Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The study will be conducted in hospitalised patients who undergo spot-check monitoring of vital signs as part of their routine care.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

In an additional spot-check measurement procedure, the study will measure oxygen saturations through different Philips SpO2 finger sensors. Patients will wear a nasal cannula linked to a CO2 measuring device at the same time. The data from both devices will be used to design and improve algorithms for measurement of respiratory rate with the saturation probe and the Philips FAST pulse oximeter system. The study will include 50 adult patients and 25 pediatric patients.
