Blackstone HS-820

Product Code: SATE-AAAME-3127

The Blackstone HS-820 is an anaesthetic workstation built around a 5.7-inch display and an integral ventilator. Four flowmeter tubes supply oxygen and nitrous oxide; one vaporiser position accommodates the volatile agent; tidal volume ranges from 50 to 1500 mL; and it offers eight respiratory modes with an I: E ratio of 4:1 to 1:10. Available from Medigear.uk.

One omission defines this anaesthetic workstation. The flowmeter block carries four tubes for oxygen and nitrous oxide, but not air. On the HS-850, five tubes cover three gases, including air. That lets an anaesthetist dilute oxygen with air and leave nitrous oxide out altogether. Here there is no such choice. Any anaesthetic needing a diluent must use nitrous oxide, because nothing else is piped in.

That has consequences beyond preference. Many British trusts have moved away from nitrous oxide on environmental grounds. Some have taken out the manifolds. Oxygen and air anaesthesia is ordinary practice. A machine unable to deliver it is restricted in a way no screen size or mode count makes up for, and that should be grasped before anything else on the sheet is weighed.

Three further differences separate this anaesthetic workstation from the larger machines. One vaporiser position rather than two, so changing agent means exchanging the vaporiser instead of turning to a second mounted unit—tidal volume starts at 50 ml rather than 20, which takes small paediatric work off the table. And pressure-controlled ventilation is absent from a mode list that otherwise runs to eight. Against those, one entry reads better here than on the bigger machine.

The I to E band is 4:1 to 1:10, the conventional range for an anaesthetic ventilator, and it makes the 1:8 to 1:10 printed on the HS-850 look more plainly like an error. Medigear.uk resolves the air supply question before this machine is offered.

Where nitrous oxide remains in routine use and cases are adult and straightforward, this anaesthetic workstation covers the work. Eight modes, including SIMV and PEEP, handle most general lists. A single vaporiser is sufficient where a department has standardised on one agent, and many have. A 5.7-inch display is adequate for an anaesthetist working at the machine rather than reading it from across the table.

Its limitations are defined by the gas supply rather than the ventilator. Without air, oxygen and nitrous oxide is the only mixture available, which rules out every case where nitrous oxide is contraindicated or simply unwanted, and there are many of those: bowel surgery, middle ear procedures, a suspected pneumothorax, prolonged cases, and any department that has taken a policy decision against the agent entirely. The absence of an anti-hypoxic interlock matters more on this machine than on one offering air. Nitrous oxide is the only thing being turned up as oxygen comes down, so nothing else dilutes the consequence.

Paediatric work is the other boundary. A tidal volume floor of 50 ml is not small enough for infants, where the HS-850 reaches down to 20 ml. This anaesthetic workstation therefore belongs on adult lists and should be specified as such. Capnography is not mentioned in any form, as on the standard HS-850, and it is required continuously in British anaesthesia.

Medigear.uk establishes the capnography arrangement, the hypoxic guard, whether air can be piped in at all, and the regulatory position before this machine reaches a theatre.

A Properly Published I to E Band

The conventional range is four to one through to one to ten, and it is stated more credibly here than on the larger machine in the same family.

Eight Modes on an Entry Machine

SIMV, IPPV, SIPPV, IMV, VCV, and PEEP, alongside assist control and manual, cover the general adult list without reaching the top of the range.

Simpler Gas Block

Four tubes across two gases means fine and coarse control on each, which suits a department that has standardised on oxygen and nitrous oxide.

One Agent, One Vaporiser

Where a department uses a single volatile agent throughout, a second mounting position is hardware paid for and never used.

Compact Display

At 5.7 inches, the screen occupies little of the machine top, which suits an anaesthetist standing at the workstation rather than reading it from a distance.

Full Manual Ventilation

Manual sits in the mode list alongside the automatic options, so bag ventilation remains available as standard.

Volume Control Retained

VCV appears in the mode list, so volume-controlled ventilation is available even though the pressure-controlled option is not.

Patient Monitor Available

An optional monitor can be specified alongside, which matters given what the machine does not integrate.

Display of 5.7 Inch

TFT, the smallest across the Blackstone range.

Built-In Ventilator

Integral to the workstation.

Eight Respiratory Modes

A/C, IPPV, SIPPV, IMV, SIMV, VCV, PEEP and Manual.

Tidal Volume 50 to 1500 ml

Thirty millilitres above the HS-850 at the lower end.

I to E Band of 4:1 to 1:10

The conventional span for an anaesthetic ventilator.

Four Flowmeter Tubes

Oxygen and nitrous oxide, with no air.

One Vaporiser Position

Taking a single volatile agent at a time.

Optional Halothane Vaporiser

Supplied separately where required.

Optional Patient Monitor

Available alongside the workstation.

No Pressure Controlled Mode

PCV is not listed in the published mode list.

Judged on the ventilator alone this anaesthetic workstation is a reasonable entry machine: eight modes, volume control, PEEP, and an I to E band published more convincingly than the one on its larger sibling. The limitation is the gas block. Air is not plumbed in, so nitrous oxide is the only diluent available, and any department that avoids nitrous oxide or has decommissioned it cannot use this workstation for routine anaesthesia. That single fact should be settled before discussing screen size, vaporiser count, or mode list. Two further boundaries apply: tidal volumes above 50 ml put infant work out of reach, and pressure-controlled ventilation is absent. Capnography, inspired oxygen monitoring, the anti-hypoxic interlock, and conformity marking are all unaddressed across this range. Medigear.uk resolves them before quoting this anaesthetic workstation.

FAQ

Frequently Asked Questions

Everything buyers need to know about sourcing medical equipment through MediGear.

Because it removes a choice an anaesthetist normally has; with only oxygen and nitrous oxide, any case needing a diluent must use nitrous oxide. Oxygen and air anaesthesia is ordinary practice, and several British trusts have moved away from nitrous oxide entirely, so this restricts where the machine can work.

Four ways separate this anaesthetic workstation from it. The screen drops to 5.7 inches, air leaves the flowmeter block, one vaporiser replaces two, and tidal volume starts at 50 ml rather than 20. Pressure-controlled ventilation is also absent from the mode list. The I to E band, though, is published more sensibly here.

Not for small children. Tidal volume begins at 50 ml, where the HS-850 reaches down to 20, so infant work is outside this machine's published range. It is an adult workstation, and any department needing both adult and infant capability should look at the larger model instead.

The vaporiser is physically exchanged, since only one position is fitted. On a two-position machine, an anaesthetist turns to the second mounted unit instead. For a department running a single agent, that makes no difference; for one alternating between agents, it means handling hardware between cases.

It reads more plausibly. This sheet gives 4:1 to 1:10, which is the conventional band for an anaesthetic ventilator. The HS-850 prints 1:8 to 1:10, sitting wholly at the expiratory end, and seeing the full range on the entry machine makes that figure look more clearly like a misprint.

Nothing describes one, and the question carries more weight here than usual. Where nitrous oxide is the only diluent, it is the only thing being increased as oxygen is reduced. Hence, an interlock preventing a hypoxic mixture matters most. We establish it before supply.

The sheet does not mention it at all. Continuous capnography is required in British practice from induction to recovery, so whether this machine takes integrated monitoring, or whether a department must run it alongside, is settled before supply.
