After the basilic vein became the brachial vein, you drifted north for quite some time until it turned into the axillary vein. That became the subclavian vein, and this led to the superior vena cava, which has now taken you into the right atrium of the heart. You are currently at the entrance to the right ventricle of the heart, the tricuspid valve.

However, if you survive, you will enter the lungs, and will have the opportunity to refill your oxygen tanks, which are by now somewhat low.
