25. Alterações bioquímicas e cardio-respiratórias de Tilápia do Nilo (Oreochromis niloticus) frente à exposição sub-letal ao sulfato de cobre.
The present study evaluated the biochemical, hematological and cardio-respiratory responses of Nile tilapia (Oreochromis niloticus) to copper sulfate (CuSO4). A group of fish (T2; n = 8) was exposed to 50% of a CL50 (48 h) of CuSO4, while the control group (T1; n = 8) was submitted to the same conditions of water quality without CuSO4. Samples of blood, gill

26. Avaliação dos efeitos hemodinâmicos, respiratórios, metabólicos e sedativos da dexmedetomidina isolada ou associada à tiletamina-zolazepam em cães. Estudo experimental / Hemodinamic, respiratory, metabolic and sedative effects evaluation of dexmedetomidine alone or associated with tiletamine-zolazepam in dogs. Experimental study
The aim of the present study was to evaluate hemodynamic, respiratory and metabolic alterations, the quality of induction and recovery of the animal, as well as sedation and muscular relaxation promoted by the use of dexmedetomidine alone or associated to tiletamine-zolazepam. Eighteen healthy male and female mongrel dogs were used and randomly assigned to t

27. Estudo comparativo de dois metodos de ventilação mecanica : hipercapnia permissiva em volume controlado e hipercapnia permissiva em pressão controlada, em pacientes com a sindrome da angustia respiratoria aguda
The main goal of this study was to compare two methods of mechanical ventilation associated to the Permissive Hypercapnia, applied on patients with ARDS, since there is not a preceding consensus concerning the best ventilation . modality associated to the adoption of small flowing volumes, in regard to the minimal of pulmonary aggression to the preexistent l

28. Comparação entre dois metodos de retirada do suporte ventilatorio em pacientes no pos-operatorio de cirurgia cardiaca
NTRODUCTION. Usually, there is no weaning difficulty in mechanical ventilated post-operative coronary artery bypass grafting (CABG) patients, but the literature is not consensual in relation to the best weaning method and the ideal moment for extubation. OBJECTIVE. To compare two weaning methods in uncomplicated CABG post-operative patients by evaluating cli

29. Variabilidade da frequencia cardiaca : estudo das influencias autonomicas sobre suas caracteristicas temporal e espectral em halterofilistas e sedentarios
The aim of this study was to investigate the heart rate variability (HRV) in Time (TD) and Frequency (FD) domain in anaerobic, static and isometric exercises, trained individuaIs (weight lifters (WL), n=ll; mean age = 23 ±1,9 years) and healthy untrained subjects (sedentaries (S); n=ll, mean age = 25,5 ± 4,5 years). Volunteers were submitted to: 1) clinica

30. SIMVEP - Simulador da Ventilação pulmonar
It has been developed a computer program to simulate a patient pulmonary circuit under ventilatory support. The Pulmonary Ventilation Simulator (SIMVEP) runs under MS Windows and is a useful tool for trainning ali the professionals linked to artificial ventilation (physicians, nurses and physiotherapists, amongst others). The real time execution of SIMVEP al

31. Anestesia para microcirurgia do laringe com laser : avaliação de uma tecnica ventilatoria
The CO2 laser used in larynx microsurgery can determine ignition on the airway caused by high temperatures researched by tissue interactions or by reflective beam from surgical or anesthetic instruments. Ventilatory thecniques, intending to reduce the ignition risks by using endotracheal tubes protected with mettalic tapes or, even, by mettalics tubes, were

32. Respostas cardio-respiratorias ao exercicio fisico dinamico em mulheres sedentarias no segundo trimestre de gravidez / Cardiorespiratory responses to dynamic exercise in sedentary women during the second pregnancy trimester
This cross-sectional research was designed to evaluated the cardiorespiratory responses to the moderated dynamic exercise in sedentary women during the second trimester of pregnancy. This work intends to offer new data that will permit a better evaluation in the application of physical activities during pregnancy. Fifteen sedentary women volunteend and were

33. An annual cycle in the ventilatory capacity of men with pneumoconiosis and of normal subjects
The forced expiratory volume over 0·75 second (F.E.V.0·75) was measured monthly for 3 years in 28 working ex-miners with pneumoconiosis and for one year in 17 normal laboratory workers. A significant annual cyclical variation of 0·044 litre amplitude was found in the ex-miners, with minimum and maximum values on 2 February and 3 August respectively. In th

34. On a pseudo-rebreathing technique to assess the ventilatory sensitivity to carbon dioxide in man.
1. The ventilatory sensitivity to carbon dioxide obtained from a step-ramp CO2 challenge was compared to the CO2 sensitivity from the steady-state method. 2. Experiments were performed in nine healthy male subjects against a background of hyperoxia and in two subjects against a background of normoxia. 3. In each subject experiments were performed in which th

35. Ventilatory acclimatization to chronic hypoxia: relationship to noradrenaline metabolism in the rat solitary complex.
1. The relationship between ventilatory acclimatization to chronic hypoxia (10% O2-90% N2) and noradrenaline metabolism was examined in two regions located immediately caudal and rostral to the obex within the rat solitary complex. 2. Three experimental protocols were established. In protocol 1, the percentage changes in respiratory tidal volume, frequency a

36. A dynamic analysis of the ventilatory response to hypoxia in man.
1. The dynamics of the ventilatory response to isocapnic hypoxia were studied in seven healthy subjects using four different levels of hypoxia, (inspired oxygen pressures, PI,O2 equal to 110, 100, 80 and 60 mmHg) successively increasing and decreasing stepwise. 2. Five such progressions were performed for each subject, corresponding to five different duratio
