The phrase "act measurements" is not correct in standard written English.
It seems to be a misunderstanding or a typo, as "act" does not typically pair with "measurements" in a meaningful way.
Example: "The act measurements were taken to ensure compliance with safety standards."
Alternatives: "performance measurements" or "action measurements."
Because activated coagulation time (ACT) measurements may not be accurate during CPB, the use of a heparin management system (HMS) has been advocated.
There were 183 paired APTT and ACT measurements done at the same time (29 patients).
The purposive sample was based on a maximum variation principle, using the following characteristics: age, gender, region, PRISMA-7 score (a brief 7-item questionnaire containing risk factors for functional decline [ 35– 37]), and, if participating in ACT measurements, educational level, presence of unmet social care needs, presence of chronic disorders and self-reported health and QoL.
The present study focused on the inter-device and intra-device differences (for example, reproducibility of ACT measurement) in four different ACT measuring systems.
Baseline ACT measurement from an introducer should be obtained before placement of the HPAC.
Therefore, the authors determined the relationship between AT and other coagulation-related factors that affect the ACT measurement and heparin sensitivity index before the establishment of cardiopulmonary bypass.
Reproducibility of ACT measurement (for example, intra-device difference) was, in descending order, best for Hemochron Junior, Actalyke ACT-Max, Hemochron celite and Aktalyke celite.
It has been stated that the effect of heparin is inadequate in the paediatric population if detected by ACT measurement [ 22].
ROC curve analysis confirms high specificity and sensitivity of the ability of urinary α1-ACT measurement to discriminate sCJD status.
The ACT values measured simultaneously using four different ACT measuring devices did not correlate with each other at any measurement time.
By contrast, in nonlinear contexts, where linear superposition fails, a full specification of an instantaneous state of the system plus the equations of motion does not yield all the information there is about the system, for example, if there are memory effects (hysteresis), or the act of measurements introducing disturbances that SDIC can amplify.
