摘要：
A patient care system (90) comprising a pump (150A) for administering a medicinal liquid to a patient； a controller (100) in communication with the pump to control the operation of the pump； a dose request switch (135) of PCA connected to the controller with which the patient can request the pump to infuse a quantity of analgesic； a control unit (150B) that controls the patient's expiration air for CO2 and provides a measured value of CO2 to the controller； and a memory (250) with which the controller is connected, the memory comprising a range of acceptable stored CO2 values； wherein the controller compares the measured value of the CO2 it receives from the control unit with the range of acceptable values stored in the memory and if the measurable value is outside the range stored in the memory, the controller performs a predetermined action； the system being characterized in that, before allowing the pump to infuse the amount of analgesic requested, the controller compares a rate of change of the CO2 it receives from the control unit with the range of acceptable values to determine a rate of change of the stored CO2 in the memory and does not allow the pump to infuse the patient with the amount of analgesic requested if the exchange rate does not match the acceptable values with respect to the CO2 exchange rate.Un sistema de atención al paciente (90) que comprende una bomba (150A) para administrar un líquido medicinal a un paciente； un controlador (100) en comunicación con la bomba para controlar el funcionamiento de la bomba； un interruptor (135) de solicitud de dosis de PCA conectado al controlador con el que el paciente puede solicitar a la bomba infundir una cantidad de analgésico； una unidad de control (150B) que controla el aire de expiración del paciente para el CO2 y proporciona un valor medido de CO2 al controlador； y una memoria (250) con la que se conecta el controlador, comprendiendo la memoria un intervalo de valores aceptables almacenados del CO2； en
