Non-invasive Carbon Dioxide Monitoring and Endoscopic Retrograde Cholangiopancreatography Patients
Keywords
Abstract
Description
Many patients become hypoxic during endoscopic retrograde cholangiopancreatography (ERCP). Following induced sedation, hypoxia or hypercapnia may follow . Monitoring the CO2 level during respiration (capnography) is non-invasive, easy to do, relatively inexpensive, and has been studied extensively . End-tidal carbon dioxide is the level of CO2 released at the end of an exhaled breath . Capnography provides information about ventilation, perfusion and metabolism . Capnography devices are configured as either side stream or mainstream. Side stream devices can monitor both intubated and non-intubated patients, while mainstream devices are most often limited to intubated patients .
The Dual guard (made in China) sets a standard in endoscopic practices; it incorporates an endoscopy bite block with oxygen delivery and CO2 monitoring for use in upper endoscopy procedures through to recovery . It improves patient safety and meets current guidelines for consciously sedated patients. The Comfort Rest Bite Block fits securely in the mouth, protecting both endoscope and patients' teeth. Simultaneous oral and nasal O2 delivery and CO2 sampling for patients undergoing upper GI endoscopy, in either a lateral or supine position. Arterial blood gas test results show the patient's acid-base balance, which is measured by the hydrogen ion concentration present in the blood, its oxygen saturation, partial pressure of oxygen (PaO2), partial pressure of carbon dioxide (PaCO2), concentration of bicarbonate (HCO3), base excess and base deficit . Itcan provide information about a surgical patient's physiological state, oxygenation, ventilation and indicate the primary source of a disturbance (ie, respiratory or metabolic) in homeostasis .
