Sleep apnea is a serious sleep disorder characterized by pauses in breathing during sleep. It often results from a narrow throat area and can lead to severe health issues. Types include Obstructive, Central, and Complex Sleep Apnea. Symptoms range from loud snoring and gasping to daytime irritability and increased risk of heart disease. Treatment options vary from CPAP machines delivering pressurized air to surgical interventions. Given its prevalence, affecting around 18 million Americans, awareness and understanding are crucial for effective management.

  1. Sleep Apnea John Paquet III BME 281 S01 02 October 2013

  2. What Exactly is Sleep Apnea? • Apnea (“want of breath”) = a pause in breathing • Narrower throat area • When muscles in upper throat relax during sleep, airway becomes blocked • Results in repeating pattern of heavy snoring, a silent period, and a gasp

  3. Types of Sleep Apnea • Obstructive Sleep Apnea • Most common kind of sleep-disordered breathing • Central Sleep Apnea • Imbalance of respiratory control centers in brain during sleep • Controls fail to give signal to inhale, resulting in missed cycles of breathing • Complex/Mixed Sleep Apnea • Combination of obstructive and central

  4. Facts • Each apnea can last from 10 seconds to minutes • 5 to 30 or more apneas per hour • Affects around 18 million people in US, many of whom are unaware that they have the condition

  5. Causes • Obesity • Large neck • Large tongue • Short lower jaw in comparison with upper jaw

  6. Symptoms and Potential Risks • Irritability and impatience • Forgetfulness • Drowsiness • Headaches • Increased risk of: • High blood pressure • Heart disease • Stroke

  7. CPAP • Continuous Positive Airway Pressure • Small machine delivers stream of pressurized air through tube to mask • Traditional CPAP machines require patient to input desired pressure (determined from a sleep study) • APAP automatically changes air pressure as necessary to minimize number of apneas • Can even warm/humidify air and monitor breathing

  8. CPAP (Continued) • Advantages: • Better mood, better memory, higher alertness during day, increased productivity, regular sleep patterns • Disadvantages: • Eye irritation, nasal congestion, dry or sore mouth • These can typically be remedied by humidification, keeping CPAP equipment clean, and choosing the right mask

  9. Oral Devices and Surgery • Mandibular advancement splint • Uvulopalatopharyngoplasty (UPPP or UP3) • Removes excess tissue at back of throat • Base-of-tongue advancement • Maxillomandibular advancement

  10. Discussion • CPAP machines are far less expensive than surgery • Even if apnea is cured, surgical procedures pose potential risk of creating complications (i.e. via infection, nerve damage-TMD) • Dental appliances can be around the same cost or even cheaper than CPAP, but are less effective and only treat mild to moderate obstructive sleep apnea • CPAP is most common, effective, non-invasive treatment for patients with moderate to severe sleep apnea
