Answer: 760mmHg


●● PH2O (water vapor pressure).
Answer: 47mmHg at body temperature


●● FiO2 (fraction of inspired oxygen).
Answer: 21% (at room air)


●● alveolar equation.
Answer: PAO2= FiO2 (PB-PH20) - PACO2/RQ

●● estimated creatinine clearance.
Answer: eCCr = (140-age)x mass (kg) x [0.85 if female] / 72 x [serum
creatinine in mg/dL]


●● sugammadex (bridion) warning.
Answer: *not recommended for use in those with CrCl <30mL/min


●● boyle's law.
Answer: P1V2= P2V2 *at constant T, as pressure increases, volume
increases


●● charles' law.
Answer: V1/T1= V2/T2 *at constant P, as volume increases, temperature
increases

Answer: P1/T1 = P2/T2 *at constant V, as pressure increases,
temperature increases

, ●● combined law.
Answer: P1V1/T1 = P2V2/T2 *obtained by combining boyle's, charles',
and gay-lussac's
