| The glottis suddenly closes and stops the inflow of air resulting in the sound of a hiccup. |
| Pass the deflated cuff along the right side of the blade through the visualized glottis. |
| Then the blunt wire was introduced inside the trachea when the glottis was open. |
| The diagnosis is definitively established by visualization of the glottis when the patient is symptomatic. |
| Hiccups in dogs, just as in people, are caused when a spasm of the muscular diaphragm creates a sudden inhalation followed by a closure of the glottis. |
