PSG 114 Week 4 Terms Questions and Answers correct

PSG 114 Week 4 Terms Questions and Answers correct CPAP (continuous positive airway pressure) A device for treating Obstructive Sleep Apnea and other sleep-related breathing disorders. Auto PAP- Auto titrating positive airway pressure (APAP) Automatically increases CPAP or BIPAP as needed to maintain airway patency and then decreases the pressure if no abnormal respiratory events are detected within a set period of time. Humidification Moisture, usually heated, which is added to supplemental oxygen or PAP to increase compliance and decrease the prevalence of certain side effects such as upper airway dryness. Bi- level PAP (BIPAP) Bi-level pressure device used to treat sleep apnea, including EPAP for exhalation and a higher IPAP for inhalation. IPAP (inspiratory positive airway pressure) Positive Airway Pressure during the inhalation or inspiratory phase of respiration. EPAP (expiratory positive airway pressure) Positive Airway Pressure during the exhalation or expiratory phase of respiration. Hypocapnea Having too little carbon dioxide (CO2) in the blood. Hypoxic respiratory drive When the drive to breathe is based off of oxygen (O2) levels rather than carbon dioxide (CO2) levels. Hyperoxemia The state of having too much oxygen (O2) in the blood. Hypercapneic respiratory drive When the drive to breathe is based off of carbon dioxide (CO2) levels in the blood. Hypercapnia Excess levels of carbon dioxide (CO2) in the blood. Timed BIPAP Switches from IPAP to EPAP based on a timed factor. Used for severe patient's. Respiratory Control. Spontaneous BIPAP Automatically detects changes in the patient's breathing and shifts from IPAP to EPAP. Patient Control. Spontaneous/timed BIPAP Auto detection but includes the safety of a timed backup to capture instances when the patient fails to breathe. Patient Assist. Split night sleep study A type of study in which the first half of the night is diagnostic (NPSG) and the second half is therapeutic with a CPAP titration. Supplemental oxygen Additional oxygen delivered to a patient, usually via a nasal cannula. ABG (Arterial Blood Gas) A test of blood taken from the arteries that shows levels of certain gases in the blood. Apnea A condition marked by the cessation of spontaneous breathing. Breaths Per Minute BPM Continuous Positive Airway Pressure CPAP Expiratory Positive Airway Pressure EPAP Exhaled Tidal Volume (VTE) The exhaled volume of each breath. High Priority Alarm An alarm signal indicating a condition that requires immediate attention. Inspiratory Positive Airway Pressure IPAP Light Emitting Diode LED LEAK The amount of airflow leak detected by the device. Low Minute Ventilation A condition in which you are not receiving a specified volume of air on a per minute basis. Low Priority Alarm An alarm signal indicating an informational message. Medium Priority Alarm An alarm signal indicating a condition that requires operator awareness. Minute Ventilation (MinVent) The volume of air received by the patient on a per minute basis. Operate State The state of the device when the device and the airflow are both on. Obstructive Sleep Apnea OSA Ramp A feature that may increase patient comfort when therapy is started. The _____ feature reduces the pressure and then gradually increases (ramps) the pressure to the prescription setting, so you can fall asleep more comfortably. Respiratory Rate (RR) The patient's rate of respiration. Normal = 12-20 bpm Rise Time The time it takes for the device to change from EPAP to IPAP. You can adjust this time for your comfort. Standby State The state of the device when the device is on, but the airflow is off. Heated Humidifier Heated water chamber that can increase pt. comfort by elimination the dryness of the compressed air. The temperature can usually be adjusted or turned off to act as a passive humidifier if desired. In general a ______ ______ is either integrated into the unit or has a separate power source (plug). Passive Humidifier Air is blown through an unheated water chamber dependent on ambient air temperature. It is not as effective as the heated humidifier, but can still increase pt. comfort by eliminating the dryness of compressed air. In general, a ______ ______ is a separate unit and does not have a power source. Exhalation Relief A comfort feature offered by two manufacturers which reduces the air flow at the time of exhalation making the breathing process more natural.
