Section 2 Overview
The Precision Flow® is a system for high flow humidified respiratory therapy by nasal
cannula. It incorporates the Vapotherm core humidification technology with an electronic
blender and flow controller. The water and gas pathways are both incorporated into a
removable, disposable patient circuit.
Features
• The patient circuit is detachable and disposable: no
disinfection necessary
• Minimal downtime between patients: less than
five minutes to change disposables
• Built-in oxygen/air blender
• Built-in electronic flowmeters and controllers
• Self-testing and self-calibrating
• Internal battery backup maintains flow and
oxygen percentage for at least 15 minutes if AC
power is cut off. Battery recharges in 2 hrs.
• All internal sensors self-calibrating and self
monitoring
• Single button starts and stops the device
• Temperature, flow and oxygen percentage are
adjusted via a single setting control knob on
the front panel
• All values and alarms displayed in a single large
color-coded panel
• Flow range 1-40 lpm
• Oxygen percentage is fully adjustable from 21 to 100% when two 40 psi (276 kPa) gas
sources are used
• Inlet gas pressure range is 4-85 psi (28-586 kPa)
• Single gas operation- the Precision Flow
®
detects inlet gas pressure and blends flow
based on demand required and available supply. Supply pressure determines FiO
2
and
delivered flow; if demand exceeds supply an alarm sounds
• At low gas inlet pressures, maximum flow rate and oxygen percentage settings are
automatically reduced to match the inlet pressure
• Automatically senses cartridge type: maximum flow setting is automatically reduced if
low-flow cartridge is installed
• Warm-up time less than five minutes
• Sterile water is connected to the disposable water path using a standard
spike
• Universal power requirements allow use anywhere with only a change of power cord
• Scheduled maintenance: gas trap filters replaced at 6-month intervals, and oxygen
sensor replaced annually
