Distribution of Pulmonary Ventilation With the Modified Pachon Incentive vs. Another Branded Respiratory Incentive, Through Electrical Impedance Tomography, in a Healthy Volunteers of the City of Cali

Incentive spirometry is a method to stimulate deep breathing and maximum sustained inflations, which provides participants with visual feedback on the inspiratory volume achieved, favoring lung inflation. Its multiple benefits and ease of use favor adherence, making it a common device used in the clinical environment.

This device is used in pathologies or procedures that can cause decreased function and respiratory mechanics, such as thoracoabdominal surgeries, and is indicated to reduce the incidence of postoperative pulmonary complications. It is also indicated in the presence of pulmonary atelectasis or conditions that predispose to the development of pulmonary atelectasis, in patients with prolonged bed rest, patients with neuromuscular disease, patients with spinal cord injury, and patients undergoing coronary bypass, among others.

In 2004, students from the Universidad del Valle carried out an investigation whose result was the creation of the Incentivo Modificado de Pachon, a handcrafted design device that allows mobilizing flows ranging from 600 CC/sec to more than 1400 CC/sec, which characterizes it as a flow respiratory incentive.

In 2020, the device obtained the endorsement of the Superintendence of Industry and Commerce, however, to date no studies have been carried out that objectively verify the effect that the modified Pachon's incentive (Incentivo Modificado de Pachon by the name in Spanish) has on the distribution of ventilation in comparison with another Branded respiratory incentive.

Electrical Impedance Tomography is a diagnostic tool that, employing a belt of electrodes connected around the user's chest, uses the electrical characteristics of the tissue, to provide information in a non-invasive, continuous way, on foot. bedside and radiation-free on pulmonary ventilation and perfusion, as it allows repeated imaging of tidal volume distribution, as well as distinguishing the characteristic regional filling and emptying of each lung, all in real-time and safely.

In this study, the distribution of pulmonary ventilation between the modified Pachon's incentive vs. another Branded respiratory incentive will be compared, through electrical impedance tomography, in a healthy population of the city of Cali.

The hypothesis to be tested is that the distribution of Pulmonary ventilation measured by Electrical Impedance Tomography is similar between the modified Pachon's incentive and another Branded flow respiratory incentive.
