Esophageal capnometry The esophagus was intubated orally with a 22-gauge, 1.5-inch-long catheter.

We suggest that esophageal capnometry could be used as an alternative to gastric tonometry for assessing splanchnic hypoperfusion.

(See capnometry.)

Studies have demonstrated that sublingual capnometry, a relatively noninvasive procedure, correlates with gastric tonometry [ 26, 40, 41, 42].

Capnometry and end-points of resuscitation An interesting observation in the present study was the delayed recovery of base deficit after resuscitation (Table 1), whereas Pe CO 2 , Pa CO 2 , and the gap between them were actually recovered (Fig.
