Methods： Choosed 153 patients with OSAHS from March 2010 to March 2012，investigation the cognition degree and treatment intentionality of patients to OSAHS，conducted statistical analysis with investigation results. Results： The cognition degree of patients to OSAHS was still on low level，the proportion was 53.6% for holding OSAHS as disease，and 47.8% patients thought it need treatment. 47.8% patients agreed to use CPAP treatment，the agreement was higher for AHI>15 and 35-55 years old（60% and 56.45% respectively），the main reasons for disagreement were the price of respirator，the feeling of unsafety，inconvenjence，discomfort，or preference for operation，among them，especially the price of respirator. Reliability measuring scale showed the high score had high proportion，on added questions，90% choosed negative answers. Conclusion： The cognition degree is low for OSAHS patients to disease，the acceptance is bad，the high price of respirator and low trust rate to doctors are important influencing factors on treatment acceptance of OSAHS patients.
