Atypical s/s of AMI in older adults - Answer-diaphoresis, SOB, N/V, AMS, syncope What differential diagnoses are most important when presenting with chest pain? - Answer-AMI, PE, PTX, aortic dissection, esophageal rupture What is considered ST elevation in men and women? - Answer-Men = 2mm Women = 1.5mm OR new LBBB in 2 leads Which troponin is more specific? I or T? - Answer-Troponin I is more specific How often to check troponins? - Answer-Q6h What 2 things can exclude PE? - Answer-Nega...

V/Q mismatch ~~> Ventilation/perfusion ratio (V/Q ratio) is a ratio used to assess the efficiency and adequacy of the matching of two variables = ventilation (V) and perfusion (P) Mechanical insufficiency ~~> Structural damage- Nervous System (alter resp rate and depth), Muscles (Abdo, intercoastal, diaphragm- (impact intrathoracic vol= dec pressure to exchange air), Airway obstruction- physiological and foreign objects (inflammation, obstructions) Medication- CNS Depressa...

Diffusion affected by ___ and ___ (thickness) of alveoli to capillary SURFACE AREA and DISTANCE Ventilation movement of air in and out of the lungs Ventilation (V) - exchange of alveolar air (gaseous flow rate) Perfusion Circulation of blood within an organ or tissue in adequate amounts to meet current needs of the cells. Perfusion (Q) - pulmonary circulation (blood flow rate; quantité = French quantity or amount) V/Q mismatch An imbalance in the amount of oxygen received in the alveoli an...

A-a gradient formula and normal range Correct Answer-PAO2- PaO2 PAO2 = FiO2 x (Patm- Ph20) - (PCo2/RQ) PAO2 = 150 - (PCO2/0.8) Normal is 10-250 Increased A-a gradient Correct Answer-- VQ mismatch (ex. COPD, PE, PNA) - responds to 100% O2 - Right to left shunt (ex. ARDs - Decreased diffusion (ex. ILD) Normal A-a gradient Correct Answer-- Low mixed venous O2 (ex. high altitude) - Hypoventilation (ex. drug OD) Acute vs chronic pH changes (hypercapnia/respiratory acidosis) Correct Ans...

Advanced Pathophysiology Exam 4 Exam Latest 2022 Normal Blood Gas Values - - pH: 7.35 - 7.45 PaO2: 80 - 100 mmHg PaCO2: 35 - 45 mmHg ventilation - - ability to clear CO2 oxygenation - - the process of delivering oxygen to the blood causes for CO2 increase - - -CO2 is being produced but not being exhaled quickly enough -increase in CO2 by increased metabolism like fever or exercise -PaCO2 in ABG is increased therefore pH decreases -as CO2 accumulates, peripheral and central chemorecep...

BCEN- respiratory Questions and answers, 100% Accurate. VERIFIED. ventilation - -movement of air in and out of the lungs Diffusion - -the process by which molecules of gas move from an area of higher concentration to an area of lower concentration (alveolar and capillary). if ventilation & perfusion match you get diffusion. If they don't match- VQ mismatch Perfusion (Q) - -the process of transporting gases to the body (capillary) via the circulatory system. dead space ventilation ...
