This slides contain detailed description of radiant warmer used in hospital setting, various modes , alarms, do's and don't of radiant warmer and nursing care management for the baby under radiant warmer
2. INTRODUCTION
O The radiant warmer (also called open care
system) was developed as an ‘open
incubator’ that ensures ready access to
the baby.
O The overhead quartz heating element
produces heat which is reflected by the
parabolic reflector on to the baby on the
bassinet.
3. O The quantity of heat produced is displayed
in the heater output display panel.
Temperature selection knobs select the
desired skin temperature.
O Radiant warmers provide intense source
of radiant heat energy. They also reduce
the conductive heat losses by providing a
warm microenvironment surrounding the
baby.
5. SERVO MODE
O Set temperature at 36.5 C, heater output will
adjust automatically to keep baby at set
temperature.
O If the baby temperature is below the set
temperature, the heater output will increase; if
the baby is at set temperature or higher the
heater output will become zero.
O Look for probe displacement when the baby in
servo mode every hour.
O Servo system is the preferred method of
running the open care system.
6. O In the servo mode, whenever the baby’s
temperature rises by more than 0.5°C
above the set temperature, a
visual/audible alarm is activated.
O Caregiver must pay attention to sort out
the fault.
O Often this occurs when the temperature
probe comes off the baby’s skin.
7. MANNUAL MODE
O The heat output from the quartz heating
rod could also be increased or decreased
manually.
O This is done by the heater output control
knobs. This is called the manual mode of
operation.
8.
9. O Temperature selection panel :Select
either set temperature or skin temperature
O Temperature selection knobs :Select a
desired set temperature
O Temperature display :Display
temperature as selected, either of the
baby’s skin (via skin probe) or the set
temperature
O Mode selector :Selects manual or servo
mode
O Alarm display for power failure, system
failure, skin probe failure
10. STEPS FOR USE OF
WARMER
1. Connect the unit to the mains. Switch
it on.
2. Once connected to mains, heater
output can be regulated by knob on
front panel. The output is displayed
as % or bars or bulbs
3. Select manual mode.
4. Select heater output to 100% for
sometime (20 minutes) to allow
quick pre-warming of the bassinet
covered with linen.
11. 4. Select servo mode.
5. Read the temperature on display
6. Select the desired set temperature of
baby as 36.5°C.
7. Place the baby on the bassinet.
12. 8.Connect skin probe to the baby’s
abdomen with sticking tape.
9. If the manual mode to be used, select the
desired heater output.
10. In the manual mode, record baby’s
axillary temperature at 30 minutes and then
2 hourly.
11. Respond to alarm immediately. Identify
the fault and rectify it.
13. 12. Ensure that baby’s head is
cover with cap and body with
clothes unless indicated to keep
naked.
13. Turn the baby frequently
14. Use of cling wrap
14. ALARMS ON SERVO RADIANT
WARMER
NO ALARMS IN MANUAL MODE
ALARM PROBLEM RESPONSE
“POWER ALARM” If the mains power
fails
Find alternative means for heating
if power cannot be fixed(KMC)
“SYSTEM
ALARM”
If there is an error
in the
electrical/circuit
Change WARMER, as it needs
repair
“SKIN PROBE
FAILURE ALARM”
If the temperature
probe sensor is not
connected properly
or if it is not
functioning
Try to re- connect the sensor
correctly. If does not work, change
it
15. “ SKIN
TEMPERATU
RE ALARM
HIGH OR
LOW”
This alarm operates
in servo mode only. It
sounds when the
patient temperature
differs from the SET
temperature by > 0.5
C
Change to manual mode with
maximum output if baby is having
low temperature and adjust the
temperature to try and normalize
the baby’s temperature. If baby is
having fever, shift to manual
mode and set appropriate heater
output. Check for signs of
infection
“HEATER
FAILURE”
Indicates heater is
not working
Change warmer, needs repair
16. APPLICATION OF SKIN
PROBE
Do’s Don”t
1.Prepare the skin using an
alcohol/spirit swab to
ensure good adhesion to
the skin.
2. Apply probe over the
right hypochondriac area in
the supine position.
3. Apply probe to the flank
in the prone position.
4. Check sensor probe
regularly so as to ensue that
it is in place. Ensure that
skin probe is free of
contact with bed.
1. Do not apply to
bruised skin.
2. Do not apply clear
plastic dressings over
probe.
3. Do not use
fingernails to remove
skin surface probes.
4. Do not reuse
disposable probes.
17. Use of cling wrap to decrease
insensible water losses
18. Potential pitfalls of servo-
controlled warmer
O In the event of probe getting displaced
from baby’s abdominal skin, overheating
of the baby will occur because the skin
probe depicts air temperature and heater
output keeps on increasing till probe
temperature matches control temperature.
O Also, repeated activation of alarm will
occur when baby develops fever. In this
situation, it is better to shift to manual
mode with least heater output.
19. Useful tips for use of radiant
warmers
O Don’t use the warmer in a cold room. It
works best when the environmental
temperature is above 20°C.
O Keeping the warmer where there is lot of
air currents reduces its efficiency.
O The warmer must be pre-warmed around
20 minutes before the arrival of the baby
or till the set temperature is reached with
less than 50% of total heater output.
20. O While using the manual mode in a warmer
without a temperature display, record the
baby’s temperature regularly, preferably 2
hourly.
O The manual mode is used for initial
preparation of bed for the baby or when
rapid warming of a severely hypothermic
baby has to be done. However, this may
be hazardous as babies may become
overheated. Except in the continuous
presence of a nurse who is watching the
skin temperature, it is preferable to use
the skin probe with the warmer on servo-
mode.
21. DISINFECTING RADIANT
WARMER
O When the equipment is in use, all
approachable external surfaces should be
cleaned daily with an antiseptic solution
like 2 % bacillocid or gluteraldehyde.
O Spirit or other organic solvents must not
be used to clean the glass side panels or
display panel.
O For disinfection of reusable probe,
isopropyl alcohol swab should be used.
22. O Every seventh day, after shifting the baby
to another cot, the used equipment should
be cleaned thoroughly, first by light
detergent solution and then by antiseptic
solution.
O All detachable assemblies, are to be
treated similarly.
