Acute Respiratory Distress Syndrome
Can we quantify pulmonary edema?
Would it not be great if you could quantify pulmonary edema in complex indications such as ARDS? The parameter Extra vascular lung water (EVLW) reflects the interstitial, intracellular, alveolar, and lymphatic fluid in the lungs.
Thus, for diagnosis and management of ARDS, EVLW is a valuable tool and helps to base decisions on facts not on feelings.
Clinical issue: Chest x-rays do not reliably reflect the level of pulmonary oedema.
Severe pulmonary edema
Moderate pulmonary edema
No pulmonary edema
The quality of x-ray is influenced by many factors:
Accurate patient position
"PiCCO provides... relevant information on preload responsiveness indexes, cardiac output and extravascular lung water... PiCCO thus allow clinicians to take rapidly appropriate decisions..., to continue and to stop fluid administration”.
“In the PiCCO monitor I have one machine that can safely provide me with all the information needed ....I am able to measure the effects of my therapeutic interventions on extravascular lung water – all at a per patient cost only slightly greater than a standard arterial line.”
