We suggest that it is because articulation at the larynx is ambiguous between reflecting a place of articulation in the vocal tract or reflecting a state of the glottis.
7) During avian intubation, the glottis should be visualized, and the head should be extended and aligned with the neck to maintain a straight trachea and central placement of the distal end of the tube into the tracheal lumen.
The posterior glottic tissue no longer prolapsed into the glottis, but there was continued mucosal thickening and inflammation.
The placement of a pharyngeal pack prevents liquids and solid debris from entering the glottis, moving down to the tube cuff or further down the trachea in a spontaneously breathing child with an uncuffed tube that is too small.
5) OSA is characterized by repetitive forced inspirations against a closed glottis (Muller maneuver) that are likely to cause major decreases in lung interstitial pressures, (6) resulting in alveolar deformation (7) and proinflammatory capillary responses, (8) including stress failure.
The glottis is at the level of the thyroid cartilage.
The "closed quotient" refers to the duration of the phase of the vibratory cycle in which the vocal folds close the glottis.
Midwives and obstetricians in Iran encourage women to employ the 'Valsalva' maneuver at the beginning of the second stage of labor(once the cervix has been confirmed as fully dilate), regardless of whether they have any urge to bear down which requires repeated, prolonged breath holding and bearing down which causes the glottis to close and increases intrathoracic pressure [1].
The patient was intubated in the theatre and direct laryngoscopy demonstrated an oedematous supraglottis with redundant patchy necrosis occluding the glottis.
It has been found by this laboratory, that maintaining the breath hold with no valve or by not resting against a closed glottis can easily result in consistently increased DLCO results of at least five percent.
Similarly, it may give information about the behavior of the glottis and whether glottis function behaves differently in different airway pathologies.
If there is a decreased or absent sensory signal, foreign material in the supraglottis and glottis may escape detection and fail to trigger laryngeal closure.
