Costodiaphragmatic margin: Midclavicular
8th rib
Costodiaphragmatic margin: Mid axillary

Physiological deadspace =
Anatomical deadspace + Alveolar deadspace
Minute ventilation =
V tidal * RR
Shift from Relaxed to Taut
Cl-, H+, CO2, 2,3-BPG, temperature
Shift from Taut to relaxed
O2
Cheyne-Stokes breathing: Pattern, reason
—iI|||Ii—iI||Ii—
Due to slowed feedback from PaCO2, as well as increased sensitivity to PaCO2
Kaussumaul breathing
Large wave. Diabetic ketoacidosis
Vessels: Alveolar pressure vs. Extra Alveolar pressure per volume
TLC: High Alveolar vessel pressure / Low Extra-alveolar vessel pressure
RV: Low Alveolar vessel pressure / High Extra-alveolar vessel pressure
Charcot-leyden crystals
Eosinophils
Methemoglobin: basis
Oxidized form of Hb (Fe3+); does not bind O2 as readily. Increased affinity for cyanide
Methemoglobin: symptoms
Cyanosis and chocolate colored blood
Methemoglobinemia: treatment
Methylene blue and VItamin C
methemoglobinemia: Causes
nitrates and Benzocaine
Carboxyhemoglobin: treatment
100% O2
Alveolar gas equation
PAO2 = PiO2 - PaCO2/0.8
Pulmonary vascular resistance equation
V = QR, P(pulmonary artery)-P(left Atrium) = CO*Pulmonary resistance
