SpHb®
Continuous SpHb provides real-time visibility to changes, or lack of changes, in haemoglobin between invasive blood samples
Home / Total Haemoglobin (SpHb®)
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 trend 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
Clinical Case
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
SpHb Utility
Studies have shown that SpHb may help clinicians reduce blood transfusions in both low and high blood loss surgeries2,3
A randomised trial of 327 patients undergoing elective orthopaedic surgery, conducted at Massachusetts General Hospital (MGH), found that the use of continuous, noninvasive haemoglobin monitoring reduced the rate of transfusions when compared to standard care without continuous, noninvasive haemoglobin monitoring2
% of Patients Receiving RBC Transfusion2
A comparative study of 237 hip surgery patients with and without continuous SpHb monitoring demonstrated that real-time SpHb monitoring led to a financial savings of €20.83 per patient, amounting to an estimated savings of €1.736M nationally3
Savings Per Patient in Euros
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.
SpHb Supports Clinicians in Improving Patient Outcomes
A single-center quality program involving 18,716 patients, conducted in Limoges, France, demonstrated that monitoring with SpHb and PVi integrated in a vascular filling algorithm was associated with earlier transfusion and reduced 30- and 90-day mortality by 33% and 29%, respectively on a whole hospital scale4

SpHb monitoring is not intended to replace laboratory blood testing. Blood samples should be analysed by laboratory instruments prior to clinical decision making.
