Split Polysomnography

 

Split Polysomnography combines diagnostic Polysomnography and CPAP titration into one night.  A portion of the night is used to establish that the patient has obstructive sleep apnea using the PSG measurements.

The second portion of the night is used for CPAP titration to determine the optimum pressure.  CPAP titration requires approximately two hours.  Pulmonary and Sleep Associates of Huntsville strive to perform diagnostic PSG and CPAP titration on the same night whenever possible.  There are reasons why performing diagnostic polysomnography and CPAP titration on the same night are either not possible or not desirable.
