Poultry House Air Quality & Respiratory Stress Index

Calculate Ammonia (NH3) & Carbon Dioxide (CO2) Respiratory Stress Index (RSI) and minimum ventilation rate adjustments.

🔬 Scientific Disclosure: Respiratory Stress Index (RSI) Formula

RSI = (NH3_ppm / 20) * 0.6 + (CO2_ppm / 3000) * 0.4

Ammonia exceeding 20 ppm paralyzes tracheal cilia in 48 hours, exposing broilers to E. coli and IBV.
