Portable Oxygen Concentrator Guide

Portable Oxygen Concentrator Guide

This Bradshaw Oxygen guide helps customers compare portable oxygen concentrators by oxygen delivery type, battery option, travel use, and prescription requirements. It is also written as a product knowledge base for Bradshaw AI so answers can be grounded in Bradshaw Oxygen product pages.

Important Medical and Prescription Notice

Oxygen concentrators are prescription devices when used for medical oxygen. Bradshaw Oxygen does not diagnose, prescribe, or determine oxygen settings. Customers using oxygen for medical purposes should follow their licensed medical provider's prescription and instructions. If a customer is unsure whether pulse dose or continuous flow is appropriate, they should confirm with their licensed medical provider before purchase.

Portable Concentrators Are Not for Glassblowing or Hyperbaric Oxygen Supply

Portable oxygen concentrators are designed for mobility and travel oxygen support. They are not intended for lampworking, glassblowing, hyperbaric chamber oxygen supply, or high-demand industrial oxygen use. Customers needing oxygen for a torch, chamber, lab, animal hospital, university, or industrial application should contact Bradshaw Oxygen for equipment guidance.

Pulse Dose vs Continuous Flow

Most portable concentrators provide pulse dose oxygen. Pulse dose settings are not the same as continuous LPM flow. Pulse dose delivers oxygen in response to inhalation and is commonly used for portable mobility. Continuous flow provides a steady flow measured in LPM. Customers prescribed continuous flow should not assume a pulse dose portable will meet their needs.
