Why the study?
Does the use of a random-zero machine and varying cuff sizes improve blood pressure measurement accuracy in children compared to a standard sphygmomanometer?
Population

Supports random-zero machines to reduce observer bias in pediatric BP; leaves open direct comparability to standard devices and cuff correction validation.
Does the use of a random-zero machine and varying cuff sizes improve blood pressure measurement accuracy in children compared to a standard sphygmomanometer?
The random-zero machine is preferable for pediatric blood pressure measurement to reduce observer bias, and cuff size effects can be mitigated by using the largest fitting cuff with a correction factor.
