The weaning status for many of these patients improved when caregivers paid more attention to managing their cardiac conditions. Anemia, a blood related problem, is frequently associated as a barrier to weaning. The anemic patient does not have enough hemoglobin in the blood to transport needed oxygen. Most RCPs do pretty well on assessing this and identifying it as a problem. On the other hand, few of us will ever comment on the fluid status of a patient.
Fluid overload can manifest itself by reducing both lung and chest wall compliance.
That does not mean we should start checking IV rates, emptying urinals or determining dialysis schedules. But it is crucial for us to recognize that dialysis schedules may directly impact the success of our weaning. Here is an interesting fact you can use to wow nurses. Studies have shown mechanical ventilation can cause elevations in plasma antidiuretic hormone and a reduction in atrial natriuretic hormone. High-calorie diets can translate to higher CO 2 production metabolically.
