Abstract:
Vascular access for catheterization of a pediatric patient on extracorporeal membrane oxygenation (ECMO) was facilitated by adding an accessory limb to the ECMO circuit. This limb was terminated with a hemostatic valve allowing insertion of a catheter. Changes in support parameters compensated for the change in the effective diameter of the ECMO cannula on insertion of the catheter. This method can overcome difficulties in obtaining vascular access for patients on ECMO.

Tracheostomy
A tracheostomy is a surgically created opening (stoma) in the anterior part of the trachea. It is used to establish a patient airway, bypass an upper airway obstruction, simplify the removal of secretions, permit long-term...

Venturi Mask
The Venturi mask, named after the Venturi effect, is designed to deliver precise oxygen concentrations. It consists of a large tube with an oxygen inlet that narrows down, causing a pressure drop that pulls air in through adjustable side ports. The mask is a lightweight,...
