Practically very unlikely, theoretically sure, when you're short of breath. The pectoralis muscles count as a accessory muscle of respiration.
Even trapezius and latissimus dorsi are accessory muscles of respiration, so on your back day you can have a harder time breathing when the diaphragm isn't enough.
