Overview
The Lab starts with Essentials: two ECG leads, arterial pressure and breathing, plus rate and BP cards. Use the view selector for Cardiac mechanics, Right heart or Full workspace. These views change the display, not the patient.
Open Add traces & tools. Shaded buttons are on; click or tap to toggle. Waveforms groups the pressure and ECG channels. Studies contains echo, PV loops, Chest X-ray, Catheter pullback, thermodilution and Fick. Show all and Hide all apply to both tabs. Summary opens the hemodynamic table. The overlay starts empty on a common pressure scale.
Catheter focus sits with the right-heart pressures. RA, RV, PA or PAWP isolates and enlarges that chamber trace; All chambers restores the four channels. These shortcuts leave the other waveform and study selections unchanged.
Balloon channels appear only when the pump is active. A guided teaching case also limits which data have been revealed; showing all cannot reveal a future stage.
