First Claim
Patent Images
1. A method in a computer system for predicting the need for giving a patient a blood transfusion, the method comprising:
- controlling a meter to measure vital signs, said vital signs being one or more chosen from the group of;
hemoglobin (“
HgB”
), oxygen saturation (“
SpO2”
), blood perfusion, total hemoglobin (“
SpHb”
), oxygen content (“
SpOC”
), carboxyhemoglobin (“
SpCO”
), methemoglobin (“
SpMet”
), sublingual partial pressure of carbon dioxide (“
SlCO2”
), hemoglobin (“
Hb”
), pulse variability index (“
PVI”
), perfusion index (“
PI”
), near infra-red spectroscopy (“
NIRS”
), impedance cardiography, thromboelastography, proteomics, cytokines, proteins, biomarkers, blood pressure (“
BP”
), heart rate (“
HR”
), body temperature, and respiratory rate;
communicating said vital signs to a control unit;
analyzing two or more of said measured vital signs using a control algorithm to determine whether said patient is in need of said blood transfusion; and
when it is determined that said patient is in need of said blood transfusion, controlling a graphic user interface that is in communication with said control unit to provide communications to a user indicating that said patient is in need of said blood transfusion.

Abstract
A device and control software and system capable of accepting patient vital sign readings from an oximeter and applying a predetermined decision algorithm that incorporates unique combinations of vital signs and will allow the care giver to continuously monitor and have continuous feedback regarding certain patient vital functions, body trauma status, and immediate treatment needs, such as the patient'"'"'s likelihood of the onset of shock and the advisability of introducing blood or blood products to the patient.
