Στην παρούσα διπλωματική παρουσιάζεται η εξομοίωση της μεθόδου για την μη επεμβατική μέτρηση της γλυκόζης στο αίμα. Η καρδιά της μεθόδου είναι ο μικροεπεξεργαστής της Texas Instruments Msp430f169, τον οποίο και προγραμματίσαμε σε γλώσσα C. Η φυσική αρχή λειτουργίας που στηριχθήκαμε είναι ο νόμος απορρόφησης του φωτός του Beer - Lambert. Το αναλογικό σήμα το μετατρέψαμε σε ψηφιακό με τη χρήση του ADC12 μετατροπέα, το οποίο είναι περιφερειακό στοιχείο του μικροεπεξεργαστή. / This thesis presents the simulation method for non-invasive measurement of blood glucose. The heart of this method is its microprocessor, Texas Instruments Msp430f169, which was programmed in language C. The physical principle of operation supported is the law of light absorption of the Beer - Lambert. The analog signal is converted to digital, using the ADC12 converter, which is a regional component of the microprocessor.

Sua aplicação ocorre em quase metade dos pacientes dessas unidades. Entretanto, a VMI associa-se a várias complicações, especialmente quando utilizada por período prolongado. Desse modo, preconiza-se que a interrupção do suporte ventilatório seja realizada assim que possível. A intempestividade em realizar tanto o desmame como a extubação pode gerar graves conseqüências ao paciente, incluindo a necessidade de reintubação. Esta, por sua vez, está relacionada à elevada incidência de pneumonia hospitalar, o que leva ao maior tempo de ventilação mecânica, de permanência na terapia intensiva, aumento no custo hospitalar e da mortalidade. Visto que tanto a ventilação mecânica prolongada como sua retirada prematura podem ser prejudiciais, faz-se necessário o reconhecimento do momento ideal do desmame e extubação. Vários índices fisiológicos foram propostos com o intuito de identificar os pacientes capazes de reassumir a ventilação espontânea. Poucos ofereceram poder preditivo satisfatório e o índice de respiração rápida e superficial parece ser o mais útil devido sua simplicidade e confiabilidade. No entanto, o melhor ponto de corte dos índices fisiológicos raramente foi estabelecido por curva ROC, evidenciando a necessidade de novos estudos. Neste trabalho, foram revisados os estudos que demonstraram a importância da utilização de protocolos de desmame e extubação e avaliaram o papel preditivo dos índices propostos. / Invasive mechanical ventilation is crucial in intensive care units and its application becomes necessary in almost half of the patients. However it has been associated to several complications especially under prolonged use. Therefore it is reccomended that the discontinuation of ventilator support must be attemped as soon as possible. The premature weaning or extubation also can gerate negative consequences to the patient, including the need of reintubation. This is most related to higher incidence of nosocomial pneumonia, increased IMV use and ICU length of stay, hospital costs and elevated mortality rates. Because of both, prolonged IMV and it’s premature discontinuation can be harmful, it is necessary to recognize the optimal moment for weaning and extubation. Many physiological indexes were proposed to distinguish patients ready to breath spontaneously, but fewness demonstrated satisfatory predictive power. Rapid shallow breathing index seems to be the most useful parameter because of its simplicity and reliability. However, in rare studies the best threshold for these indexes was established by ROC curve, making evident the need of further investigations. The present study reviewed articles that demonstrated importance of weaning and extubation protocols utilization and that assessed the predictive role of physiological indexes.
