## eRHC Calculator PRO Description
eRHC Calculator PRO is a hemodynamic calculator app for qualified healthcare professionals, used during right heart catheterization (RHC) procedures. Here's what it contains:

App Purpose
A clinical calculation and documentation tool for invasive hemodynamic measurements — specifically tied to the ALLAY-HF and ALLAY-HFrEF clinical studies.

Key Features
Patient data management — save/load/share patient records as JSON files, with patient ID, institution, weight/height (kg/lb, cm/in), DOB, and BSA calculation
Multi-stage calculator — timed hemodynamic measurements across stages (rest, exercise, etc.) with vitals, pressures, V-waves, CO via thermodilution or Fick method
Threshold system — configurable alert thresholds with rules (lower/upper bound, range, special PCWP rules)
Time synchronization — reference clock offset for procedure timing
Print/share results — formatted report output
Formula reference — all formulas listed (BSA, mPAP, PCWP, TPG, VO₂, CO, CI, PVR)
Formulas Implemented
BSA: Mosteller (general) and Du Bois (Fick-specific)
mPAP: (sPAP + 2×dPAP) / 3
PCWP from V-Wave: ((V-High − V-Low)/3) + V-Low
TPG: mPAP − PCWP
VO₂: Gender-specific regression equations (Dehmer et al.)
O₂ content: (Sat/100 × Hb × 1.36) + dissolved O₂
CO (Fick): VO₂ / (arteriovenous O₂ difference × 10)
CI: CO / BSA
PVR: (mPAP − PCWP) / CO (in Wood units)
