INVOS™ technology overview pt 8: How can NIRS be interpreted?

Dr. Ronald Bronicki, Professor of Pediatrics at Baylor College of Medicine, Section of Critical Care Medicine & Cardiology at Texas Children’s Hospital, presents how regional oximetry represents the balance between oxygen delivery and demand as well as the clinical factors that may influence regional tissue oxygenation. 

INVOS™ technology overview pt 7: How is the algorithm developed for the pediatric population?

Eli Kuhlmann, Sr. Research Manager at Medtronic, describes how the INVOS™ system pediatric algorithm was developed in order to account for factors impacting regional oximetry measurements in pediatric patients. The INVOS™ monitoring system should not be used as the sole basis for diagnosis or therapy and is intended only as an adjunct in patient assessment.

INVOS™ technology overview pt 6: What are the principles of NIRS oximetry?

Ronald Bronicki, Professor of Pediatrics at Baylor College of Medicine, Section of Critical Care Medicine & Cardiology at Texas Children’s Hospital, teaches us how NIRS uses near infrared light to monitor the percentage of oxygenated hemoglobin in the tissue 2-3 cm beneath the oximeter sensor.

INVOS™ technology overview pt 5: What are the system design considerations?

Eli Kuhlmann, Sr. Research Manager at Medtronic, reviews the design elements in the INVOS™ system that enhance its regional oximetry monitoring performance. The INVOS™ monitoring system should not be used as the sole basis for diagnosis or therapy and is intended only as an adjunct in patient assessment.

INVOS™ technology overview pt 4: How does the system determine optimal spacing?

Eli Kuhlmann, Sr. Research Manager at Medtronic, demonstrates how the sensor spacing on the INVOS™ sensor maximizes the detection of the tissue of interest while suppressing the superficial tissue signal. The INVOS™ monitoring system should not be used as the sole basis for diagnosis or therapy and is intended only as an adjunct in patient assessment.

INVOS™ technology overview pt 3:What are the advantages of NIRS oximetry?

Dr. Ronald Bronicki, Professor of Pediatrics at Baylor College of Medicine, Section of Critical Care Medicine & Cardiology at Texas Children’s Hospital, discusses the advantages of NIRS oximetry compared to traditional approaches of monitoring cardiovascular function and tissue oxygenation. 

INVOS™ technology overview pt 2: How does the monitor localize oxygen saturation measurement?

Eli Kuhlmann, Sr. Research Manager at Medtronic, reviews how the INVOS™ monitor isolates the near infrared signal from the tissue of interest and prevents contamination from superficial tissue. The INVOS™ monitoring system should not be used as the sole basis for diagnosis or therapy and is intended only as an adjunct in patient assessment.

INVOS™ technology overview pt 1: How does spectroscopy work?

Eli Kuhlmann, Sr. Research Manager at Medtronic, teaches us how near infrared spectroscopy (NIRS) measures the concentration of hemoglobin in blood.

NIRS and regional oximetry in neonatology, Pt 17: How can the INVOS™ monitor be used in real-time assessments?

Terri Marin shares how the INVOS™ monitor can be used in real-time assessments during our final segment in this series. Regional oximetry is an adjunctive technology that should not be used as the sole basis for diagnosis or clinical decision-making.

NIRS and regional oximetry in neonatology, Pt 16: How does the INVOS™ monitor work?

How does the INVOS™ monitor work? Terri Marin, PhD, NNP-BC, FAANP at Augusta University, dives into the subject. Regional oximetry is a adjunctive technology that should not be used as the sole basis for diagnosis or clinical decision-making.
