Some people don't think masks are necessary because Dr. Debbie Birx says they are not needed. You make a great point, sneeze into your arm but dont sneeze into a mask. It's a very novel (get the play on words) idea that Dr. Debbie has trouble grasping.
Not a bad idea. Unfortunately this type of delivery system has several flaws. AMBU bags are good for the short term until mechanical ventilation is procured. Short term is measured in minutes here...maybe an hour or few if necessary. One, ventilation over the longer term requires biofeedback from the patient and two, the ventilator needs to deliver precise amounts of oxygen (measure in different ways) and the ability to measure the percentage of oxygen delivered. Done incorrectly over the long term for most of the settings, even slightly miscalculated ones, can lead to detrimental and/or disastrous results.
My guess is this design could do most/all of that, but not 100% sure; controlling pressure and flow of a gas is pretty damn easy and the logic for feedback from a probe in the patient ought to be able to be incorporated into the control loop logic for that pressure/flow (I did some similar things 30+ years ago in grad school). But yes, done poorly would be bad.
You used cloth diapers 100% right? All kidding aside, I did a real quick search and found two interesting tidbits. One, I might know the CEO of one of the companies and two they use hydrogen peroxide to sterilize the masks.
Hydrogen peroxide:
* can cause upper airway irritation, inflammation of the nose, hoarseness, shortness of breath, and a sensation of burning or tightness in the chest. Exposure to high concentrations can result in severe mucosal congestion of the trachea and bronchi and delayed accumulation of fluid in the lungs.
* Inhalation or ingestion of high concentrations of hydrogen peroxide may result in seizures, cerebral infarction, or cerebral embolism. The ensuing damage to the CNS may cause permanent neurological deficits or death.
****Sign me up for some of that.........................NOT!! As Borat said.
Not sure why anyone would use peroxide, when dry heat works. 140F for 30 minutes works (115F deactivates the virus very quickly) and doesn't hurt the mask.

Possibly...the procedure is uncomfortable, but for the most part tearing of the eyes is by far the most uncommon result. Surprisingly, the gag reflex is pretty much absent as the swab touches areas above the gag location.
You are more than welcome to reuse a gown, gloves or mask that has just taken care of a patient who has a deadly virus, drug resistant organism, incurable disease, tuberculosis, etc. And you are triple welcome to reuse them if they are splashed on, smeared on, coughed on, or just plain soiled. Just please dont include us healthcare workers.
Soap and warm water will absolutely deactivate the virus and is the method of choice for everyone's hands, so not sure why gowns couldn't simply be laundered in warm water and dried, unless they wouldn't stand up to those conditions.
You picked the healthiest subset as a representative sample? That doesn't make sense.
