VTX-01 Engineering Overview
Live snapshot of the active cylinder configuration across all four models. Adjust the cylinder in the Cylinder Designer and every downstream calculation — cost, occupational exposure, and cold-temperature labeling — updates automatically.

Safety & Compliance Signals
VTX-01Cylinder Designer
Drag the sliders to size a DOT-39 non-refillable cylinder, modeled on the Catalina 2705. Dose = total minutes × flow rate sets the gas charge; the bottle geometry sets water capacity; fill pressure is derived (P = Vgas / Vwater), exactly as in the VTX Cylinder Design Calculator.

Cost of Goods (COGS)
Component build-up at pilot (~1k units) and commercial (~100k units/yr) volumes. Toggle the device architecture, edit any line, set an average selling price for gross margin, and multiply by annual volume for program cost.

Margin & Program Cost
Occupational Exposure — TWA vs REL/TLV
Single-zone, well-mixed room model with exponential ventilation clearance. Computes the exhaled-N₂O shift time-weighted average and compares it to the NIOSH REL (25 ppm) or ACGIH TLV-TWA (50 ppm). CORRECTED released N₂O = exhaled gas × N₂O fraction × (1 − patient uptake); the source workbook's "mod" tab dropped the N₂O-fraction term.

current dose settingsPhase Separation & Cold-Temperature Labeling
Predicts the condensation-onset ("layering") temperature for a 50/50 N₂O/O₂ mix at a given fill pressure, from the digitized Bracken (1970) dew-point curve. The output tracks your selected cylinder; use the Layering Explorer slider to sweep pressure freely and see how it shifts the onset temperature.

A trade-off read on the current cylinder configuration and its derived fill pressure, synthesized across price/COGS, design & manufacturability, occupational exposure, and cold-temperature phase behavior. Change the design in the Cylinder Designer and this updates.
