Does my K-Series model ever need re-calibrating for maintaining accuracy?

It really varies based on the User i.e. Medical, Trainer, Private Individual, and personal needs.

We offer the Calibration Service to meet the needs of the respective Groups. Medical generally require all equipment to undergo an annual calibration, as they rely very much on the data. Private individuals may also wish to have this service for peace of mind in the knowledge that their device is functioning correctly. However, due to Calibration being a chargeable service, you may choose not to.

Certainly KH2, KH1 products designed for Medical Markets should be calibrated annually.

In Auto mode, will it increase automatically though the levels from V.Light to V. Heavy as I improve?

These levels are more like “Intensity” levels so once you are comfortable with working at the V.Light intensity and/or your improvement appears to flat line with little or no improvement, then you Manually increase the intensity of your work out to Medium for example.

Each time you use your POWERbreathe, your first two breaths will calculate your optimised working level (Auto-optimising feature). This will step incrementally over the next three breaths to your training load for the session, and is based on the level of intensity you have manually selected.

The most important message is to ensure that you can maintain your 30 breaths for the session, if the Level or Intensity is too high then you will find that the session will be short and you are training to fail. Consider as a comparison: Weight lifting as an example – the incomplete Arm curl or doing half completed repetitions within a set – It is more important to complete those 30 reps.

What’s the difference between KH1 and the K5?

The KH1 is a medical device and includes features and results for more medical requirements, including measurement of a Single Breath Test MIP (maximal inspiratory pressure) and measurement of a Single Breath Test PIF/Flow Test (inspiratory muscle strength, peak inspiratory flow rate and inhaled volume). It also provides test results specifically for MIP (cmH2O) and PIF (litres). 

The KH1 has been developed for the following:

  • Doctors 
  • General Practitioners 
  • Respiratory and cardiac specialists
  • Surgeons 
  • Physiotherapists 
  • Nurses 
  • Patients with respiratory problems 

The K5 doesn’t include testing for MIP or PIF, nor therefore provide results. The K5 was developed for anyone who wished to improve their breathing strength and stamina for whatever reason, including individuals and sports people.

What’s the difference between the K4 and K5?

The K5 has additional features: the Pro Analysis View and the Custom Mode.

The Pro Analysis View enables you to see line graphs of each breath opposed to bar charts. This is good feedback to enable you to aim for a long flat line on the graph although some people prefer the bars.

The Custom Mode allows you to set a custom number of breaths at a selected load as opposed to the standard 30 breaths. For example you can select maybe 10 breaths on a heavy load or 60 breaths on a light load. This session can be done using the computer or uploaded to the unit. If you go for the K4 you could still do 10 of the 30 breaths and manually select a higher load if you specifically wanted to do this session.

Custom routine performed on the POWERbreathe unit; what will the load session show?

The POWERbreathe unit will only show the highest load set in the custom routine. It is advised to use the Breathe-Link software to get a more accurate view of pressure load. The values shown on the Breathe-Link software is the average pressure (average weight lifted) for the entire session. It is possible to analysis the data in greater detail in the Review Screen see Chapter 10 Data Review for more information.

In Auto training mode what does the levels settings mean?

The POWERbreathe K-Series unit will automatically estimate your training load at the beginning of every training session. Using this method, the device will adjust the training load every time you start a new session and as the strength of your inspiratory muscles increases. Automatic setup of this load takes place during the first two breaths of each training session. The intensity levels represent a percentage of your estimated load that you will be training at.

On the K3, why does the graph only show 36 results when the session number shows higher than 36?

The session number counts the total number of sessions you have completed (up to 999). However, the K-Series device can only store a maximum of your last 36 training session results – this is limited by the memory on the device and the display area on the screen.
