Abstract
A method for assisting a patient in weaning from a therapy, the method being executed by a controller, and the controller being configurable with different at least one weaning strategy. The method includes setting, based on at least one input by a user, a target weaning strategy among the at least one weaning strategy, where the at least one input corresponds to a clinical decision determined by the user.
Claims14
A method for assisting a patient in weaning from a therapy, wherein the method is executed by a controller comprising a memory, and the method comprises:
- receiving, by the controller before the therapy, multiple weaning strategies inputted into the controller;
- storing, by the controller, the multiple weaning strategies into the memory;
- receiving, by the controller during the therapy, at least one input of a user, wherein the at least one input corresponds to a clinical decision determined by the user and is used for selecting a target weaning strategy among the multiple weaning strategies stored in the memory, and the at least one input of the user comprises:
- a time interval of adjusting a flow rate and a FiO2 of a gas provided to the patient;
- and an adjusting granularity for adjusting the flow rate and the FiO2 of the gas provided to the patient;
- setting, by the controller, the target weaning strategy selected from the multiple weaning strategies, based on the time interval of adjusting the flow rate and the FiO2 of the gas provided to the patient and the adjusting granularity for adjusting the flow rate and the FiO2 of the gas provided to the patient;
- receiving, by the controller, a physiological parameter of the patient transmitted by at least one measurement device associated with the patient;
- calculating, by the controller, a percentage that a value of the received physiological parameter deviates from a reference value comprised in the set target weaning strategy;
- determining, by the controller, that a condition of the patient is stable in a case that the percentage is not greater than a second preset value;
- determining, by the controller, that the condition of the patient is not stable in a case that the percentage is greater than the second preset value;
- adjusting, by the controller according to whether the condition of the patient is stable, the flow rate and the FiO2 of the gas provided to the patient, based on the time interval of adjusting the flow rate and the FiO2 of the gas provided to the patient and the adjusting granularity for adjusting the flow rate and the FiO2 of the gas provided to the patient;
- and
- outputting a weaning signal in a case that the flow rate of the gas provided to the patient is less than 10 litre per minute or the FiO2 of the gas provided to the patient is less than 50%, wherein the weaning signal is used to inform the user that the patient can be weaned from the therapy;
- wherein the physiological parameter comprises a respiratory rate, and, in a case that the condition of the patient is not stable, the method further comprises:
- determining whether the respiratory rate is greater than a third preset value, wherein the third preset value is used to determine whether the patient is in a critical state;
- and
- outputting an alarm signal in a case that the respiratory rate is greater than the third preset value.
14 more elements
A controller, comprising:
- at least one processor;
- and
- a memory communicatively connected with the at least one processor;
- wherein the memory stores instructions executable by the at least one processor, and the instructions, when executed by the at least one processor, cause the at least one processor to:
- receive, before the therapy, multiple weaning strategies inputted into the controller;
- store the multiple weaning strategies into the memory;
- receive, during the therapy, at least one input of a user, wherein the at least one input corresponds to a clinical decision determined by the user and is used for selecting a target weaning strategy among the multiple weaning strategies stored in the memory, and the at least one input of the user comprises:
- a time interval of adjusting a flow rate and a FiO2 of a gas provided to the patient;
- and an adjusting granularity for adjusting the flow rate and the FiO2 of the gas provided to the patient;
- set the target weaning strategy selected from the multiple weaning strategies, based on the time interval of adjusting the flow rate and the FiO2 of the gas provided to the patient and the adjusting granularity for adjusting the flow rate and the FiO2 of the gas provided to the patient;
- receive a physiological parameter of a patient transmitted by at least one measurement device associated with the patient;
- calculate a percentage that a value of the received physiological parameter deviates from a reference value comprised in the set target weaning strategy;
- determine that a condition of the patient is stable in a case that the percentage is not greater than a second preset value;
- determine that the condition of the patient is not stable in a case that the percentage is greater than the second preset value;
- adjust, according to whether the condition of the patient is stable, the flow rate and the FiO2 of the gas provided to the patient, based on the time interval of adjusting the flow rate and the FiO2 of the gas provided to the patient and the adjusting granularity for adjusting the flow rate and the FiO2 of the gas provided to the patient;
- and
- output a weaning signal in a case that the flow rate of the gas provided to the patient is less than 10 litre per minute or the FiO2 of the gas provided to the patient is less than 50%, wherein the weaning signal is used to inform the user that the patient can be weaned from the therapy;
- wherein the physiological parameter comprises a respiratory rate, and, in a case that the condition of the patient is not stable, the at least one processor is further caused to:
- determine whether the respiratory rate is greater than a third preset value, wherein the third preset value is used to determine whether the patient is in a critical state;
- and
- output an alarm signal in a case that the respiratory rate is greater than the third preset value.
