Critical Care Monitoring

Continuous BP monitoring in acute patients
  • Patients in critical care settings are often unstable and need close monitoring
  • Most of those patients are monitored with an intermittent cuff, which misses critical hypotension events.
  • Studies demonstrated that hypotension contributes to the development of MI (myocardial injury) and AKI (acute kidney injury)
  • Sensifree’s continuous and non-invasive BP monitoring device allows timely
    hypotension identification and early intervention

Patients admitted to hospital’s critical care units – operating rooms, post anesthesia care units and intensive care units, are often unstable and require close vital signs monitoring. Continuous BP monitoring would be highly desired for all these patients, however currently available methods for this limit continuous monitoring to a small percentage of the cases.

 

A number of large studies have shown that episodes of low blood pressure result in an increased risk of mortality, acute kidney injury (AKI) and myocardial injury (MI), both in the ICU1,2 and during surgical operations3,4,5,6. Risk grows with cumulative time under certain MAP levels, thus continuous monitoring is required to effectively mitigate this risk.

 

There is a high motivation to extend continuous BP monitoring to larger groups of patients. MI is the leading cause of 30 days post-operative mortality7,8, itself the 3rd leading cause of death in the US9.

 

Sensifree offers a solution for continuous, non-invasive BP monitoring, based on the ubiquitous fingertip optical sensor, typically used for SpO2 monitoring. This affordable, easy to use solution is a real paradigm shift in BP monitoring, bringing a new standard of care in acute patient management.
