Spo2 Assistant 3.1 ^hot^ <CONFIRMED ⟶>

For the first time in the Assistant line, version 3.1 displays raw Photoplethysmography (PPG) waveforms. Clinicians can analyze the shape of the arterial pulse wave to detect arrhythmias (specifically Atrial Fibrillation) by measuring the variability in the peak-to-peak interval. While not a substitute for an ECG, it serves as an excellent screening tool.
