Aims: Feasibility of measuring interrupter resistance (Rint) in acute asthmatics presenting to the paediatric emergency department and assess its value in assisting clinical decision making.
Methods: Clinical parameters were recorded and Rint measurements attempted (Superspiro, Micromedical UK) prior to and 30 minutes after first nebulised bronchodilator (BD).10 interruptions were performed at both time points. Pressure waveforms were visualised and technically unsatisfactory interruptions were rejected. Rint was expressed as the median of all satisfactory measurements. Decisions regarding admission were made independently by the clinical team, and Rint measurement of children admitted was subsequently compared with those allowed home.
Results: 27 children were assessed. Median (range) age was 4.3 years. Rint measurement was successful in 27/27 children pre-BD and 26/27 post-BD: only in 3 children were 10 acceptable interruptions not achieved. Measurements were all completed within 2 minutes. The 10
