SpHb®Noninvasive and Continuous
Real-time visibility to changes, or lack of changes, in haemoglobin between invasive blood samples
Limitations of Traditional Methods Alone
Without SpHb, clinicians are often limited to invasive blood samples, which provide intermittent and delayed laboratory haemoglobin results
Value of SpHb Monitoring
SpHb can be used in conjunction with traditional laboratory methods to obtain real-time visibility to changes, or lack of changes, in haemoglobin between invasive blood samples
SpHb monitoring may provide additional insight between invasive blood samples when:
- > The SpHb trend is stable and the clinician may otherwise think haemoglobin is dropping
- > The SpHb trend is rising and the clinician may otherwise think haemoglobin is not rising fast enough
- > The SpHb trend is dropping and the clinician may otherwise think haemoglobin is stable
SpHb was retrospectively obtained for the surgical case shown below, in which clinicians could not assess the haemoglobin trend between invasive blood samples during the procedure1
Studies have shown that SpHb may help clinicians reduce blood transfusions in both low and high blood loss surgeries2,3
- > A prospective cohort study of 106 neurosurgical patients found that adding SpHb monitoring to standard-of-care blood management resulted in decreased blood utilisation in high-blood-loss neurosurgery, while also facilitating earlier transfusions3*
Clinical decisions regarding red blood cell transfusions should be based on the clinician's judgment considering among other factors: patient condition, continuous SpHb monitoring, and laboratory diagnostic tests using blood samples.
* The blood sampling technique was the same for patients in both the control and the test group. Arterial blood was drawn from a 20 gauge radial artery cannula into 2mL ethylenediaminetetraacetic acid collection tubes, thoroughly mixed then sent immediately to the central lab for analysis by a haematology analyzer. The reference laboratory device used for haemoglobin measurements in the study was a Coulter GENS Hematology Analyzer.

Noninvasive and Continuous Haemoglobin (SpHb) Monitoring
SpHb monitoring is not intended to replace laboratory blood testing. Blood samples should be analysed by laboratory instruments prior to clinical decision making.
For professional use. See instructions for use for full prescribing information, including indications, contraindications, warnings, and precautions.
