| 20080202526 | INHALATION ANAESTHESIA DELIVERY SYSTEM AND A METHOD FOR LEAK DETECTION IN THE INHALATION ANAESTHESIA DELIVERY SYSTEM - Inhalation anaesthesia delivery system and a leak detecting method, whereby the system comprises a fresh gas feeding arrangement connected to a breathing circuit, a monitor device, The monitor device is configured to monitor gas concentrations in the breathing circuit by using a sampling line. The monitor device is configured to measure at least two gas components' concentrations and identify changes, which are simultaneous towards the known ambient air concentration values of the two gas components' concentrations measured. | 08-28-2008 |
| 20080230065 | METHOD AND SYSTEM FOR MONITORING PATIENT'S BREATHING ACTION RESPONSE TO CHANGES IN A VENTILATOR APPLIED BREATHING SUPPORT - A method for monitoring patient's breathing action response to changes in a ventilator applied breathing support, where a) a desired target range for a breathing gas indication of O2-consumption for the patient is first determined, after which b) the ventilator applied breathing support is changed, and c) the breathing gas indication of O2-consumption of said patient is measured and d) compared with the desired target range. At least the steps b)-d) are repeated to maintain the measured breathing gas indication of O2-consumption of said patient within the desired target range. A system for monitoring a patient's breathing action is also provided. | 09-25-2008 |
| 20090050148 | INHALATION ANAESTHESIA DELIVERY SYSTEM AND METHOD - An inhalation anaesthesia delivery system and method, whereby the system comprises a fresh gas feeding arrangement connected to a breathing circuit, a monitor device, a control device and an interface unit. The fresh gas feeding arrangement and the ventilator are configured to deliver a desired concentration of gas to the breathing circuit, the desired concentration being set by using the interface unit. The monitor device is configured to monitor gas concentrations in the breathing circuit by analysing gases flowing in the breathing circuit, and the control device is configured to control the fresh gas feeding arrangement on the basis of the data received from the monitor device to keep the desired breathing gas concentration. The monitor device is configured to monitor expired inorganic gas concentration by comparing the measured expired breathing gas concentration with the set target value and changing the fresh gas delivery accordingly to meet the target value. | 02-26-2009 |
| 20090199854 | METHOD AND SYSTEM FOR ANESTHESIA DELIVERY - A method for delivering an anesthetic agent into a breathing air of a subject. The method for delivering an anesthetic agent into a breathing air of a subject includes feeding a target anesthetic agent concentration, measuring a concentration of the anesthetic agent component in the breathing air, comparing the measured concentration with the fed target anesthetic agent concentration, and choosing one of regulating or not regulating the delivery of the anesthetic agent into the breathing air based on the comparison to achieve the target anesthetic agent concentration. The method for delivering an anesthetic agent into a breathing air of a subject also includes delivering doses of the anesthetic agent into the breathing air, adsorbing the anesthetic agent and releasing the absorbed anesthetic agent into the breathing air. An anesthesia delivery system is also provided. | 08-13-2009 |
| 20090288661 | ARRANGEMENT AND METHOD FOR SUPERVISING MEDICAL MONITOR - An arrangement for supervising a medical monitor. The arrangement for supervising the medical monitor comprises a measurement function having at least one measurement device to make at least one measurement for obtaining measurement information for monitoring one or more patient care signals. The arrangement for supervising the medical monitor also includes a supervision analyzer configured to communicate with the measuring function and to receive the measurement information. The supervision analyzer is adapted to obtain reference information and to compare the measurement information to the reference information to determine whether the measurement function is working properly. | 11-26-2009 |
| 20100078018 | METHOD AND ARRANGEMENT FOR DETECTING A LEAK IN ANESTHESIA SYSTEM - A method and arrangement for detecting a leak in an anesthesia system. The method includes controlling respiratory movements by means of ventilator gas flows and measuring the ventilator gas flow added for an inspiration and removed for an expiration. The method also includes supplying a fresh gas flow for a respiration and measuring the fresh gas flow added for the respiration. The method further includes receiving information indicative of the measured gas flows, determining based on said received information both the gas volume added and the gas volume removed and comparing these determined gas volumes to each other. The method also includes determining based on comparing the anesthesia system leakage. | 04-01-2010 |
| 20110094509 | METHOD AND ARRANGEMENT FOR CONTROLLING NARCOTIC EFFECT VALUE OF BREATHING GAS - A method for controlling a narcotic effect value of a mixture of at least two narcotic agents of a breathing gas is disclosed herein. The method includes setting a target value for a desired narcotic effect of narcotic agents and measuring a breathing gas concentration of each narcotic agent of the breathing gas. The method also includes converting measured breathing gas concentration of each narcotic agent to a narcotic effect value of the breathing gas and calculating a total narcotic effect value of the mixture of the at least two narcotic agents. The method also includes comparing the total narcotic effect value with the target value and determining whether or not to change the breathing gas concentration to meet the target value. | 04-28-2011 |
