2 Outline Sleep-Disordered Breathing Case Studies CHF Anagrams Questions Tx Ghosts?
3 60 yo Diabetes Hypertension Ischemic heart disease MI -> CABG LVEF = 40% BMI = 60 Bordier et al, Chest, 2004
4 Presentation Chronic Heart Failure Respiratory Acidosis O 2 = 0.5 L/min NC ph 7.31 PaCO 2 82 mmhg PaO 2 40 mmhg HCO 3 40 mmol/l BE 10.2 O 2 Sat 67% Bordier et al, Chest, 2004
5 Home Sleep Test Found dead on morning after HST Severe CSA (AHI = 93.3) No OSA Mean O 2 sat = 58% No cardiac arrhythmias 8h of constant CSR during sleep, then Respiratory arrest 7 min later, asystole. Bordier et al, Chest, 2004
6 Cheyne Stokes Breathing Rule Score if 3 consecutive cycles of cyclical crescendo and decrescendo change in breathing amplitude and at least 1 of the following: 5 CAs or hypopneas per hour of sleep The cyclic crescendo and decrescendo change in breathing amplitude has duration of 10 consecutive minutes. AASM Scoring Manual, 2007

10 Clinical Guideline for the Evaluation, Management and Long-term Care of Obstructive Sleep Apnea in Adults Epstein et al, J Clin Sleep Med, 2009
11 Adult OSA AASM Task Force Recommendations: OSA questions in routine health evals OSA suspicion should trigger sleep eval Diagnosis should include: Sleep-oriented H&P Objective testing Patient education Epstein et al, J Clin Sleep Med, 2009
12 Task Force Recommendations OSA presence and severity must be determined before tx. Include patient in appropriate tx. OSA should be approached as a chronic disease. With tx, describe: Appropriate outcome measures. Long-term follow-up. Epstein et al, J Clin Sleep Med, 2009
