Neonate with Cyanosis - Approach

[Intro: 135 BPM. The track opens with a single, heavy 909 kick drum pounding on every quarter note. A synthesized "boot-up" sound echoes across the stereo field. The robotic AI voice announces the program title with a heavy delay effect.] NEONATE WITH CYANOSIS APPROACH [Phase 1 / The Baseline Logic: A sharp, echoing clap joins the kick drum. The acid bassline begins to bubble quietly in the background. The AI delivers the first data points with staccato precision.] arterial oxygen pressure higher 80, Unlikely to be cyanotic If there is a differential cyanosis differential cyanosis differential cyanosis More than 10 percent difference in saturations between right hand and lower extremity It means pulmonary hypertension. [Phase 2 / The Right-Hand Algorithm: The acid bassline suddenly opens up, becoming loud, squelching, and aggressive. The hi-hats start ticking rapidly. The AI voice splits into a dual-harmony, simulating the branching of the algorithm.] If right hand is higher If chest x ray positive, it means persistent pulmonary hypertension of the new born or respiratory distress syndrome No x ray plus Pulmonary congestion + cardiomegaly means Systemic outflow tract obstruction like coarctation, critical aortic stenosis Pulmonary congestion but no cardiomegaly means pulmonary outflow tract obstruction like total anomalous pulmonary venous return [Phase 3 / The Leg Override: The bubbling bassline momentarily drops out, leaving just the heavy drums and a warning-siren synthesizer. The AI delivers this short override code.] If leg is higher, it means TGA with PH or coarctation [Phase 4 / The Null Differential: The track hits its peak. The bassline returns at maximum intensity. A sweeping synth filter creates a massive, stadium-techno build-up. The AI rapidly fires off the final, complex diagnostic paths without breaking rhythm.] No differential cyanosis means No differential cyanosis No differential cyanosis means pulmonary disease if x ray shows focal changes Pulmonary outflow tract obstruction like pulmonary atresia, tetralogy of Fallot, Ebstein, tricuspid atresia if x ray shows pulmonary edema If no edema, Complete mixing lesion with an unrestrictive ASD like TGA, HLHS, mitral atresia, single ventricle complexes [Ending: The heavy drumbeat and squelching bassline instantly stop. A single, crystalline digital bell rings out. The AI voice says "complexes" one final time, pitched down octaves until it sounds like a dying machine, fading into total silence.]
