The number of heartbeats per minute is known as the heart rate, while the volume of blood that is pumped by the ventricles with each heartbeat is the stroke volume.
A normal resting heart rate for adults ranges from 60 to 100 beats per minute. Typically, a lower heart rate at rest indicates more efficient heart function and sounder cardiovascular fitness.
Stroke volume depends on the amount of shortening that the myocardial fibers can reach when functioning against arterial pressure, The normal range of Stroke volume is 50 to 100 ml.

<span>The nurse should see first the client with new-onset of
shortness of breath (SOB) and a history of pulmonary edema. The rationale
behind this is, in light of such a history, SOB could indicate that
fluid-volume overload has once again developed. The client with a fever and who
is diaphoretic is at risk for insufficient fluid volume as a result of loss of
fluid through the skin, but this client is not the priority. Remember the rule
of assessment of the ABCs — airway, breathing, and circulation — which means
that the client suffering from SOB should take superiority over the other
clients on the unit. This client’s condition could progress to respiratory
arrest if the client were not assessed instantly on the basis of the signs and
symptoms.</span>
Seasonal and pandemic influenza are the two faces of respiratory infections caused by human-pathogenic influenza A virus (IAV) strains that often causes increased. Therefore, IAVs pose a substantial threat to global human health and are strains circulating in humans (of the subgroups H1N1 and H3N2),
