In the last 10 years, many clinical and experimental studies on this subject have been carried out, leading to the validation in mechanically ventilated patients of a few 'dynamic' parameters based on heart-lung interactions.
On the contrary, dynamic indices based on heart-lung interactions, such as pulse pressure variations (ΔPP), have repeatedly been found to reliably predict the response to fluids in mechanically ventilated patients.
Parameters based on heart and lung interactions are limited by their dependence on relatively large tidal volumes, arrhythmias, or the need for an arterial line [7].
"It's not based on heart rate.
Based on the heart-lung interplay during mechanical ventilation, fluid optimization has changed from CO optimization (maximization) to monitor dynamic parameters of volume responsiveness [ 5, 6].
At the time of sacrifice, a HF index based on relative heart weight (i.e. heart weight to body weight ratio), relative lung weight (i.e. lung weight to body weight ratio), left ventricular end-diastolic pressure, and ascites was calculated [39].
In most instances, infants placed on heart-lung machines need a blood transfusion.
In this study, the metabolic syndrome was defined using a combination of different definitions based on the modified American Heart Association AHAA)/National Heart, Lung, and Blood Institute (NHLBI) criteria (7) and the homeostasis model assessment of insulin resistance (HOMA-IR) index (8).
We took advantage of another project that had extensively genotyped genes thought to be related to chronic lung disease, based on our belief that heart disease and chronic lung disease share many pathways.
