Different oxygen delivery systems

Low-flow systems like the trusty nasal cannula deliver oxygen at a rate that is less than the amount of air that the patient can inhale or exhale in one minute called minute ventilation. There is a wide variety of devices available to provide oxygen support.

Continuous flow dose delivery and pulse mode delivery.

Different oxygen delivery systems. Before we get into the different types of oxygen delivery systems we need to go over a few key terms. First of all you will hear systems referred to as low-flow and high-flow. Low-flow systems like the trusty nasal cannula deliver oxygen at a rate that is less than the amount of air that the patient can inhale or exhale in one minute called minute ventilation.

Generally there are two types of oxygen delivery in oxygen concentrators. Continuous flow dose delivery and pulse mode delivery. Continuous flow dose delivery supplies a constant steady and reliable oxygen flow based on the setting number in Lmin 1 while pulse mode delivery delivers a pulsed bolus of oxygen when the user begins to take a breath.

Furthermore what are the different oxygen delivery systems. Oxygen delivery devices have historically been categorized into three basic types based on their design. Low-flow reservoir and high-flow.

Supplemental Oxygen Low Flow Systems maskface tent non-rebreather mask Provides relatively stable FiO2 levels as long as respiratory rate and pattern are stable Can deliver high FiO2but actual amount will vary from breath to breath Examples include nasal cannulasimple face. Concentration of oxygen is 40 to 60 at flow rates of 5 to 8 Lmin. Partial Rebreather Face Mask Oxygen reservoir bag attached Concentration of oxygen is 40 to 60 at flow rates of 6 to 10 Lmin.

Concentration of oxygen is 95 to 100 at flow rates of 10 to 15 Lmin. Oxygen use has extended from inpatient to outpatient settings for patients with chronic pulmonary diseases and complications of hypoxaemia. This article presents an overview of oxygen devices oxygen concentrators compressed gas cylinders and liquid oxygen and delivery systems high- and low-flow.

Different colours deliver different rates. The correct flow rate to use with each colour it is shown on mask along with the percentage of oxygen delivered. BLUE 2-4Lmin 24 O2.

WHITE 4-6Lmin 28 O2. YELLOW 8-10Lmin 35 O2. RED 10-12Lmin 40 O2.

GREEN 12-15Lmin 60 O2. The least invasive method of oxygen delivery is going to be the basic nasal cannula. Now the nasal cannula is going to deliver just a very minimal amount more of FiO2 than basic atmospheric air.

So we know that FiO2 in the basic atmospheric air if you go outside. At each different oxygen flow the subject breathed normally for five minutes. Using the oxygen sampling system three gas samples 60 mL each were withdrawn from the pharynx during inspiration and directed to the oxygen analyzer.

The average FiO2 delivered was recorded for each one of the oxygen flows administered with the different systems. High-Flow Nasal Cannula HFNC is a newer method of delivering a high flow and FIO2 of oxygen in patients who have higher oxygen requirements. COVID patients tend to do well on these devices but it can be used for all sorts of respiratory distress.

These range from simple nasal cannulas ones allowing for monitoring of expired CO2 to high-flow nasal oxygen delivery systems HFNO systems actually deliver a. Oxygen Delivery Systems LOW FLOW OXYGEN DEVICES HIGH FLOW OXYGEN DEVICES Cannot deliver constant FiO 2 Maintain constant FiO 2 Flow 6 - 8 Lmin Delivering O 2 at very high flow Mixture of oxygen room air Flow usually 4 times the actual Minute volume FiO 2 varies with tidal volume-Shallow breathing less entrainment of room air high FiO 2. Different industries including health systems use oxygen in regular basis.

Oxygen in the market is available for industrial and medical use. Medical-use oxygen is very different from industrial oxygen in purity and quality. Thus industrial and medical use are not interchangeable.

There are many types of Oxygen Delivery Systems available and here are the most popular ones. Compressed Oxygen Therapy oxygen therapy delivered through oxygen tanks. There are H tanks E tanks and D tanks available.

The D E types of oxygen. All oxygen delivery systems including tubing and gas connection and medical order are to be checked by TWO staff members and the status documented at EVERY SHIFT change. This includes correct tubing is connected to the correct flow meter either oxygen or air and the set flow is correct.

The delivery system needs to be checked minimum one hourly. Oxygen therapy can be delivered using a low flow or high flow system. All high flow systems require humidification.

The type of humidification device selected will depend on the oxygen delivery system in use and the patients requirements. The humidifier should always be placed at. Types of Oxygen Delivery Systems.

Masks Nasal cannula and Tubing. Choosing the right oxygen therapy device can significantly improve the convenience of oxygen therapy and make it easier to travel and stay active. This oxygen delivery devices and flow rates chart shows how many oxygen percentages delivered according to the different flow rates.

The percentage of oxygen inspired depends on the flow rate and the delivery device. With oxygen delivery methods its really about how much FIO2 can be delivered not really the flow rate in liters. Fraction of Inspired Oxygen FiO2.

Method FIO2 and Flow Rates Indications Comments First-Line Options Standard nasal cannula The NC can deliver an inspiratory oxygen fraction FIO2 of 24-40 at supply flows ranging. Theyre not what you think. Indications for oxygen use Low ambient O2 Hypoxemia Suspected hypoxemia Increased work-of-breathing Flaring Tachypnea Increased myocardial work Acute head injury O2 delivery systems High-flow Venti-masks air entrainment masks Mechanical aerosol systems High-flow humidifier systems Low-flow.

The mechanism for Oxygen delivery to the patient Oxygen Monitoring systems. Different aspects like health facility available infrastructure capacity supply chain cost etc. Are considered to determine the oxygen system especially the Oxygen Source.

Oxygen Delivery Systems. There is a wide variety of devices available to provide oxygen support. Delivery systems are classified as low-flow or high-flow equipment which provide an uncontrolled or controlled amount of supplemental oxygen to the patient British Thoracic Society 2008.
