    Abstract: The present invention includes a system for delivering energy to an airway wall of a lung comprising an energy delivering apparatus and a PID controller having one or more variable gain factors which are rest after energy deliver has begun. The energy delivering apparatus may include a flexible elongated member and a distal expandable basket having at least one electrode for transferring energy to the airway wall and at least one temperature sensor for measuring temperature. The PID controller determines a new power set point base on an error between a preset temperature and the measured temperature. The algorithm can be Pi+1=Pi+G(αei+βei−1+γei−2) where α, β and γ are preset values and α is from 1 to 2; β is from −1 to −2; and γ is from −0.5 to 0-5. In another variation, the controller is configured to shut down if various measured parameters are exceeded such as, for example, energy, impedance, temperature, temperature differences, activation time and combinations thereof. Methods for treating a target medium using a PID algorithm are also provided.

    Abstract: A computer based system for tracking a patient's fluid volume and electrolyte (cation or anion concentration) balances, during the period extending from before surgical procedures through the recovery process, which will assist the attending physician in maintaining proper balances in the patient. The system contains automatic sensors for measuring the volumes of fluids administered to and recovered from the patient. The system also preferably contains sensors for measuring electrolyte concentrations in these fluids, and, when sensors are not available, assists the attending physician in estimating. The system assists the attending physician in creating baseline values for a patient's fluid and electrolyte values, and then accounts for the fluids going into and out of the patient to continuously track current values. Out of bounds conditions for these balances, when detected, will cause the system to issue alarms and make suggestions to the attending physician for remedial action.

    Abstract translation: 一种基于计算机的系统，用于跟踪患者的体液量和电解质（阳离子或阴离子浓度）平衡，在从外科手术到恢复过程之前的期间内，这将有助于主治医师维持患者的适当平衡。 该系统包含用于测量给予患者和从患者回收的流体体积的自动传感器。 该系统还优选地包含用于测量这些流体中的电解质浓度的传感器，并且当传感器不可用时，辅助主治医师进行估计。 该系统帮助主治医师为患者的流体和电解质值创建基线值，然后考虑流入和流出患者的流体以连续跟踪电流值。 超出这些余额的条件，当被检测到时，将导致系统发出警报，并向主治医师提出补救措施的建议。
