	Stethoscope - Medgadget Wiki
		The stethoscope (Greek στηθοσκόπιο, of στήθος, stéthos - chest and σκοπή, skopé - examination) is an acoustic medical device for auscultation, i.e.
		Stethoscopes are often considered as a symbol of the doctor's profession, as doctors are often seen or depicted with a stethoscope hanging around their neck.
		Stethoscopes are also used by mechanics to isolate sounds of a particular moving engine part for diagnosis.

		On the right the stethoscope is taken apart revealing the wood screw thread that attaches the two parts of the body of the stethoscope and the chest plug with brass tube fitting that holds the chest plug in place in the funnel shaped chest end.
		On the right the stethoscope is taken apart showing the rounded wood pressure fitting which holds the two parts of the body together and the brass tube fitting which holds the chest plug in place in the funnel shaped end of the stethoscope.
		The fetal stethoscopes that emerged usually had a very wide or flaring bell and a wide earplate, which prevented the stethoscope from rocking on the abdomen of the mother during fetal auscultation.

		A stethoscope is a medical instrument used to listen the internal sounds of the body, like those produced by breathing or heart beating.
		The stethoscope was introduced by Rene-Theophile-Hyacinthe Laennec, in 1816, and was a standard until an enhanced, binural stethoscope was introduced by Arthur Leared, in 1851.
		At the moment, the stethoscope is used to aid the process of diagnosis, and, at the same moment, it has become a symbol of the medical profession itself.

	Fetus or Newborn Problems: Labor and Delivery Complications: Merck Manual Home Edition
		Fetal Distress: Fetal distress is an uncommon complication of labor.
		If a significant abnormality in the heart rate is detected, it can usually be corrected by such measures as giving the woman oxygen, increasing the amount of fluids given intravenously to the woman, and turning the woman on her left side.
		Fetal distress may be associated with postmaturity (when the placenta malfunctions in a postterm pregnancy) or with complications of pregnancy or labor that affect the woman and therefore also affect the fetus.

	Monitoring FAQ - Childbirth.org
		Fetal monitoring is defined as watching the baby's heart rate for indicators of stress, usually during labor and birth.
		Electronic Fetal Monitoring: This is an ultrasound device used during labor and birth, or during certain testing (non-stress test, contraction stress test, etc.) to record the baby's heart rate, and sometimes mother's contractions.
		Internal Fetal Monitoring: It is an internal monitoring with an electrode attached to the baby's head to record heart tones, and a pressure catheter to record contractions.

	Episodic Electronic Fetal Monitoring
		In general fetal cardiac activity is under the involuntary control of the central nervous system (cortical and subcortical influence) and the cardio-regulatory center of the brain stem.
		Fetal responses to hypoxia do not occur at random but are initiated and regulated by complex, integrated reflexes of the fetal central nervous system.
		Fetal heart rate baseline variability (BLV) is the degree to which the baseline varies within a particular band width, excluding acceleration and decelerations.

	Fetal stethoscope - Wikipedia, the free encyclopedia
		A fetal stethoscope (also known as Pinard's stethoscope or a pinard) is a listening device used in the care of pregnancy.
		The instrument is shaped like a listening trumpet and is placed on the abdomen of the woman so that the midwife or doctor can find the fetal heart sounds.
		The fetal stethoscope has mostly been replaced by the electronic sonicaid.

	Fetal Doppler Facts.org
		Another method for monitoring the fetus' health during labor is listening to the fetal heart beat with a special fetal stethoscope or doppler ultrasound device at regular intervals.
		There are two types of fetal monitors: 1) external, which are attached to the mother's abdomen and 2) internal, which attach to the infant's scalp inside the uterus.
		The fetal doppler itself may have some background noise, static, popping etc. When the fetal doppler probe is moved on the abdomen, louder popping noises may result.

	History of the Stethoscope
		In most cases, a microphone is placed within a bell or behind a diaphragm, and the microphone converts the sound in the chestpiece to an electronic signal for amplification.
		In a Thinklabs stethoscope, since the diaphragm is in contact with the body, the conversion of sound to electronics is direct, rather than using a microphone placed inside a chestpiece separated from the body by air in the chestpiece.
		Before the stethoscope was invented, doctors placed their ear next to the patient's body.

		With a stethoscope, you can hand the ear part over to the mum and she can hear the heartbeat, too, if that's really an issue for her.
		However, I've always found the fetal heart much harder to hear through a conventional stethoscope (the open end of a Pinard is generally far wider than a conventional stethoscope - and, of course, the midwife's ear is a lot closer to the baby than when listening through a stethoscope).

	BBC NEWS \| Health \| Stethoscope faces digital future
		The stethoscope has been an integral part of the doctor's armoury for more than a century.
		French physician Renne Laennec invented the stethoscope in the 19th Century - as a matter of preserving patient dignity rather than any great medical breakthrough.
		While the general principle of the stethoscope has changed little since then, its design makes it almost unrecognisable, with modifications to amplify the sound further.

	Monitoring the Baby’s Heart Rate and Contractions
		The caregiver or nurse checks fetal heartbeats and variability before, during, and after contractions, either using a fetal stethoscope to listen to the heart, or a Doppler ultrasound stethoscope, a small hand-held device which uses sound waves to monitor the heart beat.
		They are connected to video screens (at the bedside, and/or at the nurse’s station) and a printer which produces graphs of the fetal heart rate and the intensity of the contractions.
		Some sources recommend fetal scalp sampling (a procedure which takes a blood sample from the baby’s scalp to help confirm fetal oxygen levels) to determine whether a diagnosis of fetal distress is warranted, and whether interventions are necessary.

	Randomised controlled trial of intrapartum fetal heart rate monitoring -- Mahomed et al. 308 (6927): 497 -- BMJ
		As screening for asphyxia is dependent on detection of abnormalities in fetal heart rate, continuous electronic monitoring of fetal heart rate is thought to be appropriate for women in labour with a high risk of fetal hypoxia
		This study compared the abilities of intermittent electronic monitoring, a hand held Doppler ultrasound monitor, and the Pinard stethoscope to detect abnormalities in fetal heart rate and their contribution to mode of delivery and fetal outcome.
		The ultrasound monitor was better at detecting abnormalities in fetal heart rate than the Pinard stethoscope and was associated with lower neonatal morbidity and mortality, and perinatal outcome was no worse than that achieved with electronic monitoring
