1. Respiratory evaluation through volumetric capnography among grade III obese and eutrophic individuals: a comparative study
ABSTRACT BACKGROUND: Excess trunk body fat in obese individuals influences respiratory physiological function. The aims of this study were to compare volumetric capnography findings (VCap) between severely obese patients and normal-weight subjects and to assess whether there is any association between neck circumference (NC), waist-hip ratio (WHR) and VCap

2. Effects of pressure controlled ventilation and volume controlled ventilation on pulmonary function in cardiac surgery patients with cardiopulmonary bypass / Efeitos do suporte ventilatorio com pressão controlada e volume controlado na função pulmonar dos pacientes submetidos a cirurgia cardiaca com circulação extra-corporea
Postoperative lung injury after cardiac surgery with cardiopulmonary bypass (CPB) is usually related to the systemic inflammatory response syndrome (SIRS). Many patients undergoing this procedure develop acute lung injury (ALI), and some of them acute respiratory distress syndrome (ARDS). Many factors can be directly or indirectly related to the postoperativ

3. Monitorização respiratoria de lactentes com bronquiolite viral aguda em ventilação mecanica invasiva / Respiratory monitoration in infants with acute viral bronchiolitis on invasive mechanical ventilation
Técnicas de monitorização da função respiratória são recursos importantes no diagnóstico e seguimento das doenças pulmonares em pacientes em ventilação mecânica invasiva (VMI). O presente estudo propiciou a realização de dois trabalhos com os seguintes objetivos: 1)Avaliar a associação entre tempo de VMI, variáveis antropométricas, clínica

4. Evaluation of the dead-space : tidal volume ratio as a predictor of success in the removal of mechanical ventilation of critically ill children / "Avaliação da relação entre espaço morto e volume corrente como índice preditivo de sucesso na retirada da ventilação mecânica de crianças gravemente enfermas"
O momento ideal para a extubação de crianças graves é ainda difícil de ser avaliado. A razão entre espaço morto e volume corrente (Vd/Vt), como valor preditiva de extubação bem sucedida, já foi testada em adultos e crianças. O objetivo deste trabalho foi avaliar a eficácia do Vd/Vt, como preditivo do sucesso da extubação, em crianças de uma UT

5. Assessment of factors that influence weaning from long-term mechanical ventilation after cardiac surgery
OBJECTIVE: To analyze parameters of respiratory system mechanics and oxygenation and cardiovascular alterations involved in weaning tracheostomized patients from long-term mechanical ventilation after cardiac surgery. METHODS: We studied 45 patients in their postoperative period of cardiac surgery, who required long-term mechanical ventilation for more than

6. Anatomical dead space, ventilatory pattern, and exercise capacity in chronic heart failure.
BACKGROUND--Patients with chronic heart failure have an excessive ventilatory response to exercise, characterised by an increase in the slope of the relation between ventilation and carbon dioxide production (VE/VCO2 slope). Patients have an altered respiratory pattern with an increased respiratory rate (f) at a given tidal volume (VT), which may result in i

10. Idiopathic scoliosis. Gas exchange and the age dependence of arterial blood gases.
The aims were to examine the gas exchange and arterial blood gas abnormalities among patients with scoliosis, and the correlation of these abnormalities with age and severity of deformity. Means among 51 patients were as follows: age 25.4 +/- 17.5 yr, angle of scoliosis 80.2 +/- 29.9 (SD), vital capacity 1.94 +/- 0.91 (SD) (i.e. 60.6 +/- 19.2% of predicted),

11. Mechanism of the increased ventilatory response to exercise in patients with chronic heart failure.
Minute ventilation, respiratory rate, and metabolic gas exchange were measured continuously during maximal symptom limited treadmill exercise in 30 patients with stable chronic heart failure. The ventilatory response to exercise was assessed by calculation of the slope of the relation between minute ventilation and rate of carbon dioxide production. There wa

12. Pulmonary function in bronchial carcinoma
Legge, J. S., and Palmer, K. N. V. (1973).Thorax, 28, 588-591. Pulmonary function in bronchial carcinoma. Pulmonary function was measured preoperatively in 330 patients with bronchial carcinoma. Obstructive bronchitis was present in 62%. Of 225 patients considered fit for thoracotomy and lung resection, 13 developed postoperative ventilatory failure and six
