a. fat
When weaning a patient from a ventilator, it is often helpful to provide a formula that has decreased levels of fat as compared to a standard polymeric formula. This is because high levels of fat in the formula can increase the workload on the patient’s respiratory system, potentially making it harder for them to wean off the ventilator. By decreasing the fat content, the patient’s body can focus on recovering and transitioning to regular oral intake without the added burden of digesting and metabolizing excessive fat.
I hope this is helpful.
