Preliminary Appraisal
ESS is a self-administered questionnaire for those who suspect they may suffer from a sleep disorder, reduced mental function throughout the day, and other effects of poor sleep quality.
This questionnaire is a test to help you gauge your risk for obstructive sleep apnea. It also helps doctors to determine whether patients need to undergo a sleep apnea test.
Sleep Apnea Check

Sleep Apnea Test 1
Nasopharyngeal Endoscope
The doctor will initially find out where the airway obstructions are. This can be done during the day when the patient is awake. Assessment can be performed in the clinic, and the process takes around five minutes to complete.
Aims
Find out where the airway obstructions are, during the day when the patient is awake.
Method
First, a small amount of anesthetic is sprayed into the patient’s nostrils. The endoscope is extended from the nostrils to the nasal cavity, throat, and hypopharynx, in order to observe the condition of the entire respiratory tract.
Location
In the clinic
Sleep Apnea Test 2
Sleeping Throat Endoscope
The doctor will initially find out where any airway obstructions are. This can be done when the patient is asleep. While the patient is sleeping, it’s possible to find the position of a blockage, detect the number of obstructions and the time obstruction occurred.
Aims
Accurately locate the blockage during sleep.
The number and duration of blockages is detected.
Method
The doctor puts the patient to sleep before the operation. They observe the condition of the entire respiratory tract while the patient is asleep, by extending the endoscope from the patient’s nostrils into the nasal cavity, throat, and hypopharynx.
Location
In the hospital
