Notes:
(1) Medical Data means heart rate, non-invasive blood pressure, SpO
2
, ETCO
2
, invasive pressure,
respiration rate and temperature with still photos and 12 Lead ECG recordings transmitted on a store-
and-forward basis and TCCC card data sent every 30 seconds.
(2) Waveforms means 1-2 channels of ECG, Plethysmogram and Capnogram and 1-2 channels of
invasive pressure.
(3) VOIP - Speex codec .
(4) Video - H264 format CIF image transmitted at 5 frames per second - this provides a low-bandwidth
video solution.
(5) Total rate is on a lossless data transfer; the bandwidth is likely to increase if data retry attempts are
required due to packet loss on the network.
