The development of blood pressure earcons for patient monitoring is used to illustrate how data that varies from intermittent to continuous sampling can be integrated into a single auditory display design. A scalable-earcon structure that extends the concept of hierarchies of earcons is proposed for representing blood pressure information. This structure allows the earcon to be used to produce ...

The bronchodilator and cardiac effects produced by aerosols of 0.5% isoprenaline and of 0.25, 0.5, and 1% salbutamol administered in 40% oxygen by intermittent positive-pressure ventilation were compared in 24 asthmatic patients. Isoprenaline and salbutamol in concentrations of 0.5% were equipotent in peak bronchodilator effect; salbutamol was superior in total bronchodilator effect and duratio...

OBJECTIVE Negative pressure wound therapy (NPWT) can be delivered in continuous or noncontinuous modes, while NPWT with instillation (NPWTi) couples NPWT with automated delivery and removal of topical wound treatment solutions and suspensions. This porcine study compared granulation response of NPWTi (instillation foam dressing with saline) to NPWT (standard foam dressing) in continuous and non...

The effects of intermittent and continuous positive pressure were studied in mechanically ventilated healthy dogs. No statistically significant changes were produced in oxygen tension, carbon dioxide tension, alveolar-arterial gradients or shunts by continuous positive pressure. It did produce a significant reduction in cardiac output and total oxygen delivery which was reversed by the reintrod...

Minute amounts of Locke's or Tyrode's solution have been brought into contact with the interstitial connective tissue of the skin of the living mouse, at atmospheric pressure, in such a manner that the blood or lymphatic vessels are not entered directly. Under such circumstances these absorbable fluids enter the tissue spontaneously. Entrance is strikingly intermittent, not continuous, and so t...

For the past three years the Pediatric Research Department of the Lovelace Foundation has been engaged in investigative and clinical studies of the use of intermittent positive pressure breathing (hereinafter termed IPPB) therapy in the field of pediatrics. Studies in infant resuscitation1 have proved its worth in (1) expanding the non-expanded lungs of newborns who do not breathe at birth, (2)...

IPPB 2.0 DESCRIPTION/DEFINITION: The first American Association for Respiratory Care (AARC) clinical practice guideline (CPG) for Intermittent Positive Pressure Breathing (IPPB) was published in 1993. Since that time there have been additional studies, systematic overviews, and a meta-analysis that specifically addresses the eff icacy of IPPB as compared to other hyperinflation and aerosol deli...
