Final answer:
To assist an electrical current to penetrate deeper during stimulation, enlarging the electrodes or increasing their distance apart is suggested. Considering the body's conductivity and varying resistance levels, especially when skin is bypassed, safety protocols are strictly adhered to in medical practices to avoid the risks of electrical shock.
Step-by-step explanation:
If the current on an electrical stimulation treatment needs to go deeper, you would typically increase the size of the electrodes, or alternatively, you can increase the distance between them. Larger electrodes or increased spacing allows for a broader distribution of the current, which can reach deeper into the tissue. It's important to consider the resistance of the body, as the skin provides significant resistance when dry. When the skin is wet or when there's a break in the skin barrier (such as in surgery or from medical devices like catheters), resistance is greatly reduced, making the body more sensitive to electrical currents.
During medical procedures that involve bypassing the skin's resistance, extremely low currents are required due to microshock sensitivity. In such scenarios, larger currents could be dangerous and should be avoided. Safety standards become highly important in these sensitive situations to avoid any potential harm.
