2. RADIANT WARMERS
(OPEN CARE SYSTEM)
• Intense source of radiant heat
energy
• Over head quartz heating
element produces infra red
radiation energy
• Reduces conductive heat loss
by providing warm
microenvironment
3. Skin servo control
• If the temperature probe is placed over brown
fat deposit areas, the probe will be reading a
core body temperature and not a skin
temperature.
• Core temperature is higher than the skin
temp., the warming device will cool the
environment.
• The infant will then need to burn fat and
calories to stay warm
4. RADIANT WARMER :
• 2 modes-servo and manual.
• SERVO MODE :
• Commonly used
• Microprocessor automatically increase
heater output if skin temperature of
infant is less than set temperature.
• Alarm is activated for every 0.5oc rise in
skin temperature.
• MANUAL MODE :
• Heater output is modified manually
• Used for initial preparation of bed for
the baby or for rapid warming
• Axillary temperature has to be
measured every 30 min till desired
temperature is reached and then every
2 hrly.
• More chances of over heating
5. RADIANT WARMER :
• Warmer to be prewarmed in
manual mode for 20 minutes
before use
• Use cling wrap to decrease
insensibile heat loss esp for
VLBW infants
6. Skin temperature Probes
• Do Not lay infant on skin probe
• Do not place over:
– Bony prominences
– Areas of brown fat deposits
– Poorly vascular areas
– Excoriated areas
– Keep probe exposed to heat source
– Keep probe securely attached
7. RADIANT WARMER
ADVANTAGES :
- Open care system / easy accessibility
- Better monitoring of baby
- Lesser risk of infection compared to closed
incubators
- Can be used as resuscitation trolley in labor rooms
DISADVANTAGES :
- More insensible water loss
- Not uniform heating
- More risk of hypothermia / hyperthermia
8. INCUBATORS
• Closed system with heating element underneath
• Reduces conductive and radiation heat loses by
reducing exposure to air currents and by providing
warm environment
• Reduces evaporative losses by maintaining high
humidity in the incubator
• Radiation loses curtailed by hood
11. INCUBATORS
ADVANTAGES:
- Reduces insensible water loss
- For transporting babies
- Used as barrier nursing for isolating an infected
baby
- Incubator with rocking bed attachment provides
stimulation to an apnoeic baby
DISAVANTAGES :
- Costlier
- Less accessibility
- Increase risk of infection
