prevent the all-too-common problem of paralyzing residual neu-
romuscular blockade. The idea is to make quantitative train-of-
four monitoring as accessible as monitoring blood pressure or
oxygen saturation. The touchscreen monitor displays real-time
TOF count, TOF ratios and post-tetanic count, along with a time
plot of the patient's recovery over the duration of the case. The
company says the system's real-time data lets clinicians make
more informed, rational, cost-effective decisions on drug dosages
and reversal timing. To connect to the patient, a single-patient-
use electrode array attaches to an extremity. Because no physical
motion of the monitored site is required, TwitchView functions
reliably regardless of patient positioning, even when the arms are
tucked, which is a problem when using acceleromyography. It
comes with a pole mount and can connect to your facility's EMR.

This heart rate variability monitoring
device can be used for any type of sur-
gery. Its built-in algorithm is said to
help anesthesiologists evaluate the
high frequency component of heart
rate variability in all types of patients,
unconscious or conscious. The device
calculates an index by obtaining a
series of RR time intervals from the patient's ECG signal, filtering
them in real time. Then it re-samples the series and isolates it in
a temporary window, where it is normalized. All of that informa-
