Does the Method Matter? Direct Fick Versus Thermodilution in the Haemodynamic Assessment of Pulmonary Hypertension

Key Points

• To evaluate the effectiveness of direct Fick compared to thermodilution in measuring cardiac output in pulmonary hypertension.
• Collected over 852 simultaneous thermodilution and direct Fick cardiac output measurements.
• Analyzed the data to assess the accuracy and reliability of both methods.
• Findings highlight significant differences in outcome measurements between the two techniques.
• Thermodilution showed varying effectiveness depending on specific patient conditions.
