Outcome Measures

Primary Outcomes (1)

  • Cardiac Output

    Cardiac output (in l/min) will be measured by transpulmonary thermodilution and arterial pulse contour analysis

    Study 1 day

Secondary Outcomes (2)

  • Transmural central venous pressure

    Study 1 day

  • Mean systemic filling pressure

    Study 1 day

Study Arms (2)

Low PEEP

EXPERIMENTAL

PEEP 5 cmH2O

Procedure: Physiological assesment

High PEEP

EXPERIMENTAL

PEEP 15 cmH2O

Procedure: Physiological assesment

Interventions

1. Arterial and mixed venous blood gas analysis. 2. Alveolar and physiologic dead space via volumetric capnometry, as well as carbon dioxide (CO2) production, end-tidal CO2 and mixed expired CO2 3. Respiratory system (Crs), chest wall (Ccw) and lung (Cl) compliance measurement via an end-inspiratory and end-expiratory pause. 4. Arterial blood pressure, central venous pressure (CVP), heart rate, cardiac output through the arterial pulse contour and transpulmonary thermodilution methods (PiCCO technology). Global end-diastolic volume, Intra-thoracic blood volume, Extravascular lung water will also be assessed. Respiratory hold maneuvers (at PEEP, and +10, +15 and +20 cmH2O) will be performed and CVP and cardiac output will be measured in the last 3 s of the 12 s inspiratory hold. Venous return curve will constructed and the zero-flow pressure recorded as the mean systemic filling pressure. 5. Urine flow in 1h and determination of the fractional excretion of sodium and creatinine.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • All patients aged 18 or older and with a recent (\<48h) diagnosis of ARDS, undergoing invasive mechanical ventilation and in whom, due to the hemodynamic instability, cardiac output monitoring with an Arterial pulse contour analysis and transpulmonary thermodilution system (PiCCO technology, Pulsion Medical Systems, Germany) will be considered necessary, will be considered for enrolment.

You may not qualify if:

  • Patients with barotrauma and with clinical evidence of intrinsic PEEP will be excluded.
