Insights

Children with repaired tracheo-oesophageal fistula (TOF) exhibit reduced lung function. The forced oscillation technique (FOT) effectively assesses lung function in these children, correlating with spirometry.

Area of Science:

  • Pediatric Pulmonology
  • Respiratory Physiology

Background:

  • Tracheo-oesophageal fistula (TOF) and oesophageal atresia (OA) are congenital anomalies frequently leading to pulmonary complications in early childhood.
  • Assessing lung function in young children with repaired TOF/OA is crucial for monitoring their respiratory health.

Purpose of the Study:

  • To investigate the utility of the forced oscillation technique (FOT) for evaluating lung function in young children diagnosed with repaired TOF/OA.
  • To compare FOT-derived lung function parameters with spirometry in this patient group.

Main Methods:

  • Forty children with repaired TOF/OA and 20 healthy controls underwent lung function testing.
  • Forced oscillation technique (FOT) measurements (Rrs6, Xrs6, Rrs8, Xrs8) and spirometry (FEV(1), FVC) were performed.
  • Results were compared to reference values using z-scores.

Main Results:

  • Acceptable FOT measurements were obtained in most participants.
  • Children with TOF showed significantly higher resistance (Rrs6) and lower reactance (Xrs6) compared to controls.
  • Spirometry revealed significantly lower FEV(1) z-scores in children with TOF.

Conclusions:

  • Repaired TOF is associated with diminished lung function in children.
  • FOT is a sensitive method for assessing lung function in young children with TOF/OA, even when spirometry is challenging.
  • FOT serves as an objective tool for monitoring the clinical progress of children with TOF.

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...
Tracheostomy: Procedure and Tubes01:28

Tracheostomy: Procedure and Tubes

A tracheostomy is a surgical procedure that creates an artificial opening into the trachea, typically at the second or third cartilaginous ring level. This opening allows the insertion of a tracheostomy tube, which can replace an endotracheal tube, provide mechanical ventilation, bypass an upper airway obstruction, or remove accumulated tracheobronchial secretions.
Tracheostomy tubes can be made of semiflexible plastic (polyurethane or silicone), rigid plastic, or metal, and they come in...
Tracheostomy Suctioning II: Procedure01:23

Tracheostomy Suctioning II: Procedure

Tracheostomy suctioning is a vital nursing procedure that involves removing secretions from the tracheostomy tube to maintain airway patency and prevent respiratory complications. Nurses need to understand the proper technique for tracheostomy suctioning to ensure patient safety and comfort. In this guide, we will outline the step-by-step process for performing tracheostomy suctioning, including preparing the sterile field, donning personal protective equipment (PPE), lubricating and connecting...
Tracheostomy Decannulation01:21

Tracheostomy Decannulation

Tracheostomy decannulation is a significant milestone in the liberation of mechanically ventilated patients. Despite its importance, there is no universally accepted protocol for this procedure. This demands an evidence-based, individualized approach.
Description of the Procedure
Decannulation refers to the permanent removal of the tracheostomy tube, signaling the resolution of the condition that initially necessitated the tracheostomy. The process requires a well-coordinated interplay between...
Respiratory Volumes01:15

Respiratory Volumes

Respiratory volumes are crucial metrics, meticulously measured to quantify the air exchanged in and out of the lungs during various phases of the breathing cycle. These precise measurements are vital for assessing lung function, diagnosing respiratory conditions, and monitoring overall respiratory health. Each parameter provides specific insights into the mechanics of breathing and the functional capacity of the lungs.
Tidal Volume (TV) Tidal volume (TV) is the air inhaled or exhaled in a...
