4. TrueTime 4 TrueTime is a Matlab/Simulink-based simulator for real-time control systems. Written in C++ MEX Network block (Ethernet, CAN, TDMA, FDMA, Round Robin, Switched Ethernet, FlexRay and PROFINET) Wireless network block (802.11b WLAN and 802.15.4 ZigBee) 2010-07-16 TrueTime 2.0 beta 6 has been released.

8. Network Model for Pulmonary Vascular Resistance (PVR) 8

9. PVR is the resistance in the pulmonary vascular bed against which the right ventricle must eject blood. To calculate the pulmonary vascular resistance, the patient monitor needs to know: 1. left atrial pressure (LAP) 2. pulmonary capillary wedge pressure (PCWP), 3. pulmonary artery pressure (PAP), and 4. cardiac output (CO). PCWP provides an indirect estimate of LAP. 9 Key Points:
