Description
Technical field
The invention belongs to lung ventilator technical field, tidal volume is adjusted under IPPV ventilating modes the present invention relates to a kind of
Method.
Background technology
Under IPPV patterns, the method for existing regulation tidal volume does not often account for the compliance of pipeline and lung
Problem, because the compliance of lung is nonlinear system, therefore the method for traditional regulation tidal volume is not special
Precisely.
The content of the invention
It is an object of the present invention to provide a kind of method that tidal volume is adjusted under IPPV ventilating modes, the method fills
Divide the influence adjusted to tidal volume in view of compliance of the respiratory system and circuit compliance, calculated always by compliance
The tidal volume of body consumption, in the respiratory cycle, is gone using the deviation of the tidal volume for setting with the deviation of actual tidal volume
The tidal volume of total consumption is adjusted, the method is simple and easy to apply, there is preferable tidal volume to adjust effect in IPPV patterns
Really.
To reach above-mentioned purpose, present invention employs following technical scheme：
A kind of method that tidal volume is adjusted under IPPV ventilating modes, the described method comprises the following steps：
1) setting tidal volume, inspiratory/expiratory and respiratory rate, the inspiratory flow rate of inlet valve is calculated according to following formula；
Inspiratory flow rate=setting tidal volume/inspiratory duration, inspiratory duration=60/ respiratory rate × (inspiratory duration/(during air-breathing
Between+expiratory duration))；
2) cut-in voltage of inlet valve is obtained according to the corresponding table of air-breathing threshold voltage and flow velocity by inspiratory flow rate, one is exhaled
After the gas cycle, overall tidal volume is calculated according to following formula；
Overall tidal volume=system compliance/(system compliance-circuit compliance) × setting tidal volume；
3) actual tidal volume is calculated according to following formula；
The tidal volume of actual tidal volume=entirety tidal volume-pipeline consumption；
4) according to setting tidal volume and the difference of actual tidal volume, by adjusting inspiratory flow rate, so as to adjust inlet valve
Cut-in voltage, and then adjust overall tidal volume.
Step 4 of the present invention) in overall tidal volume regulation, when actual tidal volume has deviation with setting tidal volume,
The flow for controlling inlet valve to provide by adjusting the voltage of inlet valve so that the close setting moisture of actual tidal volume
Amount.
The present invention by adjusting overall tidal volume, and then adjusts actual in the case where pipeline consumption tidal volume is constant
Tidal volume, makes actual tidal volume close to setting tidal volume.
Tidal volume as the lung tidal volume to be reached is set in the present invention, actual tidal volume is the tidal volume that actual lung reaches,
The tidal volume of overall tidal volume=actual tidal volume+pipeline consumption.
Inspiratory/expiratory=inspiratory duration/expiratory duration in the present invention.
The tidal volume of system compliance, circuit compliance and pipeline consumption is constant in the present invention, can be according to institute
The pipeline for using is obtained.
It is not specified in the present invention to use routine techniques.
The present invention can reach in this approach application to IPPV patterns by the tidal volume regulation of test machine and compare
Preferable effect.
The present invention considers the compliance of pipeline and the compliance of lung, according to each actual tidal volume and setting tidal volume
Difference, the tidal volume that de-regulation is totally consumed, this method considers the compliance of lung and the compliance in loop, letter
It is single easy.
Brief description of the drawings
Fig. 1 is the flow chart of the inventive method.
Specific embodiment
With the drawings and specific embodiments, the present invention is further detailed explanation below.
As shown in figure 1, it is a kind of under IPPV ventilating modes adjust tidal volume method, methods described include following step
Suddenly：
1) setting tidal volume, inspiratory/expiratory and respiratory rate, the inspiratory flow rate of inlet valve is calculated according to following formula；
Inspiratory flow rate=setting tidal volume/inspiratory duration, inspiratory duration=60/ respiratory rate × (inspiratory duration/(during air-breathing
Between+expiratory duration))；
2) cut-in voltage of inlet valve is obtained according to the corresponding table of air-breathing threshold voltage and flow velocity by inspiratory flow rate, one is exhaled
After the gas cycle, overall tidal volume is calculated according to following formula；
Overall tidal volume=system compliance/(system compliance-circuit compliance) × setting tidal volume；
3) actual tidal volume is calculated according to following formula；
The tidal volume of actual tidal volume=entirety tidal volume-pipeline consumption；
4) according to setting tidal volume and the difference of actual tidal volume, by adjusting inspiratory flow rate, so as to adjust inlet valve
Cut-in voltage, and then adjust overall tidal volume.
It is 600mL when interface sets tidal volume using the above method, inspiratory/expiratory is 1:2, respiratory rate is 10,
Inspiratory duration=60/10 × (1/3)=2 second, inspiratory flow rate=tidal volume/inspiratory duration=600/2=300ml/S=18L/min.
Inspiratory flow rate is being obtained, related tidal volume is being calculated according to the actual respiratory system for being used and is adjusted.
It should be noted last that, the above embodiments are merely illustrative of the technical solutions of the present invention and it is unrestricted.Although
The present invention is described in detail with reference to embodiment, it will be apparent to an ordinarily skilled person in the art that to the present invention
Technical scheme modify or equivalent, without departure from the spirit and scope of technical solution of the present invention, its is equal
Should cover in the middle of scope of the presently claimed invention.
