An IV fluid warmer is a piece of equipment medical professionals apply to pre-heat substances supplied to a patient. It is designed to maintain internal body temperature during the application of blood or additional types of fluids such as medications. This process decreases the chance of hypothermia in traumatized or individuals receiving surgery. Typical features sought by facilities or first response providers today include the ability to:
All fluid warming system features are equally important because they allow application to occur in a limited time environment and provide the consistency necessary for preventing secondary conditions like hypothermia.
Do Design Features Affect Fluid Warming System Capabilities?
The above listed fluid warming system characteristics have become fairly common among manufacturers of these devices; however, not all offer the same dependability or usage time frames. Equipment performance and quality is highly important to ensuring application is beneficial. Disposable models eliminate the risk of a bacterial infection because they do not use cartridges or require extensive cleaning. Professionals gain better results when the device can be ready for use in under a minute. Newer designs include sensors and additional mechanisms to prevent overheating. Battery power allows the equipment to be used in multiple settings including hospital environments, on first response vehicles, in combat atmospheres, and by specialists. An IV fluid warmer can be applied to prevent various problems resulting from rapid delivery of chilled substances.
Rapid introduction of cold fluids leads to further complications as a hypothermic condition worsens. These bodily changes occur as time progresses:
Internal body temperature decreases as a large quantity of cold fluid is delivered in a short period of time. A fluid warming system raises the temperature of a substance before it reaches the infusion site to counteract these complications. Patients can experience increased blood loss during surgery, have a lengthened recovery time, or suffer heart difficulties.
Ideal designs have the capability of delivering substances at low or high flow rates and can detect air for automatic shut off. Factors such as materials and the implemented heat exchange mechanism affect these abilities. A lower temperature substance naturally takes more time to heat. Fluids remaining in the exchanger for a longer period of time will have improved heating, meaning a device must accommodate for faster flow rates where this timeframe will not be present. The exchanger's total surface area affects generated heat with a larger surface offering increased warmth. Tubing loses warmth as the substance moves out of the exchanger into the infusion site. Length, amount of insulation, and flow rate have an impact on this performance factor. All must be taken into account when choosing or implementing an IV fluid warmer to be certain the patient receives appropriate temperature control for safer treatment.
