By Megan Murdock Krischke, contributor. Critical-care nursing, or intensive-care-unit ICU nursing, is a specialty that requires focus and stamina. We would like to hear from you. Many factors can affect the requirements for oxygen and subsequently S VO2 Table Because a critically ill patient is in a dynamic state with rapidly changing oxygen demand and oxygen consumption, S VO2 must be viewed in the light of these changing determinants and considered an index of oxygen balance.

S VO2 monitoring is used in critically ill patients for earlier detection of oxygenation instability than that obtained through traditional PA monitoring. It does not include blood from the IVC and coronary sinus. This difference is in part because of a redistribution of blood flow caused by the various pathophysiologies.

A fiberoptic central venous CV or PA catheter contains two fiberoptic filaments that exit at the distal lumen. One filament serves as a sending fiber for the emission of light; the other serves as a receiving fiber for the light reflected back from the blood in the vessel Fig.

A, Small French size for pediatric applications. B, Central venous catheter. C, Pulmonary artery catheter. The optic module houses the light-emitting diodes LEDs , which transmit various wavelengths of light, and a photodetector, which receives light back. The light wavelengths are shone through a blood sample. Desaturated hemoglobins, saturated hemoglobins oxyhemoglobin , and dyshemoglobins carboxyhemoglobin, methemoglobin have different light absorption characteristics.

The ratio of hemoglobin to oxyhemoglobin is determined and reported as a percentage value. This module should not be disconnected.

An oximeter computer, which can be a stand-alone unit or a module for a bedside monitoring system, has a microprocessor that converts the light information from the optic module into an electrical display, updated every few seconds for continuous monitoring. This information is displayed as a continuous graphic trend, a numeric display, or both, depending on the manufacturer.

Proper calibration of the monitor and catheter ensures accuracy of venous saturation values. The two types of calibration are in vitro, in which the catheter and optics module are calibrated before insertion; and in vivo, where the venous saturation value is compared with a laboratory co-oximeter value from a blood sample. Follow manufacturer recommendations for performing calibration procedures. Daily in vivo calibrations are recommended.

In addition, proper blood sampling techniques from the distal port of the PA catheter are necessary for ensuring accurate values for calibration. Rationale: For information to be the most appropriate, assessment of the level of patient and family understanding of need for ScVO2 or S VO2 monitoring is important. Rationale: Explanation of the procedure to the patient and family helps to alleviate fears and concerns.

Additional monitors may produce increased anxiety in the patient and family. Bishop, MH, et al, Prospective, randomized trial of survivor values of cardiac index, oxygen delivery, and oxygen consumption as resuscitation endpoints in severe trauma.

The reading, obtained with standard pulse oximetry, uses a light sensor that contains two sources of light red and infrared absorbed by hemoglobin and transmitted through tissues to a photodetector. The infrared light is absorbed by the oxyhemoglobin, and the red light is absorbed by the reduced hemoglobin.

The amount and type of light transmitted through the tissue is converted to a digital value that represents the percentage of hemoglobin saturated with oxygen Fig. FIGURE A sensor device that contains a light source and a photodetector is placed around a pulsating arteriolar bed, such as the finger, great toe, nose, or earlobe. Red and infrared w avelengths of light are used to determine arterial saturation. Patient variables include the following: Hemoglobin level Presence of dyshemoglobinemias i.

Oxygen is more readily released to the tissues when pH is decreased acidosis , body temperature is increased, PaCO2 , is increased, and 2,3-diphosphoglycerate levels a by-product of glucose metabolism that facilitates the dissociation of oxygen from the hemoglobin molecule to tissue are increased decreased oxygen affinity. When hemoglobin has greater affinity for oxygen, less is available to the tissues increased oxygen affinity.

Conditions such as increased pH alkalosis , decreased temperature, decreased PaCO2 , and decreased 2,3- diphosphoglycerate as found in stored blood products increase oxygen binding to the hemoglobin and limit its release to the tissue.

In some patients, a difference is seen in SpO2 values at rest compared with values during activity, such as ambulation or positioning. The true measure of ventilation is determination of the PaCO2 in arterial blood.

Use of SpO2 in a patient with obstructive pulmonary disease may result in erroneous clinical assessments of condition. The normal baseline SpO2 for a patient with known severe restrictive disease and more definitive methods of determination of the effectiveness of ventilation must be assessed before consideration of interventions that enhance oxygenation.

The impact of dark nail polish, such as blue, green, brown, or black colors,4,5,11,17 has been reported to limit the transmission of light and thus impact the SpO2 , although a recent study showed that fingernail polish does not cause a clinically significant change in the pulse oximeter readings in healthy individuals. Pulse oximetry has not been shown to be affected by the presence of an elevated bilirubin.

Standard pulse oximetry equipment should never be used in suspected cases of carbon monoxide exposure. However, recent technology advancements in pulse oximetry have included the introduction of a monitor system that uses up to 12 wavelengths with a digit-based pulse oximeter sensor and that allows for measurement estimates of certain, dyshemoglobinemias i. One study found more frequent differences between the SpO2 and SaO2 in black patients when compared with lighter skinned patients10 ; another study did not find a significant difference.

Dyes include methylene blue, indigo carmine, indocyanine green, and fluorescein. Rationale: This explanation informs the patient of the purpose of monitoring, enhances patient cooperation, and decreases patient anxiety. Rationale: This explanation decreases patient and family anxiety over the constant variability of the values. Rationale: This explanation prepares the patient and family for other possible diagnostic tests of oxygenation e. Rationale: This information facilitates patient cooperation in maintaining sensor placement.

Demonstrate the alarm system, alerting the patient and family to the possibility of alarms, including causes of false alarms. Rationale: An understanding of the need to move the sensor routinely assists in patient understanding of the frequency of sensor movement. Anticipation of conditions in which hypoxia could be present allows earlier intervention before unfavorable outcomes occur.

The w indow s for the light source and photodetector must be placed directly opposite each other on each side of the arteriolar bed to ensure accuracy of SpO2 measurements. Choice of the correct size of the sensor helps decrease the incidence of excess ambient light interference and optical shunting.
