The method for automatically adjusting mechanical ventilation parameters.
Fig. 1 is the flow chart of the method for the mechanical ventilation parameters of automatic adjustment of the embodiment of the present invention.
As shown in Figure 1, the method for the automatic adjustment machinery ventilation parameters the following steps are included:
In step s101, current EtCO is detected2Concentration.
It should be noted that during being anaesthetized using machine, the embodiment of the present invention can be according to exhaling last dioxy
Change concentration of carbon (i.e. EtCO2) measurement result to ventilation implement automation intervene, to keep EtCO2Close to normal level.Its
In, EtCO2It is too low or excessively high, it is not adjusted yet after automation is intervened to normal level, the ventilation for leading to its consequence may be prompted

Especially, for carrying out mechanical ventilation person, by monitoring EtCO2Waveform also can determine whether the position of tracheal catheter
It sets, and the failures such as gas leakage issuable in venting process, catheter twist, airway obstruction is found and alarmed in time.
It is understood that in starting EtCO2After self-regulating process, it is divided into appearance control regulative mode and voltage-controlled adjusting side
Formula, VCV, SIMV_VC, PCV_VG, SIMV_VG are to control the mode of target using control regulative mode is held with tidal volume, pass through control
The ventilatory frequency of machine processed and tidal volume adjust EtCO2Concentration；PCV, SIMV_PC are the ventilating mode for controlling target with pressure
Using voltage-controlled regulative mode, EtCO is adjusted by controlling ventilatory frequency and the goal pressure of machine2Concentration.Below to the present invention
The working principle that the automatic adjustment of embodiment is intervened is described in detail.
In step s 102, if current EtCO2Concentration is not in preset concentration section, and machine is logical in volume controlled
Gas mode, then the ventilatory frequency for controlling machine and tidal volume are so that current EtCO2Concentration reaches aimed concn.
Wherein, in one embodiment of the invention, the ventilatory frequency and tidal volume for controlling machine are so that current EtCO2It is dense
Degree reaches aimed concn, further comprises: in current EtCO2It is default with first when concentration is greater than the upper limit in preset concentration section
The ventilatory frequency of step value hoisting machine, and when the ventilatory frequency of machine reaches the ventilatory frequency maximum value of machine, with second
Default step value increases tidal volume；In current EtCO2When concentration is less than the lower limit in preset concentration section, step value is preset with third
The ventilatory frequency of machine is reduced, and when the ventilatory frequency of machine reaches the ventilatory frequency minimum value of machine, with the 4th default step
Reduce tidal volume into value.
For example, as shown in Fig. 2, for the appearances control mode such as VCV, i.e. volume controlled ventilation mode works as EtCO2Concentration, which is greater than, to be set
When target upper limit (preset concentration section can be understood as concentration normal range (NR)) set, the ventilatory frequency of machine is first incrementally increased,
To enhance the autonomous respiration frequency of patient, the ventilatory frequency+2 of machine is adjusted every time, when the ventilatory frequency of machine reaches setting
Maximum value Freqmax when, then adjust tidal volume, each tidal volume+2ml/kg；In the ventilatory frequency and tidal volume for increasing machine
During, if when plateau pressure Pplat >=35cmH20 or surge pressure Ppeak >=PMax, stopping increasing adjusting,
It returns to last parameter to ventilate, maximum plateau pressure is limited within 35cmH20, peak-peak pressure limit exists
PMax or less.
In another example as shown in Fig. 2, working as EtCO for the appearances control mode such as VCV2Concentration is less than the EtCO of setting2Target lower limit
When, adjustment process is the ventilatory frequency for first gradually reducing machine, the ventilatory frequency -2 of machine is adjusted every time, when the ventilation frequency of machine
When rate reaches the ventilatory frequency lower limit Freqmin of machine, then reduce tidal volume, each tidal volume -2ml/kg；When tidal volume reduces
When to 6ml/kg, stop reducing and adjust, returns to last parameter and ventilate, guarantee tidal volume minimum in 6ml/kg or more.
In step s 103, if current EtCO2Concentration is not in preset concentration section, and machine is in pressure control and leads to
Gas mode, then the ventilatory frequency for controlling machine and goal pressure are so that current EtCO2Concentration reaches aimed concn.
Wherein, in one embodiment of the invention, the ventilatory frequency and goal pressure for controlling machine are so that current EtCO2
Concentration reaches aimed concn, further comprises: in current EtCO2It is pre- with the 5th when concentration is greater than the upper limit in preset concentration section
If the ventilatory frequency of step value hoisting machine, and when the ventilatory frequency of machine reaches the ventilatory frequency maximum value of machine, with
Six default step values increase goal pressure；In current EtCO2When concentration is less than the lower limit in preset concentration section, with the 7th default step
The ventilatory frequency of machine is reduced into value, and when the ventilatory frequency of machine reaches the ventilatory frequency minimum value of machine, it is pre- with the 8th
If step value reduces goal pressure.
For example, as shown in figure 3, mode voltage-controlled for PCV etc., i.e. pressure controlled ventilation mode, work as EtCO2Concentration, which is greater than, to be set
When the target upper limit set, the ventilatory frequency of machine is first incrementally increased, the ventilatory frequency+2 of machine is adjusted every time, when the ventilation of machine
When frequency reaches the maximum value Freqmax of setting, then goal pressure is adjusted, each goal pressure Ptarget+2cmH20；Increasing
During the ventilatory frequency and goal pressure of big machine, if plateau pressure Pplat >=35cmH20 or surge pressure
When Ppeak >=PMax, then stop increasing adjusting, returns to last parameter and ventilate, maximum plateau pressure is limited in
Within 35cmH20, peak-peak pressure limit is in PMax hereinafter, Ptarget is set as the smaller value of Pmax and 35cmH20.
In another example as shown in figure 3, mode voltage-controlled for PCV etc., works as EtCO2Concentration is less than the EtCO of setting2Target lower limit
When, adjustment process is the ventilatory frequency for first gradually reducing machine, the ventilatory frequency -2 of machine is adjusted every time, when the ventilation frequency of machine
When rate reaches the ventilatory frequency lower limit Freqmin of machine, then reduce goal pressure, each goal pressure -2cmH20；When monitoring tide
When tolerance Vte is reduced to 6ml/kg, stop reducing adjusting, return to last parameter and ventilate, guarantees that tidal volume minimum exists
6ml/kg or more
In addition, in one embodiment of the invention, further includes: if pressure reaches upper pressure limit value, and current EtCO2
Concentration is greater than high alarm setting threshold value, then issues the first alerting signal；If the ventilatory frequency and tidal volume of machine reach corresponding
Lower limit value, and current EtCO2Concentration is lower than low alarm setting threshold value, then issues the second alerting signal.
For example, for the appearances control mode such as VCV, when stopping increasing adjusting, if EtCO at this time2Concentration is still greater than
The target upper limit of setting, then prompt pressure to have reached the upper limit, if monitoring EtCO2Concentration is greater than high alarm setting, then prompt is asked
Doctor pays attention to CO2It divides excessively high；When stopping reducing adjusting, if EtCO at this time2EtCO of the concentration still less than setting2Target
Lower limit then prompts the ventilatory frequency of tidal volume and machine to have reached lower limit, if monitoring EtCO2Concentration is lower than low alarm setting,
It then prompts " doctor to be asked to judge whether the imbalance of venting QI-blood flow ratio occur！".
Mode voltage-controlled for PCV etc., when stopping increasing adjusting, if EtCO at this time2The mesh of setting is still greater than in concentration
Limit is put on, then prompts pressure to have reached the upper limit, if monitoring EtCO2When concentration is greater than high alarm setting, then prompt asks doctor to infuse
Anticipate CO2It divides excessively high；When stopping reducing adjusting, if EtCO at this time2EtCO of the concentration still less than setting2Target lower limit, then
The ventilatory frequency of prompt tidal volume and machine has reached lower limit, if monitoring EtCO2Concentration is lower than low alarm setting, then prompts
" doctor is asked to judge whether the imbalance of venting QI-blood flow ratio occur！".
