09:59 Breathing rate activity

 

Breathing rate activity instructions:

You will need: a pen and paper and a timer (e.g. a smartphone timer, a stopwatch, or a clock with a second hand). 1.  Sit quietly, breathing normally, and time exactly 60 seconds while you count the number of times you breathe in 60 seconds. A full breath in and a full breath out is counted as one breath.  After you have counted your breaths for 60 seconds, write down the result. This number is your breathing rate, which is the number of breaths you take in one minute.

2. Repeat Step 1 to measure the resting breathing rate two more times to get a more accurate result.

3. Time another 60 seconds and do some very energetic star jumps, otherwise known as ‘jumping jacks’, and try to really push yourself to jump high and go as fast as you can.

4. Stop jumping, time 60 seconds, and measure your breathing rate again, by counting your breaths for 60 seconds, and write down the result.

5. If you are feeling energetic, Repeat Steps 3 and 4, by exercising again and re-measuring your breathing rate.

Did your breathing rate change after you exercised? When you exercise, your muscle cells use up oxygen and sugar and they make carbon dioxide. Having too much carbon dioxide in the blood makes the blood more acidic. This triggers the body to breathe faster to get rid of the extra carbon dioxide from the body. Breathing faster helps your body remove carbon dioxide from the blood and it delivers more oxygen to your cells.

Cardiac Cowboys

Cardiac Cowboys

The heart was always off-limits to surgeons. Cutting into it spelled instant death for the patient. That is, until a ragtag group of doctors scattered across the Midwest and Texas decided to throw out the rule book. Working in makeshift laboratories and home garages, using medical devices made from scavenged machine parts and beer tubes, these men and women invented the field of open heart surgery. Odds are, someone you know is alive because of them. So why has history left them behind? Presented by Chris Pine, CARDIAC COWBOYS tells the gripping true story behind the birth of heart surgery, and the young, Greatest Generation doctors who made it happen. For years, they competed and feuded, racing to be the first, the best, and the most prolific. Some appeared on the cover of Time Magazine, operated on kings and advised presidents. Others ended up disgraced, penniless, and convicted of felonies. Together, they ignited a revolution in medicine, and changed the world.
