The Evolution of CPAP Machines in Treating Snoring and Sleep Disorders
Sleep medicine physician Dr. Linda Schachter emphasizes that if snoring disrupts a partner's sleep, it is worth seeking treatment. This perspective highlights a growing shift in how medical professionals address snoring, moving beyond mere annoyance to recognize its potential health implications.
From Camping Jokes to Medical Diagnosis: A Personal Journey
Nick, who requested his first name only be used, recalls setting up his tent 100 meters away from friends during camping trips due to his loud snoring. He used humor to cope with this social issue from his teenage years. However, in 2019, at age 37, a doctor's visit revealed alarming high blood pressure despite his active lifestyle and healthy diet. This prompted him to connect the dots with other symptoms, including uncontrollable daytime tiredness that led to micro-sleeps in meetings and on public transport.
During a sleep test, Nick noticed a CPAP machine—standing for continuous positive airway pressure—next to the bed. Initially, the attendant explained it was for observational purposes only, but within an hour, the lights came on, and the mask was activated. The attendant noted that from 30 paces away, they didn't need microphones to assess the severity of Nick's condition. He was diagnosed with severe obstructive sleep apnoea, a disorder where throat muscles relax too much during sleep, causing breathing to stop or become shallow.
The Continuum from Snoring to Sleep Apnoea
Dr. Linda Schachter explains that snoring represents partial upper airway obstruction, and as this obstruction worsens, it can develop into sleep apnoea. Historically, humans have sought practical solutions for snoring, such as ancient Egyptian recommendations of thyme or sewing cannonballs into soldiers' uniforms during the US War of Independence to prevent back-sleeping. However, medical interest in snoring is relatively new, according to Professor Peter Cistulli of the University of Sydney.
Early in Cistulli's career, sleep apnoea was considered rare, with tracheostomy as the only treatment. Today, less-invasive options like CPAP machines have emerged, alongside improved sleep measurement technologies and growing awareness. Cistulli notes a rapid spike in sleep medicine popularity over the past 30 years, partly driven by wearable consumer tech that monitors sleep. The CPAP was invented by his mentor, Professor Colin Sullivan, and first sold commercially by ResMed, an Australian company whose value has more than quadrupled in the last decade.
Revelatory Experiences and Celebrity Endorsements
When Nick used a CPAP mask for the first time during his sleep test, he slept for four uninterrupted hours. He describes the experience as revelatory, with unprecedented energy, clarity, and well-being upon waking. Initially, CPAPs were reserved for severe sleep apnoea cases, but Schachter reports a rise in prescribing for milder conditions as doctors recognize symptoms more readily.
The devices have gained celebrity endorsements, with figures like Amy Poehler and Jack Black praising them for improving snoring. On platforms like Reddit, users even credit CPAPs with saving marriages. However, Dr. Donald Lee of the Woolcock Institute of Medical Research warns that some third-party retailers market CPAP machines as consumer technology, which can be misleading.
Risks, Misconceptions, and Treatment Options
Cistulli mentions a new term, orthosomnia, where people become overly preoccupied with achieving perfect sleep due to wearables. While CPAP therapy is safe when properly set up, Schachter cautions that incorrect pressure settings can cause issues like air swallowing or sleep disturbance. Lee likens CPAPs to a vacuum cleaner turned the other way, noting they can be uncomfortable and claustrophobic, so motivation to use them depends on tangible benefits.
Cistulli observes that the stereotypical sleep apnoea patient—an overweight, middle-aged man who drinks alcohol—is evolving, with more subtle forms appearing at younger ages and across genders. Schachter adds that women have been under-treated for sleep apnoea, often presenting with significant tiredness despite mild diagnoses. There's also recognition of upper airways resistance syndrome, where breathing causes sleep disturbance without full apnoea criteria.
Cistulli stresses that snoring is not benign and warrants medical investigation to prevent progression to sleep apnoea. Schachter notes that snoring itself can pose health risks, such as associations with stroke in some trials, though Lee calls for more data. Beyond health, snoring affects relationships, making treatment worthwhile if it disturbs a partner.
If a sleep test shows no apnoea, Schachter says it's unusual to use a CPAP unless symptoms are severe or upper airways resistance syndrome is present. She highlights alternative treatments, including mouth splints, nasal dilators, and weight-loss drugs, which are often first-line for mild to moderate cases. Lee advises consulting a doctor for any health concerns.
Nick compares his CPAP use to getting glasses after gradual eyesight erosion, stating it's no big deal after years of management. He concludes, In a world of trade-offs, it's absolutely no contest. Self-care is sexy.
