Assessing Blood pressure using a doppler ultrasound01:19

Assessing Blood pressure using a doppler ultrasound

1.5K
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.

Pulse Oximetry01:24

Pulse Oximetry

377
Pulse oximetry, or SpO2, is a non-invasive method for continuously monitoring arterial oxygen saturation (SaO2). This procedure involves attaching a probe or sensor to the patient's fingertip, forehead, earlobe, or nose bridge. The sensor works by detecting changes in oxygen saturation levels through light signals generated by the oximeter and reflected by the pulsing blood under the probe.
Purpose
Average SpO2 values are greater than 95%. If the readings fall below 90%, it indicates that...

Introduction to Vital Signs01:25

Introduction to Vital Signs

2.7K
Vital signs are physiological measurements that help key into the status of the body's essential functions. These include body temperature, pulse rate, respiratory rate, and blood pressure, commonly abbreviated as T, P, R, and BP. Some healthcare settings also consider oxygen saturation (SpO2) and, in specific contexts, pain and level of consciousness as additional vital signs.
Vital signs help healthcare professionals assess an individual's well-being and detect any functional changes...

Apical-Radial (A-R) Pulse Assessment
The A-R pulse assessment involves simultaneous evaluation of the apical and radial pulses. When the apical and radial pulse rates vary, this assessment helps identify a pulse deficit.

Background:

  • Smart grids require continuous monitoring of employee health for operational safety.
  • Ultra-wideband (UWB) radar offers non-contact vital sign monitoring due to its penetration and resolution capabilities.
  • Accurate heart rate measurement is challenging due to low signal amplitude and noise.

Purpose of the Study:

  • To develop a robust method for extracting vital signs (respiration and heartbeat) using UWB radar.
  • To enhance the accuracy of heart rate monitoring in noisy environments for grid employees.
  • To validate the effectiveness of the proposed signal processing techniques.

Main Methods:

  • Utilizing ultra-wideband (UWB) radar sensors for non-invasive vital sign detection.
  • Applying Singular Spectrum Analysis (SSA) to reconstruct noisy vital sign data and eliminate interference.
  • Employing Variational Modal Decomposition (VMD) to accurately extract target vital signs.

Main Results:

  • Demonstrated high accuracy in extracting vital sign information from ten subjects at varying distances.
  • Successfully eliminated noise peaks around the heartbeat rate using SSA.
