3,3′-Diaminobenzidine (DAB) is an organic compound with the formula (C 6 H 3 (NH 2) 2) 2. This derivative of benzidine is a precursor to polybenzimidazole , which forms fibers that are renowned for their chemical and thermal stability. [ 1 ]
Bronchoalveolar lavage (BAL), also known as bronchoalveolar washing, is a diagnostic method of the lower respiratory system in which a bronchoscope is passed through the mouth or nose into an appropriate airway in the lungs, with a measured amount of fluid introduced and then collected for examination.
The ventilator prevents the accumulation of carbon dioxide so that the lungs don't collapse due to the low pressure. [2] [3] The use of artificial ventilation can be traced back to the seventeenth century. There are three ways of exchanging gases in the body: manual methods, mechanical ventilation, and neurostimulation. [4]
Lung volumes. Functional residual capacity (FRC) is the volume of air present in the lungs at the end of passive expiration. [1] At FRC, the opposing elastic recoil forces of the lungs and chest wall are in equilibrium and there is no exertion by the diaphragm or other respiratory muscles.
Fox News host Laura Ingraham says a "real president answers questions" as she reflects on President-elect Donald Trump's openness with the media on "The Ingraham Angle."
An undocumented immigrant was charged with setting a woman on fire, killing her, as she slept in the New York City subway -- a horrific alleged crime that officials called "beyond comprehension."
The lawsuit filed in Los Angeles by fashion designer Bryana "Bana" Bongolan alleges the incident happened in 2016 while she was at the home of Mr Combs' then-girlfriend Casandra "Cassie" Ventura.
Static lung compliance is the change in volume for any given applied pressure. [1] Dynamic lung compliance is the compliance of the lung at any given time during actual movement of air. Low compliance indicates a stiff lung (one with high elastic recoil ) and can be thought of as a thick balloon – this is the case often seen in fibrosis .
