What is the Pa0,/FI02 ratio if the PaO, is 69 mmilg and the patient is receiving 40% oxygen via venti mask? Show your work 62. What the Pa0:/FI02 ratio normal value? 63. What is the Pa02/PAO2 ratio if the Pa02 is 254 mmHg and the PA02 is 423 mmHg? Show your work

Explanation / Answer

Systolic pressure is defined as maximal arterial pressure during contraction of left ventricle of the heart.

Pulse pressure is defined as the difference between systolic and diastolic pressure readings.

Pulse pressure is directly proportional to stroke volume and inversely proportional to compliance of aorta.

Hence the answer is B. Decrease in arterial compliance and increase in stroke volume
