Precision Flow Interfaces & Disposable Patient Circuits


Vapotherm Family of Cannulae

Vapotherm Cannulae

The narrow prong Vapotherm nasal cannula design maximizes flush of expiratory gas and assures an open system.

Several sizes make it simple for the clinician to choose the best-fitting cannula that occludes less than 50% of the nares.

Disposable Patient Circuits

The Vapotherm Disposable Patient Circuit (DPC) is comprised of the disposable water path, vapor transfer cartridge, and delivery tube. DPCs are FDA cleared for 30-day single patient use, and are available in low flow (1-8 L/min) or high flow (5-40 L/min) versions.

Vapor Transfer Cartridge

Precision Flow DPC:

For use with the Precision Flow System.

Type Flow Range (L/min)
  • Precision Flow Disposable Patient Circuit Low
  • Precision Flow Disposable Patient Circuit High
  • 1-8
  • 5-40

Heliox Precision Flow DPC:


Disposable water path & delivery tube
For use with the Heliox Precision Flow System. The Precision Flow Heliox provides a non-invasive option for delivering heliox gas via nasal cannula, while providing optimal heat and humidification.

Vapotherm offers both High Flow And Low Flow versions of the Heliox DPC:

Type Flow Range (L/min)
  • Precision Flow Heliox Disposable Patient Circuit Low
  • Precision Flow Heliox Disposable Patient Circuit High
  • 1-8
  • 5-40

Nitric Oxide DPC:

For use with the Precision Flow System and Ikaria INOmax DSIR® System. This DPC allows clinicians to administer nitric oxide non-invasively via high flow nasal cannula. In the Precision Flow High Flow Therapy application, a special disposable patient circuit re-routes the gas to the INOmax injector module then back into the Precision Flow system.

Vapotherm offers both the High Flow and Low Flow versions of the Nitric Oxide DPC:

Type Flow Range (L/min)
  • Nitric Oxide Disposable Patient Circuit Low
  • Nitric Oxide Disposable Patient Circuit High
  • 1-8
  • 5-40
