![]() Typical peak flow meters are equipped with gauge markers indicating three “zones” that can be set by the patient or clinic staff to aid users in interpreting their peak flow scores. For those patients who are relatively well controlled and can sense worsening symptoms early in the course of an exacerbation, as-needed measurement is appropriate. For those patients who demonstrate a pattern of not having pronounced symptoms despite increasing disease activity, a clinician should outline daily (or more) measurement to identify deterioration rapidly and intervene appropriately. Specific instructions on how often and when an individual patient should be instructed to measure peak flow depends on patient characteristics and provider preference. It can be denoted on the meter to aid in interpretation. Typically, this number should be obtained during a period when the patient is feeling well and has just received maximal asthma therapy. Obtaining a “personal best” peak flow measurement during steady state for each patient is preferable to using published normal values, and this number should be used by both patients and clinicians to evaluate disease activity objectively. 2014 27 (Suppl 1): S4-24.The most widely accepted use of peak flow measurement is in the daily and/or as-needed ambulatory evaluation of asthma. Journal of Aerosol Med and Pulm Drug Del. The evolution of spacers and Valved Holding Chambers. Journal Aerosol Medicine 2007 20 (Suppl 1):S78-S84 An Instrumented Valved Holding Chamber with facemask to measure application forces and flow in young asthmatic children. Global strategy for asthma management and prevention. This LiteTouch mask and a low volume spacer such as the OptiChamber Diamond may help you deliver the medication quickly and comfortably to your child. ![]() The larger chambers require more breaths and more time to get all the medication from a single dose 4. Also select a low volume chamber (less then 350 mL) like the OptiChamber Diamond. Philips LiteTouch mask with its soft sculpted patient mask seal requires less pressure to contour to patient’s facial landscape - making it easy to fit with less discomfort, especially for small children than conventional VHC masks 2. Crying causes more of their medication to be inhaled into the stomach and less in the lungs where it is needed. This causes the child to cry and fuss during the treatment. To prevent leaks, you may need to hold the face mask on your child's face tightly. Leaks around the face mask can result in decrease medication being inhaled 3. It's a good idea to let your children practice using the peak flow meter in front of their healthcare professional.Ĭhildren up to 3 years of age cannot use a mouthpiece, so treatment with a spacer should be given with a face mask 1. Then, the highest reading from three attempts should be recorded as your children's peak flow reading. Repeat steps 4 and 5 two more times and write down the reading each time.Then slide the indicator back down to the bottom of the scale. Read the peak flow measurement next to the indicator, and see what color-coded section their reading is in (if their peak flow zones have been established).Blow out as hard and fast as they can, staying straight.Instruct your child to breathe in as deeply as they can, and put their lips and teeth around the mouthpiece.Move the red indicator to the bottom of the scale.Slide off the top cover and unfold the bottom cover into a handle.Guide your child to measure their peak flow value with a peak flow meter by following these steps: The peak flow meter is a simple, hand-held device which is used for measuring your child's peak flow value.
