What is a pressure bag?

The pressure bag is a device used to pressure on pressure filled with intravenous fluid to regulate how quickly the fluid is issued to the patient. Sometimes they are also called pressure pumps, pressure bags can be used in many clinical environments. Companies that produce pressure bags usually sell several different versions, including one -off units intended for use with a single patient who are thrown out after one use. This reduces the amount of time and energy spent on sterilization and storage. For the basic drip, a bag of fluids can be increased to the pole above the patient, while gravity performs work. For clips, some fine tuning may be possible. The use of a pressure bag increases the flow rate by vacuuming the bag and enforcing the content faster.

The pressure bags are inflatable cuffs that can be manually inflated to the required pressure level. The drip speed can be controlled by increasing or lowering pressure. Emergency release valves allow care providers to alleviatepressure if there is a problem. Historically, people improvised pressure bags by putting the bags under the patient and using the patient's weight as a pressure source or inflating the blood pressure cuff around the IV bag. The pressure bag is a somewhat noisier solution to the problem.

The main complication that can occur when using a pressure bag is the risk of bursting a liquid bag. This will not hurt the patient, although it may be surprising, and if the bag is filled with something like a blood product or a dangerous medicine, it can pose a security risk to the healthcare provider in the room. Pressure valves are installed to limit the possibility of such events and care also use their judgment in inflating the pressure bag.

For highly controlled supply of intravenous fluids, the patient may be attached to an infusion pump. Infusion pumps can supply very accurate doses of drugs during the period of time programmed to the device, which can be hours or days. They areEspecially useful when patients need only a small amount of drug or when it is necessary to firmly control an intravenous drop to reduce the risk of giving too much a patient.
