Observational playback and optional musical sonification only. Node colors are visual signal mappings, not clinical alarms. The atlas samples synchronized source values at 10 Hz; opened waveform charts and derived breath measures use the full 50 Hz feed. PIFR is maximum positive flow; PEFR is the magnitude of minimum negative flow. Peak pressure is the maximum pressure sample. PEEP is estimated from the final five pressure samples when expiration is present. MAP means mean airway pressure, calculated as the time-weighted pressure average over the complete sampled breath; it is not mean arterial pressure. Calculated volume integrates signed flow in L/min within each marked breath; positive flow is inspiration. VTi and VTe sum positive and negative portions separately. Breath-relative volume resets at each breath start, while VTi minus VTe is retained for completed breaths. Missing or invalid intervals have no derived breath measures. Most time axes are estimated from numeric sample index at 50 Hz; the one timestamped recording uses its sample timestamps for integration. No change detection, clinical interpretation, or live patient connection. Unit and room names are virtual assignments, not real hospital locations or confirmed patient identities. Date-like filenames are shifted and do not establish a shared patient timeline. Mode words are filename annotations, not a measured mode channel.
