Differential ventilation in unilateral pulmonary artery occlusion.
A case is reported of complete isolated occlusion of the right pulmonary artery resulting in underperfusion of the right lung; this was confirmed radiographically and at thoracotomy. Bronchospirometry showed that there was a reduction of ventilation to the right lung. When this lung alone was supplied with a carbon dioxide rich mixture there was a shift of ventilation towards the normal pattern...
متن کاملPulmonary blood volume in experimental unilateral pulmonary-artery occlusion.
THE behavior of the vascular bed appears to be contradictory. A number of papers indicate that the pulmonary circulation in man shows slight variations in arterial pressure during muscular exercise," after pulmonary resections" or following the occlusion of a main branch of the pulmonary artery." Conversely, other experimental and clinical studies appear to demonstrate that the pulmonary vascul...
متن کاملElectrocardiographic evaluation of broilers during the onset of pulmonary hypertension initiated by unilateral pulmonary artery occlusion.
Electrocardiography previously has been used as a noninvasive method for detecting cardiac hypertrophy associated with pulmonary hypertension syndrome (PHS, ascites). In the present study, 36 of 100 male broiler chicks were selected for inclusion in the experiment based on their hatch weight (> or = 40 g), Day 1 to 14 BW gain (upper 50% of population distribution), and the normalcy of their Day...
متن کاملEffect of unilateral anoxia on pulmonary circulation.
Measurements were made of venous drainage from the right and left lower lobes of dogs' lungs. Blood supply was nonnnl and breathing spontaneous. One lung was ventilated with air or oxygen and the other with nitrogen. Control and experimental flows were highly variable and though the anoxie lung received a smnller flow that was significantly different, the physiologic consequence of this fact is...
متن کاملAtrial natriuretic peptide response to unilateral pulmonary artery occlusion.
To test the hypothesis that neural mechanisms evoked by unilateral pulmonary artery occlusion (UPAO) affect the release of atrial natriuretic peptides (ANP) from the heart, hemodynamics and levels of plasma ANP and cyclic guanosine monophosphate (c-GMP) were studied in 11 patients with lung cancer. The UPAO induced a significant rise in heart rate by 5.3 percent, increased mean pulmonary artery...
