[The critical point in laryngeal and tracheal obstruction (author's transl)]. 1980

K Schumann, and H Weerda

Laryngeal and tracheal obstruction can be more fully assessed using plethysmography. Experiences with 46 patients show that airway resistances exceeding 150 mm H2O/l/s always indicate a critical situation and these patients require urgent tracheostomy or intubation. - Three patients with glottic tumours and one patient with glottic oedema were tracheotomized because of the danger of asphyxiation. In these, resistances of between 107.4 and 150 mm H2O/l/s were found. Airway resistance exceeding 100 mm H2O/l/s are therefore critical indicators in patients with glottic oedema and laryngeal tumours.

D010243	Paralysis	A general term most often used to describe severe or complete loss of muscle strength due to motor system disease from the level of the cerebral cortex to the muscle fiber. This term may also occasionally refer to a loss of sensory function.

D010991	Plethysmography	Recording of change in the size of a part as modified by the circulation in it.	Plethysmographies
D012009	Recurrent Laryngeal Nerve	Branches of the vagus (tenth cranial) nerve. The recurrent laryngeal nerves originate more caudally than the superior laryngeal nerves and follow different paths on the right and left sides. They carry efferents to all muscles of the larynx except the cricothyroid and carry sensory and autonomic fibers to the laryngeal, pharyngeal, tracheal, and cardiac regions.

D000403	Airway Resistance	Physiologically, the opposition to flow of air caused by the forces of friction. As a part of pulmonary function testing, it is the ratio of driving pressure to the rate of air flow.	Airway Resistances,Resistance, Airway,Resistances, Airway
