Diagnostic & Treatment Methods

The Wellmax Sleep Center offers a unique portfolio of services to diagnose and treat patients with sleep disorders. We use a multidisciplinary approach that brings together several diagnostic and therapeutic modalities. This platform provides the most comprehensive and cost effective means of meeting patients’ needs.

Consultation or Direct Referral Primary

Care physicians and specialists can request a sleep consultation or may make a direct referral for a specific test. Our sleep center staff is available for brief telephone consultation to discuss specific patients to help guide the referral into a best test direct referral and to explain our unique diagnostic options.

Polysomnography (Overnight sleep study)

Polysomnography, the simultaneous recording of neurologic and physiologic parameters is an overnight test performed on sleeping patients. Polysomnography generally includes monitoring of the patient’s airflow through the nose and mouth, electrocardiographic activity (ECG), blood oxygen level (SpO2), brain wave pattern (EEG), eye movement (EOG), and the movement of respiratory muscles and limbs (EMG). Polysomnography is used to help diagnose and evaluate a number of sleep disorders such as sleep apnea, narcolepsy, parasomnias and to detect and evaluate seizures that occur during the night. All waveforms are recorded and the patient is monitored by the sleep technician via computer; the resultant study is then scored by a technician for physician review and interpretation.

Ambulatory Portable Monitoring

Portable monitoring, which has been available for 10 years, is the simultaneous recording of physiologic parameters in an overnight test to evaluate sleep disordered breathing. Sleep disordered breathing by the American Academy of Sleep Medicine (formerly the American Sleep Disorders Association), includes central, mixed, and obstructive apnea and hypopnea syndrome. Physiologic parameters include the ECG, respiratory effort, airflow, saturation, pulse waveform and body position. These unattended studies are done at home and may be performed in any setting; i.e., a nursing home or assisted living facility. They are especially useful for patients who may be physically unable to come to the lab or if the lab is booked and you are strongly suspecting OSAHS as the problem. Ambulatory portable monitoring studies are diagnostic screening studies and if they are abnormal they are followed up with an in lab CPAP or BiPAP titration study. This process ensures that the home unit will meet insurance requirements for payment.

Auto-Titrating (C-PAP) Continuous Positive Airway Pressure Devices

Continuous positive airway pressure (CPAP) has been used to treat patients with obstructive sleep apnea syndrome (OSAHS) utilizing a fixed single pressure. Auto-titrating CPAP has been available since 2000, and these units automatically titrate positive airway pressure (APAP) to maintain airway patency. These devices are used for titration (APAP titration) and treatment (APAP treatment). These are self-adjusting, record pressure data and compliance (smart technology) and the data is downloadable for interpretation and reporting.

BiPAP Continuous Positive Airway Devices

BiPAP stands for bi-level positive airway pressure. It is a CPAP unit but differs to the extent that the proximal airway pressure is reduced during the exhalation phase of breathing. The unit senses the slight increase in back pressure during exhalation and the pressure reduces to facilitate exhalation. Typically, BiPAP is used for patients who cannot tolerate conventional CPAP and for those on higher CPAP pressures. BiPAP is also used for patients with CHF (congestive heart failure) and those with chronic lung disease, i.e. asthma, emphysema and COPD.


Adapt SV is an adaptive-servo ventilator designed specifically to treat central sleep apnea (CSA) in all its forms; including complex and mixed sleep apnea. Adapt SV normalizes breathing, completely suppressing CSA and/or Cheyne-Stokes respiration (CSR)
