This microprocessor based drug infusion control system is intended to aid doctors and nurses in the care of critically ill cardiac patients. The patient's arterial blood pressure is monitored and the infusion rate of the vasodilator sodium nitroprusside is regulated based on a model reference adaptive control algorithm. The algorithm employs a reference model to approximate the patient drug response. The reference model output is compared with the patient blood pressure change and the...
Show moreThis microprocessor based drug infusion control system is intended to aid doctors and nurses in the care of critically ill cardiac patients. The patient's arterial blood pressure is monitored and the infusion rate of the vasodilator sodium nitroprusside is regulated based on a model reference adaptive control algorithm. The algorithm employs a reference model to approximate the patient drug response. The reference model output is compared with the patient blood pressure change and the adaptive controller parameters are changed bringing the patient drug response in closer agreement with the reference model. Drug infusion is digitally controlled by a microprocessor based system and employs a stepper motor driven peristaltic pump. Simulation studies have validated the system. Animal experiments and clinical studies will be conducted later.

- Abstract/Description
-
Several adaptive controllers have been designed to control the infusion of the drug sodium nitroprusside for the purpose of reducing high blood pressure in post surgical patients. Most of these controllers have not considered one or more factors of the controlled system including the stochastic background noise present in the patients, the time varying nature of the patient, and the constraints imposed on the control input and system output. This thesis presents a model reference adaptive...
Show moreSeveral adaptive controllers have been designed to control the infusion of the drug sodium nitroprusside for the purpose of reducing high blood pressure in post surgical patients. Most of these controllers have not considered one or more factors of the controlled system including the stochastic background noise present in the patients, the time varying nature of the patient, and the constraints imposed on the control input and system output. This thesis presents a model reference adaptive controller which takes into account all of these factors. Through simulations on a personal computer, the robustness of the controller is demonstrated in the presence of noise, time varying parameters, and deterministic disturbances. Furthermore, this performance is achieved without requiring any prior knowledge of the system delay.

- Design of a high signal to noise ratio electrical impedance plethysmograph.

- Abstract/Description
-
We have developed a high signal to noise ratio automatically resetting electrical impedance plethysmograph for noninvasive determination of blood pressure in pigeons. Pigeons are finding increased use as an economical and appropriate animal model for the study of human atherosclerosis. The impedance plethysmograph obtains the pulsatile arterial volume change as an impedance pulse. Nyboer's equation may then be used to extract the arterial volume change from the impedance pulse. The designed...

The impedance plethysmograph obtains the pulsatile arterial volume change as an impedance pulse. Nyboer's equation may then be used to extract the arterial volume change from the impedance pulse. The designed impedance plethysmograph has a sensitivity of 430 mV/m$\Omega$ and a noise level of 0.12 m$\Omega$ peak-to-peak, significantly better than systems reported earlier. Refinements to further enhance the performance are also presented.

- Effects of A Faith-Based Health Devotional on Illness Representation of High Blood Pressure in African Americans.

The African American population has persistently suffered a greater disease burden from uncontrolled high blood pressure than any other ethnic/racial group. There have been many attempts to reduce the health disparity but with little changes in adverse outcomes over the years. As African Americans are very religious and incorporate spirituality into their everyday lives, this research followed a faith-based approach and was conducted in the church setting.

Show moreThe African American population has persistently suffered a greater disease burden from uncontrolled high blood pressure than any other ethnic/racial group. There have been many attempts to reduce the health disparity but with little changes in adverse outcomes over the years. As African Americans are very religious and incorporate spirituality into their everyday lives, this research followed a faith-based approach and was conducted in the church setting. The study was guided by the Illness Representation Model (IRM) and the Theory of Culture Care Diversity and Universality (TCCDU). One hundred male and female participants were recruited from five African American churches in Southeast Florida. Each participant met the inclusion criteria of being 35-80 years old, diagnosed with high blood pressure, members/attendees of a Judeo Christian church, and able to read and write English. A researcher-developed, five-day faith based health devotional which included high blood pressure education infused with Bible messages was used as the intervention. A quasi-experimental design of pre and posttesting was employed to evaluate high blood pressure knowledge and illness representation. High blood pressure knowledge was tested using the High Blood Pressure Prevention IQ Quiz (HBPP-IQ) and illness representation tested with the Revised Illness Perception Questionnaire (IPQ-R). The results demonstrated statistically significant improvements in four out of the five hypotheses tested, with a caveat for the timeline representation (presented as two separate outcomes). The findings indicated: High blood pressure knowledge (HBPP-IQ): p < .000; Illness Representation (IPQ-R); timeline acute/chronic: p = .003; timeline cyclical: p = .20; consequences: p = .024; personal control: p = .0005; treatment control: p = .002. These results support the use of the faith-based teaching method in educating African Americans about high blood pressure as an effort that might improve illness representation in this population.
