Hark! Within the theatre of the heart, where surgeons wield both steel and purpose, there lies a most curious contraption — the cardiotomy sucker. What noble task it claims: to rescue blood lost to the field! Yet, beneath its virtuous guise, what mischief brews within its swirling depths? This discourse shall unveil the hidden torment of the crimson tide — where red cells are tossed and tumbled, where bubbles do conspire, and where science itself doth scratch its head in wonder. Are we saviours of the sanguine stream, or unwitting architects of its undoing? Gather ye, and we shall muse upon the mysteries of suction, the unseen dramas within the line, and the delicate art of keeping blood both living and loyal.
