“…Commonwealth Industrial Gases also manufactured apparatus for oxygen administration and resuscitation. One such device was the "Air-Viva" (Figure 9), a self-inflating bag and mask resuscitator which was first manufactured in 1962 35 . The device consisted of a stiff plastic ventilating bag, a nonrebreathing valve (disc and spring mechanism) and transparent masks, all contained in a portable case.…”

FIRESIDE BELLOWS Simple fireside bellows were used in a number of early experiments which were fundamental to understanding the mechanics of breathing 1-3. It was this understanding which then prompted others to try using the bellows to restore breathing. This early experimental work was done by Galen, Vesalius and Paracelsus. Bellows were formally adopted for resuscitation purposes by the Royal Humane Society, London, in 1782 4. Galen Claudius Galenius (more commonly known as Galen) was born in 130 AD in Pergamon, located in the west of modern day Turkey 1. Galen realised that a knowledge of anatomy was fundamental to understanding disease. Although some of his teachings were erroneous, he made remarkable discoveries based on animal dissections. Unfortunately, the dissection of human cadavers was prohibited at that time. Respiratory physiology interested Galen greatly, and he demonstrated that air entered the chest cavity when it was expanded by the contraction of the diaphragm. Further, he realised that the trachea (which he termed the "rough artery") was the conduit for air into and out of the lungs 1. In 177 AD, Galen used bellows to inflate the lungs of various animals * B.App.

The performance of seven marks of autoinflated resuscitator bag manufactured and/or commercialized in Brazil was studied using a lung-test and an analyzer analogical about: FiO 2 offered for O 2 flow received, O 2 flow offered without manipulation of the compressible unit, patient valve lock-up when resuscitator receives na O 2 flow of 35 l/min, patient valve backward leakage, drop test, inspiratory and expiratory flow resistance, valve function after contamination by vomitus, easy cleaning and information contained in the device. The resuscitators that possess the option for attached the reservoir of O 2 had supplied to a best concentration of FiO 2 with this accessory. The resuscitator that does not have the option of attached of the reservoir of O 2 had presented greater offers of O 2 flow without the manipulation of the compressible unit. The resuscitator that receive O 2 flow from in the interior of the compressible unit, had the valve of the patient fixed when they had received O 2 flow higher than 5 l/min, modifying the peak pressure, the tidal volume and inspiratory and expiratory flow. The resuscitator when used as source of offering O 2 flow without the manipulation of the compressible unit must be with reservoir of O 2 connected and receiving 15 l/min of O 2 . Three resuscitators receiving 35 l/min had been disabled to ventilate the lung test because patient valve lock-up. One resuctitator presented imperfection in the patient valve backward leakage. The highest resistance to the inspiratory flow had been of 7 and 8 cmH 2 O and the highest resistance to the expiratory flow was of 7 cmH 2 O. All resuctitators had passed in the test of valve function after contamination by vomitus and drop test. Any resuctitators offered information about to the flow of safe O 2 to the compressible unit and the offered FiO2. The different models of resuctitators can get different performances.
