Single modules require a unique slot, directly connecting it to the monitor or in the PAM unit. Simple modules are the following:

· V-SpO2: Nellcor SpO2 module

· V-CO2: mainstream Respironics module

· V-AG: Masimo anesthetic gases (AG) module

· V-CO: Cardiac Output (CO) module

· V-IBP: IBP module with two channels. You can acquire 3 of these modules for simultaneous monitoring of up to 8 IBP channels, considering those in XM module

· V-BIS: Bispectral Index (BIS) module

· V-ICG: Impedance Cardiography (ICG) module

Double modules require two slots at the same time, meaning you could connect two simple modules instead of a double one. Double modules are:

· V-NIBP: SunTech NIBP module

· V-AG: sidestream Masimo anesthetic gases (AG) module

· V-AG: sidestream Drager anesthetic gases (AG) module

· V-CO2: sidestream Respironics module

· V-CO2: sidestream LIFEE module

· V-RM: Respiratory Mechanics (RM) module
