Advanced Sleep Consultation

After Dr. Grande has reviewed your online questionnaire results he will make an appointment with you for the next step in the Risk Assessment process. Should you decide to proceed, several risk assessment tests will be conducted in our office as part of an advanced sleep consultation.

These tests use two state-of-the-art electronic measurement devices that assess the air volume capacity of your nasal and throat passages and whether or not these are easily susceptible to obstruction during sleep.

Rhinometer

Rhinometer

The first device is called a rhinometer which measures the size of your nasal passages.  The device gathers information using acoustic reflection. Sound waves are sent up the nasal passageway and they are reflected back out in such a way that the device can accurately map out the topography of the nasal airway. This allows us to clearly identify the location and severity of any obstruction in the airway. The test takes approximately 60 seconds to complete.

Pharyngometer

Pharyngometer

The other device is called a pharyngometer and does the same thing with your throat passage.  It is used to determine your airway size and stability as studies show a clear relationship between the existence of sleep apnea and a narrow, collapsible airway. The pharyngometer accomplishes these measurements using acoustic reflection technology, similar to a ship’s sonar. Sound waves are projected down the airway and reflected back out in such a way that the equipment’s software can analyze and measure changes in your airway’s size while breathing. The test takes 2-5 minutes.

If these tests indicate a likelihood of sleep apnea, the next step is go onto a sleep study to get the definitive answer.  This is something you can get at a sleep lab or we can provide you with our take-home sleep study device and you can do it at home.
