The respiratory center is divided into three major groups, two in the medulla and one in the pons. The two groups in the medulla are the dorsal respiratory group and the ventral respiratory group. In the pons, the pontine respiratory group is made up of two areas – the pneumotaxic center and the apneustic center. The dorsal and ventral ...
Complete respiratory system. The respiratory tract is divided into the upper airways and lower airways.The upper airways or upper respiratory tract includes the nose and nasal passages, paranasal sinuses, the pharynx, and the portion of the larynx above the vocal folds (cords).
In a train of multiple pulses it is usually varying due to the difference between phase and group velocity. The time, after which the phase increases resp. decreases by 2 π {\displaystyle 2\pi } is called T C E O {\displaystyle T_{\mathrm {CEO} }} .
Respiratory tract infections (RTIs) are infectious diseases involving the lower or upper respiratory tract. [1] An infection of this type usually is further classified as an upper respiratory tract infection (URI or URTI) or a lower respiratory tract infection (LRI or LRTI).
To assess areas of tenderness, palpate areas of pain, bruises, or lesions on the front and back of the chest.

Abnormal masses or sinus tracts may point to ...

Respiratory sounds, also known as lung sounds or breath sounds, are the specific sounds generated by the movement of air through the respiratory system. [1] These may be easily audible or identified through auscultation of the respiratory system through the lung fields with a stethoscope as well as from the spectral characteristics of lung sounds.

This limits the dead space to between the non return valves and the user's mouth or nose. Not all of the volume between the non-return valves is necessarily dead space, as exhaled gas in narrow ducting will not necessarily mix well with fresh gas from inhalation ducting, but exhaled gas beyond the exhaust non-return valves can reasonably be ...
