Measurement of Blood Pressure01:17

Measurement of Blood Pressure

1.8K
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...

Assessing Blood pressure using a doppler ultrasound

1.8K
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.

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...

Area of Science:

  • Biomedical Engineering
  • Cardiovascular Physiology
  • Signal Processing

Background:

  • Blood pressure (BP) waveform contains more physiological information than discrete systolic (SBP) and diastolic (DBP) values.
  • Existing photoplethysmogram (PPG) signal models primarily estimate SBP and DBP but are sensitive to noise.

Purpose of the Study:

  • To develop a model for estimating the complete BP waveform, not just discrete SBP and DBP values.
  • To utilize raw PPG signals for comprehensive BP waveform analysis.

Main Methods:

  • A generalized regression neural network (GRNN) model was developed to estimate BP waveforms from raw PPG signals.
  • The model incorporates encoders and decoders for time and frequency domain waveform conversion.
  • SBP and DBP were extracted from the estimated BP waveform.

Main Results:

  • The model achieved a mean absolute error of 3.96 ± 5.36 mmHg for SBP and 2.39 ± 3.28 mmHg for DBP.
  • Root mean square errors were 5.54 for SBP and 3.45 for DBP.
  • Results met the AAMI standard and achieved Grade A under the BHS standard.

Conclusions:

  • The proposed GRNN model effectively estimates BP waveforms using only raw PPG signals.
  • This approach offers a promising non-invasive method for detailed blood pressure monitoring.
