Direct Method
This invasive approach involves cannulating a peripheral artery. During each cardiac contraction, pressure generates mechanical motion within the catheter, transmitted through rigid, fluid-filled tubing to a transducer. This transducer converts mechanical motion into electrical signals displayed as waveforms on a monitor. An automatic flushing system prevents blood backflow. Due to the potential risk of unexpected arterial blood loss, this method is primarily used in intensive...

Special considerations while measuring blood pressure

1.1K
When assessing blood pressure (BP), healthcare professionals must consider various factors and potential unexpected outcomes to ensure accurate readings and provide proper patient care. Adhering to these guidelines is essential to achieving the most reliable results.
Monitoring Both Arms:
Monitoring BP in both arms during the initial assessment is advisable, as the systolic value may differ by five to ten mm Hg between arms. For subsequent BP assessments, use the arm with the higher reading.

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.

Assessing blood pressure is a standard procedure executed in virtually all medical environments. The method utilized today was established over a hundred years ago by an innovative Russian doctor, Dr. Nikolai Korotkoff. The soft ticking noise, known as Korotkoff sounds, heard while taking blood pressure readings results from turbulent blood flow within the vessels. The apparatus required for this procedure includes a sphygmomanometer, a blood pressure cuff attached to a gauge, and a...

Area of Science:

  • Biomedical Engineering
  • Cardiovascular Monitoring
  • Wearable Technology

Background:

  • Continuous, non-invasive blood pressure monitoring is crucial for managing hypertension and cardiovascular diseases.
  • Existing methods often lack accuracy, comfort, or continuous monitoring capabilities.
  • Wearable sensors offer a promising avenue for personalized and accessible health tracking.

Purpose of the Study:

  • To develop and validate a signal processing method for estimating systolic blood pressure (SBP) using continuous wave radar (CWR) and other wearable sensors.
  • To assess the efficacy of pulse transit time (PTT) and pulse arrival time (PAT) derived from CWR, Photoplethysmogram (PPG), and Electrocardiogram (ECG) for SBP estimation.
  • To investigate the impact of removing the pre-ejection period (PEP) from PAT on SBP estimation accuracy.

Main Methods:

  • Utilized continuous wave radar (CWR), PPG, and ECG sensors for continuous data acquisition.
  • Implemented a signal processing technique involving wavelet transform and adaptive filtering to denoise CWR signals.
  • Calculated PAT, PEP, and PTT, and applied two mathematical models to estimate SBP from these parameters.

Main Results:

  • Achieved a best cumulative error percentage (CEP) of 92.28% for posture tasks and 82.61% for exercise tasks.
  • Demonstrated that removing PEP from PAT improved SBP estimation results by approximately 9%.
  • Validated the potential of CWR sensors for low-power, continuous monitoring with minimal body contact.

Conclusions:

  • The proposed signal processing method shows significant potential for accurate SBP estimation using wearable PTT measurements.
  • CWR-based PEP extraction offers a potentially superior approach for medical monitoring, including blood pressure measurement.
  • This study highlights the feasibility of CWR technology for developing advanced wearable cardiovascular monitoring systems.
