Why the study?
Does intrathoracic blood volume monitoring better reflect preload dependency of cardiac output compared to cardiac filling pressures in hypovolaemic patients after cardiac surgery?
Population
14 hypovolaemic adult patients after cardiac surgery
Design
Cohort
Follow-up
1 hour steady-state period after volume loading

Intrathoracic blood volume may better track preload dependency than CVP or PAOP after cardiac surgery; hypothesis-generating and requires prospective validation.
Does intrathoracic blood volume monitoring better reflect preload dependency of cardiac output compared to cardiac filling pressures in hypovolaemic patients after cardiac surgery?
Intrathoracic blood volume reflects preload dependency of cardiac output more accurately than traditional cardiac filling pressures in postoperative cardiac surgery patients.
