Failure to properly follow warnings, cautions, and instructions could result in death or serious injury to the patient.
! WARNING ! Messages that are headed by "! WARNING !" indicate information or procedures that if not followed correctly can cause improper results, damage to the equipment, injury to personnel, or patient death. Messages that are headed by "CAUTION:" indicate information or procedures that if not followed correctly can cause improper results and damage to the equipment. Messages that are headed by "NOTE:" indicate information or procedures that if not followed correctly can cause improper results.
Purpose The Level 1® H-1000 fluid warmer has been designed for safe, rapid in-line warming of I.V. fluids as they are administered to patients. Disposable sets designed for warming at various infusion rates are available. Blood and I.V. solutions may be infused through the Level 1® I.V. Sets, and will be delivered near 40 °C. High flow capacity, warm fluid delivery, simple operation, and continuous on-board safety systems make the H-1000 the ideal choice for all procedures requiring routine to rapid infusion of normothermic fluids. Typical uses of the system include blood and solution warming during elective surgery, in the I.C.U., the Emergency Room and in Trauma.
Concept The H-1000 fluid warmer consists of a reusable hardware device and a single-use disposable set. Similar to extracorporeal warming technology found in the heart room, warmed water is rapidly circulated through a disposable anodized aluminum tube to warm fluids as they are delivered to the patient. The use of a thermal conductor, rapid warm water circulation, and counter-current flow all contribute to the high warming capacity of the H-1000.

System features Filter with Gas Vent Level 1® D-Series Disposable Sets employ a unique "hands-off" Gas Vent which vents micro-bubbles of gas that are always released from fluids as they are warmed. In many other warming systems, these micro-bubbles are actually delivered to the patient along with the warmed fluids. The Filter with Gas Vent assembly in the I.V. Sets contains a 170-micron screen filter to trap macro-aggregates found in blood products. This filter has luer-lock connections and

can be easily changed without patient disconnection or repriming of the entire disposable set. The Filter with Gas Vent should be changed every three hours or when the filter becomes clogged, whichever comes first. Temperature control The H-1000 employs a safe circulating water heating system, inherently free of any "hot spots." The primary temperature control circuit sets the circulating water bath to a temperature of approximately 42 °C for efficient heat exchange and maximum fluid warming. Flanking I.V. Pole Brackets The sturdy design of the H-1000 offers a compact, custom I.V. pole mount set up. This versatile workstation features flanking side poles for Level 1® pressure infusers, syringe pumps or infusion pumps.

Accessories: H-1025 Pressure Infusers The H-1000 is equipped with an onboard compressor that is used to operate two Level 1® pressure infusion chambers (H-2’s). Pressure Infusion chambers are sold separately as an accessory to the H-1000. The H-1000 combined with two pressure infusion chambers is referred to as the H-1025. Pressure Infusers are not required to operate the H-1000, but are a valuable accessory to complete this total fluid management system. H-1025 pressure infusers provide controlled, convenient pressurization of I.V. blood and fluid bags for rapid administration of fluids. These automated pressure chambers quickly reach and hold a preset pressure of 300 mmHg for high speed fluid delivery not possible with manually pumped pressure cuffs. The factory set 300 mmHg pressure is constant and not adjustable. At 300 mmHG pressure, flow rates may be altered by adjusting the roller clamp on the Level 1® D-series disposable I.V. fluid warming set. With the H-1025 infusion chambers, pressure can be applied or released with the throw of a switch. Empty I.V. fluid bags can be de-pressurized, replaced and repressurized in seconds. Each pressure infuser contains an expansion bladder to accommodate either a 500 ml bag or a 1000 ml bag. And a safety relief valve is also contained in each chamber to help prevent over-pressurizing fluid bags. If you have purchased a pair of pressure infusion chambers, please refer to the following pressure infuser set up instructions for proper installation. Packaging for each pair of H-1025 pressure infusers should contain the following items: Contents

Trouble Shooting PROBLEM
THINGS TO CHECK
No Power
Make sure that the unit is plugged in and the power switch is ON. Is it plugged into correct circuit?
Check Disposables Alarm
Make sure the heat exchanger and filter are properly installed and the top (#2) socket is down. If the top (#2) socket is not properly seated, the yellow light next to it will illuminate.
Add Water Alarm
Make sure that the water tank is filled above the minimum mark level. Fill or top off the tank with DISTILLED water only.
Water Over Temperature Alarm
Turn off the power switch to clear the alarm. Turn on the power switch again. If the unit continues to alarm, remove it from service for repair.
Hot cabinet
Make sure that the air inlet on the bottom of the unit is not blocked or clogged with dust.
Difficult to Install Heat Exchanger
Lubricate the O-Rings in heat exchanger (#1) and (#2) sockets with silicone. Order Part # 80-04-002 to replace O-Rings.
15
Trouble Shooting Slow Flow Rates Many factors which are insignificant in low fluid administration are restrictors of higher flow infusion. If you encounter flow restriction with any Level 1® Fluid Warmer, CHECK EACH OF THESE POSSIBLE CAUSES. OLD BLOOD Stored blood begins to develop particulate within 5 to 7 days. This may partially block fluid pathways, impeding flow. FULLY SPIKED BAG Bag port membranes may only be split, not completely pierced. BAG PORT FILTER (if used) 40 micron to 80 micron filters used between the blood bag and the bag spike of the Disposable set may restrict flow because: 1. Cold, viscous blood does not flow well through small pore filters. 2. As they are directly connected to the source of particulate with no prefiltering, they clog quickly. 3. They may trap air which can block filter media surface area. CLAMPS PARTLY ENGAGED Check to be sure all clamps are fully open. TUBE SET Leaving clamps engaged for extended periods of time when the Disposable Set is not in use (such as pre-set-up) will cause the tubing to take a SET in the clamped position. TUBE KINK Be sure no tube kinks are present anywhere in the set, especially in the Y-set when a pressure cuff is employed and the IV Pole is used in a lowered position. TRAPPED AIR IN FILTER As noted in the Priming instructions, remove the Filter from the holder and tap against the Cabinet to dislodge air bubbles and allow them to vent out. CLOGGED FILTER If good quality blood is used, this filter should never cause flow restriction. In the event of a clogged filter, this component may be changed. If frequent clogging is encountered, discuss the QUALITY of the blood being used with your Blood Bank EXTENSION LINES Use only extension lines with a bore of .130" (3.3 mm) or larger, equipped with large bore fittings, such as Level 1® Part No’s. X-36 or Y-30. STOPCOCK OR Y ADAPTER Any fittings attached to the male luer-lock at the end of the Patient Line should have large bores. If their bores are smaller than the male luer-lock bore, they are restrictors. NEEDLE or CATHETER If possible, use a minimum 18 Gauge needle or 16 French catheter. Smaller sizes will reduce flow.
16
Testing The H-1000 is equipped with disposable set sensing interlocks. To operate the device and perform testing operations a Level 1® non-sterile, not for patient use D-series disposable set with heat exchanger and filter assembly must be in place.
! WARNING ! Do not attempt to defeat the disposable sensing interlocks or try to operate the H-1000 without a disposable in place. Water may spill from the unit if the interlocks are defeated. CAUTION: Prior to placing the H-1000 into service, the device must be tested by Smiths Medical technical personnel, an authorized distributor of Smiths Medical or a trained biomedical engineer. Periodic testing and maintenance should be performed by a biomedical engineer or trained personnel. NOTE: Refer to Maintenance and Testing Log section of this manual for safety testing frequencies and intervals. Add Water Alarm The H-1000 is equipped with a float switch which senses the water level in the onboard reservoir. When the water level is too low, a yellow indicator on the display panel illuminates and an audible alarm sounds. In the alarm condition the pump will not circulate water. With a test disposable set in place, the ADD WATER alarm may be tested by turning the drain valve on the bottom of the unit 90 degrees clockwise and allowing water to drain out into a container. Drain until the water level falls below the minimum mark on the water tank. Check Disposables Alarm Three interlocks sense a properly installed heat exchanger. If a heat exchanger is not in place and the power switch is ON, a yellow indicator will illuminate and an audible alarm will sound. With the unit running, the interlocks may be tested one at a time by following these simple steps. 1. Top Heat Exchanger Socket Slide up slowly, two yellow indicators will illuminate and the audible alarm will sound. 2. Heat exchanger interlock Gently pull on the middle of the heat exchanger, one yellow indicator will illuminate and the audible alarm will sound. 3. Filter holder interlock Remove the Filter with Gas Vent, one yellow indicator will illuminate and the audible alarm will sound.
17
Water Over Temperature Alarm Press and hold the Water Over Temperature alarm test button on the power and test panel on the front of the unit. The display will jump to 45 °C (as long as the button is pressed on), and the red over temperature indicator will illuminate and the audible alarm will start to pulse. NOTE: The Water Over Temperature Alarm test button actually tests the over temperature circuitry of the system, not just the visible red display indicator and the audible alarm. NOTE: Pressing the Water Over Temperature test button or the Alarm test button will disable the H-1000 even after the buttons have been released. The unit must be shut off and then re-started to clear the alarm condition. Alarm Testing The audible alarm and all indicator lights may be tested by pressing the Alarm test button on the power and test panel on the front of the cabinet. NOTE: Pressing the Alarm test button or the Water Over Temperature test button will disable the H-1000 even after the buttons have been released. The unit must be shut off and then re-started to clear the alarm condition. Performance Testing Periodic testing of the overall operating efficiency of the H-1000 can be accomplished in one of two simple ways: 1. COLD START TEST NOTE: This performance test requires a non-sterile, not for patient use Level 1® D-series disposable set to be installed properly on the H-1000. Store the H-1000 unit in a room where the room temperature is approximately 21 °C (70 °F). With a non-sterile D-series disposable set in place, note the time, and then turn the power switch ON. The green "OPERATING" indicator will illuminate. Rapidly rising numbers will appear on the circulating water bath temperature display. A 41 °C temperature reading will appear in approximately 3 to 7 minutes on an efficiently operating unit. NOTE: If the H-1000 does not pass the cold start test, it should be returned to Smiths Medical or an authorized distributor of Smiths Medical for service. Do not attempt to change the calibration settings. 2. THERMAL CALIBRATION WELL (TCW) Available from Smiths Medical, a TCW may also be used to test performance and confirm proper calibration of the water bath temperature.
18
NOTE: Use of the TCW requires a digital thermometer NIST traceable and accurate to within 0.1 °C. Required probe size: 0.099" OD maximum (0.25 cm) 0.50" - 1.50" long (1.27 - 3.81cm) A short procedure to verify the displayed circulating water bath temperature is as follows: 1. Install TCW in machine in normal heat exchanger position (Socket #s 1 & 2) and install a test filter assembly at holder (#3). 2. Turn the machine on and allow to warm up for 20 minutes. Insert thermometer probe fully into well and allow display to stabilize. Compare temperatures. 3. The H-1000 display will be within 0.3 °C of the thermometer display on a correctly calibrated unit. Examples: a. If the thermometer reads 41.4 °C and the H-1000 is within the range of 41.1 °C - 41.7 °C, performance is acceptable. b. If the thermometer reads 42.0 °C and the H-1000 is within the range of 41.7 °C - 42.3 °C, performance is acceptable. NOTE: If the system does not conform to within these specifications, it should be returned to Smiths Medical or an authorized distributor of Smiths Medical for service. 3. D-SERIES CALIBRATION THERMOMETER (”TempCheck”) Available from Smiths Medical, the TempCheck device may also be used to test performance and confirm proper calibration of the water bath temperature. The D-series TempCheck device accurately verifies the temperature of the H-1000 circulating water bath. It plugs into the auxiliary outlet on the bottom of the H-1000 and does not require a separate NIST traceable digital thermometer for operation. Earth leakage The H-1000 must be tested according to IEC 601-1 clause 19. Earth leakage current testing should be performed with the immersion heater circuit in the full ON condition. In order to be sure the heater circuit is in a full ON condition, testing should be performed on units which have been allowed to stand at room temperature, and have room temperature water in the water reservoir before the unit is turned ON. The H-1000 warms up quickly, test readings must be taken within 1 minute of startup. A steel stud is positioned on the back of the unit for earth leakage testing. Units not meeting this standard should be returned to Smiths Medical or an authorized distributor of Smiths Medical for service.
