Opioid Safety

Masimo SafetyNet Alert™ Calls for Help When You Can't

Gain Peace of Mind with Reliable Continuous Monitoring


Will you be able to call for help?

Prescription opioids can be a powerful way to help manage pain. But they can also carry serious effects, including slowed or stopped breathing. You may be at risk and not even know it.

If slowed or stopped breathing happens while you sleep, there’s a chance you might never wake up.

Accidental overdose can happen to anyone

30% of surveyed patients who are prescribed opioids don’t know they’re taking them.1

Opioids go by many names, and the word “opioid” doesn’t always appear on the label. It’s possible that you or a loved one could be taking them without even knowing.

Each of these medications is categorised as an opioid

Did You Know?


Anyone taking opioid painkillers is vulnerable to respiratory side effects. What's more, the risk increases if:2-5

  • You are taking opioids for the first time
  • You have a respiratory condition such as sleep apnea, COPD, asthma, or some chronic conditions
  • You combine opioids with alcohol or other sedating medications, such as sleeping pills or anti-anxiety medicine
  • You take high opioid doses (>50 MME)
  • You have a history of addiction

~50% of opioid-related deaths happen when a person is alone.6 Without immediate help, permanent brain damage or death can occur within minutes.7

At-home monitoring can help.

You shouldn’t fear filling your prescription, but you should know how you can protect yourself from the potential dangers of opioids.

Masimo SafetyNet Alert™ continuously monitors your blood oxygen level–providing alerts to help wake you, and notify your loved ones, if your oxygen level drops too low.

It's important to remember...

Slowed or stopped breathing can happen to anyone taking prescription opioids.8

Because of your unique physiology, the severity of your experience can be unpredictable.

It can happen in the hospital, or at home, and is most dangerous when you are alone or asleep.

Know your oxygen levels.

Worried about your oxygen levels?

Oxygen levels can change quickly. Will you know when help is needed?

Now there's a way to help protect yourself at home.

Sleep Apnea

Oxygen levels can drop while sleeping. Relaxed throat muscles can block airways, potentially causing breathing to stop anywhere from seconds to over a minute.9

Chronic Obstructive Pulmonary Disease (COPD)

With COPD, airways in the lungs become inflamed, leading to decreased air flow, less oxygen in bodily tissue, and difficulty exhaling carbon dioxide.10


Due to damage and irritation to the respiratory system, asthma can lead to decreased blood oxygen levels. Severe flare-ups can also lead to low oxygen in body tissues (hypoxia).11

Respiratory Syncytial Virus (RSV)

RSV is a respiratory virus that causes cold-like symptoms and can be serious for infants or older adults, potentially leading to bronchiolitis or pneumonia.12

"I had no idea. You can die when you’re taking these." —Yvonne Gardner

Parker Stewart, Yvonne’s son, was a healthy 21-year-old who underwent a routine tonsillectomy, and stopped breathing after taking only half his prescribed dose of opioid painkillers. He died in his sleep while his wife slept beside him.
