A

Hemovac is a surgical drain inserted by a surgeon that geerates negative pressure. Can be inserted superficially, in an organ, or a duct.

27
Q

What is a chest tube?

A

Tube instered into the pleural space to neutralize intrapleural pressure after PIP increase from tension pneumothorax, Hemothorax etc.

28
Q

What are the three letter categories in pacemaker coding?
