Your CPAP Titration Night
A CPAP titration study is an overnight test in a sleep lab where a technologist adjusts your CPAP pressure to find the optimal setting for treating your sleep apnea. This is typically done after your diagnostic sleep study has confirmed a sleep apnea diagnosis.
Before You Arrive
- Follow the same preparation guidelines as a diagnostic sleep study
- Avoid caffeine and alcohol
- Bring comfortable sleepwear and your usual bedtime items
- If you have a mask preference, let the sleep lab know in advance
During the Study
The setup is similar to a diagnostic sleep study, with the addition of a CPAP mask:
- The technologist helps you try different mask styles to find the best fit
- All standard sleep monitoring sensors are applied
- CPAP is started at a low pressure once you're ready to sleep
- Pressure is gradually increased to eliminate apneas and hypopneas
- The technologist monitors mask fit and adjusts as needed
Finding Your Optimal Pressure
The goal is to find the lowest pressure that effectively eliminates your breathing events in all sleep positions and sleep stages, including REM sleep when apnea is often most severe. The technologist also ensures the pressure doesn't cause excessive mask leak or discomfort.
After the Study
Your sleep physician reviews the data and determines your prescribed pressure. This prescription is sent to your equipment provider, who sets up your home CPAP machine. You'll typically have a follow-up appointment to ensure your therapy is working well.
What Is PAP Titration
Understanding PAP Titration
PAP titration is the process of determining the optimal air pressure setting for your CPAP or BiPAP machine. Think of it as "dialing in" the perfect treatment — finding the pressure that eliminates your breathing events without causing discomfort.
How Titration Works
During an in-lab titration study, you'll wear a CPAP or BiPAP mask while a sleep technologist monitors your sleep from a control room. The technologist starts at a low pressure and gradually increases it throughout the night until your apneas, hypopneas, and snoring are eliminated.
What the Technologist Monitors
- Apneas and hypopneas at each pressure level
- Blood oxygen saturation
- Snoring intensity
- Sleep quality and body position
- Mask fit and air leak
Types of Titration
- Full-night CPAP titration — An entire night dedicated to finding the right pressure
- Split-night study — Diagnosis in the first half, titration in the second half
- BiPAP titration — Adjusting two separate pressures (IPAP and EPAP)
- Auto-titration — Using an auto-CPAP machine at home to determine optimal pressure
After Your Titration
Your sleep physician will review the titration data and prescribe the pressure that best controlled your sleep apnea. This prescription is sent to your CPAP equipment provider, who will set up your machine at the correct pressure.
Key Takeaways
- CPAP titration finds the ideal pressure for your specific sleep apnea
- A trained technologist adjusts pressure throughout the night
- The experience is similar to a diagnostic sleep study with the addition of a mask
- Results guide your prescribed CPAP settings for home use
