Cobra 3

Yes, C3P EMG tube is fully interoperable. Designed for universal compatible with any nerve monitoring system. The EMG tube features color-coded lead wires with standard DIN (42802) connectors for an easy set-up on single-channel and multi-channel nerve monitoring systems.

C3P EMG tubes are available in standard endotracheal tube (ETT) sizes: 6 mm, 7 mm, and 8 mm. The low-profile, atraumatic EMG electrodes incorporate intraoperative neuromonitoring technology that has almost zero impact on the size, performance and reliability of the PVC endotracheal tube.

Cobra 3-Plate EMG Tube are fully stocked and all size are available to order.

C3P EMG tube is used in procedures where the recurrent laryngeal nerve (RLN) is at risk of injury; e.g. thyroidectomy, parathyroidectomy, ACDF. The C3P EMG tube is intended to provide two essential functions; intraoperative neuromonitoring with EMG electrodes to identify vocal cord (laryngeal musculature) activity while maintaining an open airway for the patient during surgery.

No, intubation with a C3P EMG tube follows current medical techniques, with the recommendation of using a Glidescope. Once the EMG tube is placed the electrode plates should maintain direct contact with the vocal cords. With the C3P EMG tube, it is important to avoid scraping of the electrodes during intubation. Otherwise, electrode damage from this can impede accurate EMG signals. Once intubated the EMG tube should be secured in a midline position, a side rotation is not recommended.

C3P is similar to most integrated EMG tubes, like the Cobra 2-Ch the solid red and blue lead wires correlate to the lateral electrodes (right and left) but the unique difference is that the 3rd electrode is connected to two lead wires (red/white & blue/white) creating a singular posterior reference electrode. This design optimizes the EMG response by maximizing the area covered by the electrodes and produces redundant monitoring of the vocalis muscles if tube rotation is inadvertently experienced.

No, the redesign of the C3P EMG tube enhanced the length and symmetry of the electrodes to improve the target area. The glottic markings are no longer needed but the depth markings (18 – 24 cm) are present.

Yes, the C3P EMG tube has the longest recording plates of any laryngeal electrode (EMG tube and surface EMG electrodes) on the market allowing it to accommodate large patients and longer airways. To assist in accurate depth placement the 18-24 cm depth markings are visible on the ET tube.

No, although the new electrode geometry is designed to reduce alignment sensitivity, it is recommended that EMG tube be aligned and maintained to the middle of the pharynx and positioned with the red wire on the right and the blue wire on the left. This position creates the proper right/left contact between the vocal cords and its respective electrode/plate.
