The Blood Pressure Analysis on Critically Ill Patients

NCT03827369 | Unknown

• 1 other identifier: TYGH107041
• Study Type: observational
• Target: 100
• Locations: 1 country
• Sites: 1

Brief Summary

The study is to explore the relationship between coefficient of variation of harmonic magnitude (HCV) and different organ failures among those critically ill patients. In the future, we can act as a warning system on patients with multiple organ failures or terminal illness, also as an indicator of treatment effect.

Conditions

Multiple Organ Failure; Intensive Care Unit Syndrome

Keywords

Blood pressure; Arterial pulse; Coefficient of variation of harmonic magnitude

Outcome Measures

Primary Outcomes (1)

• Coefficient of variation of harmonic magnitude

  We measure the blood pressure of participants with multiple organ failures (MOF) by pressure transducer during the 6 months study in the ICU of Taoyuan General Hospital. The radial artery pressure pulse of both hands are recorded with a pressure transducer fixed on the skin with tape and an adjustable belt with a small button to achieve suitable pressure.

  15 min

Study Arms (1)

ICU patient

Pulse pressure of the radical artery was obtained by arterial line. The output of the transducer was connected to an IBM PC for analysis via an A/D converter with sampling rate = 250 datapoints/sec. The pulse spectrum was analyzed with the Fourier transformation using T (period) = 1 pulse time.

Diagnostic Test: ICU patient

Interventions

ICU patient DIAGNOSTIC_TEST

Our study is to measure the coefficient of variation of the HCV of the radial arterial pulse among ICU patients with multiple organ failures (MOF). Patients admitted to Taoyuan General Hospital were recorded during the 6 months study.
