Common questions
About Fleckulator
What does Fleckulator calculate?
Fleckulator calculates oxygen cylinder duration and reserve margin for medical transport. It also provides U.S. hospital lookup, ground and air transport estimates, ventilator mode references, dive pressure and Nitrox calculations, ABG and acid-base interpretation, P/F ratio, predicted body weight, tidal-volume ranges, SAC, RMV, and breathing-gas duration.
How is oxygen cylinder duration calculated?
Usable oxygen equals starting pressure minus reserve pressure, multiplied by the cylinder factor. Estimated duration equals usable oxygen volume divided by total oxygen flow in liters per minute.
Does Fleckulator support air medical transport?
Yes. Choose rotor-wing or fixed-wing transport to estimate direct distance and flight time using an editable average speed. Enter launch, loading, ground-transfer, weather, and dispatch delays in the operational buffer.
Can I look up a U.S. hospital address?
Yes. Search the nationwide HIFLD hospital directory by hospital name, city, state, or ZIP code. Coverage reflects available federal and state source data and may not include every facility.
Which transport ventilators are included?
The reference covers common modes on ZOLL EMV and 731 Series, HAMILTON-T1, Vyaire LTV and LTV2, Philips Trilogy Evo, and Dräger Oxylog 3000 plus ventilators.
Can I calculate oxygen demand without a ventilator?
Yes. Choose nasal cannula, simple mask, partial rebreather, non-rebreather, Venturi mask, or a reservoir bag-valve mask. The selected source flow is used for cylinder demand, while the displayed FiO₂ is an estimate that varies with the patient and device.
Is this a clinical decision tool?
No. This is a planning aid only and is not a clinical or HIPAA-secure interface. Always verify the calculation, inspect for leaks, and clinically correlate.

How to calculate oxygen cylinder duration
Usable oxygen (L) = max(starting pressure − reserve pressure, 0) × cylinder factor (L/PSI). Duration (min) = usable oxygen ÷ total source oxygen flow (L/min). Use the cylinder’s verified factor and keep pressure units consistent.
Example: 1,800 PSI, a 200 PSI reserve and a 0.28 L/PSI factor provide 448 L. At 10 L/min, estimated duration above reserve is 44.8 minutes.
Patient flow and cylinder consumption
For a mask or cannula, the entered source oxygen flow drives cylinder demand. Delivered FiO₂ varies with device fit, breathing pattern and flow. A ventilator or air/oxygen blender may deliver mixed gas while drawing a different amount from the oxygen cylinder.
Use the relevant device consumption profile or verified measured source flow. FiO₂ alone does not determine oxygen consumption.
Transport time and oxygen reserve
Trip demand = total source oxygen flow × (travel time + operational buffer). Ground routing depends on available mapping services. Air estimates use direct distance and an editable speed, with operational delays entered separately.
For a 40-minute trip with a 10-minute buffer at 10 L/min, demand is 500 L. A 448 L usable supply leaves a 52 L shortfall.
