The positive-pressure breathing system consisted of three main portions: the pressurized helmet, the breathing bladder, and the tankage system in a backpack. The bladder and helmet were connected together to pump air out of the bladder and over the torso when the user breathed in, reducing the amount of pressure on the user's chest. The helmet ...
This helmet can also be used for mixed gas either for open circuit or as part of a modular semi-closed circuit system, which uses a back mounted recirculating scrubber unit connected to the lower back of the helmet by flexible breathing hoses. The helmet uses a neck dam or can be connected directly to a dry suit, and uses a jocking harness to ...
The user respiratory interface is the delivery system by which the breathing apparatus guides the breathing gas flow to and from the user. Some form of facepiece, hood or helmet is usual, but for some medical interventions an invasive method may be necessary. Any given unit is a member of several types.
Maurice Fernez (30 August 1885 – 31 January 1952) was a French inventor and pioneer in the field of underwater breathing apparatus, respirators and gas masks. He was pivotal in the transition of diving from the tethered diving helmet and suit of the nineteenth century to the free diving with self-contained equipment of the twentieth century.
The semi-closed breathing circuit used the injected gas to circulate the gas in the helmet through a scrubber, providing a very low work of breathing in comparison with most other rebreathers which used the lungs of the diver to circulate gas in the loop. The Modell 1915 bubikopf helmet was designed for use with this system. The rebreather loop ...
For substances hazardous to the eyes, a respirator equipped with a full facepiece, helmet, or hood is recommended. PAPRs are not effective during firefighting, in an oxygen-deficient atmosphere, or in an unknown atmosphere; in these situations a self-contained breathing apparatus or supplied-air respirator is recommended instead.
