Document Summary
" broncho dilation in response to t co2 to t airflow to the region (cid:8869) remove coz faster. " ve : minute ventilation of the respiratory system. Ve = tv ( tidal volume) x rr ( respiratory rate) ( 0. 54 breath) ( 12 breaths 1mm ) " anatomical dead space : areas where gas exchange does not occur (cid:8869) conductive pathways. In, expire 500ml za ] 150ml fresh air. Van : alveolar ventilation ( gas exchange surfaces ) Van = ( tv - ds ) x rr. [ anatomical dead space jaw = ( 500ml - 150ml ) ( 12 breaths 1mm ) = ( 350ml i breath. ) ( 12 breath. si min. ) Initially t tidal volume to t van then t respiratory rate. > composition of air with in the alveolus.
