Pediatric ventricular assist devices (VADs) are being developed to treat heart failure in children. This innovative PediaFlow VAD uses magnetic levitation to minimize blood trauma and thrombosis risk.

Area of Science:

  • Biomedical Engineering
  • Pediatric Cardiology
  • Medical Device Development

Background:

  • Limited treatment options exist for pediatric ventricular failure.
  • Congenital and acquired heart diseases pose significant risks to children.
  • Development of a pediatric ventricular assist device (VAD) is crucial.

Purpose of the Study:

  • To develop a reliable and biocompatible VAD for chronic support in pediatric patients.
  • To address the unique needs of children weighing 3-15 kg (birth to 2 years).
  • To minimize blood trauma and thrombosis risk in pediatric VADs.

Main Methods:

  • Development of the PediaFlow VAD, a miniature mixed-flow turbodynamic pump.
  • Utilizing magnetic levitation technology for pump operation.
  • Collaboration between academic institutions and industry partners.

Main Results:

Oxygen Delivering System II: Venturi Mask and Transtracheal Oxygen

Oxygen therapy is a pivotal aspect of medical care, particularly for patients with respiratory ailments. Two prominent oxygen-delivering systems include the Venturi mask and the transtracheal oxygen catheter.
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,...

Oxygen Delivering System III: Tracheostomy and T-piece

Oxygen delivery is critical in clinical care, especially for patients with respiratory disorders or those undergoing surgical procedures. Various systems, such as tracheostomy and the T-piece, deliver oxygen to the lungs, ensuring adequate arterial oxygenation.
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...

Mechanical Ventilation I: Indication and Settings

Mechanical ventilation is a life-saving technique for managing acute respiratory failure and other respiratory complications. The process involves using a machine known as a ventilator to supply oxygen to the lungs and assist in removing carbon dioxide. It serves as a bridge to long-term mechanical ventilation or a temporary measure until ventilatory support is discontinued. The ventilator can maintain this function for a prolonged period, providing critical support for patients until they can...

Mechanical Ventilation II: Invasive Ventilation

Ventilators are essential medical equipment used to aid patients with respiratory difficulties. Their primary function is to assist or replace spontaneous breathing by providing mechanical ventilation. There are two general classes of mechanical ventilators: negative-pressure and positive-pressure ventilators.
Negative-Pressure Ventilators
Negative-pressure ventilators create a vacuum around the chest or body to draw air into the lungs, simulating breathing. This method does not require an...
