A resistor of the flow associated to a system of under water Seal, used to analyse two Generator Systems of continuous positive pressure with different internal diameters of the Branch Bubble,A resistor of low water flow associated to seal.In a model of pulmonary test, we measured the pressure generated by each resistor System, Working pressure of 3 to 10 cmh\u2082o and with a Flow of 6 to 18 T.S. its Monday.The resistor to seal water flow associated with large Branch under the bubble produced Lower pressures (x 5.121 cmh\u2082o (P = 0.0001).The resistor with small Branch Under Water Seal Bubble generated Greater pressures (x 8.541 cmh\u2082o (P = 0.0001).The resistor with large Bubble Water Seal under Branch was the biggest pressure (1952 cmh\u2082o X Delta P = 0.0001) and Lower pressures (X cmh\u2082o 5868 (P = 0.0001).The resistor of the flow associated to seal under water with Bubble Small Branch presented no differences in pressures (P = x 6.347 cmh\u2082o May 2) and generated the lowest pressure (delta X 0.Cmh\u2082o 873 (P = 0.0001). There was an interaction between the resistors and the Working pressures studied and an additive effect between Systems and Flow resistors in pressure Generation.In conclusion, the pressure Generation was associated to the Immersion depth of the bubble diameter and Branch,The resistor has a Stabilizing effect of flow generated pressure.Un resistor de flujo asociado a un sistema de sello bajo agua, empleado para analizar dos sistemas generadores de presión positiva continua con diferentes diámetros internos de la rama burbujeadora, un resistor de flujo asociado a sello bajo agua. En un modelo de test pulmonar, se midieron las presiones generadas por cada sistema resistor, en presiones de trabajo de 3 a 10 cmH₂O y con un flujo de 6 a 18 l.p.m. El resistor de flujo asociado a sello bajo agua con rama burbujeadora grande produjo las menores presiones (X 5.121 cmH₂O p = 0.0001). El resistor de sello bajo agua con rama burbujeadora peq
