Abstract:
Diagnostic and treatment procedures in laryngology demand the knowledge on physiological processes taking place in nasal cavities in the course of breathing. It is of special importance in treatment with pharmacologic agents exerting an influence on nasal blood vessels and in nasal structures operations. The paper presents electronic thermometer which was specially designed for measurements in human higher airways. The system is set of flexible measurement head with miniature thermistor and microprocessor system connected to the personal computer fit out database application for collect and visualization measurement data. The device is safe for medical doctor and patient as well. With patient point of view, the measurements can be done easily and comfortably. The system allows recording dynamic changes of air temperature in upper airways and recalculates average inspired and expired air temperatures. The paper presents also initial results obtained in group of 15 healthy volunteers and 3 with tracheotomy It was made an estimation nasal ability to heating inspired air in particular places of nasal cavity and determined air temperature in nasal cavity outlet.

Equipments Used to Measure Body Temperature
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,...
Temperature Measurement Sites
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 - Tympanic membrane
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...
Assessing Body Temperature - Oral
Step 1:
Start by practicing proper hand hygiene to prevent the spread of microorganisms.
Step 2:
Take the thermometer out of the charging unit, switch it on, and wait for the ready sign.
Step 3:
Gently slide the probe cover until a click is heard. This simple action prevents cross-contamination and ensures the correct placement of the probe cover.
Step 4:
Instruct the patient to open their mouth and place...
Assessing Body Temperature - Rectal
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...
Assessing Body Temperature - Temporal Artery
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...
