Background technology
In anesthetic machine and respirator control, volume control is usually with the monitoring tidal volume in the last cycle feedback control parameters as this tidal volume, the substitution system carries out feedback control, utilize formula VT=Δ V* (C-Ctube)/C, calculate patient's tidal volume, wherein Δ V tidal volume changes, and patient VT sucks tidal volume, C entire system compliance, the Ctube circuit compliance.Bring the VT that calculates into formula VT '=VT+ Δ VT*K, calculate the tidal volume deviation and feedback is controlled, wherein VT ' should reach tidal volume for the lower cycle, and Δ VT deducts the difference of patient's tidal volume for presetting tidal volume.This kind method easily produces concussion, and the tidal volume over control can occur.
Summary of the invention
The object of the present invention is to provide a kind ofly can guarantee the stable method of tidal volume control in the control of anesthetic machine and respirator, reduce in the adjustment process because of the excessive injury to human body of tidal volume.
A kind of anesthetic machine, respirator compliance compensation capacity support method is characterized in that, comprise the steps:
(1) utilize the RC fast estimation technique, start is carried out circuit compliance Ctube to anesthetic machine and respirator connecting line and is carried out self check;
(2) the circuit compliance Ctube according to self check calculates constantly pipeline capacity Vtube (t) of t, calculates and adopts following formula:
Vtube(t)＝P(t)-P(t-1)*Ctube，
The patient end pressure that constantly monitors for t of P (t) wherein, P (t-1) is patient end previous moment pressure;
(3) the t moment pipeline capacity Vtube (t) that calculates according to step (2), Real-Time Monitoring also calculates the constantly instantaneous inlet capacity Vt of patient (t) of t, calculates and adopts following formula:
Vt(t)＝Vs(t)-Vtube(t)，
Wherein Vs (t) is constantly anesthetic machine and respirator system output capacity of t;
