Could a kidney problems lead to lung problems?

[swansonplace]

Just curious if a patient with kidney problems could have lung problems, or breathing problems?

My thinking was that with kidney issues, there could be less circulating blood volume -> less cardiac output -> less blood going to lungs -> respiratory difficulty

Is this case probable?

I was wondering what could cause a person with kidney issues to have respiratory difficulty

Kidney issues, there could be less circulating blood volume -> (hypovolemic)less blood going into heart -> less oxygenated blood -> respiratory difficulty

Do I understand correctly that this case is very rare.

The kidney issues that have respiratory difficulty is most likely going to be due to fluid volume excess, fluid in the lungs, CHF.

Correction on flow:

Kidney issues, there could be less circulating blood volume -> (hypovolemic)less blood going into heart -> less oxygenated blood -> Respirations would go up

Reference: Hurst Review Fluid Volume Deficit: Hypovolemia

I will going to review a couple of the systems that I misunderstood.

Kidneys and the respiratory system do work together. ADH is produced in the hypothalamus, but acts on the kidneys to increase blood volume. An excess of fluids can cause problems like pulmonary edema. Kidneys also retain or excrete Bicarbonate. If a person becomes acidic or alkolytic it can effect their breathing to compensate for the pH imbalance.

Thank You.

Students often forget that kidneys have more than one function. The pump out substances that affect more than fluid volume.

People with chronic renal failure have less erythropoietin, the hormone that makes the marrow churn out red blood cells, so they are often very anemic, and that can make people short of breath regardless of fluid status. Anemia alone will not make lungs heavy and wet, but they can make you feel as if your breathing isn't easy. If you have ever been to altitude >12,000 feet from sea level, you can feel what that's like.

Hypovolemia can result in decreased blood being pumped, although compensatory mechanisms will mask this effect unless very serious. I think your referencing Hurst is incomplete; I am sure that chapter talks about a great deal more than just hypovolemia, and I am also sure that they tell you in the renal chapter that ....

Renal problems rarely result in hypovolemia.

Hypovolemia alone will not result in increased respiratory rate.

Kidney issues can also lead to ARDS (Acute Respiratory Distress Syndrome). Is this what you are referring to? This is a result form excess fluid volume though usually due to sepsis.
