A computer-controlled servo lung simulator including a mechanical piston which simulates the mechanical properties of the human lung, chest wall and diaphragm. The computer control implemented in the invention includes methods for controlling the servo lung simulator to provide the simulation and control signals for the mechanical piston. The invented servo lung simulator includes abilities such as (a) providing a one or two compartment lung simulation of pediatric and adult patients, (b) simulation of an active chest wall that can emulate triggering events as well as spontaneous breathing, (c) measurement of volume and flow to better than 1% accuracy, (d) compliance and resistance elements can be chosen from an almost infinite spectrum of possibilities, (e) enables user to collect, display and store various data results like flow, volume, pressures, peak pressure, pause pressure, breath rate, (f) able to measure work of breathing, trigger response times and other indicators of the quality of spontaneous breathing support modes, (g) simulation of coughs, sighs, ventilatory dysynchrony, and other spontaneous diaphragm and chest wall components of respiration.

A method and system for managing mechanical ventilation of patients with respiratory disorders is described. The main objective of the system is to generate executable instructions for patient care which take into account a large number of parameters of patient condition and ventilation. Data regarding the state of the patient are stored in a database. Patient data are processed according to a set of protocols which contain rules for patient care decisions arranged in a logical sequence to generate detailed, executable instructions for patient care. Instructions are updated when new data are entered into the database. The data can be acquired in an automated fashion, or the clinician can be instructed to collect and enter new data into the clinical database. Likewise, patient care instructions can be carried out automatically or manually, but it is preferred that instructions are carried out manually as a safety check. The preferred embodiment of the invention includes a computer system, software for processing patient data, and a display device for presenting patient care instructions to the clinician.
