Glossary

Quick definitions for every TMA-specific term.

• AED Trainer — The Display Monitor panel that simulates AED operation (Standby → Attach Pads → Analyze → Shock). Enabled via Display Controls on the Controller.
• Apply New Vitals — The Controller button that pushes staged numeric values from the New column to the Display Monitor. Nothing numeric changes on the Display until this is clicked.
• AUTO (BP) — The auto-cycle mode for NIBP. Cycles through OFF, 5 min, 10 min, 15 min. When active, automatically takes a BP reading at the chosen interval.
• Battery — The simulated monitor battery. Drain mode depletes at 1%/min; Charge mode adds 5%/min. At 0%, the Display Monitor shows DEVICE OFF.
• Controller (screen) — The instructor remote at /controller. Where you change vitals, rhythms, alarms, and all session settings.
• Controller (permission) — A user who can access both the Controller screen and the Display Monitor, and can manage other users.
• Crisis Alarm — Red alarm. Fires when a vital is out of range for 5 or more seconds. Outlines the affected vital in red on the Display Monitor.
• Current column — The "what is currently displayed" column in the Vital Values table. Reflects the last Applied value.
• DEVICE OFF — The state of the Display Monitor when battery reaches 0%. The screen goes dark until the battery is charged above 0% via the Battery tab.
• Display Controls — A modal on the Controller with toggles for: Display Monitor on/off, AED Trainer on/off, Rhythm Identification on/off, NIBP Auto Cycle on/off.
• Display Monitor (screen) — The student-facing patient monitor at /display. Shows ECG, SpO2, EtCO2, BP, Temp, Glucose, and more.
• Ectopy — Extra beats overlaid on the underlying rhythm. Options: Monomorphic, Polymorphic, None.
• End Trend — Stops an active trend immediately. Vitals stay at their current mid-trend value and do not revert.
• Immediate Apply — The default Apply mode. Vitals change instantly when Apply is clicked.
• INOP — "Inoperable." A simulated sensor disconnect. The affected vital shows dashes (---) and an INOP alarm fires.
• MAP — Mean Arterial Pressure. Auto-calculated from Systolic and Diastolic BP.
• Multi-Session Controller — The ability for one Controller to manage multiple simultaneous sessions from one device, switching via the session dropdown.
• New column — The "what is staged" column in the Vital Values table. Reflects what the instructor has set but not yet Applied.
• NIBP — Non-Invasive Blood Pressure. TMA's BP model: values are hidden until measured by pressing the NIBP button, mirroring how a real NIBP cuff works.
• Original Owner — The user who created the session. Has permanent Controller access and cannot be demoted or removed by anyone.
• Patient Population Preset — Pre-configured alarm thresholds for an age band. Options: Adult (≥13), Pediatric Infant (1–12 months), Pediatric Child (1–7 years), Pediatric Adolescent (8–12 years), Neonatal (0–28 days), Custom.
• Pleth — Plethysmograph. The SpO2 waveform displayed on the monitor.
• Pleth Amplitude — Height of the pleth waveform (0–100%). Lower values simulate weak peripheral perfusion.
• Pleth Morphology — Shape of the pleth waveform. Options: Normal, Bisferiens, Pulsus Alternans.
• PTT (Pulse Transit Time) — Delay between the ECG R-wave and pulse arrival at the SpO2 sensor. Normal: 200–300ms. Longer = low perfusion/shock. Shorter = arterial stiffness.
• QRS Beep — An audio heartbeat tone played after each QRS complex. Toggle in the Audio tab.
• Rhythm Identification — The on-monitor label naming the current rhythm (e.g. "Sinus"). Toggle off in Display Controls to quiz students.
• Session — The container for one simulation. Holds all vital values, rhythm, alarm settings, battery state, user list, and the Session ID. Server-authoritative.
• Session ID — The short alphanumeric code identifying a session (e.g. K1KYW1). Case-insensitive. Never contains O or 0.
• Shock Outcome — The rhythm the patient converts to when the AED Trainer delivers a shock. Set on the Controller; options include No Effect, Normal Sinus, Sinus Tachycardia, V-Tach, V-Fib, Asystole.
• Silence (button) — On the Display Monitor, temporarily silences the currently sounding alarm. The next new alarm will still sound.
• SpCO — Carboxyhemoglobin. Displayed when set above 0. Used for CO poisoning scenarios.
• Trend Apply — An Apply mode that animates vitals from current to target over a chosen duration (3–300 seconds) rather than changing them instantly.
• V/NV — Visible / Not Visible toggle per vital on the Controller. NV hides the vital from the Display Monitor entirely — the cell appears blank.
• Viewer (permission) — A user with Display Monitor access only. The Control Vital Signs tab is hidden from their header. Read-only.
• Vital Values Table — The two-column table on the Controller showing Displayed (current) and New (staged) values for every vital.
• Warning Alarm — Yellow alarm. Fires when a vital is out of range for 10 or more seconds.
• Welcome Back modal — Appears on return visits when a previous session is still active. Offers to Continue Previous Session or Start New Session.
