Summary The purpose of the study was to document the developmental changes in the ventilatory and timing parameters associated with quiet breathing at rest in awake, standing horses during the first year post partum. Tidal volume (VT), breathing freq

This study investigated the developmental changes in the mechanical properties of the respiratory system in growing horses. Pulmonary mechanics and lung volumes were serially measured in anesthetized foals during the first year of life. Quasi-static

The nature and control of early neonatal respiratory patterns were determined in 10 premature, asphyxiated lambs. Severe retardation of early expiratory airflow (braking) characterized an initial pattern (A), but was absent in a final one (B). During

We evaluated eight infants with bronchopulmonary dysplasia (BPD) at ages from 2 to 13 months who had repeated episodes of clinical respiratory deterioration associated with agitation. These episodes limited further weaning from ventilation or necessi

Laryngeal and pump muscle activities are important in the establishment and maintenance of functional residual capacity (FRC) after birth. The aim of this study was to determine the expiratory mechanisms by which laryngeal and diaphragmatic activitie

Term human newborns were challenged with a 2–3% CO2 gas mixture during quiet sleep. A common ventilatory response, consisting of increased tidal volume with no change in respiratory frequency or timing, was observed in all eight subjects. Minute ve

In animals and human adults, upper airway muscle activity usually precedes inspiratory diaphragm activity. We examined the interaction of the posterior cricoarytenoid muscle (PCA), which abducts the larynx, and the diaphragm (DIA) in the control of a

The discharge of 57 slowly adapting pulmonary stretch receptors (PSR's) and 16 rapidly adapting receptors (RAR's) was recorded from thin vagal filaments in anesthetized dogs. The receptors were localized and separated into three groups: extrathoracic

The ferret, Mustela putorius furo, is a small relatively inexpensive carnivore with minimal housing requirements. Measurements were made from anesthetized tracheotomized supine males. Values obtained during tidal breathing for six animals (576 +/- 12

Control of upper airway muscles, such as those in the larynx, appears important for optimizing airflow patterns during normal respiration. Electromyograms (EMGs) of the laryngeal (LAR) area and diaphragm (DIA) were recorded with esophageal and skin e
