After
a complete in-office demonstration, the patient takes home a SNAP digital
recording system including a sound collection cannula and oximetry sensor.
No technician is required for equipment setup. Data collection is performed
in the comfort of the home where the patient places the SNAP sound and air
flow collection device on their upper lip to collect oral and nasal respiratory
sound and airflow information for up to 7 hours. However, periods shorter
than seven hours may be all that is necessary for analysis.
In
addition, an oximetry sensor is placed on a finger and all data is digitally
recorded during sleep. The recorded data is returned to our laboratory where
analysis is performed using SNAP's proprietary FDA cleared computer technology
and software algorithms. Trained technicians and medical consultants review
all data and a report is prepared and forwarded to the referring physician.
The analysis includes information about the apnea (A), hypopnea (H), apnea
hypopnea index (RDI), acoustic spectral profile of snoring, oxygen saturation
and pulse rate.
