Temperature-Pulse Relationship

I've always wanted to know, the values used to determine relative bradycardia in a patient. Thankfully, I was able to encounter one article that points to a approximation. I encountered the table while I was reading on atypical pneumonias (so don't be surprised if you might be reading about it).

Temperature-Pulse Relationships (temperature and corresponding pulse [beats/min])

Appropriate Pulse Relative Bradycardia

41.1°C/106°F = 150/min <140/min

40.6°C/105°F = 140/min <130/min

40.0°C/104°F = 130/min <120/min

39.5°C/103°F = 120/min <110/min

38.9°C/102°F = 110/min <100/min

Good luck in the pulmonology exams Batch 2009-2013!

Videos:The Pulmonary Systerm and Bohr Effect

Here are two videos, I stumbled upon while doing my self-directed learning. I wish to share this with you guys.

This video shows pulmonary system including the lungs, larynx, trachea, bronchi, bronchioles, alveoli and thoracic diaphragm.




This video has a great discussion on the Bohr Effect.

What is the P2?

To understand the P2 sound, we must first be acquainted with the second heart sound.

What is the second heart sound?

The second heart sound (S2) is a short burst of auditory vibrations of varying intensity, frequency, quality, and duration. It has two audible components, the aortic closure sound (A2) and the pulmonic closure sound (P2), which are normally split on inspiration and virtually single on expiration. S2 is produced in part by hemodynamic events immediately following closure of the aortic and pulmonic valves.

Stumbled upon a video discussing COPD. This video offers information regarding COPD. Credits goes to the uploader.

How do you measure an anatomic dead space?

Firstly, what is an anatomic dead space?

The anatomic dead space is the volume of the conducting airways. The normal value is in the range of 130 to 180 mL and depends on the size and posture of the subject (Murray and Nadel's Textbook of Respiratory Medicine, 4th ed).

The normal dead space air in a young adult man is about 150 mL (Guyton and Hall, Textbook of Medical Physiology, 11th Ed.).

A difficulty with this method is that the anatomic dead space is not easy to measure, although a value for it can be assumed with little error. One milliliter per pound of body weight is a common assumption. (Murray and Nadel's Textbook of Respiratory Medicine, 4th ed).
