Arising from the Antoine equation and the ideal gas law, the volume of exhaled water has been calculated. Air temperature, humidity and minute ventilation has been taken into account. During physical exercise amount of exhaled H(2)O is linear, but not proportional to heart rate. And so at the heart rate of 140 bpm amount of exhaled water is approximately four times higher than during the rest and equals about 60-70 ml/h. The effect of external temperature and humidity on water lost via lungs… 

A new and simple parameter for diagnosis pulmonary edema: Expiratory air humidity.

COVID-19 symptoms are reduced by targeted hydration of the nose, larynx and trachea

Hydration of the upper airways appears promising as a non-drug approach for reducing risks of respiratory diseases such as COVID-19.

COVID-19 symptoms reduce with targeted hydration of the nose, larynx and trachea

Hydration of the upper airways appears promising as a non-drug approach for reducing risks of lower respiratory-tract infections such as COVID-19.

Age-Related Changes in the Thermoregulatory Properties in Bank Voles From a Selection Experiment

The selection for high aerobic exercise metabolism attenuated the adverse effects of aging on cold tolerance, but this advantage has been traded off by a compromised coping with hot conditions by aged voles.

Humidity Distribution in High-Occupancy Indoor Micro-Climates

The general consensus among academics is that the spatio-temporal humidity distribution is more or less uniform in an indoor space. This has, for the large part, not yet been proven by an academic

Requirements for Supporting Diagnostic Equipment of Respiration Process in Humans

New equipment for assessing the parameters of human respiration, which can be easily adopted for daily diagnosis is presented and the issue of developing the correct method of obtaining measurement data is dealt with.

Ability of fabric face mask materials to filter ultrafine particles at coughing velocity

The findings suggest that face masks made from layered common fabric can help filter ultrafine particles and provide some protection for the wearer when commercial face masks are unavailable.

Textile Masks and Surface Covers—A Spray Simulation Method and a “Universal Droplet Reduction Model” Against Respiratory Pandemics

House textiles were assessed to quantify their potential as effective environmental droplet barriers (EDBs) and the synchronized implementation of a universal “community droplet reduction solution” is discussed as a model against COVID-19.
