(OP) was calculated as the V[O.sub.2]/HR ratio, which is defined as the quantity of oxygen being consumed by the body for each single cardiac beat and it provides an estimation of stroke volume value (Crisafulli et al., 2007).
The following cardiopulmonary variables were measured: oxygen uptake (V[O.sub.2]), carbon dioxide output (VC[O.sub.2]), heart rate (HR), oxygen pulse
(V[O.sub.2]/HR), pulmonary ventilation ([V.sub.E]), ventilatory equivalents for oxygen ([V.sub.E]O2) and carbon dioxide ([V.sub.E]C[O.sub.2]).
The following parameters were recorded: heart rate (HR), minute ventilation (VE), tidal volume (TV), peak oxygen consumption (V[O.sub.2] peak), peak oxygen consumption/kg (V[O.sub.2] peak/kg), %V[O.sub.2] predicted, slope of relation between minute ventilation and C[O.sub.2] production (VE/VC[O.sub.2] slope), VE/VC[O.sub.2] ratio at anaerobic threshold, respiratory rate (RR), oxygen pulse
(O2P), oxygen saturation at peak exercise (SpO2 peak), anaerobic threshold (AT), breathing reserve (BR), heart rate recovery (HRR), and heart rate reserve (HRRes).
The maximum heart rates of each patient obtained during peak exercise and oxygen pulse
values (the amount of oxygen consumed per heart beat during exercise) were recorded.
Additional differences in gas exchange indices on CPET observed between Subjects 1 and 2 included oxygen pulse
and ventilatory equivalent for carbon dioxide (VE/VC[O.sub.2] at AT).

To release its oxygen pulse
, the conserver needed a deepish mouth inhale and I was used to shallow nose breathing through cannulas.
The CoQ10 group also experienced beneficial increases in peak oxygen consumption and oxygen pulse
Frequent references to the appendices for clarification may be necessary for readers who do not use measurements such as anaerobic thresholds, maximum oxygen uptake, or oxygen pulse
routinely in their practice.
was calculated from |Mathematical Expression Omitted~ (l/min) divided by HR max.
The ratio between oxygen consumption (V[O.sub.2]) and heart rate (HR) defines the oxygen pulse
([O.sub.2] pulse), which is numerically equal to the product of SV and the arteriovenous oxygen difference (a-v[O.sub.2] difference), according to Fick's equation (Wasserman et al., 1999).
