A comparison of the continuous positive airway pressures produced by two systems

Abstract

Through our recordings it was possible to observe that the Inter 3 continuous positive airway pressure system was more stable than the underwater seal.

Effects of underwater bubble CPAP on very-low-birth-weight preterm newborns in the delivery room and after transport to the neonatal intensive care unit

“…The ubCPAP system used with VLBW preterm newborns in the delivery room and during transportation to the NICU is simple to assemble, low-cost, and equally as effective or even superior to variable-flow CPAP. The vibrations produced by ubCPAP bubbling are transmitted to the chests of infants under this type of ventilatory support and can contribute positively to the efficiency of gas exchange (Lima et al, 2004). The effectiveness, lower cost, and ease of use of the ubCPAP system are corroborated by other studies that note its use in regions with limited financial resources (Arca et al, 2015;Bohlin, 2012;McAdams et al, 2015).…”

Análise de resposta dinâmica do módulo eletro-pneumático da pressão positiva contínua na via aérea modelado por Bond Graph

“…The Continuous Positive Airway Pressure for Newborns (Neo-CPAP) device is used to maintain the airway at a pressure above the ambient throughout the breathing, and thus preventing the complete removal of the inspired gas, while maintaining high stability. This technique was applied in cases of hyaline membrane disease in 1971, in which the use of this treatment was able to maintain a normal spontaneous breathing rate with excellent results (Lima et al, 2004). Currently its application occurs mainly among newborns of very low weight, since this technique provides increased functional residual capacity (FRC), pulmonary compliance (PC) and especially the reduction of intrapulmonary deviation, in which an improper deviation occurs in the ventilation-perfusion ratio (V/Q), besides the reduction of oxygen diff usion (Kamper, 1999).…”

Novo dispositivo EPAP subaquático no pós-operatório de cirurgia de revascularização do miocárdio

“…Dentre as complicações pulmonares pós-operatórias, a mais frequente é a atelectasia, que compromete um segmento, um lobo ou todo um pulmão (6). Chamase atenção para o fato de que, após cinco minutos de indução anestésica, pode-se observar, por tomografia computadorizada, a formação de atelectasia nas porções dependentes dos pulmões.…”
