An apnea is indicated if there is an 80%/75% (Respironics/ResMed) reduction in airflow for 10 seconds compared to the average airflow over an extended period of several minutes or if there is no airflow detected for 10 seconds. Apnea/Clear Airway Apnea Detection the the Respironics System One.. An apnea is detected when there is an 80% reduction in airflow from a baseline for at least 10 seconds if there is no airflow detected for 10 seconds. During the apnea, one or more pressure test pulses are delivered by the device.
Coyotes are very dangerous. They usually do not allow you to get that close to them. The problem is if the coyote has rabies or is sick in any other way they will be very aggresive and come after you. I am not sure what you should do if confronted again.
Adapted from the book Wild Neighbors. Attacks on people by coyotes are very rare and are usually preventable through changes in human behavior. Dawn Macheca. An encounter with a coyote in the urban and suburban landscape is a rare event, even where coyotes are found in large numbers.These animals are generally nocturnal and seldom seen.ou may catch a glimpse of a coyote, however, as she moves from one part of her territory to another in search of prey (usually small mammals such as mice or voles). Observing a coyote in this manner (even during the daytime) does not mean that the coyote is sick or aggressive.
