Heart puncture, this isn't Liu Banxia's first time. Last time, he performed a pericardial puncture, and it scared him enough to break out in a cold sweat.
This time, it's a right ventricular puncture, meant to siphon the foamy blood from the right ventricle to allow the heart to function normally.
The foamy blood resulted when air entered the bloodstream, reached the right ventricle, and was beaten into bubbles by the strong contractions of the myocardium.
His judgment is based on the patient's thoracic injury, which could have already damaged the pulmonary vein, allowing air to gradually get to the right ventricle.
By the time they reached the emergency center, the accumulated air was too much, causing the patient's current symptoms.
But performing a puncture on the right ventricle isn't necessarily easier than a pericardial puncture. There's no such thing as an easy puncture on the heart.
