Item Métodos de calibración para insufladores abdominales(Universidad Santiago de Cali, 2020) Hernández Mendoza, Jefferson; López Pacheco, Moisés; Bermeo Varón, Leonardo AntonioThe pneumoinflator or abdominal insufflator is a fundamental equipment in a large number of surgical specialties, mainly in laparoscopic surgeries. It is used for the introduction of CO2 into the abdominal cavity, known as pneumoperitoneum, to generate adequate working conditions for intervention. the gas supplied in terms of volume, flow and pressure, are essential to prevent adverse events such as hypercapnia, hypothermia and embolism. Given the importance of a pneumo-insufflator when used in surgery, the health care institutions should verify that their equipment is in optimal conditions of use, with periodic calibration and good management of preventive maintenance-oriented at risks. For pneumoinflator equipment, there is a wide and diverse variety of calibration methods because the equipment has two separately creditable variables such as flow and pressure, but there is no standardization of a guaranteed method or of the coupled variables for this equipment, which could lead to possible errors at the time of calibration. Thus, in this paper presents the most relevant calibration methods for abdominal insufflators. A standardized method is suggested to help reduce errors that may arise in the calibration process, the unification of calculations and a better estimate of uncertainty. Additionally, the principle of operation of the equipment, its characteristics, maintenance routine, internal composition and the complications that could occur during surgery are presented.
