A patient with advanced chronic obstructive pulmonary disease is admitted to the ICU.  The patient is placed on 24% air entrainment mask and has a pulmonary artery catheter inserted.   PVR  720 dynes PaO2  57 torr The physician orders an increase to 28% oxygen via air-entrainment mask, after the increase in O2, PVR 400 dynes PaO2 72 torr What would you recommend?

Pulmonary vascular congestion is likely to begin when the PCWP reaches:

Gender roles, such as the traditional expectation that men are assertive and women are nurturing, are examples of role differentiation.

Calculate P/F ratio

When assessing your patient in ICU, you note the CVP has increased from 4 mmHg to 14 mmHg.  Concerned with an inaccurately high reading, which of the following bedside assessments would estimate the patients CVP.

A 65-year-old woman with a history of COPD was discovered unconscious at home 4 hours ago. She is now intubated and is receiving mechanical ventilation.  A flow-directed pulmonary artery catheter has been inserted. Relevant data below.  Pulse    136/min Blood pressure    76/60 mmHg Pulmonary artery pressure    17/6 mmHg Pulmonary capillary wedge pressure    4 mmHg Cardiac output   3.8 L/min Systemic vascular resistance    1354 dynes/sec/cm-5 Central venous pressure    1 mmHg The most likely cause of this patient’s hypotension is

Role strain occurs when an individual feels comfortable meeting the expectations of a particular role.

Role adaptation refers to how individuals adjust their behaviors and priorities when transitioning into new roles, such as parenthood.

Social role theory suggests that human behavior is entirely based on individual personality traits, not on social roles.

What effect would hypervolemia and pulmonary edema have on pulmonary artery pressure?
