E cu membrana rigida, E cu Hb crescuta<br />

• ex: drepanocite, sferocite, E contractate neregulat<br />

• mai putin deformabile decat E normale<br />

supraestimarea VEM<br />

E in semn de tras la tinta (codocite)<br />

• Doua zone de Hb: centrala <strong>si</strong> periferica<br />

• Trecerea unui E prin apertura poate genera doua pulsuri de amplitudine ↓<br />
