About

The aim of the study is to evaluate the ability of ulna length to predict accurate protective lung tidal volume in Egyptian people in reference to their standing height.

Full description

After approval of local ethical committee and informed consent, one hundred healthy volunteers will be rnrolled in this study. Height of each subject will be measured while standing upright against a wall. Then, the left ulna will be measured with a measure tape from the olecranon to mid point of styloid process. From ulna length, height is estimated as advised by Malnutrition Advisory Group, British Association of Parenteral and Enteral Nutrition. October 2008. Malnutrition Universal Screening Tool.Protective lung tidal volume is calculated as 6 ml/kg predicted body weight (PBW) as follow:

PBW= 50*0.91 (centimetres of height - 152.4) in males and 45.5*0.91(centimetres of height - 152.4) in females.

Each measurement will be performed only once for each subject. Agreement between measurements will be expressed by the Bland-Altman method.
