Abstract Background Deep inspirations DI have bronchodilatory and bronchoprotective effects in healthy human subjects but these effects appear to be absent in asthmatic lungs. We have characterized the effects of DI on lung mechanics during mechanical ventilation in healthy mice and in a murine model of acute and chronic airway inflammation. Methods Balb c mice were sensitized to ovalbumin OVA and exposed to nebulized OVA for l week or l2 weeks. Control mice were challenged with PBS. Mice were randomly selected to receive DI which were given twice during the minute before assessment of lung mechanics. Results DI protected against bronchoconstriction of central airways in healthy mice and
