1) Identify the lab value of Marcelo's arterial carbon dioxide levels in mmHg.  Only type in numbers, no letters. Type out your answer to zero places after the decimal point (i.e   23) pH = 7.55 HCO3- = 60 mEq   2)  Marcelo's condition is determined to be:   3 answers required: respiratory or metabolic acidosis or alkalosis uncompensated or partial compensation Group of answer choices respiratory metabolic acidosis alkalosis uncompensated partial compensation

including Fick's law, what are three physical conditions that can optimize the rate of diffusion of a gas across a membrane?

An oxyhemoglobin dissociation curve is shown:In the diagram, shift of curve from A to B is caused by ? Carbon monoxide poisoning (CO)decreased 2,3-DPG concentrationStrenuous exerciseFetal hemoglobin Increased pH

Scenario: In Charles’ blood, the partial pressure of CO in the blood (0.4 mm Hg) is far lower than the partial pressure of O2, yet the percent saturation of hemoglobin by each gas is approximately equal. What does this tell you about the affinity of hemoglobin for CO?

what is the pressure gradient that moves carbon dioxide from the interstitial fluid into the systemic capillaries? 40-46mmHg, 46-40mmHg, or 95-40 mmHg.

After finishing last in the gymnastics competition (they had to cut him free from the rings), it is now time for synchronised swimming. In order to be able to breathe under water, Marco has snuck in a balloon which he will breathe in and out of while submerged. Consider how the following parameters will change over time as he continues to re-breathe from the balloon. Ignore the pressure effects of the water on Marco and the balloon. Central chemoreceptor activity Minute ventilation Plasma pH Arterial PO2 [Choose ] ✓ [Choose ] Diameter of pulmonary arterioles Decrease No change Increase [Choose ] [Choose ]

From the information given,what is the most likely explanation for the blood gas values given?

What is the role of closed suction system in controlling ventilator-associated pneumonia?

Calculate the Cardiac output per minute from the following parameter: Oxygen consumed per minute by the lungs: 200mL Oxygen content of Pulmonary veins: 200mL/L Oxygen content of Pulmonary artery: 160mL/L
