Precision Medical Easy Guage Regulator

PulseDose LT Compact Oxygen Regulator

PulseDose Oxygen Conserving Devices deliver a flow of oxygen on the leading edge of inspiration. As an oxygen conserver, the PulseDose is more efficient than continuous flow, since it delivers consistent high flow delivery when the patient needs it most. Brand new, the PD1000 PulseDose LT Compact is DeVilbiss's lightest and most compact model.

Since oxygen waste is minimized, patients will be able to extend cylinder life dramatically. Ambulatory therapy will enable them to pursue the benefits of a more active lifestyle. Patients often report an improved sense of taste and smell, and decreased drying of nasal passages with PulseDose systems. They are more likely to wear their oxygen constantly, resulting in better compliance with their prescribed oxygen therapy.

  • FEATURES

    • True 3:1 savings
    • Very light weight, only 16.3 oz! - Three year warranty
    • Audible alarms sound (low 02 and no breath taken)
    • Field-serviceable: speeds return of unit to use
    • Easy to set-up, use and maintain
    • Adjustable continuous flow setting does not require batteries

Frequently Asked Questions About Regulators

LEARN MORE

  • What is the difference between an oxygen regulator and a vacuum regulator?

    An oxygen regulator reduces and controls gas pressure or flow from a compatible oxygen source, depending on its design. A vacuum regulator controls suction from a medical vacuum system. These devices serve different functions and are not interchangeable. Susquehanna Micro supplies both oxygen regulators and vacuum/suction regulators for healthcare equipment applications.

  • What oxygen regulator models does Susquehanna Micro carry?

    Susquehanna Micro offers Precision Medical oxygen regulators, including Easy Dial, Easy Gauge, and PulseDose LT models. Available products provide different adjustment methods, flow ranges, and connection configurations. Our team can help healthcare equipment buyers compare the specifications of available models.

  • What is the difference between a dial oxygen regulator and a gauge-style regulator?

    A dial regulator uses selectable flow settings, while a gauge-style regulator provides a visual flow indication through its gauge design. Precision Medical's Easy Dial and Easy Gauge regulators offer different approaches to flow adjustment and monitoring. The best option depends on the equipment requirements and user preferences.

  • What is a continuous-intermittent vacuum regulator?

    A continuous-intermittent vacuum regulator is designed to provide selectable suction modes. The Precision Medical models listed by Susquehanna Micro include regulated suction, off, and intermittent operation. These devices should be selected and operated according to the manufacturer's specifications and the intended clinical application.

  • What should I verify before ordering a medical oxygen or suction regulator?

    Confirm the intended gas or vacuum application, connection type, required pressure or flow range, and compatibility with the existing equipment. For oxygen regulators, cylinder connection styles such as CGA 870 and CGA 540 may be relevant. For vacuum regulators, facilities should also verify the required suction range and operating modes. Susquehanna Micro can help customers review available configurations before ordering.
