Patient monitoring by means of CNAP™

 
With CNAP™ you will see dangerous blood pressure decreases immediately – non-invasively

 
Hypotension is the most common complication in the operating theatre and PACU (1) – current standards of blood pressure measurement do not provide sufficient monitoring.
 
Hypotension and the oxygen deficiency connected with it is a common reason for perioperative complications and postoperative mortality:

  • 56% of cardiac arrests during surgery are preceded by hypotension (2)
  • Every single minute of hypotension raises 1-year postsurgical mortality risk by 3% (3)

For early diagnosis and counteracting hypotension efficiently, generally neither upper arm NBP nor intra-arterial measurement are recommended.

Upper arm NBP measurement is intermittent and in short intervals painful for the patient (4) and can therefore not avoid the risk of hypotension:

  • 44% of hoyptensive episodes are missed or recognised too late (5)
  • The duration of such episodes is thus mostly underestimated (5)

Intra-arterial measurement is not used in 82% of the cases (6):

  • Painful for the patient
  • Expensive, time-consuming and risky
  • Only a high risk (ASA 4) and the need for additional blood values (e.g. blood gases) justify invasive measurement
