Poland, WrocławRe the ruling out of lung pathology like blebs or bullae: again this is speculation, not suggesting that you need to run out and do this, but you would need a high-resolution CT scan for that.
Good to hear about the negative TCD with bubbles - it's likely that you can rule out shunting then, which would make you being a "bubbler" something of a moot point and obviate the need for further study like transthoracic echocardiography to determine shunt morphology.
Re saturation, if you're talking about pulse oximetry, a low reading following a dive would be an alarming sign, especially in the setting of decompression sickness. A normal reading on room air doesn't really rule out anything but significant respiratory depression or pulmonary pathology.
Exactly where in Europe are you?
