It's one of the givens of kinetic molecular theory. It explains why hydrogen gas diffuses faster than carbon dioxide. Thus there is a greater probability that a lighter molecule like hydrogen will be able to cross a given transient empty space faster than a heavier one before the gap, so to speak, closes up.
(<60 kg) for IM injection in the deltoid muscle only if the subcutane-. ous tissue is not bunched and the injection is made at a 90Â° angle; a 1 needle is sufficient in adults weighing 130â152 lbs (60â70 kg);
A reduction in amount of bolus dosage may be needed in patients with heart failure or hepatic disease. Use slower infusion rate. For I.M. administration in all adults, 300 mg (4.3 mg/kg) in deltoid muscle has been used in early stages of acute MI.If needed, may be repeated in 60 to 90 minutes.entricular arrhythmias from MI, cardiac manipulation, or cardiac glycosides. Adults: 50 to 100 mg I.V. bolus given at 25 to 50 mg/ minute. If no clinical response, repeat bolus after 5 minutes. Donât exceed 300-mg total bolus during a 1-hour period.
