Assessing Body Temperature - Temporal Artery

Assessing Body Temperature - Temporal Artery

Here is a stepwise guide to assessing the body temperature at the temporal artery using a temporal artery thermometer
Step 1: Perform hand hygiene and don a fresh pair of gloves to prevent cross-infection and ensure patient safety.
Step 2: Explain the procedure to the patient to establish trust. Clear communication establishes trust with the patient, ensures they understand what to expect, promotes cooperation, and enhances comfort during the procedure.
Step 3: Assess the patient's forehead...

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...

Assessing Body Temperature - Rectal

Assessing Body Temperature - Rectal

Rectal temperature measurement is considered the most precise method for assessing core body temperature and typically registers higher than oral temperature. For adults, the rectal thermometer should be inserted 1 to 1.5 inches into the rectum to obtain the most accurate reading.
Follow these steps for rectal temperature assessment:
Step 1: Perform hand hygiene and don clean gloves to prevent cross-infection.
Step 2: Position the patient in a side-lying position to better visualize the rectal...

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,...

Summary

Cold exposure affects nerve function, but transcarpal median nerve conduction velocity (NCV) is least impacted. This suggests transcarpal median NCV may be more reliable than sensory and motor latencies in cold conditions.

Background:

Temperature significantly influences nerve conduction properties, including sensory and motor latencies and nerve conduction velocity (NCV).
Understanding how different nerve conduction parameters are affected by cold is crucial for accurate physiological assessments in varying environmental conditions.

Purpose of the Study:

To investigate the differential effects of cold exposure on distal sensory and motor latencies versus transcarpal median nerve conduction velocity (NCV).
To identify which nerve conduction parameter is least affected by cold, thereby determining its potential reliability in cold environments.

Main Methods:

Thirty-two healthy young adults (18-28 years) participated.
Skin temperature at the wrist was monitored.
Distal median motor and sensory latencies, along with transcarpal median NCV, were recorded before and after cold water immersion.
Paired t-tests were used for statistical analysis.

Main Results:

All measured nerve conduction parameters were affected by cold exposure.
Transcarpal median NCV exhibited a less pronounced reduction compared to distal sensory and motor latencies.
Cold immersion resulted in significant changes across all parameters, but the magnitude of change varied.

Conclusions:

Transcarpal median nerve conduction velocity (NCV) is the least affected parameter by cold exposure among those studied.
Transcarpal median NCV demonstrates greater reliability than distal sensory and motor latencies when assessing nerve function in cold conditions.
