Objective:
To evaluate the impact of nasal obstruction on OSAHS.
Method:
One hundred and twenty cases of OSAHS with or without nasal obstruction were analyzed by Hypno PTT(PTT)and Mallampati score (MS); Acoustic rhinometry was measured in all 120 cases.
Result:
A significant correlation was found between the MS and the AHI measured during the sleep (r = 0.266, P < 0.01). The relative risk of OSAHS with a MS of III or IV in the whole group was 1.96, and 2.46 in cases with nasal obstruction.
Conclusion:
A high MS represents a predisposing factor for OSAHS, especially in which associated with nasal obstruction.

Nasal Cannula
A nasal cannula is a lightweight tube split at one end into two prongs and placed in the nostrils. It is typically used to deliver low to medium levels of oxygen.
Suggested flow rate: The suggested flow rate for a nasal cannula typically ranges between 1 and 6 L/min.
