ASV (Adaptive Support Ventilation) with the Hamilton Ventilator

Here is a video I produced for Adult Retrieval Victoria on Hamilton’s proprietary intelligent ventilation mode, ASV, using the Hamilton T1 Ventilator, but it’s applicable to our Hamilton C1.

Please do not distribute, as these videos are AV property.


ASV takes into account the patient’s respiratory mechanics, which are measured breath-by-breath by the proximal flow sensor. ASV ensures optimal ventilation for each patient during passive ventilation but also has automatic adjustment in spontaneously breathing and weaning patients.

In passive patients, ASV is a volume-targeted pressure controlled mode with automatic adjustment of inspiratory pressure, respiratory rate, and inspiratory/expiratory time ratio. Maximum tidal volume is controlled by setting a maximum inspiratory pressure. Expiratory time is determined according to the expiratory time constant in order to prevent dynamic hyperinflation.

Hamilton Ventilator Education

Here are some videos I produced for Adult Retrieval Victoria, using the Hamilton T1 Ventilator, but all are applicable to our Hamilton C1.

Please do not distribute, as these videos are AV property.


To begin please watch the videos linked below produced by Hamilton to familiarize yourself with the Hamilton T1:

Device Overview

Setup and Preop Checks

User Interface

Basic ventilator settings

Alarm Management


Then watch the following videos, together with the Initial Setup & Troubleshooting Guides below:

Initial Setup:


Idiosyncracies of the Hamilton:


walking through the central line

we discovered at registrar training last week that many of our team had not placed a central line so here is a walk through the process….




Why does the patient need CVC – access, multiple lumens, centrally active medications, monitoring

Where should the CVC go – IJ, subclavian, femoral

Position – complications to lying flat, Trendelenburg, sedation/intubated

Potential complications – bleeding, pneumothorax, failure

Consent the patient – procedure, options, complications (pain, allergic reaction, bleeding, pneumothorax, infection, failure, neuropraxia)



Set it up yourself

US – cover, sterile gel, positioning

Procedure tray – large area

Dishes – antiseptic wash, saline, disposing sharps

CVC kit – introducer/seeker, guidewire (check glides, some unwrap but care doesn’t become unsterile), dilator, CVC – check each lumen/leave brown uncapped, caps, adjustable hubs)

Syringes – 5ml for local, 20ml for saline + needles


Gown, gloves, mask, goggles, drapes

Suture material and instruments

Local anaesthetic

Antiseptic skin wash

Clear dressing to fix line



Team – performing clinician, assistant, supervising doctor, backup

Monitoring of patient – ECG (BP + Sats if sedated)


Nurse in charge aware



Check vein with US first – position, anatomy, thrombus

Position patient/US/procedure tray/staff to monitor

Scrub hands, glove + gown

Wash patient + drape – large sterile area

Draw up LA

Position equipment in order of use so easy to reach

Check CVC lumens with saline flush + leave brown lumen uncapped

US to identify vein

50mg lignocaine with adrenaline into skin

Seeker needle with saline in syringe, using US in longitudinal to guide and cannulate vein

Hold with other hand to fix position on skin

Remove syringe

Feed guidewire, remove needle

Confirm position of wire with US before dilating

Dilate vein

Feed CVC with one hand always holding guidewire (care that wire does not become unsterile), depth determined by line markings 10-15cm – confirm ECG trace

Remove wire – announce to staff to document

Aspirate and flush each lumen before capping

Fix to skin with hub (clamp and fastener)

Suture 4 points (hub and distal) position

Cover with clear dressing

Confirm position with CXR

Dispose of sharps/wire and biohazard material


Aseptic technique


Local anaesthetic

Vein cannulated – number of attempts

Guide wire inserted, vein dilated, CVC inserted, GUIDE WIRE REMOVED, fixed at “x”cm


Confirmed with CXR – position in SVC at junction with RA (level of right main bronchus), no pneumothorax
