1. Caution If a malfunction occurs in the warming system discontinue use Notify your sales service center of the malfunction Service is only to be done by qualified personnel Caution The Model WT 5300A should not be operated in the presence of electromagnetic fields that are greater than 3 Volts meter This could cause shutdown of the Model WT 5300A by the fail safe function within the equipment Caution Ensure that the patient is dry or the warming system may be ineffective Introduction Intended Use The WarmTouch Model WT 5300A Patient warming system warming unit and blanket is intended for prevention and treatment of hypothermia For example with the surgical patient the patient in the preoperative holding area the pregnant woman who shivers during epidural anesthesia due to hypothermia or any patient who is uncomfortable anywhere in the cold critical care environment Manual Availability The most recent revision of this manual is available on the Internet at http www mallinckrodt com respiratory resp Serv_Supp ProductManuals html Background Information WT 5300A There are numerous ways of warming your patient from cotton blankets to water mattresses Research has shown that low temperatures surrounding the patient are a major factor contributing to hypothermia 2 The warming system covers the patient with warm air and actively transfers heat across the skin The result is to achieve normal thermia2. In creating this warm customized pocket of air around the hypothermic patient it is important to note that stagnant air even ifit is warm does not work as an effective heat transfer medium Stagnant air acts as an insulator preventing the boundary layer of molecules next to the skin surface from transferring heat Forced air warming causes warmed air molecules to flow over cooler skin surface It is this active flow of warmed molecules that acts as a heat transfer medium With the warming system air is warmed and delivered into a lightweight blanket CareOuilt or CareDrape Blanket that rests over or under the patient The CareQuilt and CareDrape blankets have many small perforations on the underside that allow air to exit the blanket and surround the patient 1 Morris RH Wilkey BR The Effects ofthe Ambient Temperature on Patient Temperature During Surgery Not Involving Body Cavities Anesthesiology 32 102 107 1970 2 Morris RH Influence of Ambient Temperature on Patient Temperature During Intra abdominal Surgery Annals of Surgery 173 230 233 1971 Introduction Safety Features The VVarming System is designed to give healthcare professionals more control over the patient s core body temperature There are several safety features of the warming system which make it safe and appropriate for such use Customized Warming Therapy Clinicians select temperature range setting at the onset of warming therapy to help ensu
