5 Best Free Online Oxygen Tank Duration Calculator Websites

Here is a list of the best free online Oxygen Tank Duration Calculator websites. Oxygen is the first thing all living beings need to survive. In some conditions, when there is a lack of oxygen or breathing difficulties, an oxygen tank is used. An oxygen tank is a portable container that stores and provides medical-grade oxygen. Oxygen tanks come in various sizes with different capacities. The size tells how many liters of oxygen a tank can hold. Then comes the tank pressure that implicates the current amount of oxygen in the tank.

To calculate tank duration, you need to know the tank capacity, tank pressure, and flow rate at which the oxygen is flowing output of the tank. A common flow rate for a patient is 1-5 liters per minute. Whereas a typical oxygen flow rate for a scuba diver is 1 to 2 liters per minute. This post covers 5 online calculators that can help you determine how long a specific oxygen tank will last. These calculators cover various tank sizes. You can pick a tank size and all the inputs to get the remaining time estimation.

My Favorite Online Oxygen Tank Duration Calculator

OxygenCalculator.com is my favorite website on this list to calculate oxygen tank duration. This website has a nice interface with visuals for the tanks. It covers 7 commonly used tank sizes with the option to add a custom tank capacity as well. Based on the input, it shows how long the supply will last in hours/days. It also shows how many tanks you would need per 24 hours for continuous oxygen supply. This can be handy for patients and healthcare professionals.

OxygenCalculator.com

OxygenCalculator.com is a free website that provides various oxygen-related calculators. You can use its Cylinder Duration Calculator to estimate how long the oxygen supply will last from a particular oxygen cylinder size. The calculator covers the commonly used cylinder sizes. You can simply pick a cylinder size and see the oxygen capacity of that size on the screen. You can also add a custom value for a specific amount of oxygen capacity. The calculator automatically loads the cylinder pressure value and asks you to provide the safe residual pressure value. You have to add the flow rate of the oxygen out of the cylinder. With that, the calculators show how long the respective oxygen supply will last. It shows the duration in hours that you can also toggle to days. This tool is designed for patients and thus also calculates how many similar-sized oxygen cylinders will be needed per 24 hours.

How to calculate oxygen tank duration on OxygenCalculator.com?

• Open this calculator in your browser using the link added below.
• Select the oxygen cylinder of choice or add the oxygen amount in liters at the top.
• Scroll down and fill in the Flow rate. Then verify the values of the Current Cylinder Pressure and Default Safe Residual Pressure.
• This gets you the oxygen cylinder duration on the right side of the screen.

Highlights:

• Cylinder Sizes: C, D, E, F, G, J, 50, and custom input.
• Input Parameters: Flow rate, Current Cylinder Pressure, and Default Safe Residual Pressure.
• Output: Duration (hours/days) and Cylinder needed per 24 hours.

OmniCalculator.com

OmniCalculator.com offers a free online Oxygen Tank Duration Calculator. This calculator can estimate how long an oxygen tank will last with a continuous flow rate. The calculator covers 9 different tank sizes that are commonly used. Each size also shows the respective capacity of the tank. This can help you pick the correct tank. Then you can add the flow rate at which the oxygen is flowing out of the tank and calculate the remaining time. This calculator does not let you add a custom capacity so you have to stick with the standard tank sizes.

How to calculate oxygen tank duration on OmniCalculator.com?

• Go to this calculator on OmniCalculator using the link provided below.
• Select the tank size at the top and enter the pressure in the tank.
• Then provide the flow rate in LPM to get the remaining time.

Highlights:

• Cylinder Sizes: C, D, E, F, M, G, H, J, K, and L.
• Input Parameters: Flow rate and Pressure in tank.
• Output: Remaining time.

RespCalc.com

RespCalc.com is a website that provides resources and tools for respiratory therapy students and professionals. The website has a blog post on Oxygen Tank Duration Calculation. It covers 5 commonly used oxygen tank sizes in medical. The web page covers the capacity of each type of tank. At the end, it has a “duration of flow” section where you get the formula. It has a simple calculator that works for D, E, F, M, G, and H/K tank sizes. You just have to select the tank size, add tank pressure, and flow rate. With that, the calculator determines the remaining time in minutes. Since this blog is for medical students and professionals, the calculator should have the option to set the default safe residual pressure for the tank for more accurate estimation.

RespiratoryCram.com

RespiratoryCram.com offers educational resources that focus on teaching respiratory therapy with the goal of passing the NBRC TMC-RRT and clinical simulation board exams. The website features an Oxygen Tank Duration Calculator that you can use to determine how long a tank will last at a continuous flow rate. This calculator works for D, E, H, and M tank sizes. You can pick the tank size from the list and then add the current tank pressure to mark the level of oxygen remaining in the tank. There is no option to set the safe residual pressure though. Then the calculator has a slider that you can use to set the flow rate from 0 to 15. As you add all the inputs, the calculator shows the remaining time.
