RSP 331 Exam 3 2025

A CVICU pt. has a PAC. PCWP is 20, PAP is 35/25, PVR is 100, SVR 1600, C.O. 2.5 L/min. MAP is 60. what is likely?

When Hb is fully saturated with 02, each gram can carries how many ml of 02?

What is normal oxygen delivery with normal cardiac output?

Positive pressure mech ventilation may increase alveolar pressure & convert zone II to zone I

In an upright person, gravity causes which portion of the lung to have the greatest blood flow?

when using a swan-ganz to assess mixed venous 02 with the 02 content of systemic arterial blood, what can be assessed?

compared to systemic, this is the best way to describe the normal pulmonary circulation:

A patient with a 102 degree fever will cause what shift in the 02 curve?

Which of the following is a good example of edema associated with high PCWP?

This disease process could cause pulmonary edema from capillary permeability.

Which of the following is not a cause of an elevated PCWP and increased hydrostatic pressure?

At a normal Pa02 (100), Hb carry how much oxygen per 100ml of blood?

This is the resistance that the right ventricle pumps against, nl is 100-250 dynes

Which of the following are statements related to P50?

What is 02 content with Hb 10, Pa02 550, sat 100?

What is O2 Delivery if Ca02 is 20 and cardiac output is 2.5?

Which patient population supports the most clinical application of iNO?

What is the cause of thromboemboli associated with HbS?

this is the only condition where raising the Pa02 beyond 100 mmHg is indicated.

A PA02 of less than 60 to 70 creates what effect?

At a Hb of 15 with 100% saturation what is Hb oxygen carrying capacity?

A post op pt. has sudden SOB with a swan ganz. PCWP is 5, PVR is 450, PAP is 35/25, SVR 900, MAP 80. what is likely?

cyanosis is observed when a minimum of how much deoxygenated Hb is in the capillaries?

A pt. w/ hx of pna is critically ill. PCWP is 8, SVR 500, PVR 100. CVP is 6. C.O. is 8 L/min. MAP is 66. What is likely?

normal mixed venous sat is 75% and a Pv02 of 40 mmHg

The PA02 is higher than systemic Pa02 for what reason?

Which of the following levels of PO2 is associated with sharp decreases in oxygen saturation and content?

Calculate Ca02 and then D02 for the following data: Hb 7, sat 97, Pa02 100. C.O. 7.

the decreased affinity of Hb for 02 caused by rightward shift and by high C02 is called what?

The whole body tissues normally extract what % of 02 delivered to them?

this potential side effect of iNO causes the iron in Hb to bind to 02 and Hb unable to transport/release 02

What is the normal % sat at sea level for Hb with a nl Pa02 of 100?

In the presence of a normal PaO2, how low does the pH need to get before a significant increase in PVR is present?

Your pt. has a swan-ganz and the PCWP reading is 18. what is this reading in relation to normal values?

A blood transfusion is recommended at what Hb level?

This maneuver is a forced expiration against a closed glottis & can squeeze up to 250 ml of blood out of pulm circ?

This drug selectively dilates pulm vessels in well ventilated lung areas, lowering resistance there & diverting blood

Calculate Ca02 if Hb is 10, Pa02 is 90 and Sp02 is 100%.
