Lung Function Research - Call for volunteers

[Reg.T]

As my figures seemed inconsistent with the others posted here I queried it. Caroline has just replied to confirm there was a typo, and my peak watts figure was 325 rather than 225.

The figures above look VERY impressive to someone like me, who is used to interpreting tests done in over-60s before surgery. Essentially, anyone with a VO2Max over 15ml/kg/min or VO2AT over 11ml/kg/min is considered "fit". So you guys would have no problem being "passed" as likely to survive a major operation....

I thought people having a major operation lay immobile while the surgeon worked...

Bugger, THAT'S where I've been going wrong......

(The relationship between exercise capacity and outcome is pretty near perfectly predictive, actually. More and more decisions made on e.g. planned ICU postoperatively or not, or chemo/radio vs surgery, or which operation, and so forth, taking CPX variables into account. Pre-op decision support has for few years been by far the most common clinical use of the test.)

I vaguely knew that

Sorry!

Does this mean anything to you lot?

Cardiopulmonary exercise data
Peak W 225
End-exercise minute ventilation
(L/min)
87.6
VO 2 max (peak oxygen uptake)
(ml/min/kg)
30
VO 2 at anaerobic threshold “ATVO 2 ”
(ml/min/kg)
18
ATVO 2 as a % of VO 2 max
(%)
Predicted = 40 to 60%
60
Respiratory muscle function data
Sniff nasal pressure (cmH 2 O) 92.7
Diaphragm electromyogram activity at rest “EMGdi% max” (%) 9.47
Diaphragm electromyogram activity at end-exercise (%) 59.6

I am no expert.
Peak power output 225 Watts
Minute ventilation is the maximum amount of gas you can shift in a minute.
vO2 Max = aerobic capacity.
