A/C mode, 600 Vt w/ a rate of 12, w/o spont.efforts: 7.36/CO2 65/HCO3 38/PaO2 100/ at an FIO2 .45 (COPD pt being considered for weaning)
Compensated Respiratory Acidosis w/ normal oxygenation; don't touch the PaCO2. However, the O2 is at toxic level for a COPDer. Drop FIO2 until he starts to breath on his own.
Heated Wick % humidity?
100%
Low minute ventilation alarm setting?
4
Describe how ↑ the TI can improve blood oxygenation.
this allows for a longer inhalation time for longer contact time for diffusion to take place.
A/C mode, 600 Vt w/ a rate of 12, w/o spont.efforts: 7.51/CO2 25/HCO3 23/PaO2 90/ at an FIO2 .45
Respiratory Alkalosis w/ normal oxygenation; Decrease VE (Vt or RR) or sedate w/ propaphal
Describe static compliance?
inspiratory hold of air w/ a Pplat giving the C of the lungs. (= Vt/Pplat-PEEP)
What changes in pt’s status can affect Cstat and Cdyn?
Cstat will decrease w/ resistance or ↑ w/ air-trapping; Cdyn will decrease or become less C w/ an obstruction
