CPAP/BiPAP Titration Umakanth Khatwa, MD Copyright 2014 Boston Children s Hospital 10
Positive Airway Pressure (PAP) Therapy Stents open airways Reduces upper airway collapsibility Improves FRC (O2 reserve) Improves gas exchange Restores sleep continuity Reduces work of breathing Copyright 2014 Boston Children s Hospital 11
Indication for CPAP in Children Obstructive sleep Apnea Significant residual OSA after A&T Contraindication for T&A Family prefers non surgical treatment Post op management of OSA treatment Milder cases of hypoventilation To improve oxygenation Tracheomalacia (floppy airways) http://hubpages.com/hub/children and C Pap Adjusting to Continuous Positive Airway Pressure Copyright 2014 Boston Children s Hospital 12
Titration guidelines Adequate PAP education to patient/parent Mask fitting and acclimatization Minimum starting pressure = 5 cw Increase CPAP by 1 cw increment (at least 5 min) < 12 years (1 apnea, 1 2 hypopneas, 3 RERAs, 1 ambiguous event) > 12 years (2 apneas 3 hypopneas, 5 RERAs, 3 ambiguous events) Maximum CPAP pressure < 12 years = 15 cw > 12 years = 20 cw Copyright 2014 Boston Children s Hospital 13
Practical consideration In lab titration study Same parameters as diagnostic study Airflow measured by internal sensor (C flow) which can show flow limitation Need to have good ETCO2 / TcCO2 Good SaO2 signals Snore microphone Good belts Copyright 2014 Boston Children s Hospital 14
Split night study Usually avoided in young children Short time, tolerance, first night effect Difficult and frightening Allow time for home mask acclimatization Split criteria Should be well established and differs to each patient > 20 obstructive events in 1 hour > 30 in 2 hour At least 2 hour baseline data One REM cycle with supine position if possible Copyright 2014 Boston Children s Hospital 15
Guidelines The guidelines should not be followed in cookbook fashion Sleep tech / clinician should combine judgment and experience to apply these recommendations for best possible resultome Copyright 2014 Boston Children s Hospital 16
What to look for during CPAP titration Resolution of all apneas Especially IN supine REM if possible Resolution of all hypopneas Resolution of snoring Normalization of oxygenation Improvement in CO2 (< 50 torr) Decrease in sleep fragmentation Copyright 2014 Boston Children s Hospital 17
What to watch out for during CPAP titration Mask leak (usually < 20 25 LPM) Mask discomfort and difficulty sleeping? Re fit, modification, acclimatization C Flow for flow limitation SaO2 and ETCO2 data CPAP emergent central apneas and hypopneas CPAP emergent hypoventilation worsening baseline desaturation, shallow breathing, and or CO2 retention with increasing CPAP pressure Copyright 2014 Boston Children s Hospital 18
Contact MD Unable to tolerate CPAP Emergence of central apneas & hypoventilation while on CPAP Worsening desaturation or CO2 while on CPAP Vomiting in mask? Aspiration CPAP pressure requirement > 15 cw Copyright 2014 Boston Children s Hospital 19
Successful titration Ideal world Complete resolution of all obstructive apnea, hypopneas and snoring at least pressure possible including in supine REM Oxygenation well above 95% consistently ETCO2 < 50 torr No emergence of central apneas or hypopneas Better sleep maintenance Titration duration at least 4 hours (AASM), but usually > 5 6 hours in children Copyright 2014 Boston Children s Hospital 20
Usually what is considered successful titration (AASM) < 12 years: RDI < 2 per hour > 12 years: RDI < 5 per hour 75% reduction in RDI Copyright 2014 Boston Children s Hospital 21

TRANSITIONING A CHILD/INFANT TO PAP THERAPY Bob Chase RRT Copyright 2014 Boston Children s Hospital 32
PROGRAM OBJECTIVES 1.Increase your awareness of different strategies for successfully aiding a child to use CPA 2.Increase your awareness of the various types of interfaces available for children and several pros and cons of each choice. 3.Increase your ability and understanding of ways to customize a one-size-fits-all interface Copyright 2014 Boston Children s Hospital 33
COMMERCIAL SUPPORT/ VESTED INTERESTS 1. This program is strictly a collection of my ideas based upon a long successful history as a practicing respiratory therapist. 2. I have received no outside financial support or suggestions from any company in the development of this program Copyright 2014 Boston Children s Hospital 34
PROGRAM GUIDELINES Being Patient Being Persistent Being Creative Knowing your Equipment Copyright 2014 Boston Children s Hospital 35
BE Patient Under the age of 2 Spend periods of time each day holding just the mask on (no headgear or tubing) while trying to engage the child in some activity. Once the mask becomes less problematic move on to using the headgear to hold the mask in place. Do this only during the day while awake and with those people the child/infant feels most comfortable with. Copyright 2014 Boston Children s Hospital 36
BE Patient Under the age 0f 2 Work towards keeping the mask NOT headgear on for periods up to 60 minutes. Next with the PAP unit set at its lowest pressure of 4 cmh2o try using it during a nap period as this should offer a period when resistance will be at its lowest level. The goal here is to have the child fall asleep with the system engaged even for a short period, remove it as soon as the child wakes up. Copyright 2014 Boston Children s Hospital 37
BE Patient Under the age of 2 The major goal is to have the child fall asleep with the system engaged even for a short period of time Continue using it during a napping period for a couple of days. This may take 5 to 7 days to arrive at the point where they can sleep through the entire nap. Once this has been achieved for more than an hour, move on to using it at night. Copyright 2014 Boston Children s Hospital 38
BE Persistent This is the key element in successfully transitioning any patient onto PAP Therapy. Children and Infants under the age of 2 In my experience are the most difficult as you can t reason or bribe or cajole them but you can make a game of putting the mask on a stuffed animal and then on them. Go very slow for the first couple of days, but be persistent Copyright 2014 Boston Children s Hospital 39
BE Persistent Children 3 and up Can be offered something that they like if they will hold/wear the mask for a period of time The word NO is not an option here and make that clear from the start Entertain them when they wear it watch a favorite program with them, read a favorite story This is a time for tough love tempered with compassion Copyright 2014 Boston Children s Hospital 40
BE Persistent Take whatever amount of time you need to reach the goal of wearing just the mask for an hour. The next step is to see if they could go to sleep with the mask on Once they are able to fall asleep with the mask on for several nights then we move on to the next step attaching the tubing and engaging the unit Copyright 2014 Boston Children s Hospital 41
Be Creative Here we can take several different approaches Pressure Breathing on a PAP device is initially scary no matter what the age of the person using it We are accustomed to breathing in and out without resistance. PAP therapy allows you to breathe in easily but blocks exhalation at a certain point. The sensation is that you can t get all of the air out of your lung and therefore you can t take a full breath in. Copyright 2014 Boston Children s Hospital 42
Be Creative Pressure cont. We normally extend very little effort exhaling until you go onto CPAP The trick is to encourage the person to exhale slowly and with a little effort. This concept is more easily employed with the older child. I would always start with the lowest pressure of 4 cmh2o and gradually over a week move up 1 or 2 cm s of pressure until their target pressure was reached Copyright 2014 Boston Children s Hospital 43
Be Creative Modes of PAP Therapy Standard CPAP Auto Adjusting PAP (APAP) Keeps the pressure low with it only increasing in response to a reduction in airflow, corrects the problem then returns back to a lower pressure. BiLevel (BiPAP) Std and Auto Tends to simulate a more natural respiratory pattern. You breathe in at one pressure level and exhale at a lower one. Initially keep pressures as low as possible to encourage compliance, then bring it up to the target level over a couple of weeks. Copyright 2014 Boston Children s Hospital 44
Be Creative If a young child can fall asleep with the interface on but takes it off during the night try putting mittens on Copyright 2014 Boston Children s Hospital 45
