Description The EQUATOR® Convective Warming system consists of a high-flow convective warmer with hose-end temperature control, a convective warming blanket, and accessories. The convective warmer draws ambient-temperature air through a particulate air filter. The filtered air is warmed to a selected temperature. The warmed air enters the convective warming blanket through the hose and is distributed through delivery channels. Perforations on the patient side of the air delivery channels in the blanket gently disperse warm air over the patient. The convective warmer has three outlet temperature settings, which provide flexibility in patient treatment: 36°C, 40°C, and 44°C. These three temperature settings are servo-controlled by thermistors placed at the end of the hose where the hose connects to the convective warming blanket. A fourth temperature setting delivers ambient-temperature air. The temperature indicated on the control panel is the temperature of the air being delivered to the blanket at the end of the hose. A control thermistor adjusts the power applied to the heater to maintain the selected temperature. This enables the system to maintain the selected temperature under variations in ambient temperature. A safety thermistor provides a signal to a separate high-temperature comparison circuit. The safety thermistor activates and causes an alarm if the temperature exceeds the set point. The safety circuit provides an independent means of shutoff, which discontinues power to the heater and motor. This prevents patient exposure to excessive temperatures.

Snuggle Warm® Convective Warming Blankets The convective warming blanket consists of two layers of non-woven polypropylene fabric coated with a layer of polyethylene. The layers are bonded together to form a distribution network of air delivery channels. The warm air is distributed around the blanket through the delivery channels and exits the blanket through a specially designed series of perforations in the patient side of the blanket. The distribution of air is designed to minimize temperature differences throughout the blanket. Refer to Appendix A, Convective Warming Blanket Identification Chart, for the list of blankets available.

Only competent personnel knowledgeable in the safety procedures required for servicing live primary MAINS parts shall be allowed to open the enclosure. • Ensure that the convective warmer IV pole mounting clamp is properly tightened before each use. Failure to securely mount the convective warmer onto the I.V. pole may cause it to slide down the I.V. pole, and injure the patient or user. • Do not mount the convective warmer higher than 117cm (46") on the IV pole. For convenience, 117cm (46") is indicated by a black mark on the power cord. Mounting the convective warmer above 117cm (46") may result in instability of the pole and cause tipping that may injure the patient or user. • Do not change the air filter while the convective warmer is operating. Risk of thermal injury exists if the device is operating. • This device can only be used in conjunction with a Snuggle Warm® convective warming blanket. For the safe operation of this device, the user must follow all warnings, cautions, and instructions provided in the Instructions for Use supplied with the compatible convective warming blanket, in addition to this Operator's Manual. • Convective warming blankets can only be used in conjunction with the EQUATOR® convective warmer (EQ-5000) and the Snuggle Warm® convective warmer (SW-4000). For the safe operation of the blankets, the user must follow all warnings, cautions, and instructions provided in the Instructions for Use supplied with the compatible convective warmer, in addition to this Operator’s Manual. • Always start therapy on the lowest non-ambient temperature setting to prevent thermal injury. Increase the temperature setting, if required, using core body temperature and cutaneous response of skin in contact with the convective warming blanket as indicators. • To prevent thermal injury, do not use the highest temperature setting when treating patients who have decreased sensation, are nonsensate, or have poor perfusion. • Monitor patient's body core temperature, vital signs, and observe cutaneous response at regular intervals to prevent thermal injury. If erythema or instability in vital signs is evident, decrease the temperature setting or discontinue use of convective warming therapy. • To prevent thermal injury in hypotensive or hypoperfused patients, observe cutaneous response more frequently. Reduce the temperature setting or discontinue use of convective warming therapy if instability in vital signs or erythema occurs. • If the patient's nose or mouth is positioned against the convective warming blanket or the plastic drape, closely monitor the patient's breathing to prevent suffocation injury. continued

WARNINGS (continued) • Cover all open wounds in contact with the convective warming blanket to prevent airborne contamination. • The hose nozzle MUST be connected to a Snuggle Warm® convective warming blanket. Do not treat patients with the hose alone. Thermal injury may occur. • Use only one convective warmer and one hose. Use of multiple convective warmers in multiple inlet ports of the same convective warming blanket may cause damage to the blanket and thermal injury to the patient. • To prevent thermal injury, do not allow any of the patient's body parts to rest on the active hose inlet. • Do not place objects onto the convective warming blanket that will obstruct air flow. Items on the blanket can produce localized pressure on the patient’s skin, reducing cutaneous blood flow and causing thermal injury to the patient • For underbody blankets do not place objects, other than the patient’s body, onto the convective warming blanket that will obstruct air flow. Items on the blanket can produce localized pressure on the patient’s skin, reducing cutaneous blood flow and causing thermal injury to the patient. • For the SW-2013 Adult Underbody Convective Warming Blanket, always keep the arms at the patient’s side. Do not allow the patient’s arms to extend outside the blanket as they may obstruct airflow through the blanket. Airflow obstruction may result in insufficient patient warming and loss of therapy. • When replacing the hose, always disconnect the thermistor cable attached to the old hose. Be sure to attach the hose and thermistor cable from the new hose, prior to using the device. Never allow the use of two hoses where one hose is inserted in the air outlet of the device while the thermistor cable from another hose is connected to the device. Failure to replace the hose without replacing the associated thermistor cable may result in an uncontrolled temperature that may cause a serious burn to the patient. • Always place the perforated side of the convective warming blanket, the side with small holes, towards the patient. Failure to do so may result in thermal injury. • Do not use a convective warming blanket over transdermal medications as this may lead to increased drug delivery that may result in patient injury or death. • The convective warming blanket is for single-use only. Reusing the blanket may increase the risk of cross contamination. • Use with the EQUATOR® convective warmer (EQ-5000) and the Snuggle Warm® convective warmer (SW-4000). Using non-compatible convective warmers may cause damage to the convective warming blanket and thermal injury to the patient. continued
