Broncho-Cath CPAP System

Rich Man’s* CPAP *Guageguided CPAP system *Permits measuring actual pressure applied Adjust to 5-10 cmsH2O

POOR MAN’sCPAP (DLETT) 1 = BABYSAFEUnit 2 = Attached to surgical DLETT lumen 3 = O2 tubing to aux. O2port on anesthesia machine 4 = adjust flow so bag is just full(not quantitative)

CPAP with Arndt 1 = BABYSAFE system 2 = special connector (in kit) for Arndt CPAP administration through blocker lumen 3 = adjuster valve 4 = standard anesthesia circuit

X = Don’t place tight sealed catheter in endotracheal tube to try and deliver CPAP!!! It can lead to ………………. →

1 - Mediastinal Air 2 -Pneumothorax on side opposite sugery

Questions The increase in alveolar PCO2 decrease alveolar PO2 Pulmonary embolism increase the difference between the PaCO2 and ED CO2. Shunting cause mainly hypercarbia Pulmonary oedema may occur in the nondependent lung during single lung ventilation.

Questions(cont.) Application of CPAP to the nondependent lung is the least effective way to guard against hypoxia during single lung ventilation. The use of vasodilator is the appropriate way to manage hypertension during single lung ventilation. Valvular lesions of the heart have no impact on PO2 during single lung ventilation.

Questions(cont.) HPV is an all or non reflex. Decrease in FiO2 than 1% is important to guard against absorption collapse in the ventilated lung during single lung ventilation. Patients under single lung ventilation should receive below average IV fluids.

Questions(cont.) Single lung ventilation cause 50% shunting. High dose of inhalational anaesthetic is appropriate in controlling hypertension during single lung ventilation.

Questions(cont.) Hypotension increase the alveolar dead space. Physiological shunting accounts for the normal difference between the alveolar and the pulmonary end capillary PO2.
