  • Comprehensive Sleep Therapy AASM Guidelines and what to make of them1/21/12 Randy Clare and Associates 1
  • Who is Randy Clare Anyway• 1990’s – The Silencer• 2000 – The Diagnostic years – SensorMedics – Viasys – Cardinal Health – CareFusion – CPAP Accessories DME• 2011 – SleepScholar – – Scottsdalestudyclub.com1/21/12 Randy Clare and Associates 2

  • Positive airway pressure is the treatment of choice for mild moderate and severe OSA and should be offered as an option to all patients1/21/12 Randy Clare and Associates 5
  • 1/21/12 Randy Clare and Associates 6
  • OSA Patient Diagnostic & Therapy Flow Patient Motivated to Seek Help Other Specialist Primary Care Physician Self Referral 10% 80% 10% Specialist Assessment Pulmonologist Neurologist Otolaryngologist Psychologist/ Dentist 80% 10% (ENT surgeon) Psychiatrist 5% Diagnostic Stage at Sleep Lab or in Home Attended Sleep Lab Unattended Study – Home (USA) SNS PSG PPSG HST Device Diagnosis for half of the Full sleep study in a Less sophisticated studies Studies carried out at the night and therapy for the sleep laboratory requiring simpler analysis patients home. Attended or second half unattended Therapy typically provided by Home Care Provider CPAP Device Masks (2-4 per year)1/21/12 Randy Clare and Associates 7
  • CPAP at DME• Competitive bidding is driving consolidation of providers (easy for payors not easy for patients)• Largest DME providers are Lincare, Apria, Rotech• 15-20% of Sleep Labs are now dispensing CPAP1/21/12 Randy Clare and Associates 8
  • CPAP at Dental Office?• Who better than a dentist• Need an RT due to the Pharmacy Board rules• 3 month recall• Steady income Stream• Unequivocal participation in the medical model• Therapeutic neutrality fits the patient expectation of superlative care1/21/12 Randy Clare and Associates 9
  • Mask Replacement• Ideally every 6 months• Minimum yearly• Insurance dictates• Notify customer• Compliance Program• Select a reasonably priced mask1/21/12 Randy Clare and Associates 10
  • HOW OFTEN DO YOU REPLACE YOUR MASK? n= 2800 patients• 5% - Every 3 months• 16% - Every 4 to 6 months• 14% - Every 7 to 9 months• 18% - Less than once a year• 48% - Never* TalkAboutSleep.Com Survey n=28001/21/12 Randy Clare and Associates 11
  • Cleaning & Care of Mask• Select simplistic mask• Instruct on cleaning daily / weekly / monthly mild lanolin free soap no creams or Vaseline no rubbing alcohol no abrasives clean in A.M. rinse well1/21/12 Randy Clare and Associates 12
  • HOW OFTEN DO YOU CLEAN YOUR MASK?HOW OFTEN DO YOU CLEAN YOUR MASK?• 26% - Daily• 7% - 4 to 6 X per week• 22% - 1 to 3 X per week• 27% - 1 to 4 X per month• 15% - less than once a month• 4% - never* TalkAboutSleep.Com Survey n=28001/21/12 Randy Clare and Associates 13
  • If CPAP use is considered inadequate based on objective monitoring and symptom evaluation, prompt and intensive efforts should be implemented to improve PAP use or consider alternative therapies.1/21/12 Randy Clare and Associates 14
  • Weight loss should be recommended for all overweight OSA patients. Weight loss should be combined with a primary treatment of OSA, Because of the low success rate of dietary programs and the low cure rate by dietary approach alone.1/21/12 Randy Clare and Associates 15
  • Sleep position can affect airway sizeand patency with a decrease in thearea of the upper airway, particularlyin the lateral dimension, while in thesupine position. Positional therapy, consisting of a method that keeps the patient in a non supine position is an effective secondary therapy or can be supplement to primary therapies for OSA in patients who have a low AHI in the non supine versus that in the supine position1/21/12 Randy Clare and Associates 16
  • Behavioral Strategies• Weight loss• Exercise• Positional Therapies• Avoidance of Alcohol and Sedatives1/21/12 Randy Clare and Associates 17
  • Background• Obesity is the most powerful risk factor for obstructive sleep apnea (OSA)• Obesity is essentially the only reversible risk factor• Potentially modifiable risk factors for OSA also include alcohol, smoking, nasal congestion, and estrogen depletion in menopause.• Data suggest that obstructive sleep apnea is associated with all these factors, but at present the only intervention strategy supported with adequate evidence is weight loss. ( Young et al. 2002)1/21/12 Randy Clare and Associates 18
  • Obesity and OSA• About 70% of those with OSA are obese (Malhotra et al 2002)• Prevalence of OSA in obese men and women is about 40% (Young et al 2002)• Higher BMI associated with higher prevalence – BMI>30: 26% with AHI>15, 60% with AHI>5 – BMI>40: 33% with AHI>15, 98% with AHI>5 (Valencia-flores 2000)1/21/12 Randy Clare and Associates 19
  • Obesity and OSA• Total body weight, BMI, and fat distribution all correlate with odds of having OSA – Every 10 kg increase in weight increases risk by 2X – Every increase in BMI by 6 increases risk by 4X – Every increase in waist or hip circumference by 13 to 15 cm increases risk by 4X (Young et al 1993)1/21/12 Randy Clare and Associates 20

  • A PM should at minimum, record airflow, respiratory effort, and blood oxygenation. The type of biosensors used to monitor these parameters for in-laboratory PSG are recommended for use in PMs and include an oronasal thermal sensor to detect apneas, a nasal pressure transducer to measure hypopneas, oxymetry, and ideally, calibrated or uncalibrated inductance plethysmography for respiratory effort (RIP). (Consensus)1/21/12 Randy Clare and Associates 24

  • Measuring Bruxism Software SetupElectrode Placement1/21/12 Randy Clare and Associates 28
  • Sample Bruxism Report There was bruxism, snoring, apneas and hypopneas associated with arterial oxygen desaturations. The number of bruxism events was 45 providing ABI of 0.9. The overall apnea/hypopnea index (AHI) was 17.5. The supine apnea/hypopnea index was 17.5. The mean arterial oxygen saturation was 94%. The lowest arterial oxygen saturation was 86% Findings are consistent with1. Severe sleep related bruxism 327.532. Moderate obstructive sleep apnea syndrome 327.23. Recommendations: Since the ABI is relatively high, consider a dental consultation for an oral appliance. This patient has moderate OSA. Therapeutic options include: The patient may benefit from the use of a nocturnal mandibular repositioning – appliance. If that line of therapy is to be pursued, the patient should be evaluated by – a dentist specialized in the treatment of sleep related breathing disorders taking into – account the presence of Bruxism….

  • Three things to consider for Monday• Do I consider Bruxism when I consult sleep patients? Sleep for Bruxism patients?• When I talk sleep do my eyes wander to Neck? Hips and Belly? Do I estimate BMI?• Should I talk to my office manager about our attitude around CPAP? Is there a local DME I can work with? Should I consider providing CPAP?1/21/12 Randy Clare and Associates 31
