Before surgery,it is helpful to determine the patient's baseline inspiratory capacity.An inspiratory volume one half to three quarters of baseline is an acceptable postoperative volume.
The advantage of a flow-oriented IS is slow,steady expansion of the lung.Even if a very slow inspiration does not elevate the balls,this pattern helps the patient improve lung expansion.
