Assessing Blood pressure using a doppler ultrasound01:19

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
  • Medical Devices
  • Clinical Monitoring

Background:

  • Wearable biosensor technologies offer potential for early detection of clinical deterioration in postoperative care.
  • Continuous monitoring can significantly improve patient outcomes and reduce healthcare burdens.

Purpose of the Study:

  • To validate the accuracy of the Cloud DX Vitaliti continuous vital signs monitor (CVSM) for continuous noninvasive blood pressure (cNIBP) measurements in postsurgical patients.
  • To assess user acceptance of the Vitaliti CVSM regarding comfort, ease of use, positioning, and aesthetics.

Main Methods:

  • Validation followed International Standards Organization (ISO) 81060-2:2018 standards for wearable, cuffless blood pressure devices.
  • The Vitaliti CVSM was calibrated against an invasive arterial catheter (gold standard) in 20 postsurgical cardiac ICU patients.
  • Measurements were taken in static and supine positions, with device acceptability assessed through interviews.

Main Results:

  • The Vitaliti CVSM demonstrated mean errors of determination within acceptable limits for both systolic and diastolic blood pressure in static and supine positions.
  • Accuracy compliance with ISO 81060-2:2018 standards was observed when measurements commenced within 2 minutes of calibration.
  • The majority of patients reported the device as comfortable.

Conclusions:

  • The Cloud DX Vitaliti CVSM meets ISO standards for cNIBP measurement accuracy in postsurgical ICU patients within a short validation period after calibration.
  • The device was well-received by patients, indicating good user acceptance.
  • Future research should explore ambulatory accuracy, longer-term use, and the impact of motion on data quality.
