An aneroid sphygmomanometer, commonly used in clinical settings, offers a manual and precise method for blood pressure measurement. The technique for using this instrument involves specific steps that must be carefully executed to ensure accuracy. The following detailed description outlines a two-step technique for assessing blood pressure using...

Sites for measuring blood pressure

Sites for measuring blood pressure

Blood pressure measurement is a fundamental clinical procedure, providing crucial data for assessing cardiovascular health. Among the various sites for this measurement, the brachial and popliteal arteries are predominantly utilized due to their accessibility and the reliability of their readings. This lesson delves into the anatomical significance, methodology, and considerations of measuring blood pressure at these locations.

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 - 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...

Assessing Blood pressure using a doppler ultrasound

Assessing Blood pressure using a doppler ultrasound

To obtain accurate blood pressure measurements in clinical settings, especially when traditional methods are insufficient, healthcare professionals utilize the Doppler ultrasound technique. This method uses high-frequency sound waves to detect blood flow within the arteries, which is crucial for patients with conditions that complicate circulatory system assessment.

Area of Science:

Biomedical Engineering
Cardiovascular Monitoring
Physiological Measurement

Background:

Continuous blood pressure (BP) monitoring is crucial for cardiovascular assessment.
Current noninvasive BP methods face challenges with calibration, artifacts, and detecting rapid changes.
High temporal fidelity is needed for dynamic conditions like perioperative and critical care.

Purpose of the Study:

To introduce and evaluate a novel noninvasive BP monitoring technique using superficial temporal artery tonometry (STAT).
To utilize a biomechanics-based transfer function to enhance accuracy and reduce calibration needs.
To assess the method's ability to detect rapid BP changes in dynamic settings.

Main Methods:

Collected 29 continuous BP monitoring sessions from 10 human subjects.
Simultaneously recorded BP using STAT, a reference device (Finapres/Finometer), and Pulse Transit Time (PTT).
Evaluated performance during rest and handgrip-induced BP fluctuations.

Main Results:

STAT achieved a mean absolute difference (MAD) of 4.8 ± 2.2 mmHg at rest and 6.5 ± 3.4 mmHg during handgrips.
The STAT method significantly outperformed PTT, particularly under dynamic conditions.
Demonstrated improved accuracy and detection of rapid BP fluctuations compared to PTT.

Conclusions:

STAT with a biomechanics-based transfer function provides robust, real-time noninvasive BP monitoring.
This method overcomes limitations of existing techniques regarding calibration, motion artifacts, and detection.
Enables reliable hemodynamic monitoring in dynamic physiological states.
