Oxygen Conserving Device (OCD) is a great option for patients on continuous oxygen therapy. Now, an important question is, what is the purpose of a pressure regulator on an oxygen​ tank? These devices play a crucial role in optimizing the utilization of oxygen by regulating its flow from the source, typically an oxygen cylinder or tank. Their primary function is to deliver oxygen only when the patient inhales, thereby minimizing wastage during exhalation. The conserver senses the patient's breathing pattern and releases a pulse of oxygen during the inhalation phase, reducing the amount of oxygen wasted during exhalation. This conserves oxygen and extends the duration of the oxygen supply. Factual information states that a person inhales 1:3 times and exhales 2:3 of the time. That means 2:3 of the oxygen gets wasted while the patient exhales. To control this wastage, conserving devices are helpful. OCDs greatly increase the time for which an oxygen reservoir can be used, i.e., it will last three times longer than the cylinder without the device.

Benefits of using an Oxygen Conserving Device

With OCDs, you can conserve a handsome amount of oxygen, so there will be less need for refills. Hence, buying an OCD is more economical and less wasteful. Buy oxygen-conserving devices from renowned brands with expertise in respiratory products at attractive prices on HPFY.

Types of Oxygen Conservers:

  1. Fixed Pulse OCDs

    These devices initiate when a person takes a breath. The fixed pulse concentrators release a fixed volume of oxygen when initiated and stop at a preset limit. The flow rate is high in the initial period, permitting the released volume to be delivered during the initial phase of inhalation. The volume of oxygen released varies by manufacturers and specific devices. These devices are intended to produce a rate of oxygen flow similar to continuous flow. The rate of flow varies from 5 ml to 22 ml per setting per breath.

  2. Demand-Pulse OCDs

    These devices are also breath-initiated, but post-delivery of the initial volume of oxygen, these OCDs continue to deliver a fixed rate of oxygen, i.e., 2 liters/minute, until exhalation, depending on the manufacturer. Some devices have a diminishing flow rate until the valve closes, stopping the flow completely. The oxygen delivered in the last one-third of the breath is considered to be wasted as it falls into the anatomical dead space of the breath.

O2 Conserving Devices or Flow control regulators reduce the pressure. They are designed to regulate or lower oxygen pressure from an oxygen cylinder to a level the patient can safely use.

What Are Oxygen Regulators?

Unlike conserving devices for oxygen, O2 regulators have flow control valves that help regulate the flow of oxygen depending on the dosage of the user. It is a device used to control and adjust the flow of oxygen from an oxygen source, such as a cylinder or concentrator, to a desired flow rate. It ensures a constant flow of oxygen at the prescribed rate, typically measured in liters per minute (LPM). Oxygen regulators are equipped with pressure gauges to monitor and maintain the appropriate oxygen pressure level. Oxygen-conserving devices work automatically to alter the flow, whereas regulators need to be physically calibrated to set the flow of oxygen. This makes oxygen-conserving regulators cheaper than oxygen-conserving devices.

Benefits of Oxygen Regulators

Oxygen Conserver vs Regulator

Key Differences:

  1. Function: An O2-conserving device is primarily designed to conserve oxygen by delivering oxygen only during the inhalation phase, while an oxygen regulator controls and maintains a constant flow rate of oxygen.
  2. Oxygen Conservation: The oxygen-conserving device is specifically designed to conserve oxygen by reducing wastage during exhalation, thereby extending the duration of the oxygen supply. The oxygen regulator does not have oxygen-conserving capabilities.
  3. Delivery Method: The O2 conserver delivers oxygen in a pulsed manner, synchronized with the patient's inhalation. It delivers a continuous flow of oxygen at a constant rate.
  4. Usage: Oxygen conservers are commonly used in portable oxygen systems to enhance portability and extend the life of oxygen cylinders. Oxygen regulators are used in both portable and stationary oxygen systems to control the flow rate of oxygen to the patient.

Frequently asked questions

An oxygen conserving device controls the flow of oxygen from the source to the patient thus making oxygen therapy more efficient. Only when the patient inhales is the oxygen released through the device, delivering a “pulse” of oxygen. This makes the patient more mobile and also conserves oxygen thus increasing the patient’s oxygen-use period.

An oxygen regulator controls the free flow of oxygen from the cylinder to the patient. It is also referred to as a pressure regulator. A flow meter attached to the oxygen tank controls the speed of oxygen delivery from the cylinder. The doctor or caregiver may set the flow speed from 1-25 liters (LPM) per minute depending on the patient’s need of oxygen.

An oxygen flow meter is a device that is used to measure the flow of oxygen from the cylinder to the patient. It is usually attached to the oxygen cylinder but sometimes you may find it as a standalone device.

An oxygen flow meter is important during oxygen therapy because it provides a quantitative measurement of the gas flow and helps the caregiver monitor the therapy. An advantage of this device is in case of a blockage in the oxygen supply tubing. In such a case the doctor or caregiver is immediately alerted if there is an interruption in the supply.
