Researchers claim that a 'smart mask' can detect asthma, COPD, and other medical conditions.

Researchers have developed a "smart mask" that can detect clues to your health by analyzing your breath.

The EBCare, a mask that analyzes breath chemicals to detect health issues, was developed by Wei Gao, a professor of medical engineering at Caltech in Pasadena.

According to a press release from Caltech, the mask is designed to detect medical conditions such as respiratory infections, COPD, asthma, and post-COVID infections.

EBCare analyzes biomarkers in the breath by cooling it and transporting it to sensors.

Gao, the lead researcher, highlighted the mask's capacity to provide "real-time monitoring of exhaled breath condensate (EBC)" in a non-invasive and wearable format in an email to Planet Chronicle Digital.

Gao stated that this technology has the potential to revolutionize respiratory health monitoring by offering valuable insights into conditions such as asthma, COPD, and other metabolic disorders, leading to more personalized healthcare.

He added that it could be used in pandemic management by monitoring respiratory infections on a broad scale.

Gao emphasized that the ultimate aim is for EBCare technology to extend beyond respiratory illnesses.

He stated that as research advances, the smart mask may be modified to identify a broader spectrum of biomarkers, encompassing those associated with metabolic, cardiovascular, and infectious diseases.

According to Caltech, a study of the EBCare mask's capabilities involved 31 healthy adults who wore the mask in real-life settings for 14 hours, with breaks of three minutes to eat.

Recently recovered COVID-19 patients, smokers, asthmatics, and those with COPD comprised the group of 10 participants.

The biomarker for asthma and COPD was accurately detected in participating patients, as well as signs of kidney disease.

EBCare also produced accurate readings of blood alcohol levels.

Real-time monitoring of alcohol levels provides a non-invasive and continuous alternative to breathalyzers or blood tests, according to Gao.

"We would need to see at least a few clinical studies demonstrating that the masks can diagnose better — or more rapidly or with more sensitivity — than the standard of care."

The study, funded by several organizations including the National Institutes of Health and the National Science Foundation, was published in Science on Aug. 29.

Gao stated that the smart mask's purpose is not to replace traditional medical diagnosis but to provide "early warning" through continuous health monitoring during daily activities and to "bridge the gap" between doctor's visits.

He stated that the objective is to detect minor physiological alterations before they escalate into more serious health issues, allowing individuals to take preventive measures in managing their health.

Patients with chronic conditions or those recovering from respiratory infections like COVID-19 require regular monitoring, according to Gao.

He suggested that healthcare providers should integrate real-time EBC analysis technology into their diagnostic and monitoring practices, particularly for chronic conditions such as asthma and COPD.

"Wearable devices allow individuals to monitor their health non-invasively, enabling them to be proactive in managing personal health, which can result in early intervention and improved health outcomes."

MarkAlain Déry, DO, MPH, an infectious disease doctor and chief innovation officer at Access Health Louisiana, expressed excitement about the smart mask concept, despite not being involved in its development.

"Could it work? Sure," he told Planet Chronicle Digital.

He stated that we need to see clinical studies showing that masks can diagnose better than the standard of care, either more rapidly or with greater sensitivity.

"Then, we would need studies that demonstrate clinical improvement."

Potential limitations

Some external doctors not involved in the mask's development questioned the effectiveness of this data collection method.

In a conversation with Planet Chronicle Digital, Dr. Brett Osborn, a Florida neurosurgeon, raised an important question: "While the mask introduces an innovative method to monitor exhaled breath condensate (EBC), do these continuous, real-time measurements genuinely make a difference in everyday life?"

"Routine blood tests can provide more accurate and relevant information about biomarkers such as ammonium, pH, nitrite, and alcohol for the average person, making constant monitoring unnecessary."

According to Osborn, the EBCare mask is more suitable for "specific, high-stakes environments," such as monitoring toxic gases in military or industrial settings.

He stated that wearing a mask like this is counterproductive for the average person, particularly in the post-pandemic world.

Dr. John W. Ayers, PhD, questioned the idea of having patients with asthma or COPD wear masks, as they already experience breathing difficulties.

"For the average person, especially in a post-pandemic world, the idea of wearing a mask like this is counterproductive."

The lead researcher, Gao, responded to some of these comments.

Routine blood tests are reliable but limited in their ability to capture dynamic, day-to-day physiological changes due to their periodic nature and requirement for a clinical setting, according to the expert.

"The EBCare mask's real innovation is its continuous real-time health monitoring, providing insights that may not be detectable with intermittent tests."

Research suggests that fluctuations in biomarkers can serve as early warning signs for individuals with chronic conditions like asthma, COPD, or metabolic disorders, enabling timely intervention before symptoms worsen.

Gao, however, did acknowledge some limitations with the EBCare device.

He informed Planet Chronicle Digital that one limitation in some clinical trials for conditions like COPD and asthma was the small sample size.

"Studies with larger and more diverse populations will aid in validating the device's performance in a wider range of conditions and environments."
