ResMed’s history in sleep medicine

In 1981, Professor Colin Sullivan and colleagues at the University of Sydney developed the first continuous positive airway pressure (CPAP) device, the first successful, non-invasive treatment for obstructive sleep apnoea.

In 1989, ResMed was founded to commercialise this device. Over the past 27 years, awareness about the dangers of sleep disordered breathing (SDB) and untreated obstructive sleep apnoea (OSA) has increased, and ResMed has introduced lighter, quieter and more comfortable equipment to help those with sleep apnoea (and their bed partners) sleep and live better.

We now help patients in more than 100 countries through ResMed offices and a vast network of equipment suppliers.

Since 1989, we have maintained our focus on SDB, while also expanding into the fields of respiratory medicine and cardiology. We help make quality care accessible for those with diseases such as chronic obstructive pulmonary disease (COPD) and motor neuron disease.

We have long recognised that a large proportion of the world’s population  has problems sleeping at night and that, as specialists in sleep, we could use our deep knowledge to help not only track your sleep but also analyse and improve it. We’ve spent more than 10 years developing the S+ – analysing more than 2 million nights of sleep to develop the very best solution available.

Most important, we wanted to develop a solution that was easy to use and accurate. So we tested S+ rigorously in 10 published clinical studies.

Information on sleep by Dr. Guy Meadows

* ResMed recorded and analysed 2,000,000 nights of sleep in the development of S+

** Users with average sleep scores between 50-60 improved their sleep by an average of 44.71 minutes per night after one week of use.

*** Below average users are those with an average sleep score below 75. Poor sleep is defined as an average sleep score between 50-60. Very poor sleep is defined as an average sleep score between 30-50. Users with average sleep scores between 30-50 improved their sleep by more than 70 minutes per night after one week of use. Aggregate S+ user data as of 03/19/2015. All data is derived from a sample size of [5932] users as of 03/19/2015. Your results may be different.

Note: S+ is not a medical device. If you are seeking information on how to treat a sleep disorder, you should talk to your healthcare provider.
