SECTION 2 • Description
2HOTLINE®3 Blood and Fluid Warmer | Operator’s Manual
SECTION 2
Description
The HOTLINE3 Warmer delivers blood and intravenous fluid at
normothermic temperatures by surrounding the sterile intravenous line
with a layer of warmed recirculating solution. An onboard recirculating
solution supply is heated to 37.5°C ± 0.5 and circulated through the outer
lumen of the HOTLINE3 Fluid Warming Set, which surrounds the
intravenous line.
The HOTLINE3 Warmer employs a safe, recirculating solution heating
system, inherently free of “hot spots,” to actively warm the patient line.
Electronic circuitry continuously monitors the recirculating solution
temperature. The primary temperature control circuit limits the
recirculating solution to 38°C maximum. In the unlikely event of a
malfunction of this circuit, a second “watchdog” circuit will visually and
audibly alarm and stop the recirculating solution pump if the temperature
reaches 39.2°C. Fluid in the HOTLINE3 Fluid Warming Set is never
exposed to any damaging or dangerous temperatures while the
HOTLINE3 Warmer is operating.
The recirculating solution temperature and visual alarms are indicated on
the Display Panel on the front of the HOTLINE3 Warmer. A green
Operating light illuminates on this panel when the HOTLINE3 Warmer
is set up and operating correctly.

SECTION 5 • Principle of Operation
12 HOTLINE®3 Blood and Fluid Warmer | Operator’s Manual
SECTION 5
Principle of Operation
HOTLINE3 Warmer delivers blood and intravenous fluid at
normothermic temperatures under routine, gravity flow rates.
Conventional fluid warming systems suffer from cool-down between the
warmer and the patient connection. HOTLINE3 Warmer overcomes this
problem by providing active warming of the patient line all the way to the
patient connection.
Active warming is achieved by surrounding the sterile intravenous line
with a layer of precisely controlled warm recirculating solution (a), thereby
protecting the patient line against exposure to cold and eliminating patient
line cool-down.
Infusate Delivery Temperatures
The following table shows the typical infusate delivery temperatures
at the patient end of an L-370 HOTLINE3Fluid Warming Set.
Note: The setpoint temperature of the recirculating solution is
