Overview
Brief Summary
The research consist of measuring respiratory variability of several variables of the respiratory pattern at rest and during exercise using a thoracic movement measuring technique. The objective is to confirm the ability of this technique to measure the respiratory variability in healthy subjects comparing to flow measurements by a pneumotachograph. In a second step, the thoracic movement technique is applied to measure respiratory variability before and after surgery in patients after abdominal surgery with laparotomy. The objective is to observe a decrease of variability in subjects developing or at risk to develop a postoperative pulmonary complication.
Detailed Description
The incidence of Postoperative Pulmonary Complications after non-thoracic surgery varie between 2 and 19%. Postoperative Pulmonary Complications are associated with an increase of morbi-mortality and longer hospital stays. However, few possibilities are available to identify Postoperative Pulmonary Complications except predictions scores and SpO2, which decreases only face to a significant lung disease. Besides, the respiratory variability decreases during pulmonary stress situations, and is associated with an increase of mortality during mechanical ventilation. The hypothesis is that a decrease of the respiratory variability between the preoperative and the postoperative measures is associated with an increase of Postoperative Pulmonary Complications . However there is no mesuring tool of easy access in clinical practice. That is why, in a first step, a thoracic sensor belt will be tested on healthy subjects. This sensor belt is available to measure the respiratory variability.
