Substantial tonometry variation cautions against clinical reliance on calibrated readings; leaves open needs for refined validation versus intra-arterial standards.
Does the Colin tonometry module accurately measure blood pressure compared to intra-arterial measurement in conscious patients?
The Colin tonometry method is insufficiently accurate for clinical practice due to errors introduced by its oscillometric calibration.
Hansen et al. (2006) studied this question.
