Variation in V T and P L may occur because of different breath types during PC-IMV, and higher distending pressure may develop during some breath types such as type B breath (Additional file 1: Fig. S1).
During breath-hold imaging, patients take a breath deeper and hold their diaphragm location for an extended period of time (15 30 s), measured as decreased pressure within the tubing during inspiration (b, breath hold).
(B – D ) Mean relative changes of ventilation (VE) (B ), breath duration (TTOT) (C ) and tidal volume (VT) (D ) measured in P0 (control n = 31; mutant N = 13), P2.5 (n = 17; N = 9) and P60 (n = 19; N = 11) mice breathing normal or hypercapnic air (8% CO2).
Example: E, F, F#, G (breath); G#, A, B♭, B (breath), and so on.
(b) Breath-first search K-Best decoder.
The axial T2-weighted (BLADE; a) and the volumetric contrast-enhanced 3D-GRE (VIBE; b) breath-hold acquisitions show severe bronchiectasis, bronchial wall thickening, mucus plugging, pleural effusion as well as a destructed middle lobe.
The chorus includes the lyrics, "It's in his DNA, D-D-D-DNA D-D-D-DNA D-D-D-DNA D-D-D-DNAst takes my breath away, b-b-b-breath away / Itfeel it every day / And that's what makes a man, not hard to understand / Perfect in every way, I see it in-his-face / Nothing more to say, it's in his DNA-D-D-DNA".
Expired air was analyzed with a Quark b breath-by-breath metabolic system (Cosmed, Rome, Italy).
The most accomplished diver, a nineteen-year veteran with a best breath-hold of seven minutes and sixteen seconds, fell within the pathological range of impairment.
