Frequently Asked Questions

How accurate is Donisi’s technology?

When compared against gold standard systems, Donisi’s robust sensing technology maintains medical-grade accuracy in a wide variety of conditions. Our technology is backed by clinical testing of over 1300 participants of different ages, genders, ethnicities, and health statuses.

How does contact-free sensing work?

The sensor uses an invisible (infrared) light source that illuminates a surface, such as a person’s chest (through clothing). Using our unique and patented algorithm, nanometric vibrations on the illuminated surface are then translated into physiological parameter detection. Further analytics are applied to provide personalized trends and insights.

How does Donisi’s contact-free monitoring solution compare to a smart watch or wearable?

Donisi’s solution enables the detection of a wide array of physiological indicators with medical grade accuracy in order to assess cardiac and pulmonary function, stress, and overall well-being.

What is the distance range of the device?

The device was designed to maintain full medical-grade accuracy in a variety of conditions and environments. Depending on the model, Donisi’s technology maintains accuracy up to 5 meters (16 feet) so long as there is a line of sight between the user and sensor.

Are Donisi’s devices approved by the FDA?

Donisi’s product is currently undergoing the FDA certification process as a de novo technology for heart and respiratory rates. We expect to have approval Q1-2021. Additional submissions are expected/under development.

Does the sensor work with clothing?

Yes! The device was designed to maintain full medical-grade accuracy in a variety of conditions and environments, including with multiple layers of clothing.

Is contact-free sensing safe?

Absolutely! Donisi’s health monitoring solutions are completely non-invasive and contact-free. All system components (including optical components) are fully compliant with international safety standards.

What is Heart Rate?

Heart rate is the number of times the heart beats per minute. Normal heart rate varies from person to person but typically lies between 60-100 beats per minute. Changes in heart rate and rhythm may signify a developing heart condition or other condition that needs to be addressed.

What is Respiratory Rate?

Respiratory rate is the number of breaths a person takes per minute. The rate is usually measured when a person is at rest. Normal respiratory rate for adults at rest range from 12 to 20 breaths per minute. Respiratory rate may increase with fever, illness, and other medical conditions.

What is Heart Rate Variability?

Heart rate variability (HRV) is a measure of the variation of time between heartbeats. Consistent monitoring of HRV can help track change in physiological stress levels, which may be affected by underlying conditions, such as respiratory or cardiac conditions. Low HRV has been shown to be independently predicative of increased mortality in heart failure and post-heart attack patients.

What is Stress?

Stress is a phenomenon we’ve all experienced. Although a little bit of stress can be helpful at times, prolonged mental stress can have major impacts on overall health, well-being, worker proficiency, recovery time from physical activity, and more. Stress can manifest itself through multiple physiological parameters, such as prolonged rapid heart rate and respiratory rate, and low HRV.

What is ECG?

The electrocardiogram (ECG) is used to assess heart rate and rhythm. It measures the electrical activity of the heart and can be used to identify irregular heart rhythms (arrhythmias) which may be associated with different heart conditions such as atrial fibrillation or heart failure.

What is Atrial Fibrillation (AFib) Detection?

Atrial fibrillation (AFib) is a form of irregular heart rhythm (arrhythmia) that is characterized by rapid and irregular beating of the heart. It often begins with short periods of abnormal beating which worsen over time. In addition to its own set of health status complications, it is also a critical component in assessing health status for patients with a heart condition.

What is Ejection Fraction?

Ejection fraction (EF) is a measurement of the percent of blood the heart pumps to the body with each heartbeat relative to how much blood there was in the heart pre-beat.  Factors such as heart rate, blood pressure, chest pressure and the strength of the heart muscle itself can impact the heart’s “pump efficiency”.  An ejection fraction of 55% or higher is considered normal. Low ejection fraction may be indicative of cardiac dysfunction.

What is Pulmonary Congestion?

Pulmonary congestion occurs when there is an accumulation of fluid in the lungs. This buildup of fluid in the lungs, instead of air, results in impaired gas exchange. In early stages it makes breathing less efficient, causing shortness of breath. In advanced stages, breathing can become exceedingly difficult. The severity of congestion often coincides with changes in disease conditions such as heart failure or COPD.

What is Respiratory Rhythm?

Normal breathing is a seemingly effortless, relatively consistent pattern of inspiratory and expiratory frequency and amplitude (rate + volume). However, unexpected changes in breathing effort, frequency, volume, etc., can indicate more severe cardiac and pulmonary conditions.
