Truncated expiratory limb

WebThe term ‘single limb’ circuit is a commonly used misnomer when referring to the type of circuit shown here. The setup shown has a short expiratory limb and expiratory valve and functions similarly to a dual limb circuit. Because this setup has an expiratory valve, a non-vented mask must be used for CPAP/NIPPV • • The ’true’ single ... WebThe limb bud consists of loosely associated mesoderm inside an ectodermal jacket. At the distal edge of the limb bud, a thickened ectoderm forms at the dorsal–ventral boundary (see Figure 14). This is the AER. Removal of the AER results in the cessation of limb bud out-growth and a truncated proximal–distal (PD) axis.
