What is high flow oxygen delivery?
High flow oxygen therapy is a form of respiratory support used in the hospital where oxygen, often in conjunction with compressed air and humidification, is delivered to a patient at rates of flow higher than that delivered traditionally in oxygen therapy.
What is the difference between high and low flow oxygen delivery devices?
Low-flow systems often are more comfortable, but the ability to deliver a precise oxygen concentration in various respiratory breathing patterns is limited. A high-flow system can deliver very accurate oxygen concentrations, but is often uncomfortable and obtrusive.
What are the three types of oxygen delivery devices?
Oxygen delivery devices have historically been categorized into three basic types based on their design: low-flow, reservoir, and high-flow.
How many liters is low flow oxygen?
Low flow nasal cannulas can only deliver a nasal cannula flow rate of 4-6 liters of oxygen per minute. They don't provide humidified or heated oxygen. So, they often dry out the nasal passages.

Low-flow oxygen is a standard treatment option for anyone of these cardiopulmonary diseases: Chronic obstructive pulmonary disease (COPD) Pulmonary fibrosis. Emphysema.
Is being on 4 liters of oxygen a lot?
Rates of 4 liters/minute or greater are considered higher oxygen flow. As more scarring develops in the lungs, they become less efficient in delivering the necessary oxygen the body needs.
What is the normal flow rate of oxygen?
The normal flow rate of oxygen is usually six to 10 litres per minute and provides a concentration of oxygen between 40-60%. This is why they are often referred to as MC (medium concentration) masks, as 40%-60% is considered to be a medium concentration of oxygen.
What is dangerously low oxygen level?
If you're using an oximeter at home and your oxygen saturation level is 92% or lower, call your healthcare provider. If it's at 88% or lower, get to the nearest emergency room as soon as possible.
Is liquid oxygen better than a concentrator?
In conclusion, liquid-oxygen treatment was more expensive compared to concentrator treatment. However, treatment effects showed that liquid oxygen had a better impact on quality of life.
How long can you survive with low oxygen levels?
Most people will die within 10 minutes of total oxygen deprivation. Those in poor health often die much sooner. Some people may suffer other medical catastrophes, such as a heart attack, in response to oxygen deprivation.
What are the different types of oxygen therapy?
Oxygen can be delivered in three basic ways: via concentrator, compressed oxygen gas, and liquid oxygen. The least expensive and most efficient method to deliver oxygen therapy at home is via an oxygen concentrator. This device uses electricity to extract nitrogen from room air and delivers oxygen that is 95%-96% pure.
How many types of oxygen masks are there?
Regulations. Three main kinds of oxygen masks are used by pilots and crews who fly at high altitudes: continuous flow, diluter demand, and pressure demand.

What does it mean when oxygen blows by?
Blow-by oxygen is just that – it’s oxygen that blows by. This does not not apply oxygen directly, but rather indirectly by “blowing” on the patient’s face.
What is the concentration of oxygen in the atmosphere?
Oxygen occurs naturally in our atmosphere, at a concentration of 21%. Another term for oxygen concentration is FIO2, or fraction of inspired oxygen.
How often is oxygen used in the hospital?
Oxygen is used every day in and out of the hospital. In order to understand oxygen delivery devices and flow rates, we need to first understand a few basic principles and definitions.
What is low flow delivery?
Low flow delivery devices. These are oxygen devices that supply you with supplemental oxygen. But, the flow is not high enough to prevent you from inhaling room air. So, low flow basically means you will be inhaling a mixture of supplemental oxygen plus room air.
How much oxygen does a COPD device need?
These are low flow oxygen devices. Depending on the flow, they deliver anywhere from 22-44% FiO2. Most people with COPD only need 2-3 LPM. This delivers FiO2s of 28-32% respectively. This is usually all that's needed to maintain oxygen levels with stable COPD.
How much FiO2 can you inhale?
This allows you to inhale about 75% FiO2. Limitations. The FiO2 may vary depending on leaks in the system, Liter flow set, and your respiratory pattern. If they do not deliver enough oxygen to maintain adequate oxygen levels, a high flow oxygen device (see below) may be indicated.
What is the bag called when you exhale?
Supplemental oxygen comes up the tubing. While you are exhaling, this oxygen is stored in the bag. So, this bag is called a reservoir bag . It's a reservoir for oxygen. When you exhale, oxygen is stored in it.
What is a high flow nasal cannula?
High flow nasal cannula. These are fancy, and often weird looking, nasal cannulas. They allow us to deliver flows higher than 6LPM. They can deliver very high flows to you. What we set it at depends on what you can tolerate. It also depends on what your oxygen demands are. With these, we can deliver all the way up to 100% Fio2.
Does 6LPM decrease FiO2?
This may cause the FiO2 you are inhaling to decrease. Also, 6LPM is the maximum effective liter flow. So, if this is not enough to maintain an adequate SpO2, some other oxygen delivery device may be indicated.
Can you inhale room air with a rubber flap?
One of these holes is covered by a rubber flap. This flap acts as a one-way valve. This makes it so you can exhale through it, but you cannot inhale room air. Supplemental oxygen comes up the tubing.
What is Low-Flow Oxygen?
Low-flow delivery systems are specific devices that generally deliver oxygen at flow rates lower than patient’s ventilatory requirements. These are the devices that are used when consistency in fraction of inspired oxygen (FiO 2) delivery is not crucial. It is based on the patient’s anatomic reservoir and minute ventilation.
What is a High-Flow Oxygen?
High-flow oxygen delivery is a non-invasive respiratory support for critically ill patients to deliver very accurate oxygen concentration at flow rates that exceed patient’s respiratory requirements. It is usually defined as the administration of gas flow above 6-15 liters per minute.
Summary
Both high-flow and low-flow oxygen delivery systems are capable of administering a wide range of FiO 2. However, the terms high and low do not reflect the delivered FiO 2; in fact, it refers to the flow of gas delivered to the system.
