I would like to know any instrument to measure cost-effective those outcomes. If it could be not more of two of them. I think spirometry could give almost all of them, but I'm not sure abaout pimax and pemax. Thanks for your help.
The only possibility to have those ouycomes in one unit is to use a setup like Jaeger's MasterLab plethysmographs. It includes measurements of TLC and subdivisions, spirometry in standard, and measurements of repiratory maximal pressures as an option.
You can add a MicroRPM device to the spirometry measurements (of volumes & flows) in order to measure MIP/MEP and Sniff pressures ( it means you nedd 2 devices: spirometer & microRPM device)
PowerBreathe have some kind of device & software which combines MIP measurements and very partial spirometry (I think POWERbreathe K5 + Breathe-Link PC Software...), but you won't get a full spirometry measurements with this device..
I'm doing a research protocol about respiratory muscle training and I was thinking about using the powerbreath device but this only gives me the chance to train inspiratory muscle. Also, I found the powerlung device, this one can train inspiratory as well as espiratory muscles at the same time, but it's difficult to find some evidence that validate this device.
Do you know about any other device that I could use to train both muscles?
Medical Graphics Corporation, CareFusion (Jaeger), Medisoft and also a Spanish company SIBEL that provide a Spirometer together with MIP and MEP (see link)
