The K4 software is PC compatible (except for Windows 10 S for which it is not compatible).
It is also MAC compatible, working on the following MAC OS. Mac software will only work for x86_64 bit architecture.
POWERbreathe is a scientifically proven Inspiratory Muscle Training (IMT) device, developed by leading scientists for improving the strength and endurance of the muscles used to breathe in, primarily the diaphragm and intercostals / rib cage muscles.
As with any other muscle, respiratory muscles can be trained so that they are more resistant to fatigue. This resistance to fatigue results in reduced breathlessness and enhanced exercise tolerance.
Breathing physiology indicates that when your lungs are empty the breathing muscles are at their strongest. However, as they fill up with air they start to lose strength and therefore at high loads they can’t maintain a full contraction throughout an entire breath.
The POWERbreathe K-Series uses Electronic Variable Threshold Resistance Training to overcome this. This type of training offers a tapered loading resistance to match the contraction curve of your own breathing muscles throughout your entire breath. This enables you to complete a full breath and muscular contraction at an optimal resistance.
The K-Series will automatically adapt to increases in your inspiratory muscle strength at the beginning of each training session.
This study concluded that the K-Series device "provides automatically processed and valid estimates of physical units of energy during loaded breathing tasks..."
This study suggests that S-Index might be more appropriate for measuring inspiratory muscle performance than the currently most used test, PImax...
Full instructions are provided in the User Manual. Quick Start:
Your POWERbreathe will be exposed to saliva during use. We recommend that a few times a week you remove the valve head with mouthpiece and soak it in warm water for about 10 minutes (see POWERbreathe Manual for full details), but once a week soak the valve head with mouthpiece in a mild cleansing solution instead of water, using POWERbreathe Cleansing Tablets - only 1 tablet is required each time.
DO NOT immerse the handset or expose it to running water as this will damage the electronics.
POWERbreathe is drug free, suitable for almost anyone and should cause no harmful side effects when used properly. Please read the following precautions and contraindications to ensure that you use your POWERbreathe safely and appropriately.
If you have any doubts about POWERbreathe’s suitability, or you have a medical condition, please consult your doctor.
Inspiratory muscle training, such as training with POWERbreathe, is not recommended for patients with certain conditions, including the following:
