The INVOS® System - a safe and effective vital sign.

The INVOS® Cerebral/Somatic Oximeter is a noninvasive, safe and effective oxygen monitor for adults, children, infants and neonates in any clinical setting. Doctors who believe their patient may be at risk for oxygenation problems may use the INVOS® System to enhance the patient's safety and outcome.

The INVOS® System uses IN Vivo Optical Spectroscopy to provide real-time monitoring of changes in regional oxygen saturation (rSO2) of blood in the brain or other body tissues beneath the sensor. The INVOS® System is unique in that it allows clinicians to measure site-specific oxygen levels, rather than requiring them to infer that data from systemic, whole body measures such as blood pressure and pulse oximetry.

Available in either two or four data channels, clinicians can conveniently monitor multiple brain and body areas that interest them.

Today's 6th-generationtech1 INVOS® System is the only commercially available system in the United States to provide four-channel oximetry for simultaneous cerebral and somatic monitoring.

 

The INVOS® System consists of:
  • The monitor
  • One or two preamplifiers
  • Reusable sensor cables
  • Disposable sensors (available in adult, pediatric, infant/neonatal)

The entire system is comparable in weight and size to a transport monitor, meaning that space at the bedside or in the operating room is not compromised. For added convenience, it may also be attached to a swivel arm or rolling stand for portability throughout the hospital. User-friendly too, the INVOS® System comes pre-calibrated and ready to use in as little as 30 seconds.

Patient indicator reflects the software program and sensor type being used (Adult, Pediatric or Infant). rSO2 trend graph: Provides a visual graph of the cerebral-somatic (body) rSO2 values over time to highlight patient status and responses to care. Real-time rSO2 index provides clinicians the patient's real-time oxygen saturation for up to four site-specific sensors. It is continuously displayed on-screen to provide immediate warning when values drop below threshold levels.

Percent change from baseline number is automatically calculated and continuously displayed so clinicians can see the relative change between a patient's baseline and his real-time rSO2. Drops of 20-25% are considered cause for concern and intervention.

Alarm bell icon and graph lines denotes pre-selected upper and lower rSO2 thresholds for each patient. Status messages warn of pending problems and/or provide troubleshooting prompts. Signal strength indicator reflects whether there is sufficient signal to generate a valid rSO2 value. If not, a troubleshooting prompt will be displayed in place of the number.

Power indicators reflect the battery power charge remaining; system may operate from a standard A/C Mains wall outlet or via battery. rSO2 trend graph: Provides a visual graph of the cerebral-somatic (body) rSO2 values over time to highlight patient status and responses to care. Baseline rSO2 is the blood oxygen saturation level at the outset of monitoring to which subsequent changes will be compared. It reflects the impact of morbidities and patient-unique physiology on oxygenation levels at the start of the procedure or treatment, allowing the patient to serve as his/her own control.

The INVOS® Cerebral/Somatic Oximeter provides oxygenation/perfusion data from vascular beds that represent opposite poles of regional circulation. The cerebral circulation is a high-flow, high extraction system, whereas the peripheral flow is variable with low extraction. Cerebral/somatic monitoring is a powerful combination to detect both early (peripheral) and later (cerebral) indicators of oxygen changes associated with shock or other perfusion abnormalities.
Four-channel, cerebral and somatic monitoring on an infant.

Simultaneous rSO2 monitoring of cerebral and somatic tissue is being adopted most rapidly by pediatric and neonatal critical care clinicians. This data is used to:
  • Monitor the stability of cerebral and peripheral circulations in a noninvasive, real-time way.
  • Leverage associations between cerebral and peripheral circulations to better manage care; i.e. whether the periphery appears to be shunting blood flow to preserve the brain.
  • Determine whether vascular beds surrounding vital organ areas are adequately perfused.
  • More closely identify and manage regional oxygenation issues in the OR, PICU, NICU and cardiac cath lab.
  • Obtain objective data noninvasively for decision making.
