A method for controlling breathing gas flow of a ventilator for assisted or controlled ventilation of a patient as a function of a tracheobronchial airway pressure of the patient. A ventilator tube, such as a tracheal tube or tracheostomy tube, can be introduced into a trachea of the patient and subjected to the breathing gas, and has an inflatable cuff and at least one lumen that is continuous from a distal end of the tube to a proximal end of the tube. An apparatus detects an airway pressure, in which the tracheobronchial airway pressure is ascertained by continuous or intermittent detection and evaluation of an intra-cuff pressure prevailing in the cuff of the tube inserted into the trachea. The breathing gas flow of the ventilator is controlled as a function of the intra-cuff pressure detected.

The invention relates to a pneumatic gas-controlled breathing machine which takes gas as a power source. High-pressure gas forms periodic operation through a pneumatic valve so as to supply a proper tidal volume and breathing frequency for a patient. The pneumatic gas-controlled breathing machine only needs to be connected with the gas source so as to supply the proper tidal volume and breathing frequency for the patient through a reducing valve and a control valve of the pneumatic gas-controlled breathing machine self, and the control valve of the pneumatic gas-controlled breathing machine can adjust the breathing frequency and the tidal volume. A normally open valve is closed when the normally open valve controls the pressure of a gas cavity body to rise to a set value, control gas in the gas cavity body is controlled by a normally closed valve and is discharged from an air-resistor simultaneously when the normally open valve is closed, and the normally closed valve recovers to be in the closed state, so that gas supply at the rear end of the normally closed valve is stopped, the time slot from the moment to the next time of ventilation of the normally closed valve is the time for the patient to breathe, and then the process from inhaling to exhaling of the patient is finished. The pneumatic gas-controlled breathing machine works repeatedly in the way.

The invention discloses an anesthesia depth monitoring method. The anesthesia depth monitoring method monitors anesthesia depth by detecting isoprene content in a patient's breath. By detecting the isoprene content in the patient's breath, a real-time noninvasive anesthesia depth monitoring method is established; and the established anesthesia depth monitoring method is far superior to electroencephalography monitoring from a practical point of view. When electroencephalography monitoring is being performed, brain electrodes must be attached to surface areas of corresponding brain regions of the patient; and thus, anesthesia depth cannot be monitored at the corresponding points of the brain in craniocerebral surgery and facial surgery. On the contrary, the method for monitoring the anesthesia depth by detecting the isoprene content in the patients' breath is suitable for any patients for gas sample can be extracted from the patients' breath, no matter the patients are in spontaneous breathing or machine-controlled breathing during operation, so as to be subjected to gas chromatographic analysis; and thus, the method is not limited by conditions, such as surgery type, patient age and the like.
