Temperature Measurement Sites

Temperature Measurement Sites

A thermometer measures body temperature. The common sites for measuring body temperature are the oral cavity, axillary region, temporal artery, and skin surface, such as the forehead, abdomen, and axilla. True core body temperature is assessed in the rectum, tympanic membrane, pulmonary artery, esophagus, and urinary bladder.
Oral: When assessing oral temperature, the thermometer tip should be placed under the tongue in the posterior sublingual pocket. It offers accurate readings and can be...

Equipments Used to Measure Body Temperature

Equipments Used to Measure Body Temperature

Body temperature can be assessed using various devices and measured in Celsius or Fahrenheit.
Glass-bulb Thermometer:
Glass-bulb thermometers are hollow glass tubes with a bulb tip containing liquid such as ethanol or mercury. Historically, glass bulb mercury thermometers were the standard device to measure body temperature. Today, mercury thermometers are prohibited in many countries due to the hazardous effects of mercury and the risk of exposure if the glass bulb breaks. In general,...

Assessing Body Temperature - Tympanic membrane

Assessing Body Temperature - Tympanic membrane

Assessing tympanic membrane temperature involves using a tympanic membrane thermometer (TMT). Here is a step-by-step guide:
Step 1: Begin by practicing good hand hygiene to prevent the transmission of microorganisms.
Step 2: Turn on the thermometer and wait until the ready sign appears on the screen to ensure accurate measurement.
Step 3: Slide the probe cover in place to prevent cross-contamination.
Step 4: Instruct the patient to tilt their head to the side for comfort and check for cerumen...

Background:

Therapeutic hypothermia is crucial for treating hypoxic-ischemic encephalopathy (HIE) and traumatic brain injury (TBI) in infants.
Accurate brain temperature monitoring is essential for effective therapeutic hypothermia.
Current monitoring methods may be invasive or lack precision.

Purpose of the Study:

To develop a flexible antenna for non-invasive microwave brain temperature sensing in infants.
To evaluate the antenna's performance in realistic bending conditions simulating placement on an infant's head.
To aid in optimizing therapeutic hypothermia treatment for HIE and TBI.

Main Methods:

Design and simulation of a circular complementary split ring resonator (CCSRR) antenna on a flexible Kapton substrate with a PDMS superstrate.
Investigation of antenna performance in planar and bent (cylindrical, spherical with 55 mm radius) configurations.
Measurement of thermal noise power from underlying tissue layers for temperature sensing.

Main Results:

The CCSRR antenna operates effectively at the 1.4 GHz radio-astronomy quiet band.
The antenna demonstrates sharp frequency selectivity, strong field confinement, and suppression of external interference.
Stable performance was observed under various bending conditions, with good agreement between simulated and measured results.

Conclusions:

The proposed flexible CCSRR antenna is suitable for non-invasive infant brain temperature monitoring.
The antenna's design and performance support its application in therapeutic hypothermia for HIE and TBI.
Metamaterial-inspired flexible antennas offer a promising approach for advanced medical sensing applications.
