    Improving Sleep Apnea Treatment through Telemonitoring

    Sleep apnea is a chronic condition that is often underdiagnosed, impacting the quality of life and presenting secondary risks. In France, approximately 5% of the adult population is affected. The primary treatment relies on nocturnal positive airway pressure ventilation (CPAP). The main challenge lies in ensuring compliance with this treatment, as it is crucial for its effectiveness. However, despite significant technical advancements, this device is still poorly accepted and tolerated by patients. Telemonitoring represents a complementary solution that can significantly enhance sleep apnea treatment.


    Diagnosis and Underdiagnosis of Sleep Apnea

    Clinical Indicators of Sleep-Related Breathing Disorders


    Obstructive sleep apnea syndrome (OSAS) involves repeated episodes of airway obstruction in the upper respiratory tract, leading to breathing pauses. Complete blockage results in apneas, while partial blockage leads to hypopneas.


    Loud snoring, restless and non-restorative sleep, and daytime sleepiness are common signs that suggest a diagnosis. Fatigue upon awakening affects the overall well-being, both physically and mentally, with an impact on social life.


    However, the link between these symptoms and the possibility of OSAS is not always recognized, leading to a significant rate of underdiagnosis.


    Consequences and Risks of Sleep Apnea


    In addition to significantly affecting the quality of life, untreated and severe sleep apnea exposes patients to various health consequences:

    • Cardiovascular diseases: cardiac arrhythmias, high blood pressure, and stroke.
    • Type 2 diabetes: 30 to 35% of individuals with diabetes also have sleep apnea, indicating the need for systematic screening.
    • Attention disorders with an increased risk of car accidents.
    • Depression.


    Complementary examinations to confirm the diagnosis of SAHOS

    To establish a diagnosis and provide appropriate treatment, additional tests are necessary. Home-based polygraphy records respiratory parameters during the night. This telemonitoring system serves as a preliminary diagnostic examination, facilitating the screening of OSAS.


    Polysomnography, also known as sleep recording, is a more comprehensive examination that analyzes sleep patterns along with respiration. It can be performed at home or in a healthcare facility, confirming the diagnosis and providing detailed information on its severity.


    Sleep Apnea Treatment with CPAP Ventilation and its Limitations

    Effective Treatment Early intervention helps prevent the consequences of sleep apnea.


    Continuous positive airway pressure (CPAP) therapy is currently the only proven treatment for severe OSAS. By keeping the upper airways open, this treatment reduces the number of apneas and hypopneas. Its effectiveness has been demonstrated in numerous studies.


    The patient’s adherence to CPAP treatment determines its effectiveness. Therefore, the choice of respiratory assistance device, selection of the most suitable mask, adjustment of device parameters, etc., are all crucial aspects. The healthcare provider plays a crucial role in the treatment’s implementation, which requires a period of 1 to 2 weeks for adaptation. Initially, it is essential to verify the correct and regular use of the CPAP device at home. Telemonitoring allows data transmission to the healthcare provider for better adjustment.


    Regarding lifestyle, patients should be encouraged to lose weight as obesity and overweight are aggravating factors. Other factors that contribute to sleep apnea include alcohol consumption and sedative use. In cases of mild to moderate sleep apnea, mandibular advancement devices (MAD) can be tried as a priority.


    Compliance Challenges

    Respiratory devices can be noisy and cumbersome for patients, potentially causing discomfort for both the patient and their partner. Patients often make an initial effort but become discouraged by what they perceive as a complex and restrictive device, resulting in low compliance or discontinuation of its use.


    When compliance is insufficient, it is crucial to identify the reasons, which can vary significantly.


    Importance of Adequate Sleep Apnea Management

    Therapeutic education is now a fundamental aspect of managing chronic diseases. Active patient involvement in their treatment is a key component of successful management.


    A few years ago, a participatory consultation involving professionals (doctors, manufacturers, healthcare providers), and patients led to proposals aimed at improving the follow-up and support of patients with sleep apnea. Among the suggested solutions to improve treatment adherence, telemonitoring offers positive aspects.


    Furthermore, while improving the patient’s health remains the central objective, cost containment in the context of sleep apnea is also crucial.


    Remote Patient Monitoring: a new way to manage sleep apnea

    An Effective Solution for Treatment Adherence Issues


    The complexity of managing OSAS has led to the consideration of telemonitoring as a tool to support and encourage patients to comply with their treatment.


    Since early 2018, telemedicine has been regulated for sleep apnea syndrome, requiring the involvement of a physician. Telemonitoring complements the ongoing care and the doctor-patient relationship without replacing follow-up consultations.


    Chronolife positions itself as an expert partner in remote medical monitoring for sleep apnea treatment. Through direct respiratory rate monitoring, it becomes possible to demonstrate to non-compliant patients that the number of apneas is higher, thereby motivating them to reinitiate treatment.


    Assessing Treatment Efficacy with CPAP

    In addition to providing information on compliance, telemonitoring provides physicians with data to measure treatment effectiveness through indicators such as leaks, pressures, and residual apnea-hypopnea index (AHI). Telemonitoring complements the patient’s medical record, allowing for fine-tuning of parameters if necessary, ensuring tolerance, and addressing any adverse effects.


    Ultimately, this additional information helps in more effectively assessing the balance between benefits and risks and the satisfaction of the patient’s needs.


    The management of OSAS is crucial due to its potential impact on the apneic patient. In a strengthened relationship of trust, telemonitoring allows patients and physicians to adjust the treatment together.
