Passive acoustic thermometry (PAT) was used to study the dynamics of changes in the chest temperature of a person with COVID-19 over the course of about two and a half weeks after quarantine. PAT, which can measure deep body temperature, showed that the integral temperature of tissues surrounding the lungs increased from 32.2 ± 0.

Nonetheless, we present a case of IO insertion to a 56-year-old man, tetraplegic for many years due to progressive spinal muscular atrophy and with refractory suffering. The IO access was used for palliative sedation with propofol in a home care setting.

Because in the PAT a noise signal is measured, a considerable integration time (about one minute) is required to attain an acceptable error level (0.5-1K).

For passive detection of the thermal ultrasonic radiation an acoustic radiometer was developed, based on a broadband 0.8-3.

This method is based on the measurements of the own thermal acoustic radiation of the investigated object. These two patients have got the brain injury.
