Acute Respiratory Distress Syndrome (ARDS) is an acute lung injury which may stem from multiple causes (direct injury, sepsis, pneumonia) resulting in inflammation in the lungs, which increases permeability to fluids. A non-cardiogenic pulmonary edema is present, and mechanical ventilation is usually required.1
ARDS patients may present with competing fluid management goals – fluid resuscitation for perfusion vs. fluid restriction for lung function2. Due to patient positioning, changing lung mechanics and use of PEEP, Pulse Pressure Variation (PPV) and Stroke Volume Variation (SVV) may not adequately judge fluid responsiveness.
Why Are ARDS Patients Likely to Benefit From Cheetah Technology?
Cheetah’s 100% noninvasive hemodynamic data provides the clinician the tools to manage perfusion. Key parameters such as Stroke Volume and Cardiac Output, gives the clinician the ability to directly measure changes in Stroke Volume Index to gauge fluid responsiveness.
The continuous hemodynamic profile from Cheetah is available even in the prone position and enables clinicians to manage drug and fluid administration. Continuous monitoring is a challenge for other technologies given changing lung mechanics and the common use of PEEP.
Early fluid management guided by Cheetah’s technology is important, especially during different phases of ARDS – early adequate initial fluid resuscitation vs later conservative fluid management.
