Abstract
The invention discloses a respirator triggering time parameter monitoring method. For a respirator having a pressure trigger mechanism, the method comprises following steps: monitoring the airway pressure P1; starting to time when the difference between the airway pressure P1 and the end-expiratory pressure P2 is less than a pressure trigger sensitivity and recording the moment as a trigger initial moment T1; stopping timing when the airway pressure P1 is equal to the end-expiratory pressure P2 and recording the moment as a trigger ending moment T2; and calculating the triggering time according to a formula that Ttrigger = T2 - T1. For a respirator having a flow triggering mechanism, the method comprises following steps: simultaneously monitoring the inspiration flow speed F1 and the expiration flow speed F2; starting to time when the difference between the inspiration flow speed F1 and the expiration flow speed F2 is larger than a flow speed trigger sensitivity and recording the moment as the trigger initial moment T1; stopping timing when the inspiration flow speed F1 is equal to the expiration flow speed F2 and recording the moment as the trigger ending moment T2; and calculating the triggering time according to the formula that Ttrigger = T2 - T1. The method is simple and reliable.

Technical field
The invention belongs to respirator technical field, be specifically related to a kind of respirator triggered time parameter monitoring method.
Background technology
At present, respirator inspiration trigger mechanism has pressure activated mechanism and flow triggering mechanism two kinds.Because respirator and artificial airway can produce additional drag, for reducing the extra work of patient, trigger sensitivity should be arranged in comparatively responsive level.According to preliminary clinical research, compared with pressure activated, adopt flow triggering can reduce the work of breathing of patient further, make patient more comfortable.But also breathe no more the machine monitoring to respirator triggered time parameter itself at present, the triggered time not only can help doctor to arrange suitable trigger sensitivity, can also evaluate the response speed that a respirator triggers patient.
In clinical, also neither one parameter can have directive significance to the setting of trigger sensitivity, rely on the experience of clinician completely, and triggered time parameter can help doctor to judge, and whether trigger sensitivity is reasonable, respirator triggers response speed to patient can also be evaluated, provide certain help to clinical research.Therefore, a kind of respirator triggered time parameter monitoring method is urgently proposed.

The present invention one of is intended to solve the problems of the technologies described above at least to a certain extent or at least provides a kind of useful business to select.For this reason, the object of the invention is to propose a kind of simple respirator triggered time parameter monitoring method.
The respirator triggered time parameter monitoring method of embodiment according to a first aspect of the present invention, described respirator inspiration trigger mechanism is pressure activated mechanism, comprise the following steps: monitoring airway pressure P1, start timing when the difference of described airway pressure P1 and end-tidal pressure P 2 is less than pressure activated sensitivity, record is now for triggering initial time T1; Terminate timing when described airway pressure P2 is equal with described end-tidal pressure P 2, record is now for triggering end time T2; Calculating pressure triggers duration Ttrigger=T2-T1.
Alternatively, described pressure activated sensitivity is-0.5 ~-20cm H
2o.
The respirator triggered time parameter monitoring method of embodiment according to a second aspect of the present invention, described respirator inspiration trigger mechanism is flow triggering mechanism, comprise the following steps: monitor inspiratory flow rate F1 and exhalation flow rate F2 simultaneously, start timing when the difference of described inspiratory flow rate F1 and described exhalation flow rate F2 is greater than flow velocity trigger sensitivity, record is now for triggering initial time T1; Terminate timing when described inspiratory flow rate F1 is equal with described exhalation flow rate F2, record is now for triggering end time T2; Calculating pressure triggers duration Ttrigger=T2-T1.
