| Most patients will maintain airway patency although some may require intubation with mechanical ventilation. |
| Fallopian tube patency can be confirmed by detecting an enhanced signal after instilling microbubbles into the uterine cavity. |
| But the possibility of natural conception depends on the tubal patency and ovulatory function. |
| Upper airway patency during sleep is determined, in part, by the tonus of pharyngeal dilator muscles. |
| If non-invasive evaluation is chosen, the sponsor must justify its use and relevance in the assessment of vessel patency. |
| Consequently, aggressive endovascular and surgical techniques may be required to restore vessel patency and to preserve neurological function. |
