From the Guidelines
For a patient with Obstructive Sleep Apnea (OSA) on AutoPAP therapy with pressures 5-20 cmH2O showing an AHI of 9-10, the next steps should include optimizing therapy to achieve better control of apnea events, as recommended by the American Academy of Sleep Medicine 1. First, download and review the detailed data from the AutoPAP device to identify specific patterns of events, leak issues, and pressure requirements. Consider narrowing the pressure range to a fixed CPAP setting based on the 90th or 95th percentile pressure that effectively controls most events. Ensure proper mask fit and address any mask leaks that may be compromising therapy effectiveness. The patient should be scheduled for a follow-up appointment within 1-3 months to reassess symptoms and review device data. Lifestyle modifications should be reinforced, including weight loss if applicable, avoiding alcohol and sedatives before bedtime, and maintaining good sleep hygiene. If these adjustments don't improve the AHI to below 5 events per hour, consider a repeat sleep study to evaluate for residual events or the need for alternative therapies such as bilevel PAP therapy or an oral appliance, as suggested by recent guidelines 1. Some key points to consider in managing OSA include:
- The importance of ongoing PAP therapy for patients with OSA, even if used for less than 4 hours per night 1.
- The consideration of alternative therapies for patients who cannot tolerate or adhere to PAP therapy, such as mandibular advancement devices or surgical options 1.
- The role of educational, behavioral, and supportive interventions in improving PAP adherence, particularly for patients at high risk of poor adherence 1. The goal of therapy is to reduce the AHI to less than 5 events per hour, as persistent elevated AHI values of 9-10 indicate suboptimal control that may continue to impact cardiovascular health, daytime alertness, and quality of life.

Next Steps for Patient with OSA on AutoPAP
The patient with Obstructive Sleep Apnea (OSA) on AutoPAP therapy with pressures 5-20 cmH2O, showing an Apnea-Hypopnea Index (AHI) of 9-10, requires further evaluation and potential adjustments to their treatment plan.
- Assessment of Treatment Efficacy: The current AHI of 9-10 indicates that the patient's OSA is not being adequately controlled by the AutoPAP therapy 2.
- Troubleshooting Residual AHI Elevation: Drug-induced sleep endoscopy during PAP application (DISE-PAP) can be used to examine the anatomic effect of PAP therapy on the upper airway and troubleshoot refractory residual AHI elevation 2.
- Alternative PAP Devices: Consideration of alternative PAP devices, such as BiPAP or adaptive servo-ventilation (ASV), may be necessary for patients who are nonadherent to CPAP or APAP therapy due to pressure intolerance 3, 4.
- Adjustments to Current Therapy: Adjustments to the current AutoPAP therapy, such as changes to the pressure settings or the use of a different mask or interface, may be necessary to improve treatment efficacy 5, 4.
- Monitoring and Follow-up: Regular monitoring and follow-up are essential to assess the effectiveness of the treatment plan and make any necessary adjustments 6, 3.
Considerations for Choosing the Best PAP Device
When choosing the best PAP device for the patient, several factors should be considered, including:
- Associated Symptoms and Comorbid Medical Problems: The presence of associated symptoms, such as daytime sleepiness, and comorbid medical problems, such as cardiopulmonary disease, should be taken into account when selecting a PAP device 3, 4.
- Cost and Access to Online Data Management: The cost of the device and access to online data management and patient portals should be considered when choosing a PAP device 4.
- Portability of the Device: The portability of the device is an important consideration for patients who travel frequently 4.
