Airway clearance: physiology, pharmacology, techniques, and practice.
Clinicians and their patients are troubled by respiratory secretions, and standard practice calls for efforts to clear secretions from the lungs. On one hand, mucus production and cough are important for airway defense and protection of the lower respiratory tract against inhaled irritations. On the other hand, excessive mucus obstructs airways and excessive cough has been associated with a num...

متن کاملSecond messengers, ion channels and pharmacology of airway smooth muscle.
The airway smooth muscle cell is the chief effector cell governing the control of airway calibre in the human lung. The contractile state of the airway smooth muscle cell is predominantly influenced by the balance of constrictor and relaxant stimuli. Agents such as histamine and acetylcholine cause airway smooth muscle cells to contract through activation of specific cell surface receptors and ...
متن کاملStudying human airway pharmacology in microsections: application of videomicrometry.
The influence of endogenously-released mediators and activated eosinophils on the airway lumen and the effect of passive sensitization on anti-immunoglobulin (Ig)-E-induced contractile responses was investigated by videomicrometry. Human bronchial sections of 2-3 mm internal diameter, placed in 250 microL Hank's balanced salt solution on microtitre plates, were monitored and recorded by digitiz...

Daniel I. Sessler, MD† BACKGROUND: In previous studies, we showed that failure to respond to automated responsiveness monitor (ARM) precedes potentially serious sedationrelated adversities associated with loss of responsiveness, and that the ARM was not susceptible to false-positive responses. It remains unknown, however, whether loss and return of response to the ARM occur at similar sedation ...
