What is the device performance with intermittent (bolus) flows?

Intermittent (bolus) flow devices
In many instances, and especially for the sickest patients, emergency teams may apply the intermittent flow-inducing methods to accelerate the flow of blood/fluids to patients, control the volume (e.g. as typical for pediatric patients), or both. Popular intermittent flow methods include the “push-pull” method, hand pump, and LifeFlow® PLUS. All these methods generate rapid flows that are delivered intermittently; that is, a fast pulse of high flow followed by short period of no-flow (in which the device is reloaded with blood/fluid), and so on, until the transfusion ends.
The market gap:
Designed primarily to warm constant flows delivered by gravity, pressure bags, or electro-mechanical pumps, prevailing warmers cannot warm fluids/blood delivered intermittently, in rapid flows. In some cases, the cassette may even break due to the elevated pressure. Consequently, your sickest patients may receive cold blood/fluids.
What’s new?
From August 2021 onward, all new Warrior solutions include tightened performance specifications, designed to effectively warm rapid intermittent flows. The performance of the Warrior with constant flows remains top notch. Restrictions apply so please contact us for details.
