Arterial pressure changes during spontaneous sleep in man

摘要: Abstract The systemic arterial pressure was measured continuously during spontaneous night sleep (using a catheter in the branhial artery) eight normotensive subjects. results can be summarized as follows: 1. Arterial decreased rapidly first part of and increased gradually second part. 2. Pressure progressively from when subject still awake to successive slow stages: difference between one stage next is significant. slightly higher, but not significant degree, REM than 3. Variations particular might present both 2 stage. In 2, some subjects, these variations became periodic time time, identifiable with oscillations described by Sigmund Mayer; they were often accompanied respiratory periodicity. increases more pronounced necessarily relation arteriolar tone or heart rate.
