Some of the differences between the CPAP and the BiPAP are that the CPAP pressure setting is fixed while the BiPAPâs can be adjusted. The CPAP delivers one level of air pressure while the BiPAP delivers two. A CPAP is less expensive than a BiPAP, while the BiPAP tends to be slightly noisier than the CPAP.
Anaerobic bacteria are bacteria that do not live or grow in the presence of oxygen. In humans, these bacteria are most commonly found in the gastrointestinal tract. They play a role in conditions such as. , , and.
Anaerobic infection. Anaerobic infections are caused by anaerobic bacteria. Obligately anaerobic bacteria do not grow on solid media in room air (0.04% carbon dioxide and 21% oxygen); facultatively anaerobic bacteria can grow in the presence or absence of air. Microaerophilic bacteria do not grow at all aerobically or grow poorly, but grow better under 10% carbon dioxide or anaerobically.
