13. Prácticas de destete ventilatorio en las unidades de cuidado intensivo de la ciudad de Cali
Objective: Early weaning from mechanical ventilation is one of the primary goals in managing critically ill patients. There are various techniques and measurement parameters for such weaning. The objective of this study was to describe the practices of ventilatory weaning in adult intensive care units in the city of Cali. Methods: A survey of 32 questio

14. Effect of chronic ethanol exposure on rat ventilatory responses to hypoxia and hypercapnia
OBJECTIVE: The effect of chronic ethanol exposure on chemoreflexes has not been extensively studied in experimental animals. Therefore, this study tested the hypothesis that known ethanol-induced autonomic, neuroendocrine and cardiovascular changes coincide with increased chemoreflex sensitivity, as indicated by increased ventilatory responses to hypoxia an

15. Identification and agreement of first turn point by mathematical analysis applied to heart rate, carbon dioxide output and electromyography
BACKGROUND: The second heart rate (HR) turn point has been extensively studied, however there are few studies determining the first HR turn point. Also, the use of mathematical and statistical models for determining changes in dynamic characteristics of physiological variables during an incremental cardiopulmonary test has been suggested. OBJECTIVES: To

16. Hemodynamic and ventilatory response to different levels of hypoxia and hypercapnia in carotid body-denervated rats
OBJECTIVE: Chemoreceptors play an important role in the autonomic modulation of circulatory and ventilatory responses to changes in arterial O2 and/or CO2. However, studies evaluating hemodynamic responses to hypoxia and hypercapnia in rats have shown inconsistent results. Our aim was to evaluate hemodynamic and respiratory responses to different levels of h

17. Habitat, hábito e morfologia cardíaca: influência destes fatores sobre as respostas cardiorrespiratórias à hipóxia e alterações térmicas em espécies de peixes ecologicamente distintas
Os ambientes aquáticos estão sujeitos a grandes variações em suas propriedades físicoquímicas as quais pode comprometer a sobrevivência dos animais que habitam essas águas, especialmente os peixes, os quais exibem comportamento adaptativo, respostas fisiológicas, bioquímicas e genéticas para enfrentar tais mudanças. O objetivo do presente estudo

18. Toxicidade da deltametrina (formulação Butox CE25) nas respostas cardio-respiratórias da tilápia-do-Nilo (Oreochromis niloticus)
Deltamethrin is a synthetic pyrethroid pesticide, type II, considered of low persistence in the environment and widely utilized in agriculture and aquaculture to control plagues and aquatic parasites respectivamently. In spite of it low toxicity in mammals, this pesticide can be extremely toxic for fish. In this study, we evaluate the effects of a sub-lethal

19. Análise da existência de máxima fase estável de lactato nos exercícios resistidos leg press 45º e supino reto / Analysis of the existance of a maximal lactate steady state on resistance exercises leg press 45° and bench press
The purpose of the study was to verify if there is a maximal lactate steady state (MLSS) for the Leg Press (LP) and Bench Press (BP) exercises and to analyse ventilatory responses ventilation (Ve) and oxygen uptake (VO2), heart rate (HR), blood lactate concentration (BLC) and ratings of perceived exertion (RPE) to those exercises performed on MLSS intensity

20. Comportamento da mecânica ventilatória durante a realização de um atendimento de fisioterapia respiratória
Question: Can Respiratory therapy alter the lung mechanics in patients with invasive mechanical ventilation? The data available in the literature remain controversial. This study aims to assess the changes of pulmonary mechanics in patients with invasive mechanical ventilation, comparing hemodynamic and ventilatory parameters one hour prior to application of

21. Nitrergic mechanisms involved in the neurotransmission of autonomic and respiratory components of chemoreflex in the caudal NTS of awake rats / Mecanismos nitrérgicos envolvidos na neurotransmissão dos componentes autonômicos e respiratório do quimiorreflexo no NTS caudal de ratos não-anestesiados
The nucleus tractus solitarius (NTS) is an integrative area in the central nervous system (CNS) involved with the ventilatory and autonomic control. Several studies suggest that nitric oxide (NO) in the NTS plays an important role in the modulation of the cardiovascular and ventilatory reflexes. In addition, there is evidence indicating a possible interactio

22. Medida dos parâmetros respiratórios na admissão da UTI pode predizer necessidade de suporte ventilatório, tempo de internação e mortalidade / Measurement of respiratory parameters at ICU admission can predict the necessity for ventilatory support, length of stay and mortality
INTRODUÇÃO: Existe uma dúvida na literatura médica se a monitorização respiratória do paciente crítico internado na Unidade de Terapia Intensiva contribuiria para melhora de seu prognóstico. OBJETIVO: Avaliar de maneira prospectiva se a mensuração de parâmetros respiratórios na admissão dos pacientes em ventilação espontânea na Unidade de Te

23. Efeito da dexmedetomidina ou do remifentanil na função renal de pacientes submetidos à cirúrgia bariátrica.
The objective of the present research was to study the comparative effects of dexmedetomidine and remifentanil on the renal function of morbidly obese patients submitted to bariatric surgery. Casuistic and Method: After approval by the local Ethics Council, in the period from August 2004 to August 2005, 61 patients were studied prospectively independent of r

24. IdentificaÃÃo dos limiares de lactato, glicÃmico e ventilatÃrio e efeitos da intensidade do exercÃcio resistido sobre a glicemia em diabÃticos tipo-2
The aim of this study were: 1) to identify the incidence and compare the lactate (LT), glycemic (IGT) and ventilatory thresholds (VT) in cycle ergometer, as well as the lactate (LT)and glycemic thresholds (GT) in resistance exercise in type 2 diabetics; 2) to correlate the thresholds on cycle ergometer with the thresholds determined on resistance exercises;
