To clarify there are different types of ventilation where ventilation means to assist the delivery of oxygen to a patient.
Non-invasive Ventilation (NIV)
Without significantly increasing pressure in the airways
high flow nasal cannula
Positive airways pressure
Negative Pressure Ventilation
If you are just starting with a whole bunch of patients that are on mechanical ventilation, then you have identified a cohort and you aren't doing case-control.
However, this sounds like it could be case-control approach if you approach and analyze it as such. In a case-control approach, you identify cases by some outcome measure, and take controls from a ...
I don't see that we can have that data yet, nor can it be answered simply. In Wuhan, Italy and New York when ICUs were being overwhelmed with patients, and there was a ventilator shortage, then only the most sick were being invasively ventilated, and others were left to die. Or, ventilators were split so that each patient shared the same settings which is ...
When patients have respiratory problems due to low oxygen saturation then you can supplement the O2 of room air by using high flow oxygen at various concentrations above room air using nasal cannulae or masks such as a Hudson mask.
When they are unable to maintain adequate oxygenation levels with a mask, and/or suffering respiratory muscle fatigue, they are ...
Obviously depends on the exact case at hand, but from what I know, non mechanical ventilation (ie. Venti mask, etc.) Is only used for very mild ARDS where there is fairly good oxygenation and the patient is hemodynamically stable (good blood pressure and heart rate), able to keep their airway open, no copious secretions, etc. (https://www.ncbi.nlm.nih.gov/...
I finally found the symbol on page 5 of the quick reference guide (http://nippyventilator.com/wp-content/uploads/2015/07/NIPPY-Junior-Quick-Reference-Guide.pdf) for the ventilator. It is just an indicator that the disconnect alarm has been set to low sensitivity.
Ventilator-associated events" (VAE) are complications (infections and others) that usually need additional treatment, so they are usually associated with prolonged ICU "length of stay" (LOS). But someone with more severe initial condition without VAE may stay in ICU for longer than someone with a milder condition + VAE.
Poor outcomes after mechanical ...
Placing bacteria filters on the tubing would be my go-to practice (I am a retired RT) but that seems ineffective since Viral load is much smaller than the sub-micro bacterial load the filters are designed for.
It’s a wet sloppy job ~ I had 35 years experience and I won’t gloss it over.
Sorry, I have no practical advice for front-line workers beyond good PPE, ...
Why aren't lung machines / ECMO widely used for COVID-19?
They are being used University of Michigan and News Medical
Beyond that, you have already suggested the "why" not being used more widely, there are far fewer ECMO devices than ventilators.
The remark about insurance companies is an inappropriate speculation.
The latest data on using Partial Liquid Ventilation (Total Liquid Ventilation has been shown to be unsustainable) was from a 1996 study
Hirschl et al. treated 10 adults who had acute respiratory distress syndrome (ARDS) and reported a decrease in the physiologic shunt and an increase in pulmonary compliance; 50% of the patients survived in their study. ...
China has sent 67 ECMO machines to Hubei, said Luo Junjie, an official from the Ministry of Industry and Information Technology, adding that the ministry will import more ECMO machines for Hubei and Wuhan, the capital city of the province.Mar 4, 2020
this doesn't tell how many ECMO machines ...
You're asking for the result of a trial which hasn't been conducted yet. I suspect it's not possible to delay permanently intubation just by inspiratory muscle training given that in Italy patients were intubated for about 15 days
About 15 days are necessary to achieve effective weaning from respiratory care in ICU. Indeed, the experience shows that ...
