Priming Metered Dose Inhalers (MDIs) require priming. Priming of the inhaler is necessary for effective use of the MDI inhaler and to deliver a correct amount of dose into the lungs. Priming means to make your inhaler ready for use.
What is priming and why is it important?
Priming means to make your inhaler ready for use. Priming is done when the inhaler is being used for the first time or if it is used after a long interval of time. Different MDI types have different priming instructions:
What is priming of inhaler?

How does a priming pump work?
In its priming mode, the pump essentially acts as a liquid-ring pump. The rotating impeller generates a vacuum at the impeller’s ‘eye’ which draws air into the pump from the suction line. At the same time, it also creates a cylindrical ring of liquid on the inside of the pump casing.
Do centrifugal pumps need priming for first time operation?
However, for the first time operation all pumps need priming to avoid overheating and failure by dry running condition. In a centrifugal pump, liquid is pushed from suction to discharge. The pump works by the transfer of rotational energy from the impeller to the liquid.
Why should you prime your inhaler?
When an inhaler is new, has not been used for seven days, or has been dropped, steps need to be taken to make sure the medicine is mixed in with the propellant. This is called “priming” an inhaler. When an inhaler is not primed, the person taking it does not receive a full dose of medicine.

Can you use a spacer with DPI?
USING AN MDI & SPACER /DPI The use of a spacer helps to deliver the medication from certain metered dose inhalers (MDI) more effectively into the lungs. Proper technique is important when using either an MDI or a dry powder inhaler (DPI).
How do you prime an inhaler spacer?
If a new spacer has to be used immediately, you can 'prime' the spacer by firing at least multiple (at least 10) puffs into it to begin with to help reduce the static build-up inside. You can then take your medication dose as usual.
What happens if you drink water after inhaler?

The spacer helps deliver the medicine directly into the lungs, instead of the mouth and throat, and therefore increases the effectiveness of the medication by up to 70 percent.
Can you overdose on an inhaler?
Adrenergic bronchodilators overdose is when a person takes too much of a certain type of asthma medication. Adrenergic bronchodilators are inhaled medications that open up your air passages to help you breathe more easily. Taking too much of these medications can cause an overdose.
What happens if you don't take your asthma pump?
Patients may quit taking their medication because they feel fine. All it takes is a trigger such as a cold, allergy, chemical irritant or air pollution to send you into the danger zone. Skipping your medication, even when you don't have symptoms, could mean more flare-ups and worsened asthma in the future.

How to achieve natural pump priming?
Natural pump-priming can be achieved by maintaining the impeller eye below the surface of the water. So, naturally, water will flow into the suction pipe and casing removing all the air present by gravitational force as shown in Fig. 2
When is Pump Priming Required?
So, if the air or other gases present inside the pump casing and suction line, it must be primed before starting. But if the pump suction line and the casing are already filled with liquid during start-up, priming is not required. The main reason behind locating most centrifugal pumps below the liquid source level is that the pump remains primed automatically. Refer to Fig. 1 below that clearly explains the requirement of priming a pump.
How does a self priming pump work?
Once, all the air from the suction pipe is removed, the pump operates dynamically like any other centrifugal pump. So, A self-priming pump can lift fluid from a level below the pump and evacuates the air of the suction line without using other external auxiliary devices.
How is pump priming done?
In the manual method (Fig. 3) of pump priming, pumping liquid is filled in the pump suction by manually pouring liquid directly in suction using a funnel. The pump is manually primed due to gravity feed and the air present escapes through the air vent valve.
How does a centrifugal pump work?
In a centrifugal pump, liquid is pushed from suction to discharge. The pump works by the transfer of rotational energy from the impeller to the liquid . In between the suction and discharge sides of the pump, there are no seals. For this reason, when the liquid level is below that of the impeller, centrifugal pumps are ineffective with gases ...
Why is my pump not priming?
Majority of the pump problems are started with not priming a pump or not doing it properly. Problems associated with lack of priming usually cause financial impact due to pump maintenance and the downtime of piping system due to a malfunctioning pump. So for proper reliable operation pump must be primed.
What are the advantages of self priming pumps?
The main advantages that self-priming pumps provide are: 1 Can handle a variety of liquids 2 Work well with slurries, corrosive liquids, and suspended solids 3 Self-priming centrifugal pumps will continue to pump liquids even after the pump is not submerged in a liquid tank or vessel 4 As the steps involving pump priming on start-up are eliminated, they are ideal for frequent and intermittent pumping operations.
Why do you need a spacer for a pMDI?
A spacer should be used with pMDIs to help the medicine reach your lungs, especially if you find it hard pressing the canister or button and inhaling at the same time. 10 The spacer can also help prevent you from getting oral thrush if you are taking an inhaled corticosteroid (ICS) with the pMDI. 10.
Can you breathe in too fast with a DPI?
Breathing in too fast or too slow—DPIs need rapid deep breaths in and pMDIs need slow deep breaths in for best results. Some people with COPD may not have the ability to breathe in fast and deep while using a DPI. 13 If you have concerns, make sure you talk to your doctor or pharmacist who can advise you on correct inhaler technique.
WHAT IS PUMP PRIMING?
Priming simply means preparing or getting something ready for operation.
Why is priming necessary in centrifugal pumps?
Most centrifugal pumps are not self-priming. In other words, the pump casing must be filled with liquid before the pump is started , or the pump will not be able to function. If the pump casing becomes filled with vapors or gases, the pump impeller becomes gas-bound and incapable of pumping.
WHAT ABOUT SELF-PRIMING PUMPS?
A self-priming centrifugal pump is able to overcome the problem of air binding by mixing air with water. After it gets rid of the air, the pump will continue to move water like a standard centrifugal pump.
How to start a pump with a pump?
1: First of all the suction pipe and impeller is completely filled with water. 2: The delivery valve is closed and the pump is started. 3: The rotating impeller pushes water in the delivery pipe, opens the delivery valve and sucks water through the suction pipe.
What are the phases of a self priming centrifugal pump?
A self-priming centrifugal pump has two phases of operation: priming mode and pumping mode.
How to prime a pump?
3: Suction isolation valve. Following are the steps to priming the pump: Slowly open the suction isolation valve. Open the air vents on the suction and discharge piping until the pumped fluid flows out. Close the air vents.
How to open a pump before operating?
Open the valve in the outside supply line until only liquid escapes from the vent valves. Close the vent valves. Close the outside supply line. Priming a pump is probably the first and one of the most important things you should do before operating it.
