blood pressure

The measurement of arterial hemoglobin oxygen saturation, pulse, and blood pressure was presented. A review of methods for measuring arterial hemoglobin oxygen saturation based on photoplethysmography was provided. The architecture of the hardware and software platform of a cyber-physical system for the primary processing and transmission of information signals, based on a microcontroller with hardware encryption and a Bluetooth module for transmitting encrypted data to a mobile device and a remote server, was considered.

This paper presents the partial results of human presence impact on indoor air quality in a monitored office room. Indoor air temperature, relative humidity and carbon dioxide concentration are recorded in the investigated room during the operation. Simultaneously, the heartbeat (pulse) and blood pressure of respondents are determined. During the measurements, the investigated room was occupied only by one person. These measurements were repeated several times. Respondents were of different sex, different weight and different age.
