Oxygen concentrators (OCs) provide a safe, reliable, and cost-effective primary hospital oxygen supply. This study found OCs reduced oxygen costs by 62% with no critical patient incidents reported.

Area of Science:

  • Medical Engineering
  • Healthcare Management
  • Respiratory Therapy

Background:

  • Harmonization efforts between Canadian Standards Association (CSA) and International Organization for Standardization (ISO) standards for medical gas supply.
  • Ten-year review of oxygen concentrator (OC) utilization in Canadian hospitals as a primary oxygen source.

Purpose of the Study:

  • Document the number of Canadian hospital sites using OCs.
  • Assess the impact of OCs on medical practice and patient care.
  • Analyze trends in oxygen costing and utilization at OC-equipped hospitals.

Main Methods:

  • Mail and telephone surveys followed by site visits to hospitals using OCs.
  • Detailed review of installation, service, operating costs, amortization, leasing, and patient safety records.

  • Analysis of clinical activity and operational data from participating hospitals.

    • Main Results:

    • Forty-eight of 52 Canadian hospitals participated, representing significant clinical activity and over 1 million hours of OC operation.
    • Oxygen concentrators reduced the unit cost of oxygen by 62% (P <.0001) with an 11.5% annual increase in consumption (P <.0001).
    • No patient care critical incidents related to OC use were reported.

    Conclusions:

    • CAN/CSA Z305.6-M92 compliant OC installations offer a safe and reliable primary hospital oxygen source.
    • OCs present a cost-efficient alternative to traditional medical oxygen supply systems.
    • The study supports the continued use and integration of OCs in Canadian hospitals.
