ventilatory weaning response, dysfunctional

(vent′ĭl-ă-tor″ē) ABBR: DVWR. Inability to adjust to lowered levels of mechanical ventilator support that interrupts and prolongs the weaning process. SEE: Nursing Diagnoses Appendix.

Left lateral view


fourth v. The most caudal of the cerebrospinal fluid (CSF)-filled cavities inside the brain. The fourth ventricle extends beneath the cerebellum in the roof of the hindbrain from the caudal end of the cerebral aqueduct to the central canal of the medulla (above the middle of the olivary nuclei). The choroid plexus inside the fourth ventricle adds CSF to the fluid draining through the cerebral aqueduct from the third ventricle. CSF flows out of the fourth ventricle into the subarachnoid space surrounding the brain and spinal cord, exiting through three small openings: the median aperture (foramen of Magendie) and the two lateral apertures (foramina of Luschka).

laryngeal v. The space within the larynx between the vestibular and vocal folds.

lateral v. One of the two mirror-image, cerebrospinal fluid (CSF)-filled cavities inside the cerebral hemispheres of the brain. Each lateral ventricle is C-shaped and ...
