Term
| CPAP (Continous Positive Airway Pressure) |
|
Definition
| remains the preferred and most widely-used therapy for Obstructive Sleep Apnea(OSA). |
|
|
Term
| Alternative treatments for OSA |
|
Definition
| pillar implants, dental appliances, throat lubricants, snore strips, and many different surgeries designed open the airway to allow inhaled and exhaled air to pass freely. |
|
|
Term
|
Definition
| is a non-invasive method of treating OSA that a majority of patients are able to tolerate. |
|
|
Term
|
Definition
| works by filtering normal room air (21% O2). and applying it to blower. |
|
|
Term
|
Definition
| is measured in centimeters of water pressure (cmH20). |
|
|
Term
| CPAP Mask fit snugly against the face |
|
Definition
| the air pressure works like mechanical splint to hold the patient's airway open. |
|
|
Term
|
Definition
| the patient is able to inhale and exhale normally without obstruction, and without interrupting sleep. |
|
|
Term
|
Definition
| are used throughtout the lifetime. |
|
|
Term
|
Definition
| the obstructions in the upper airway will often be reduced or eliminated. |
|
|
Term
| side effect occur with CPAP use |
|
Definition
| 1. nasal and upper airway dryness.(heat humidifier) 2. tolerating the air pressure)desensitization) 3. facial soreness (properly fit the mask) |
|
|
Term
|
Definition
| designed for diagnostic use in the sleep lab often have capabilities that far exceed those of home units. -options for remote monitoring and controlling, live output data for recording on the polysomnograph, leak mesurements, and the ability to switch modes between CPAP, Bi-Level PAP, and Auto Pap. |
|
|
Term
|
Definition
| involves gradually adjusting CPAP levels during a patient's sleep until the upper airway obstructions are corrected to a satisfactory degree. |
|
|
Term
|
Definition
| is the same as a dignostic study with the addition of a CPAP Pressure channel and a CPAP Flow channel |
|
|
Term
|
Definition
| 1. Respiratory Disturbance Index (RDI) <5 events/hour 2. SpO2>90% 3. EEG Arousals and Respiratory Effort Related Arousal(RERA)<5/hour 4. Snoring eliminated |
|
|
Term
|
Definition
| should educated the patient about untreated obstructive sleep apnea and the potential benefits of using CPAP. |

Term
|
Definition
| is increased 2cm at a time while at low pressures and 1cm at a time at higher pressure |
|
|
Term
|
Definition
| between pressure increases to allow the patient to become accustomed to the pressure |
|
|
Term
| increasing CPAP too quickly can lead to |
|
Definition
|
|
Term
|
Definition
| A decrease in airflow for at least 10 seconds caused by a partial obstruction in the upper airway. |
|
|
Term
| Respiratory Effort Related Arosal (RERA) |
|
Definition
| An EEG arousal caused by a decrease in airflow that does not qualify as an apnea or hypopnea. |
|
|
Term
| CPAP is typically increased for |
|
Definition
- Obstructive apneas
-Hypopneas
-Snoring
- EEG Arousals
- RERA's
-Oxygen Desaturations |
|
|
Term
|
Definition
| increase the pressure during inhalation and descreased it during exhalation. |
|
|
Term
| (IPAP) Inspiratory Positive Airway Pressure |
|
Definition
|
|
Term
| (EPAP) Expiratory Positive Airway Pressure |
|
Definition
|
|
Term
| 2 main purposes of Bi-Level PAP |
|
Definition
1. treat central sleep apnea
2. to increase patient tolerance of PAP |
|
|
Term
|
Definition
| A complete cessation of airflow and respiratory effort for at lest 10 seconds during sleep. |
|
|

Definition
|
|
Term
| Hypoxic Respiratory Drive |
|
Definition
| When the drive to breathe is based off oxygen levels rather than carbon dioxide levels. |
|
|
Term
|
Definition
The state of having too much oxygen in the blood.
The state of having too much oxygen in the blood. |
|
|
Term
| Hypercapneic Respiratory Drive |
|
Definition
| When the drive to breathe is based off of carbon dioxide levels in the blood. |
|
|
Term
| titrating Bi-Level PAP the IPAP is always higher than EPAP |
|
Definition
most sleep lab protocols require at least a 4cm difference between the IPAP and EPAP.
. |
|
|
Term
|
Definition
| A type of sleep study in which the first half of the night is diagnostic and the second half is therapeutic with CPAP titration. |
|
|
Term
|
Definition
| may be used in the sleep lab increase the baseline SpO2. |
