AASM titration guidelines indicate that CPAP should be increased by _____ cm when there is atleast ____ hypopnea in patients <12 years old. Also can be increased for _____ obstrucitve apnea and _____ reras. 1 cm 1 hypopnea 1 obstructive apnea 3 reras occurs over time and is the result of consistently not getting enough sleep. Sleep Debt AASM titration quidelines indicate that CPAP (IPAP if on bilevel) can be _______________ to reduce the requiring of supplemental oxygen. Increased When G1 inputs are from an area that overlies an electrically "active site" and all G2 inputs are from an "inactive site" When both G1 and G2 inputs are from electrically active areas. Referential Montage Differential Montage What kind of calibration is to confirm amplifier function and appropriate channel response to amplifier controls. Montage Calibration Performed AFTER the machine cals and signal calibrations Any equipment that is to be reused on other patients should be sterilized by?? Pasteurization high-level disinfection process that uses water heated above 166 degrees F. According to AASM guidelines a minimum of ___ hours recorded are required. 6 AASM guidelines say you should end a MWT if 3 consecutive epochs of N1, one epoch of any other stage of sleep, or no sleep after 40 minutes What is it important that eye signals for both eyes deflect in opposite directions? It mimics conjunctive eye movements needed to be seen in REM. Sensitivity controls the amplitude displayed on a recording. It is appropriate to start with 7 uv/mm for sensitivity. When you have children, what do you have to do sometimes? decrease the sensitivity to 10 or 15. Peds waves are typically higher in amplitude than adults. What happens when a patient is over-titrated??? Complex sleep apnea AASM guidelines says an arousal should be scored when? abrupt shift in EEG lasting longer than 3 seconds, frequency greater than 16 hz, and 10 seconds of stable sleep after when in REM there must also be a EMG that lasts 1 second Posterior Dominant Rhythm _______ as children age. It is also the same as what?? increases Alpha AASM guidelines for a RERA at least 10 seconds, ending with an arousal, do not meet criteria for hypopnea or apnea Vertex sharp waves are seen in what stage normally? What region? N1 Central Regions AASM guidlines, the recommended maximum PAP when performing bilevel titrations in a patient >12 is __cm and <12 is __cm >12 is 30cm <12 is 20cm When a patient complains the sensation of suffocating during a pap titration. Air hunger When titrating supplemental oxygen for BOTH adults and pediatrics, starting 02 rate should be ___ L and increments of no less than _____ minutes apart, until Sp02 is between __% and __% 1 liter 15 minutes 88% and 94% AASM practice parameters for using humidification says it ? helps improve CPAP utilization Besides ensuring proper measurement, mask selection, and patient comfort, it is critical to what?? To pressurize it. Turn the pressure on, to see leak and if mask fits properly. The AASM guidelines recommend "exploration" of higher pressure levels during titration. When all events are eliminated included snoring. Why? They could benefit. Signal flattening in the nasal pressure monitor called Flow limitation could be occuring. AASM guidelines for increasing for unambiguous snoring for <12 and >12. <12 is 1 minute >12 is 3 minutes Loss of negative pressure in the interpleural space because of an opening to the atmosphere or into the lung is what ? What does this do to CPAP pneumothorax contraindicated for the CPAP The process of evaluating and improving processes is called? quality assurance air leaking in the mask conjunctivitis Why is it important to educate a patient importance of mask cleaning? minimize development of skin irritation, and promote pap adherence AASM guidelines recommend that all scalp and eye electrodes be at or below? 5000 ohms and 5 kiloohms AASM guidelines require apneas to be scored using what monitor? Hypopneas? Respiratory effort? APNEAS are scored using thermal sensor monitor HYPOPNEAS are scored using nasal pressure tranducer RESPIRATORY EFFORT is scored using intercostal EMG and inductance plethysmography What do you do if there is 60Hz artifact isolated in F4-M1 and it is not present in C4-M1, and the patient is in REM? By process of elimination, since it is not in C4, the problem is not M1. The interference is just F4. BUT since the patient is in REM, you should re-montage to F3. You should modify parameters to eliminate artifact and then document your actions. AASM guidelines for scoring apneas in pediatrics: It is obstructive when apnea criteria is met for how many breaths? Should there be respiratory effort seen? 2 breaths during baseline breathing there should be presence of respiratory effort throughout the entire period. This provides baseline data, which can be important as a reference when scoring and interpreting data. (Performed at beginning and end of study.) Physiological Calibration AASM guidelines for MSLTs: _______ nap opportunities seperated by ______ hour intervals If patient cannot sleep for nap, the latency is ______ 5 naps two hour intervals 20 minutes AASM guidelines for MSLTS: When is the only time a shorter 4 nap period can occur? when TWO REM periods have occured What do you need to do if the channel is squared off? decrease the sensitivity ( this decreased the amplitude so you can visualize the entire waveform ) AASM guidelines require portable monitoring to be used in conjunction with WHAT comprehensive sleep evaluation by a sleep physician? PSQI Pittsburgh sleep quality index it evaluates subjective sleep quality and disturbance over the previous month What do both the Berlin and STOP-BANG questionnaire have in common? They both assess for OSA ( the owl-lark questionnaire is used to evaluate circadian rhythm function ) For the system to require clean signals what channel is the most important to keep secure? Reference Channels If these channels are compromised all of the channels will be effected negatively. Proper way to clean EEG cup electrodes? Remove gel with soft tissue brush, electrodes can soak in 1:10 bleach water for 10 minutes and hang dry. Remember EEG do not come in contact with mucous membranes so pasteurization is not required NO ALCOHOL OR ACETONE A patient comes in with a order of 0 liters of oxygen but says they are currently on a 3 liters. What should you do? There may be a reason physician ordered 0, but check with them first incase. An invasive blood test procedure that is performed by puncturing an artery, typically at the wrist. Arterial blood gas A breathing disorder that affects some obese patients. Poor breathing causing hypoventilation and little oxygen that causes hypoxemia. ( there are two names ) Obesity hypoventilation or Pickwickian Syndrome Sedatives that are used to treat insomnia by aiding the initiation and maintenance of sleep. Zaleplon and zolpidem shortened sleep latency and increased sleep efficiency. Do not decrease REM Hypoxemia is what? Hypercapnia is what? Both of these are criteria for diagnosing what? Hypoxemia is an abnormally low amount of oxygen in the blood. Hypercapnia is excessive carbon dioxide in the blood Both are criteria for diagnosing hypoventilation AASM guidelines for scoring Rhythmic Movement Disorder: Frequency is ___ to ____ Hz minimum of _____ movements minimum amplitude requirement is a rhythmic bursts of ________ times the background EMG activity .5 Hz to 2 Hz 4 movents 2 times the background EMG activity Three more PVC's in a row is what?
