It is up to the ICU nurse to determine how the IV tubing between the infusion pumps and patient should be arranged, preferably using a minimal number of lumens in order to avoid discomfort and catheter-related infections.
However, even with additional lumens, it was difficult in some patients to avoid overdosing the ribs and skin surface (<5 mm to the balloon surface).
Because the neurons must be connected with the exterior, they developed a porous sensillar cuticular wall and, to avoid desiccation, they also developed an aqueous lumen around their chemosensory neurons.
The latter systems prevent secretion of misfolded proteins and direct them to be degraded; UPR signalling pathways, specifically designed to avoid accumulation of unfolded proteins in the ER lumen, are essential for adaptation to altered homeostatic conditions, including redox changes.
We hypothe-sised that by using an indwelling 16 G single lumen central venous catheter in uncomplicated large effusions, we would be able to avoid repeated thoracentesis procedures and to successfully drain large effusions with minimal complications.
To avoid the acidic environment of the interior of the stomach (lumen), H. pylori uses its flagella to burrow into the mucus lining of the stomach to reach the epithelial cells underneath, where the pH is more neutral.
This conscience, unlike the voice of God or what later thinkers called lumen naturale, gives no positive prescriptions; it only tells us what not to do, what to avoid in our actions and dealings with others, as well as what to repent of.
Type III endoleak, secondary to the disconnection of different stent-graft elements, requires immediate treatment to avoid severe complications due to continuous flow within the aneurysm or the false lumen.
Venous access was obtained via a coaxial double lumen catheter of 14 French in the internal jugular or femoral vein, not adjacent to the PiCCO catheter to avoid distortion of the thermodilution curve.
