Piku Index Portable -

The Piku Index!

• Net Promoter Score (NPS) scaled 0–100 or Customer Satisfaction (CSAT %)
• Qualitative sentiment score from support tickets or reviews (scale 0–100) Score: combine chosen survey metric and sentiment, average, multiply by 0.3.

Investors have realized that a startup with a high Piku Index (say, 85) can survive a downturn. It doesn't need constant infusions of laxatives (i.e., venture debt). It is profitable, smooth, and resilient. Piku Index

2. Background and Rationale

2.1 The Clinical Problem

• BPH affects ~50% of men aged 51–60 and up to 90% of men over 80.
• Key symptoms include weak stream, hesitancy, intermittency, and incomplete emptying.
• Gold standard tests (uroflowmetry, post-void residual ultrasound) are not always available in primary care, nursing homes, or home settings.

Potential Components of the Piku Index

9. Future Directions

• Digital Piku Index: Smartphone app using microphone or camera to classify stream sound/visual pattern (AI-based).
• Validation studies: Larger multicenter trials correlating Piku Index with urodynamic pressure-flow studies.
• Pediatric adaptation: Modified scale for children with dysfunctional voiding.

In patients with severe head trauma or hemorrhagic stroke, this autoregulation is often impaired. The Piku Index is calculated using a ratio comparing the pulsatility of blood flow (often derived from Transcranial Doppler ultrasonography) against the pulsatility of the intracranial pressure waveform.
