Can anyone predict what would happen to a baby's tidal volume of the phrenic nerves, if the spinal nerves to the intercostal muscles and if the nerves supplying stretch receptors in the lungs were damaged?

The phrenic nerves activate the diaphragm (the primary muscle of breathing). Damage of these nerves could lead to paralysis of the diaphragm resultimg in the use of accessory muscles (such as the intercostals). Stretch receptors (also known as the Herring-Breuer reflex) prevent the lung from excessive expansion.

The intercostals should just help with forced expiration. Normal expiration is passive. If the phrenics are still intact I would say the tidal volumes should be little affected.
Is this hypothetical? How did the J receptors and spinal nerves get damaged?

Without the phrenic nerves, the diaphragm isn't going to work, so tidal volume would be nothing. Get that baby on a ventilator!

physiology relating question. Tidal volume would be low. It means the baby would be exposed to low levels of oxygen ultimately leading to asphixia due to intecoastal muscle spasm.

If everything was damaged I think you would have no tidal volume and too you need to expand your lungs by breathing so if these nerves are damaged then there would be no stimulation to breath in and out
