How can the amount of cuff volume/pressure lost in the connecting tube be minimized during cuff measurement using a three-way stopcock,a manometer,and a syringe?
A) Using a four-way stopcock
B) Overinflating the cuff prior to measurement
C) Simultaneously inflating the cuff and manometer
D) Pressurizing the manometer to 25 mm Hg prior to use

Pressurizing the manometer to 25 mm Hg before measuring the cuff pressure will ensure that the pressure/volume in the cuff will not be lost into the connecting tubing.Once pressurized,the three-way stopcock,syringe,and manometer system can be inserted into the pilot.With all three ways open,the cuff can be inflated or deflated while the pressure is being measured.
