    Introduction: The abdominal cavity and the thoracic cage are separated by the diaphragm; therefore, the variations in the pressures within one of them have an effect on the pressures of the other. At present, intra-abdominal hypertension is a frequent entity in the critically ill patient, which constitutes an important risk factor for complications and mortality since it influences on different organs and systems.Objective: To relate intra-abdominal pressure with mechanical artificial ventilation pressures and parameters of respiratory, cardiovascular and renal function.Material and Methods: A descriptive prospective study of intra-abdominal pressure was conducted in patients undergoing mechanical ventilation with clinical and surgical diseases in the Intensive Care Units of the Arnaldo Milán Castro Hospital, during the period between January 2014 until December 2015. Results:  Clinical patients with high values of airway pressures showed higher values of intra-abdominal pressure, and those post-surgical patients who presented with high levels of pressure inside the abdomen indicated the highest values of peak and average pressure recorded in the mechanical ventilator.  Conclusions: Mean arterial pressure, diuretic rate and peripheral oxygen saturation decreased, whereas the central venous pressure, the partial pressure of carbon dioxide in blood, and creatinine increased due to raises in pressure within the abdomen.Keywords: Artificial respiration, transcutaneous blood gas monitoring, arterial pressure, diuresis,             abdomen.</p

La hipertensión intraabdominal es hoy una entidad frecuente en el paciente crítico en el que constituye un factor de riesgo importante de complicaciones y mortalidad, ya que influye sobre órganos y sistemas.Objetivo: Relacionar la presión intraabdominal con presiones de la ventilación artificial mecánica y parámetros de la función respiratoria, cardiovascular y renal. Material y Métodos: Se realizó un estudio descriptivo y prospectivo de la presión intraabdominal en pacientes sometidos a ventilación mecánica, con enfermedades clínicas y quirúrgicas, en las Unidades de Cuidados Intensivos del Hospital Clínico Quirúrgico “Arnaldo Milán Castro”, durante el período comprendido entre enero 2014 hasta diciembre 2015.Resultados: Los pacientes clínicos con presiones de la vía aérea elevadas mostraron valores más altos de presión intraabdominal, y aquellos pacientes postquirúrgicos que cursaron con niveles altos de presión dentro del abdomen también presentaron los valores más elevados de presión pico y media registradas en el ventilador mecánico.Conclusiones: La tensión arterial media, el ritmo diurético y la saturación periférica de oxígeno disminuyeron, mientras que la presión venosa central, la presión parcial de dióxido de carbono en sangre y la creatinina aumentó ante los aumentos de la presión dentro del abdomen.Palabras claves: Respiración artificial, monitoreo de gas sanguíneo transcutáneo, presión arterial, diuresis, abdomen
