Hamilton T1 — How to Use

What You're Looking At (Current Screen)

⚠️ Active alert: "Battery 2: Replacement required" — the backup battery needs replacement. Connect to AC power (the AC icon is shown at the bottom right of the display).

Starting Ventilation — 6 Key Steps

1. Press one of the three Quick Setup buttons (on the touchscreen) — these auto-populate settings based on patient type.
2. Select Male or Female — the ventilator uses sex to calculate Ideal Body Weight (IBW).
3. Set Patient Height — use the Press-and-Turn knob (the large green dial on the right side). The ventilator calculates IBW from height and sex, which drives startup settings.
4. Select the Mode — tap the "Modes" button (top right of screen). SIMV+ is the default. Other common options:
   • CMV+ — equivalent to Assist Control/Volume (recommended for most ICU/transport patients)
   • PCV+ — pressure-controlled
   • ASV — adaptive support ventilation (auto-adjusts to patient effort)
5. Review Controls and Alarms — tap the "Controls" button to adjust Vt, RR, PEEP, FiO₂, I-time; tap "Alarms" to set limits.
6. Touch "Start Ventilation" — confirm to begin.

Adjusting Settings

• Tap the parameter on the touchscreen to select it
• Turn the knob to adjust the value
• Press the knob (or tap "Accept") to confirm

• Vt — target tidal volume (aim ~6–8 mL/kg IBW; lung protective = 6 mL/kg)
• RR — respiratory rate
• PEEP — typically 5 cmH₂O; higher in ARDS
• FiO₂ — start at 100%, wean as tolerated
• I-Time — sets inspiratory time; the I:E ratio is NOT set directly — it changes automatically when you adjust RR or I-time. If you increase RR, manually adjust I-time to maintain your target I:E ratio (e.g., 1:2)

Ventilation Modes Explained

Standard Initial Settings (70 kg adult)

Navigation Buttons (Screen Bottom)

• Monitoring — live waveforms (Paw = airway pressure in yellow, Flow in pink/magenta as shown)
• Tools — advanced calculations, lung mechanics
• Events — log of alarms and events
• System — ventilator settings, screen brightness, battery

Physical Buttons (Right Side Panel)

• Power button (top right, green ring)
• FiO₂ quick increase (↑O₂ button — press for rapid 100% O₂ for 2 minutes)
• 2 MIN button — manual 2-minute 100% O₂ flush
• Alarm silence — triangle/bell icon

Important Tips

• Always set patient height and sex first — this determines IBW-based default settings.
• If the patient deteriorates: disconnect and manually bag with 100% O₂ while troubleshooting.
• The T1 has an online simulator for practice — excellent for familiarizing yourself with the interface before clinical use.
• The full Hamilton T1 Operator's Manual is available from Hamilton Medical directly.
