How to Use This Calculator

Enter your prescribed flow rate (L/min) and daily usage in hours.
Select cylinder size (E, D, M, or H/K tank) and enter current cylinder pressure (psi).
Set pulse dose ratio if using a conserving regulator (typically 3:1 vs. continuous).
Review continuous and pulse-dose duration in hours, daily oxygen use in liters, and cylinders needed per day.
Use cylinders per day to plan delivery schedules and ensure adequate home oxygen supply.

How the result changes with Prescribed Flow (L/min)

Prescribed Flow (L/min): Continuous flow oxygen prescription in liters per minute.
Daily Usage (hours): Hours per day oxygen is used. 24 for continuous, typically 12-18 for exertional/nocturnal.
Cylinder Size (0=E, 1=D, 2=M, 3=H/K): Portable cylinder size. E-tank is most common portable; H/K is stationary backup.
Cylinder Pressure (psi): Full cylinder is ~2000-2200 psi.
Pulse Dose Ratio: Conservation ratio of pulse dose device (typically 2:1 to 6:1). Set to 1 for continuous flow.

Continuous Duration (hrs): Hours of oxygen at continuous flow from a full cylinder.
Pulse Dose Duration (hrs): Extended duration with a pulse dose conserving device.
Daily O2 Consumption (L): Total liters of oxygen consumed per day at continuous flow.
Cylinders/Day (Continuous): Number of cylinders needed per day at continuous flow.
Cylinders/Day (Pulse): Number of cylinders needed per day with pulse dose device.
Monthly Cylinder Cost ($): Estimated monthly cost for cylinder refills at continuous flow.
Monthly Concentrator Electric ($): Estimated monthly electricity cost for a home concentrator.

Identify Input Parameters
4 parameters
Prescribed Flow (L/min) = 2, Daily Usage (hours) = 16, Cylinder Size (0=E, 1=D, 2=M, 3=H/K) = 0, Cylinder Pressure (psi) = 2000 = 5 input(s) provided
Calculate Continuous Duration
Continuous Duration = continuousDurationMin / 60
4.7 = 4.7
Calculate Pulse Dose Duration
Pulse Dose Duration = pulseDurationMin / 60
14 = 14
Calculate Daily O2 Consumption
Daily O2 Consumption = prescribedFlow * hoursPerDay * 60
1920 = 1920
