Justifying ASV

It is very likely that you are here because someone referred you here because after reviewing your Sleepyhead daily charts and/or your Sleep Studies they felt that you are a candidate for an Advanced PAP machine such as one of the Bi-Levels. There are two paths to treatment and the choice is yours.

Path 1: The path that you were thrown into whether you realize it or not. That is to treat your apnea, whatever types of apnea that you have, with the machine they gave you, a CPAP, preferable an auto-CPAP either the ResMed or the Philips Respironics machines. New members of the forum come here looking for help with intractable apnea and discomfort from these problems. The forum members and "gurus" are very good at optimizing therapy to reduce these problems, and increase comfort with the therapy.

Path 2: Take the often difficult and lengthy journey to procure an advanced PAP machine. The new member that has been advised they have central or complex apnea needs to be aware that optimizing may provide significant immediate relief from symptoms and improve AHI, but improved therapy results can disqualify them from higher levels of therapy (ASV), that might be possible without this self-optimization. Sometimes individuals resolve central and complex apnea with CPAP and find long-term comfort, however, if results are inconsistent, or produce good AHI but not comfort or relief from other symptoms, The forum optimization should be discontinued as soon as possible to avoid disqualification from higher levels of therapy. This path frequently requires failing at CPAP, then failing at BiLevel E0470, before succeeding at ASV E0471

ASV or Adaptive servo-ventilation (ASV) The below is based on Medicare Requirements for procuring

• E0470 - RESPIRATORY ASSIST DEVICE, BI-LEVEL PRESSURE CAPABILITY, WITHOUT BACKUP RATE FEATURE, USED WITH NONINVASIVE INTERFACE, E.G., NASAL OR FACIAL MASK (INTERMITTENT ASSIST DEVICE WITH CONTINUOUS POSITIVE AIRWAY PRESSURE DEVICE) (Similar to ResMed Aircurve 10 VAuto)
• E0471 - RESPIRATORY ASSIST DEVICE, BI-LEVEL PRESSURE CAPABILITY, WITH BACK-UP RATE FEATURE, USED WITH NONINVASIVE INTERFACE, E.G., NASAL OR FACIAL MASK (INTERMITTENT ASSIST DEVICE WITH CONTINUOUS POSITIVE AiRWAY PRESSURE DEVICE) (Similar to ResMed Aircurve 10 ASV or ResMed Aircurve 10 ST/A)

Complex Sleep Apnea

For Complex Sleep Apnea the Medicare requirements for issuing an ASV machine.

• Therapy Optimization should be discontinued and the original settings, from the doctor, restored.
• Titrate to minimize OSA, that is the obstructive AHI to less than 5 per hour. This typically is raising EPAP or pressure until obstructive AHI is less than 5 per hour, we expect this to make the Central and Complex Apnea worse thus failing the current treatment
• Record the central apnea-central hypopnea index (CAHI) (looking for greater than or equal to 5 per hour and greater than 50% of total AHI)
• Document the presence of at least one of the following symptoms: These symptoms are specifically noted by Medicare. These are key symptoms that we look for by asking "How do you feel?". Do not limit your answers to the following and do not fabricate the answers.

1. Sleepiness, "How do you feel?"
2. Awakening short of breath, "How do you feel?"
3. Difficulty initiating or maintaining sleep, "How do you feel?"
4. Frequent awakenings, or "How do you feel?"
5. Nonrestorative sleep, "How do you feel?" Nonrestorative sleep is defined as the subjective feeling that sleep has been insufficiently refreshing
6. Snoring, Can be documented on Sleepyhead
7. Witnessed apneas Most of us have this one with our significant others

For Central Sleep Apnea

For Central Sleep Apnea the Medicare requirements for issuing an ASV machine.

• Therapy Optimization should be discontinued and the original settings, from the doctor, restored.
• Document a central apnea-central hypopnea index (CAHI) is greater than or equal to 5 per hour also apnea-hypopnea index (AHI) greater than 5'
• Document The sum total of central apneas plus central hypopneas is greater than 50% of the total apneas and hypopneas
• Document the presence of at least one of the following symptoms: These symptoms are specifically noted by Medicare. These are key symptoms that we look for by asking "How do you feel?". Do not limit your answers to the following and do not fabricate the answers.

1. Sleepiness, "How do you feel?"
2. Awakening short of breath, "How do you feel?"
3. Difficulty initiating or maintaining sleep, "How do you feel?"
4. Frequent awakenings, or "How do you feel?"
5. Nonrestorative sleep, "How do you feel?" Nonrestorative sleep is defined as the subjective feeling that sleep has been insufficiently refreshing
6. Snoring, Can be documented on Sleepyhead
7. Witnessed apneas Most of us have this one with our significant others

Symptoms

Note that these are not all specific to Central/Mixed/Complex apnea. They are symptoms that impact our sleeping, arousals, and yes apnea too. Think of these, but do not limit yourself to these when you are asked "How do you feel?"

• Daytime hypersomnolence;
• Excessive fatigue;
• Morning headache;
• Cognitive dysfunction;
• Dyspnea, etc.;
• Fatigue;
• Insomnia;
• Difficulty going to sleep;
• Difficulty falling asleep;
• Wakening during the night;
• Daytime Sleepiness;
• Excessive Daytime Sleepiness (EDS);
• Poor concentration;
• Difficulty with balance;
• Shortness of breath;
• Dry mouth;
• Restless Sleep;
• Non-Restorative Sleep;
• Snoring;
• Obstructive Sleep Apnea;
• Restless Leg Syndrome;
• Nocturnal Leg Cramps;
