One last thing! Anesthesiologists ❤️ safety so make sure .🚨 Alarms are loud enough to hear.🖥️ Directly monitor the patient if using a support mode.🛑 Don’t add a neb without checking with manufacturer .☎️ Call 1-800-BAG-1001 to reach a real life Anesthesiologist! (10/11).

We started off asking how long you’d used an anesthesia machine for a case. Anesthesia machines need to be calibrated at least every 24h. You can go longer, but risk less accurate pressures and volumes. Most machines also have a limit at which they shut down (~40-60days) (9/11).

Now how to use an anesthesia vent in the ICU? 1) Get the machine there, connect electricity, gas, and power. 2) Get your filters and circuit set up. 3) Run the appropriate checks. 4) Remove the waste gas connectors so you do not get unintentional PEEP. (8/11).

Speaking of filters, can we minimize transmission of COVID-19? Yes! Place 2 filters in series. One at the ETT and one at the exp limb of the vent. This filters sampled and exhaled gas from viral particles- improving reliability and safety, an anesthesiologist’s hallmark! (7/11)

What does HMEF stand for? Heat and Moisture Exchanging Filter. These simultaneously preserve heat and moisture in the patient while providing COVID-19 filtration. An approved list can be found on the APSF website ( (6/11).

To circumvent this problem, the APSF recommends setting the FGF to at least minute ventilation (~6-8L/min). Combined with an HMEF at the airway, this minimizes humidity in the circuit while preventing rebreathing and the overuse of CO2 absorbent. (5/11).

More importantly, anesthesia ventilators allow rebreathing of exhaled gas and alteration of fresh gas flow (FGF). This means more monitoring and upkeep, as well as the possibility of excess humidity in the circuit and more filter clogging if low FGF is used. (4/11).

For one, an anesthesia vent delivers breaths in CONTROL mode, patients aren’t allowed to trigger their own breaths unless Pressure Support is added. ICU vents use Assist Control mode, where breaths are triggered by the machine and/or the patient. (3/11).

One might wonder, if an anesthesia machine has a ventilator in it, how is it different from an ICU ventilator? Think of it as a Mercedes AMG GT63 vs a Honda Civic. Both serve similar purposes, but one can do a whole lot more than the other. (2/11)

To start things, there’s a lot of talk about using an anesthesia machine to save a COVID patient’s life; and in a ventilator crunch, that may definitely be the case. For the anesthesiologists out there, what’s your record for the longest case you’ve used a single machine? (1/11).
