As with most nerves in the neck, multiple anatomic variants have been described. Notably, there may be variability in the course of the phrenic nerve in the retro-clavicular region such that the nerve courses anterior to the subclavian vein, rather than its typical position posterior to the vein (between the subclavian vein and artery). [3]
The phrenic nerve is then isolated under the scalenus anticus muscle. For the thoracic surgical technique, a small (~5 cm) incisions over the 2nd or 3rd intercostal space. The electrodes are placed around the phrenic nerves alongside the pericardium. The use of a thorascope allows for this technique to be performed in a minimally-invasive ...
Neurally adjusted ventilatory assist (NAVA) is a mode of mechanical ventilation. NAVA delivers assistance in proportion to and in synchrony with the patient's respiratory efforts, as reflected by an electrical signal. This signal represents the electrical activity of the diaphragm, the body's principal breathing muscle. [1]
The diaphragm is primarily innervated by the phrenic nerve which is formed from the cervical nerves C3, C4 and C5. [7] While the central portion of the diaphragm sends sensory afferents via the phrenic nerve, the peripheral portions of the diaphragm send sensory afferents via the intercostal (T5–T11) [8] and subcostal nerves (T12). [citation ...
They course through the fibrous pericardium. [2] The pericardiacophrenic artery accompanies the phrenic nerve between the pleura and pericardium, to the diaphragm. [3] This is where both the artery and the phrenic nerve are distributed.

In the cervical region, the spinal nerve roots come out above the corresponding vertebrae (i.e., nerve root between the skull and 1st cervical vertebrae is called spinal nerve C1). From the thoracic region to the coccygeal region, the spinal nerve roots come out below the corresponding vertebrae. This method creates a problem when naming the ...
