Abstract:
Gastric tonometry is gaining acceptance rapidly as a noninvasive method of monitoring tissue dysoxia in a key organ system that previously could not be assessed easily. In addition to being noninvasive, gastric tonometry also identifies dysoxia in shock sooner than currently available monitors. This allows for more timely intervention with a subsequent improvement in prognosis in defined groups of patients. Tonometry data that suggest continued dysoxia despite intervention should signal clinicians to seek alternative diagnoses or to question the efficacy of current therapies, including antibiotics.

Equipments Used To Measure Blood Pressure
This invasive approach involves cannulating a peripheral artery. During each cardiac contraction, pressure generates mechanical motion within the catheter, transmitted through rigid, fluid-filled tubing to a transducer. This transducer converts mechanical motion into electrical signals displayed as waveforms on a monitor. An automatic flushing system prevents blood backflow. Due to the potential risk of unexpected arterial blood loss, this method is primarily used in intensive...
