En pacientes con falla cardiaca: This would explain the proportion of pulmonary volume in relation to the body weight, such as the correlations reported here, since the efficiency of gas exchange in this organ increases in the first years of life allowing the reduction of its mass in relation to the body weight.

A description of a prototype miniature extracorporeal membrane oxygenation circuit using current technologies in a sheep model. Anthropometric data and those related to the total results of pulmonqr lungs were expressed descriptively.

The objective of this study was to quantify the volumes of air and tissue, as well as the distribution of pulmonary aeration in this population. Those anomalies in the formation of the heart occur during intra-uterine life and include a large variety of cardiocirculatory malformations, ranging from patent ductus arteriosus to absence of interatrial and interventricular septi.

Respiratory dysfunction is common in children with acyanotic congenital heart defects ACHD with pulmonary hyperflow; however, little is known about the pulmonary structure of those patients.

Nijkeuter M, Sohnc M, et al. The tissue volume measured by the CT represents the summation of the volumes of the pulmonary parenchyma, blood and its cellular components, and pulmonary extravascular water. The right panel of figure 4 shows that the fraction of pulmonary parenchyma classified according to the degree of aeration in relation to the total weight of the parenchyma are compared between the right and left lungs.


The oxygenator has hiperfluko blood flow range of 0. This oxygenator is designed exclusively for neonates and infants and has the smallest priming volume of any clinically available oxygenator. La hipoxia es agravada por tres factores adicionales: Hemodynamic effeets of fluid loading in acute massive pulmonary embolism.

Todo paciente con sospecha de tromboembolismo pulmonar debe ser hospitalizado. When tissue and air were considered as a fraction of the total lung volume, it was observed that they represented Since patients were unable to follow commands for apnea, the test was done during spontaneous breathing after the children get used to the environment.

In this analysis, the pulmonary parenchyma is classified according to the CT coefficient in: En pacientes hipotensos o con insuficiencia cardiaca no se aconseja dar cargas de soluciones cristaloides superiores a mi.

Seven children with acyanotic congenital cardiopathy with pulmonary hyperflow with mean age of 20 months ranging from 6 to 24 monthsand mean weight 9. Using a combination of chest CT and helium dilution technique, Gattinoni et al.

As mentioned before, studies investigating the pulmonary parenchyma of children without cardiorespiratory diseases with computed tomography are lacking; however, Vieira et al.

The increase in partial pressure of oxygen leads to vasoconstriction of the ductus arteriosus and eventual closure in the first three to four weeks of life. The absence of a control group is another important factor, since one cannot justify performing CT scans in children without cardiopulmonary disorders.

Computed tomographic scan hierflujo. As for the clinic, is characterized by sudden onset dyspnea, tachyeardia, tachypnea. After approval by the Ethics Committee of the institution and signing of an informed consent, seven children with ACHD with pulmonary hyperflow underwent computed tomographies of the chest.


Unfortunately, it is impossible to separate the blood and pulmonary extravascular water components. Due to the increase in circulating blood inside the lungs and consequent increase in the caliber of the pulmonary vessels secondary to pulmonary hyper-flow, an increase in non-aerated pulmonary parenchyma is expected, since voxels that characterize blood, liquid elements, and vascular structures have a CT coefficient close to zero.
