Abstract

It is recommended that spirometric testing in children be completed while sitting. Our experience indicates that children prefer standing during spirometry. We sought to compare spirometric results obtained from the sitting (SIP) and standing (STP) positions. Two testing sessions were performed in random order (SIP vs. STP: 30-45 min apart) in 118 children (7-13 years), attending one, randomly selected, primary school (response rate: 92%). Acceptable quality was found in 77.9% of STP and 77.1% of SIP maneuvers. Higher values of spirometric variables on STP, compared to SIP, were obtained for forced vital capacity (FVC) (2.12 ±0.41 l vs. 2.11 ±0.39 l) and forced expiratory volume in 1 s (FEV1) (1.78 ±0.36 l vs. 1.77 ±0.35 l) but the differences were not statistically significant. Relative between-position differences (RBPD) ≤ 5% were found with the following frequencies: FVC: 56.4%, FEV1: 69.2%, PEF: 21.7%, and FEF25-75: 24.3%. Similar patterns were found for FEF25, FEF50, and FEF75. Relative between-position differences were related to age in the case of FEV1 (p = 0.005), FEF25 (p = 0.02), and FEF25-75 (p = 0.01) where older children had smaller RBPD. Forced vital capacity RBPD was lower (p = 0.01) in subjects with current whee...Continue Reading

Asthma

This feed focuses in Asthma in which your airways narrow and swell. This can make breathing difficult and trigger coughing, wheezing and shortness of breath.

Allergy and Asthma

Allergy and asthma are inflammatory disorders that are triggered by the activation of an allergen-specific regulatory t cell. These t cells become activated when allergens are recognized by allergen-presenting cells. Here is the latest research on allergy and asthma.
