can you use pressure valve to release an air pressure into the water ? would that simulate a ballistic wave?

Probably they were choking, or in anaphylaxis. Not ARDS...Auto-Didact said:... let's just say I have given someone a new airway before in suboptimal conditions
Yeah, on the ICU and in the operating room for other reasons, definitely not ARDS. Of course, I wasn't sure what was the cause of suffocation and in a split second decision, it was the only treatment modality where something could still be done, so a necessary precaution to take which occurred automatically; if it was ARDS, it would be obvious upon observation and I'd still call it in after pulling something out of the utilityberkeman said:Probably they were choking, or in anaphylaxis. Not ARDS...
Anyway, I can lose my medical license if I try something like that. But that's a decision each of us has to make in disaster situations. Be well.

Dr. Courtney said:A sudden release of air in a pipe can simulate a air blast wave. Lots of shock tubes work on this principal, but it requires some length of pipe for the wave front to steepen into a shock wave. We tried this in water several months ago in a number of configurations. We could not get it to work. I'm sure a release of air at a high enough rate could simulate a blast wave in water, but one key is getting the shape of the overpressure wave to resemble a real blast wave in water rather than just the steep shock front followed by a noisy, poor wave shape. These experiments with pressure releases of air in water more-or-less led us to the current approach of firing spheres into water, which are working much better in terms of both wave shape and ease of use.

The research project continues in the basement, most recently creating underwater blast waves (ballistic waves really) by shooting a bb gun from Walmart into a 300 gallon stock tank.

Swamp Thing said:If it's ok to share the goal of the research, I'm sure many of us would be interested to know a bit more. I presume that some kind of nonlinear effects are being studied? I ask this because if they are only interested in propagation effects in the linear regime, then they could have used some kind of transducer to launch a pulse and then measure it at the other end.

Yes sure, sitting for a long time you can lose muscle. That is why I invent a need to go to the pharmacy which is the only non supermarket entity that is open. But then, I see all the people with masks who look like aliens in a horror movie, that makes me rush back to the safety of my home office.hagopbul said:run out of energy

Designing a machine to pull the moisture out of the aeoveli is difficult (because they are normally very flexible little air sacs), if possible at all. I think the best you could do would be to have some sort of dessicant presence in the ET tube (endotrachial tube) or other means to supply dry air, while still supplying O2 and evacuating CO2 effectively during ventilations. The goal would be to supply super-dry air to the lungs during respirator ventillations, to try to dry out the aeoveli over time.hagopbul said:can we desing a ventelator that can suck water from the lung using pulsed pressure difference in the lung that idea came to my after @Dr. Courtney basement experiments

Come to my flat! I had to have a plumber come and repair the outlet in the kitchen which leaked when the washing machine ran. Just testing it now for the first time...Stephen Tashi said:I'm replacing a sewer line:
