The Lungs in Detail By Angelica Dizon
HE LUNG REVEALED – Examine the structure and function of the components of the lungs, airways and endocrine controls that affect pulmonary function.
OXYGEN DELIVERY AND CONSUMPTION – Find out how the lung controls acid/base balance and the mechanisms that protect the body from hypoxic injury.
COMMON PULMONARY CONDITIONS – Find out what is really going on during acute pulmonary edema, COPD, and pulmonary embolism.
LESS COMMON PULMONARY DISORDERS – Discover the pathophysiologic mechanisms behind less common pulmonary disorders such as ARDS, hospital-acquired pneumonia, and pulmonary hypertension.
Slowly and silently your lungs pull air in and out several times a minute – sometimes slowly, sometimes rapidly, always with perfect control. When things go wrong, the lungs can become incredibly complex organs to diagnose and treat.
Have you ever wondered why:
- Patients who suffer respiratory arrest often complain of anxiety as much as 8 hours before they decompensate?
- Pulse oximetry can be normal when your patient is having difficulty breathing?
- Abnormal breath sounds form and what they mean?
If you have a hard time explaining to your patients about how a pulmonary embolism affects lung function or why some asthmatics can become hypoxic and stop breathing, then you need to go back to the basics with the help of a mentor who can really make the information easy and understandable.
Most of us learned our anatomy, physiology, and pathophysiology in school where we were focused primarily on passing the class. We memorized, we studied, but we quickly forgot.
Understanding the essential concepts of pulmonary anatomy, physiology, and pathophysiology will help you find patient complications faster and respond to them more appropriately. In addition:
- You will communicate more effectively with physicians and your peers,
- You will feel more confident,
- You will provide safer and more effective care!
