- The infusion pump is becoming the most commonly-used instrument for dispensing intravenous
solutions and medications to critical-care patients.
- Back-pressure in veins can reach 100 mm hg or even 150 mm hg; in arteries, it can
be as high as 300 mmhg. Gravity drips cannot always handle such pressures or detect
occlusions.
Applications
- Hormones
- Insulin
- Painkiller
The infusion pump is becoming the most commonly-used instrument for dispensing intravenous
solutions and medications to critical-care patients.
Back-pressure in veins can reach 100 mm hg or even 150 mm hg; in arteries, it can
be as high as 300 mmhg. Gravity drips cannot always handle such pressures or detect
occlusions.
An infusion pump infuses fluids, medication or nutrients into a patient's
circulatory system. It is generally used intravenously, although subcutaneous, arterial
and epidural infusions are occasionally used.
Infusion pumps can administer fluids in ways that would be really expensive or unreliable
if performed manually by nursing staff. For example, the pumps can administer injections
of as little as 0.1 mL per hour, which is too small for a drip), injections every
minute, or repeat injections requested by the patient to maintain appropriate blood
concentrations, up to maximum number per hour (e.g. in patient-controlled analgesia).
Because they can also produce quite high but controlled pressures, they can inject
controlled amounts of fluids subcutaneously (beneath the skin), or epidurally (into
the central nervous system.
