Capnography, the measurement of carbon dioxide (CO2) levels in exhaled air, has emerged as a valuable tool in managing respiratory conditions such as Chronic Obstructive Pulmonary Disease (COPD ...

In asthma, worse acute exacerbation outcomes may be predicted by lower end-tidal carbon dioxide (EtCO 2), although other capnography waveform measures may be more useful severity indicators ...

Obstructive sleep apnea is caused by the collapse of the upper airway during sleep. The muscles supporting soft tissues in the throat relax, narrowing or closing the airway and temporarily ...

COPD stands for chronic obstructive pulmonary disease. It is a general term that includes various ... An arterial blood gas (ABG) test measures the levels of oxygen and carbon dioxide in blood from an ...

You must go to a doctor to know for sure whether you have COPD. That’s because there are things to consider for a diagnosis. Some people have asthma and COPD at the same time. If you have ...

Chronic obstructive pulmonary disease (COPD) is a disease of the respiratory tract that is characterized narrowing of the small airways and destruction of lung tissue. This leads to poor airflow ...

The level of carbon dioxide in the atmosphere measured by a weather station at the Mauna Loa Observatory in Hawaii increased by 3.58 parts per million in 2024 – the biggest jump since records ...

Abstract: We propose and experimentally demonstrate a novel approach to the photonic generation of high-sampling-rate arbitrary microwave waveforms in a temporal synthetic dimension created by two ...

To address this issue, we propose an stepped-frequency PMCW (SF-PMCW) radar waveform in which the instantaneous bandwidth of a single pulse is extensively reduced while the range resolution is beyond ...

Left ventricular assist devices (LVADs) are increasingly common across the heart failure population. Right ventricular failure (RVF) is a feared complication that can occur in the early post-operative ...

Carbon dioxide is a colorless, odorless gas that is retained in the blood when sleep disorders occur. Its chemical compound consists of one atom of carbon covalently bonded to two atoms of oxygen.
