous recording of nasal temperature and respiratory rate:

1. There is an air-flow through the nose of the laryngectomized patient synchronous with respiration and heart-beat which may account for the function of smell of these individuals.

2. On insufflation of the nose with different amounts of air at different temperatures the respiration reacts with a lower rate, other types of reaction being inconstant. This reflex is in close relation to others described by Kratschmer and Sercer.
