Safety Guidelines
Effective date: 06-05-2026
RedPlus uses controlled breath-hold hypoxia and SpO₂ tracking. This means that oxygen saturation may temporarily drop during or after a breath-hold session.
You must read and follow these Safety Guidelines before using RedPlus, performing any RedPlus session, or accepting the Safety Clearance inside the app.
By using RedPlus, you confirm that you understand the risks, accept responsibility for safe use, and agree to follow all app warnings, safety pop-ups, vibration alerts, and instructions.
1. RedPlus Is Not Medical Advice
RedPlus is a performance and training tool. It is not a medical device, diagnostic tool, treatment, or substitute for professional medical advice
RedPlus does not diagnose, prevent, treat, or cure any medical condition
If you have any medical concerns, you must consult a physician or qualified healthcare professional before using RedPlus.
2. Do Not Use RedPlus If You Have Health Risk
You must not use RedPlus without prior medical clearance if you have, or suspect you may have, any of the following
heart disease or known heart defects
history of heart attack, stroke, arrhythmia, fainting, seizures, or loss of consciousness
high blood pressure, especially if uncontrolled
respiratory disease, asthma, COPD, sleep apnea, or reduced lung function
neurological conditions
pregnancy
anemia, iron deficiency, blood disorders, or abnormal hematocrit/hemoglobin values
recent surgery, acute illness, fever, infection, or unexplained fatigue
any condition where reduced oxygen saturation may create increased risk
Breath-hold activities can create hypoxia, and official safety warnings around breath-holding note that hypoxia can lead to unconsciousness in dangerous contexts, especially in water or unsafe environments.
3. Use Only in a Safe Position
RedPlus sessions must only be performed:
seated
lying down
in a safe indoor or controlled environment
away from water, traffic, stairs, machinery, sharp objects, or any situation where dizziness or loss of control could cause injury
You must never use RedPlus:
while driving
while cycling
while swimming
in water
while standing in an unsafe place
while operating machinery
during sport or physical movement
alone if you are inexperienced or uncertain about your response
4. Do Not Compete With the App
RedPlus is not a competition to hold your breath as long as possible or force SpO₂ as low as possible.
The purpose is controlled hypoxic dosing.
You must not chase extreme SpO₂ drops, ignore warning signals, or push beyond the app’s safety guidance.
The typical RedPlus working range is intended to be controlled and progressive. The preferred performance zone is generally around 70–80% SpO₂, but users must follow the app’s current guidance and safety alerts at all times.
Pulse oximeters are also less accurate at very low readings; UK medical-device guidance notes that accuracy falls below 70% SpO₂, so very low numbers should not be treated as precise measurements.
5. Follow All App Warnings
RedPlus may use safety warnings including:
pop-up warnings
vibration alerts
visual warning signals
stop-session instructions
SpO₂ threshold alerts
recovery guidance
session-limit guidance
You must follow these warnings immediately.
If the app tells you to stop, recover, or avoid continuing, you must stop the session.
Ignoring app warnings, pushing below recommended limits, or continuing despite symptoms is misuse of RedPlus and is done at your own risk.
6. Stop Immediately If You Feel Unwell
Stop the session immediately if you experience:
dizziness
faintness
chest pain
abnormal heart rhythm
confusion
visual disturbance
tingling or loss of control
unusual shortness of breath
panic
nausea
headache
prolonged low SpO₂
any feeling that something is wrong
If symptoms continue, seek medical assistance.
Normal resting SpO₂ is commonly around 95–99% in healthy individuals, though some people with lung or heart conditions may have different baseline values and should consult a doctor about what is normal for them.
7. Respect Baseline Recover
During a RedPlus repetition, SpO₂ may continue to fall after the breath-hold ends.
A repetition includes:
the breath-hold phase
the recovery period after the breath-hold
The SpO₂ dip often appears during recovery, which is why recovery time matters.
As a general principle, users should allow sufficient recovery between repetitions. More experienced users may start the next repetition when SpO₂ has returned toward baseline, but only if they feel normal and the app does not show any warning.
8. Do Not Hyperventilate
Do not deliberately hyperventilate before a RedPlus breath-hold.
Hyperventilation can reduce the normal urge to breathe and may increase the risk of hypoxic blackout, especially in unsafe environments or water-related contexts. Safety organisations warn that hyperventilation and extended breath-holding in water can be dangerous and potentially deadly.
9. Use Reliable Equipment
RedPlus depends on SpO₂ measurement.
You should use a compatible pulse oximeter and make sure it is fitted correctly.
Readings may be affected by:
cold fingers
movement
poor sensor placement
nail polish or artificial nails
poor circulation
device quality
very low SpO₂ levels
sensor delay
Use SpO₂ trends as guidance, not as a guaranteed precise medical measurement.
10. Weekly Target and Progression
RedPlus uses weekly app targets and progress visualisation to support structured use.
The target is a training reference inside the app. It is not a medical promise and does not guarantee any specific biological result.
Estimated RBC/HCT progress values are app-based estimates. They are not laboratory measurements.
You must progress gradually and avoid sudden increases in volume, intensity, or number of repetitions.
11. Beta and Development Status
If you are using a beta version of RedPlus, you understand that the app is still under development
Beta features, warnings, thresholds, calculations, displays, and recommendations may change
You must use extra caution during beta testing and report any unexpected issue, symptom, sensor error, or app behaviour to RedPlus.
12. Your Responsibility
By using RedPlus, you agree that:
you have read these Safety Guidelines
you understand that hypoxic training involves risk
you are responsible for using the app safely
you will follow all warnings and instructions
you will stop if you feel unwell
you will not use RedPlus in unsafe situations
you will seek medical advice if you have health concerns
you will not misuse the app to chase extreme SpO₂ drops
Failure to follow these Safety Guidelines may increase the risk of injury, fainting, loss of consciousness, or other adverse events.
13. Emergency Warning
Seek urgent medical help if you experience:
chest pain
fainting
loss of consciousness
severe shortness of breath
confusion
blue lips or face
persistent abnormal oxygen saturation
symptoms that do not quickly resolve after stopping
