increased BP

Example of Absolute Shunting
Ans: ARDS
Example of High Ratio
Ans: Cardiogenic Shock
Acute Respiratory Distress Syndrome (ARDS) definition
Ans: Syndrome characterized by sudden, progressive pulmonary edema,
increasing bilateral infiltrates on CXR, hypoxemia refractory to oxygen therapy,
decreased lung compliance
S/S of ARDS
Ans: Rapid onset of severe dyspnea, restlessness, tachycardia, hypoxemia that
does not respond to supplemental oxygen, BNP less than 100
Management of ARDS
, 2 Exampromax - Stuvia US 2025/2026

with COPD. It provides appropriate levels, thus avoiding the risk of suppressing
the hypoxic drive.

Nonrebreathing Mask
Ans: A face mask and reservoir bag device that delivers high concentrations of
oxygen. The patient's exhaled air escapes through a valve and is not rebreathed.
Partial Rebreathing Mask
Ans: A mask similar to the nonrebreathing mask but without a one-way valve
between the mask and the reservoir; room air is not drawn in with inspiration;
residual expired air is mixed in the mask and rebreathed.
Concentration of Oxygen in Room Air
Ans: 20-21%
Oxygen Toxicity Cause
Ans: Oxygen concentrations greater than 50% for extended periods of time
(longer than 24 hours) can cause an overproduction of free radicals that severely
damage cells.
