| Do you snore? |
| The absence of snoring makes it very difficult to arrive at a diagnosis of OSA. If the answer is yes, or don’t know, continue to the following questions |
| Has anybody remarked to you on any occasion that you stop breathing when you are sleeping? |
| Isolated apnoeas are very common in snorers, but prolonged or repeated apnoeas witnessed by somebody accompanying the patient are highly indicative of OSA |
| Do you sleep during the day more easily than you think is normal? |
| Hypersomnia is also a very common occurrence, but when it is accompanied by snoring or apnoeas, without any apparent cause, or by cardiovascular manifestations it must be investigated, and if it is accompanied by decapacitating forms, association with high-risk professions or a great cardiovascular risk it requires a preferential referral |
