S101：获取用户输入的启动指令，获取缓冲间目标静压值和救治间目标静压值，获取缓冲间的缓冲间第一当前静压值和救治间的救治间第一当前静压值。
在一个具体的实施场景中，用户输入启动指令，例如，按下启动按钮或者在预设的移动终端输入启动指令。用户可以提前预设缓冲间目标静压值和救治间目标静压值，也可以在启动指令中包括缓冲间目标静压值和救治间目标静压值，还可以在输入启动指令后输入缓冲间目标静压值和救治间目标静压值。缓冲间目标静压值略大于救治间目标静压值，例如缓冲间目标静压值为-5pa，救治间目标静压值-10pa。通过微压传感器等设备获取缓冲间的缓冲间第一当前静压值和救治间的救治间第一当前静压值。

S105：获取缓冲间的缓冲间第二当前静压值，根据缓冲间第二当前静压值调整缓冲排风风机的转速，使得缓冲间第二当前静压值调整为缓冲间目标静压值。

在本实施场景中，由于主排风风机以第二转速运转第一时长，负压隔离病房内的救治间内的气压将持续下降，进风风机运转后，负压隔离病房的救治间内的气压会有所升高，由于进风风机的转速是固定的，因此可以通过调整主排风风机的转速，使得负压隔离病房的救治间内的气压处于稳定状态，进一步地可以使得救治间的气压可以稳定处于救治间目标静压值。在本实施场景中可以获取救治间的救治间第二当前静压值，根据救治间第二当前静压值与救治间目标气压值，相应调整主排风风机的转速。
