The oxygen provided by home and also portable concentrators deserve to be dispensed one of two ways, commonly referred to together either continuous Flow or Pulse circulation delivery. Both of this oxygen delivery methods carry out medical class oxygen directly to the user; however, the dosage is measured in different ways for each an approach of oxygen flow. Listed below we will comparison the 2 oxygen shipment methods and highlight the gadgets that feature them, this will aid you and also your physician determine what form of oxygen distribution is ideal suited for her lifestyle and also oxygen requirements.
You are watching: Is 2 liters of oxygen a lot
Continuous circulation oxygen flows without interruption native the cannula and only stops as soon as the concentrator is rotate off. These constant flow concentrators will provide the exact same amount of oxygen through the cannula nevertheless of the patients breathing patterns. This type of oxygen delivery allows the circulation rate to be measured at a continuous volume the LPM (liters every minute).
Pulse sheep oxygen concentrators are engineered come dispense oxygen as soon as the device senses inhalation. A “pulse” dose of oxygen, described as a “bolus”, is triggered and also released as soon as a patience inhales v a cannula. Pulse sheep oxygen machines have actually “settings” the indicates just how much oxygen is dispensed each minute. The amount (milliliters) that oxygen obtained by the patience (in a minute) will vary v the manufacturer, the setting, and the patient’s breathing (inhalation) rate. The dimension of the bolus of oxygen dispensed boosts when the settings are increased.
It need to be listed that when the manufacturers designed a setting of 2 on a pulse dose device to almost right 2 LPM on a consistent flow machine, these space NOT the same. Us recommend every patients considering a pulse dose machine both discuss the pros and also cons with their doctor and also test the unit because that efficacy come their particular needs.
Each model of portable oxygen concentrator has actually a “maximum oxygen output” which specifies the maximum amount of oxygen a given an equipment can deliver (regardless of setup or breath rate). Similar to a car’s horsepower, this is a good measure that a machine’s “capacity” to provide medical grade oxygen. The preferably oxygen output for each device is detailed in exhibit 1 below.

Exhibit 1: Portable oxygen concentrators (POC) and also their oxygen calculation in pulse sheep settings and ml/min.Note: The table is because that educational functions only. Oxygen calculation in pulse dose settings is not directly equivalent to continuous liter flow.
Pulse dose delivery was initially designed to enable for smaller sized machines and longer battery life. As such, plenty of smaller portable models just offer pulse sheep settings, when some bigger models feature dual-mode and offer both continuous flow and pulse delivery.
Your Oxygen Prescription
If you require oxygen therapy, your doctor will prescribe friend a provided oxygen circulation rate such together 2 liters every minute. One oxygen flow rate that 2 LPM means the patience will have 2 liters of oxygen flowing right into their nostrils end a duration of 1 minute. Oxygen prescriptions generally run native 1 liter every minute to 10 liters per minute v 70% the those patients gift prescribed 2 liters or less.
It is important to consult through your physician regarding your details oxygen requirements, both in ~ rest and also exertion. Identify the correct therapeutic dose because that both daytime and nighttime use will permit our Oxygen professionals to aid you in selecting the right equipment when renting or to buy your own concentrator. Us recommend patients discuss with their doctors their ability to use a pulse dose versus a consistent flow maker and the recommended setups on every machine.
If you room upgrading to a newer model of a concentrator, climate please examine with your physician whether her oxygen requirements have changed. We extremely suggest purchasing an oxygen concentrator i m sorry can supply oxygen higher than prescribed come accommodate the an altering needs.
Below is a an introduction of assorted home and also portable makers that attribute one or both that the distribution methods available.
