And translation of original without cpap sleep analysis :
Summary – Polysomnography 16/01/2020
Main Diagnosis:
Moderate obstructive hypopneic sleep apnea syndrome (OHSAS)
Apnea-Hypopnea Index (AHI): 24/hour (27/hour including flow limitations)
Predominantly obstructive hypopneas
Arousal-inducing but non-desaturating (mean SpO₂ 92%, minimum 89%, no time < 90%)
Sleep Quality & Structure:
TST: 6h00 / TSP: 7h22 (efficiency 81%)
Stage distribution: N1: 0.6% – N2: 57.4% – N3: 30.2% – REM: 11.8%
Sleep onset latency: 164 min (very delayed)
REM latency: 216 min
Micro-arousals: 185 total (31/hour, normal < 20/hour)
Intra-sleep awakenings: 19 (> 30 s, total 82 min awake during sleep)
Respiratory Findings:
Apneas: 15 (2/hour) — mostly obstructive
Hypopneas: 127 (21/hour) — majority obstructive
Flow limitations: 185 (31/hour)
Supine AHI: 32/hour
Oxygen Saturation:
Mean: 92%
Minimum: 89%
No time below 90%
Other Findings:
Snoring: present 37% of TST, average intensity 87 dB
Heart rate: mean 63 bpm, sinus rhythm, min 49 bpm, max 106 bpm
PLMs: 147 total (12/hour), none during sleep
Conclusion & Recommendations:
Moderate OHSAS with significant sleep fragmentation from frequent respiratory events and micro-arousals.
Suggest management with CPAP or mandibular advancement device.
Avoid evening alcohol and muscle relaxants.
Maintain healthy body weight.
