PSG with CPAP Titration - General monitoring and diagnostic evaluation is conducted on the first night. If Sleep Apnea is discovered, the patient returns for a second night to determine the necessary CPAP pressure required to alleviate apnea.
Split Night PSG with CPAP Titration - Split Night PSG is conducted when moderate or severe Sleep Apnea has been discovered or strongly suspected during the first part of the nights study. The second half of the night is used for CPAP Titration.
A CPAP Titration is required if sleep apnea is diagnosed or strongly suspected. Typically, this is a full night of study performed during a second night, but is sometimes performed during the last few hours of a split-night study. During the titration study, the technician will set the air pressure on the CPAP at a certain level and then watch the resulting measurements. If that pressure does not reduce the number of apnea and hypopnea events, or eliminate the snoring, the technician will adjust the air pressure and continue observation. This process continues throughout the night until the optimum pressure is reached.
CPAP (Continuous Positive Airway Pressure) therapy is the first line of treatment for sleep apnea. The CPAP device delivers pressurized air through tubing to a nasal mask or nasal pillows, which are fitted around the head. The pressurized air acts as an airway splint. It gently opens the patient's throat and breathing passages, allowing them to breathe normally while asleep.
