or more information

We provide oxygen USP in oxygen tanks and pipeline systems equipment, so your facility is always prepared when your medical teams rely on oxygen gas as a medical intervention.

Medical applications

Oxygen USP gas is a colourless, odourless and tasteless respiratory assistance gas that sustains life. It is used as a medical treatment in chronic and acute cases:

  • To treat hypoxia or chronic obstructive pulmonary disease (COPD)
  • To supply ventilators during anaesthesia or resuscitation
  • As nebulisation for respiratory aerosol medications
  • In hyperbaric oxygen therapy
  • Against cluster headaches

Medical oxygen tanks

Air Liquide Healthcare offers oxygen cylinders with VIPRs (Valves with Integrated Pressure Regulator) designed for superior safety, efficiency and ease-of-use:

  • EZ-OX Plus™: our economic and original VIPR medical oxygen tank, with an analog gauge, fixed orifice flow selector, and 50psi power take-off port.
  • Intelli-OX™: the same VIPR fitted with an innovative digital gauge that accurately displays the time remaining based on flow rate and cylinder contents.

Bulk oxygen tanks

We offer reliable oxygen vessel systems, piping, and technical services based on your oxygen consumption (generally over 700m3), in compliance with Canada's building code requirements.

On-site gas production

We also specialize in providing safe, reliable, and compliant oxygen concentrators for those clients wishing to produce 93 percent oxygen USP on-site.
