Outline of Final Research Achievements

This study aimed to develop new strategies for perioperative airway and respiratory management for patients with sleep disordered breathing. First, we investigated possibility of using nasal cannula pressure for detecting obstructive disordered breathing as a postoperative respiratory monitor. We found that patterns of the respiratory signals obtained from the nasal cannula during obstructive breaths could be automatically detected and used for development of postoperative respiratory monitor. Second, we tested whether application of negative external pressure to the submental region decreases collapsibility of the passive pharynx in anesthetized subjects. We found that it was effective in non-obese subjects but not in obese subjects. We concluded that the submental negative pressure application could be an alternative treatment for postoperative obstructive events particularly in non-obese subjects who rejected nasal CPAP treatment.
