Hey all, I have a L063-05R Allied Demand Valve (40lpm) and I'm having some success in aborting quickly using it but I can't shake this feeling that I'm doing something wrong
If I inhale as quickly as is needed for me to perform ~30 full breath cycles, my demand valve makes a fluttering noise as if I'm pulling air from around the 'exhale flaps' of the demand valve. If I inhale a little slower it doesn't make that noise but I'm doing fewer cycles. Am I overthinking it? For reference, I'm a pretty tall guy at 6'5 so maybe my lung capacity makes ~30 cycles unnecessary (or not feasible!)
Are there any video demonstrations of using a demand valve to compare?
