Circuit Tubing and Neurally Adjusted Ventilatory Assist (NAVA): Enhanced Synchrony


In recent years, medical technology has made tremendous strides, leading to innovative solutions that enhance patient care and comfort. One such advancement in respiratory therapy is the integration of Circuit Tubing and Neurally Adjusted Ventilatory Assist (NAVA), which focuses on improving synchrony between a patient and a ventilator. In this article, we will explore the benefits of this technology and how it enhances patient outcomes.

Enhanced Synchrony:

Synchrony refers to the coordination between a patient’s breathing effort and the delivery of ventilatory support. Without proper synchrony, patients can experience discomfort, inefficient ventilation, and poor outcomes. Circuit Tubing and NAVA are designed to address these challenges by providing enhanced synchrony, resulting in better patient comfort and improved efficiency of ventilator support.

How it Works:

Circuit Tubing is a system that connects the patient to the ventilator through a specially designed breathing circuit. This tubing system is equipped with sensors that detect the patient’s neural breathing signals, which are then used to adjust the ventilator settings in real-time. These sensors pick up the electrical activity of the diaphragm, allowing for precise and immediate adjustments to the amount and timing of ventilatory support provided.

NAVA is the software component that processes the neural breathing signals picked up by the Circuit Tubing sensors. It converts these signals into ventilator support, ensuring that the patient receives the right level of assistance with each breath. This technology effectively synchronizes the patient’s breathing efforts and the ventilator-delivered support, resulting in improved comfort and better patient outcomes.


1. Improved Patient Comfort: Circuit Tubing and NAVA provide enhanced synchrony, leading to greater patient comfort during ventilation therapy. By precisely adjusting the ventilator support to match the patient’s needs, the therapy feels more natural and less invasive. This increased comfort level can lead to reduced anxiety and improved overall patient experience.

2. Enhanced Efficiency: Proper synchrony between a patient and the ventilator allows for more efficient ventilation. Circuit Tubing and NAVA technology facilitate accurate adjustments to ventilation parameters, enabling optimal oxygenation and carbon dioxide removal. With improved efficiency, patients may experience faster recovery times and reduced dependence on ventilatory support.

3. Reduced Complications: Circuit Tubing and NAVA can help reduce complications associated with traditional ventilation methods, such as ventilator-induced lung injury or patient-ventilator asynchrony. By precisely matching the patient’s breathing efforts with ventilatory support, the risk of volutrauma, barotrauma, and patient discomfort is minimized.


Circuit Tubing and Neurally Adjusted Ventilatory Assist (NAVA) have revolutionized the field of respiratory therapy by enhancing synchrony between patients and ventilators. This innovative technology not only improves patient comfort during ventilation but also enhances efficiency and reduces complications associated with traditional methods. By integrating Circuit Tubing and NAVA into respiratory care protocols, healthcare professionals can provide their patients with superior care and achieve better outcomes. As medical technology continues to advance, we can expect further improvements that prioritize patient well-being and comfort.
