Potential advantages and disadvantages of echocardiography versus invasive monitoring.
|Echocardiography||Invasive haemodynamic monitoring|
|Invasiveness||TTE noninvasive TEE semi-invasive||PAC invasive arterial waveform analysis semi-invasive|
|Portability||Scanners easily moved to patient||Generally not portable|
|Use in acute care||Yes, also documented for ED||No|
|User dependent||Very user dependent||Less user dependent, some methods require calibration|
|PAC: pulmonary artery catheter; TTE: transthoracic echocardiography; TEE: transoesophageal echocardiography.|
