Static pulmonary compliance in ponies

Journal of Applied Physiology, 1975
Static pulmonary and total compliance during expiration was measured in fifteen healthy anesthetized ponies. Mean body weight of the ponies was 140.6 kg and ranged from 83.6 to 211.4 kg. For the fifteen ponies, mean values and SD were: total compliance (Ct), 168.7 plus or minus 47.2 ml/CMH2O, and mean pulmonary compliance (Cl), 368.4 plus or minus 90 ...

Pulmonary Compliance

American Journal of Diseases of Children, 1972
Pulmonary compliance in infants was calculated by (1) determining tidal volume with a whole body plethysmograph and (2) substituting intraesophageal pressure for intrathoracic pressure. Compliance is expressed as the ratio of tidal volume to change in pressure measured at extremes of tidal volume.

Pulmonary Compliance and Mechanical Ventilation

Archives of Surgery, 1992
Normal, spontaneous breathing begins with contraction of the muscles of inspiration, which effect expansion of the thoracic cage and create a pressure in the pleural space that is negative with respect to that of the atmosphere. Since the airway pressure in the lung at end-expiration is in equilibrium with the atmosphere, the transthoracic negative ...

Pulmonary Compliance: Alteration during Infection

Science, 1971
Lungs excised from rats infected with Mycoplasma pulmonis are more difficult to inflate with air than those from uninfected animals; they show no significant differences from controls inflated with saline. The altered pulmonary function in lungs from infected rats is attributed to an increase in surface forces ...

Pulmonary vascular compliance and viscoelasticity

Journal of Applied Physiology, 1986
When dog lung lobes were perfused at constant arterial inflow rate, occlusion of the venous outflow (VO) produced a rapid jump in venous pressure (Pv) followed by a slower rise in both arterial pressure (Pa) and Pv. During the slow rise Pa(t) and Pv(t) tended to converge and become concave upward as the volume of blood in the lungs increased.

Time-varying pulmonary arterial compliance

Journal of Applied Physiology, 1991
We tested the hypothesis that pulmonary arterial compliance (Ca) varies during the ventilatory cycle. Pressure and flow in the main pulmonary artery were measured in open-chest dogs under chloralose anesthesia (n = 12) with a positive-pressure volume-cycled ventilator.

REDUCED PULMONARY ARTERIAL COMPLIANCE IN HYPERTENSIVE PREGNANCY

The Lancet, 1973
Abstract Lung-capillary blood-flow has been compared in normal pregnant women and women with hypertension in pregnancy using nitrous-oxide whole-body plethysmography. Pulmonary-artery distensibility was assessed by measuring pulmonary-artery/capillary-flow conduction-times (C t ).

Compliance with pulmonary medication in general practice

European Respiratory Journal, 1993
We wanted to assess compliance with regular pulmonary medication, in 156 patients in a general practice setting. Patients completed a questionnaire on their reported daily intake, the perceived prescription, and their self-assessed perceived compliance with pulmonary medication.

PULMONARY COMPLIANCE CHANGES AFTER EXPERIMENTAL HEAD INJURY

The Journal of Trauma: Injury, Infection, and Critical Care, 1976
Reduced static compliance has been reported in the lungs of experimental animals removed immediately after head injury. To relate these findings to clinical human experience, pulmonary dynamic compliance measurements were continuously made by clinically applicable methods in 18 monkeys subjected to severe head trauma.
