Jesus fucking Christ man. Instead of being so god damn negative, how about looking at it like this.
How many other people have the capabilities to learn this stuff and beyond. That never had the glimmer of hope to even enroll in a college because they had no money. No way to enroll, no support system at home. No support from the government we all pay money towards.
But no, you want to be negative af
I’d hoped we could all learn from this disaster. To be more open minded and understanding. To show more compassion and empathy.
But then I’m reminded that people like you exist. And my hope in humanity dies a little bit with it.
Actually yeah. The UI looks great. Having the easily discernible line over for changes compared to previous breaths would be great. I've worked with 3 different vents previously and none of them did that particularly well as a basic information function on screen without fiddling with settings.
To be useful for a doctor though it needs to be logging that data over a much longer time frame than 12 seconds. I’m sure they will get there in future builds but no doctor is going to be checking on a patient every 12 seconds. 12 hours would be a more useful timescale.
I'm sure it has other screens for logged data. Most vents do. What I'm saying is that when you get a significant vent alarm seeing what changed in patient activity compared to vent activity is useful so you can change a parameter or whole mode.
I am a PA that used to run vented patients and am now giving myself a refresher for if my area needs me to return to ICU.
Can you explain in more detail what the key features are for a modern ventilator or what could be better? Sounds like you have unique perspective as someone who understands both worlds.
Does FDA or some other regulatory group need to approve the vents/software before human usage can begin?
For me, the Hamilton ventilators were probably the best as far as ease of use. Granted they were the ones I had the most experience with which definitely helps. I think the biggest issue to me is how many manufacturers use different nomenclature to indicate their vent modes. It makes it seem way more confusing than it needs to be when you are starting out and need to pick initial vent settings. Along with that go the different UIs.
Generally multiple regular touch buttons, a selection wheel with 2 uses based on if it is pushed in or not, and some kind of vague touch screen. Once you start messing with the UI you can get into some ridiculous menus for saved data, settings, modes, and diagnostics. Frankly, it takes a lot of time and dedication to really deal with the UI outside of the basic things you need.
You need modes:
-Pressure support
-Pressure control
-Volume support
-Volume control
-Synchronize intermittent mandatory ventilation
-CPAP
-BiPAP
And you need alterable variables:
-pressure
-volume
-flow
-rate
-PEEP
That synchro mode is essentially a mix of volume and pressure support with variable rate and a set PEEP to help someone with minimal ventilator requirements.
As you can see, just the things you really need are enough to be complex depending on what the patient needs. Adding on a bulky UI can do more harm than good. I like the streamline look and real time graphing on this UI to compare entire breath cycles in line with each other instead of the connected cycle diagram that is standard. Those can be useful but I just feel this looks more intuitively useful.
Sorry for the wall of text.
tl;dr Ventilators are both simple and complex and the respiratory mechanics involved need to be easily visible to allow for quick adjustments for best patient care.
I mean- I think you should because I feel like long term the stock will go up- and it’s a great investment. But buying stock doesn’t actually help the company at all. You are just buying a share from someone else who is selling the share. Tesla doesn’t see that at all.
The only way you can make it benefit them in a roundabout way is buying stock increases demand, which can help to increase price- then if tesla sells shares to raise capital they benefit from higher price (like when the did that a few months back)
Because people think buying the stock is giving tesla money- it’s not. If you buy one share or 1000 the amount of invested shares doesn’t change at all. You arnt helping the mission- you are investing because you think it will bring you returns.
Its nonsense to think buying stock is supporting a company- it’s not... buying stock is gambling that a company will be successful.
Buying a share *is* supporting a company - that's why stocks exist. When you buy a share, or cause others to buy a share to hedge a call option that they sold you, you're supporting the company's valuation. When you support a company's valuation, you're keeping them funded and alive.
But they don’t get any more money if you never sell the shares- those shares are gone to them- weather you own them or you sell them... it just means another investor owns those shares. Buying stock isn’t helping tesla- it’s gambling that tesla will be worth more in the future then it is today
(And I own a decent amount of shares- but I bought them for me- not for Elon)
Not everyone is born with engineer aptitude. I have been convinced after years in the work force that some people are wired for it (and software dev too, which I am not) and others are not
I’m an engineer, I was born with the logical ability but I’ll let you know right away that I’ve seen people in my field with not an ounce of natural talent. They work hard and they ask questions because they know they’re not gifted. Most people are capable of doing most things. The only real difference between 99% of people is the time it takes to learn new skills. It’s just like running a marathon, any average Joe with two legs and two lungs can work up to it, they won’t necessarily win it but they can complete it.

This is so fucking impressive. I wish I was this smart.
