Abstract:
From March 2, 2020, to April 26, 2020, 52,588 reverse transcription polymerase chain reaction (RT-PCR) tests for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) were performed in France, 6490 in children and 46,098 in adults. The rate of RT-PCR-positive SARS-CoV-2 tests for children (5.9%) was always less than that for adults (20.3%) but vary according to the epidemic stage. The risk ratio of RT-PCR-positive SARS-CoV-2 tests for adults compared with children was 3.5 (95% confidence interval: 3.2-3.9) for the whole study period.

Assessment of Ventilation I: Respiratory Rate
A Ventilation assessment is critical for monitoring a patient's health status. Respiration, one of the most accessible vital signs, provides insights into the function of numerous body systems and can indicate serious health issues, such as brainstem injuries from head trauma.
Critical Guidelines for Assessing Ventilation:
