Non-Invasive Ventilation (NIV) on the Hamilton T1

Last updated 23/07/19

Definition

Application of Non-Invasive Ventilation (NIV) using the Hamilton T1 ventilator

Features

Mandatory breaths: pressure control ventilation as backup apnoea mode
May be used to pre-oxygenate for Rapid Sequence Induction (RSI) and then switch to ventilation

Equipment

Hamilton T1
Face mask + straps
Circuit
+/- Oxygen supply

Will only achieve FiO2 of 0.21 on room air via inbuilt impella

Procedure

Select Adult/Ped. or Neonatal (for nCPAP)
Select gender and height
Select Mode

Select NIV for Continuous Positive Airway Pressure (CPAP) or Bilevel Positive Airway Pressure (BPAP)
Select NIV-ST (Spontaneously Timed) for BPAP only (cant set 0 Pinsp)

Set pressures

Pressures are additive

Set Psupport (NIV)/Pinsp (NIV-ST) = the pressure added to PEEP to create Inspiratory Positive Airway Pressure (IPAP)
Set PEEP = Expiratory Positive Airway Pressure (EPAP)

CPAP

Set PEEP to desired level = CPAP
Set Psupport to 0cmH2O

BPAP

Set PEEP(EPAP) to desired level
On NIV mode set Psupport to additional pressure required to make desired IPAP ie: IPAP - PEEP
On NIV-ST mode set Pinsp to additional pressure required to make desired IPAP ie: IPAP - PEEP

Note that this cannot be set <5cmH2O and cannot be used for CPAP

Set Oxygen (FiO2)
Press Start ventilation

T1 NIV
CPAP on NIV at 10cmH20 PEEP (EPAP)

T1 NIV
BPAP on NIV-ST at 15/10cmH20: (IPAP/EPAP)

Further setup

Assess Leak

Select Monitoring then Values

Select 2
VLeak = leak
Target <20%

Leak

Determine oxygen consumption

Needs consideration if transporting patient
Select System then Info

O2 consuption

Set backup ventilation

In NIV mode select Controls then Apnea

Can select backup mode PCV+/SIMV+ on/off
Select settings as required or check Automatic

Pinsp + PEEP = Pcontrol = Pressure Control Ventilation (PCV)

In NIV-ST mode select Controls then Basic

Set Rate
Pinsp + PEEP = Pressure Control Ventilation (PCV)
