Cardiopulmonary Bypass Surgery
Conditions
Keywords
cardiopulmonary bypass
Brief summary
A prospective single-center randomized controlled trial to determine if guided hemodynamic management with the Acumen HPI technology in the OR and ICU can reduce the mean duration of hypotension in cardiac surgery patients requiring cardiopulmonary bypass.
Interventions
The AcumenTM HPI Feature Software provides the clinician with physiological insight into a patient's likelihood of trending toward a hypotensive event. The AcumenTM HPI Feature Software suite is enabled by the minimally invasive Acumen IQ sensor.

Eligibility
Inclusion criteria
1. Subjects who are at least 18 years of age 2. Subjects who have signed the Informed Consent Form 3. Subjects with planned pressure monitoring with an arterial line 4. Subjects with planned sternotomy 5. Subjects with planned general anesthesia 6. Subjects who have ASA Physical Status ≤ 4 7. Subjects with planned cerebral oximetry monitoring 8. Subjects with planned overnight hospitalization 9. Subjects with planned cardiopulmonary bypass (CPB) "on-pump" surgery
Exclusion criteria
1. Subjects with a physical site area too limited for proper Sensor placement 2. Subjects with contraindications for Arterial Line Placement; 3. Subjects participating in another (interventional) study 4. Subjects in whom an intraoperative MAP target will be \< 65 mmHg 5. Subjects with pre-op or pre-pump or post-pump LVEF \< 15% 6. Subjects requiring heart transplant 7. Subjects with pre-existing circulatory support devices or planned circulatory support devices post-bypass 8. Subjects requiring emergency surgery 9. Subjects with known or identified severe PAH (defined as pulmonary systolic pressure\> 70mmHg or mean pressures \> 55mmHg) as determined by a pre-operative echo or intraoperative Swan-Ganz 10. Subjects with cardiovascular instability in the operating room necessitating the need to go back on bypass for a subsequent run
