Q. Maltese with heart murmur gets better oxygenation standing than at rest. 8 y.o. Fem. Echocardiogram scheduled. On 1ml lasix twice daily and 1/2 valium
DR. CHRISTIE LONG, D.V.M., C.V.A.
A. I'm not quite sure what your question is. If she's oxygenating better while standing it's likely that she's got fluid in her lungs or in her chest cavity and when she's standing the fluid repositions such that she can get better expansion of her lungs. You should call your vet to discuss your observations and determine if the Lasix dosage needs to be adjusted, or if chest x-rays need to be taken in order to determine if fluid is accumulating faster than it was previously.
