How the Sex of the baby is determined in the womb?
How the Sex of the baby is determined in the womb? Scott 73,393 Views • 3 years ago

Your baby's sex is set at conception. At around 7 weeks, your baby's internal sex organs – such as ovaries and testes – begin to form in the abdomen. Male and female sex organs and genitalia look the same at this stage because they're derived from the same structures. At around 9 weeks, boys and girls begin to develop differently. In girls, a tiny bud emerges between the tissue of the legs. This bud will become the clitoris. The membrane that forms a groove below the bud separates to become the labia minora and the vaginal opening. By 22 weeks, the ovaries are completely formed and move from the abdomen to the pelvis. They already contain a lifetime supply of 6 million eggs. In boys, the bud develops into the penis and starts to elongate at around 12 weeks. The outer membrane grows into the scrotal sac that will later house the testicles. By 22 weeks, the testes have formed in the abdomen. They already contain immature sperm. Soon they'll begin their descent to the scrotum, but it's a long journey. They'll reach their destination late in pregnancy, or for some boys, after birth. If you're eager to find out whether you're having a girl or a boy, you'll have to wait until you're at least 17 weeks pregnant. That's when the genitals have developed enough to be seen on an ultrasound.

Obstructive Sleep Apnea Syndrome
Obstructive Sleep Apnea Syndrome samer kareem 2,030 Views • 3 years ago

What Is Sleep Apnea? When you have this condition, your breath can become very shallow or you may even stop breathing -- briefly -- while you sleep. It can happen many times a night in some people. Obstructive sleep apnea happens when something partly or completely blocks your upper airway during shut-eye. That makes your diaphragm and chest muscles work harder to open the obstructed airway and pull air into the lungs. Breathing usually resumes with a loud gasp, snort, or body jerk. You may not sleep well, but you probably won't be aware that this is happening.

Breech presentation

In breech position, the baby's bottom is down. There are a few types of breech: Complete breech means the baby is bottom-first, with knees bent. Frank breech means the baby's legs are stretched up, with feet near the head. Footling breech means one leg is lowered over the mother's cervix. You are more likely to have a breech baby if you: Go into early labor Have an abnormally shaped uterus, fibroids, or too much amniotic fluid Have more than one baby in your womb Have placenta previa (when the placenta is on the lower part of the uterine wall, blocking the cervix)

ICDs are useful in preventing sudden death in patients with known, sustained ventricular tachycardia or fibrillation. Studies have shown ICDs to have a role in preventing cardiac arrest in high-risk patients who haven't had, but are at risk for, life-threatening ventricular arrhythmias. View an animation of an ICD. Newer-generation ICDs may have a dual function which includes the ability to serve as a pacemaker. The pacemaker feature would stimulate the heart to beat if the heart rate is detected to be too slow. What is an Implantable Cardioverter Defibrillator (ICD)? An ICD is a battery-powered device placed under the skin that keeps track of your heart rate. Thin wires connect the ICD to your heart. If an abnormal heart rhythm is detected the device will deliver an electric shock to restore a normal heartbeat if your heart is beating chaotically and much too fast. ICDs have been very useful in preventing sudden death in patients with known, sustained ventricular tachycardia or fibrillation. Studies have shown that they may have a role in preventing cardiac arrest in high-risk patients who haven't had, but are at risk for, life-threatening ventricular arrhythmias.

Combitube Insertion
Combitube Insertion Doctor 10,502 Views • 3 years ago

The Combitube is a twin lumen device designed for use in emergency situations and difficult airways. It can be inserted without the need for visualization into the oropharynx, and usually enters the esophagus. It has a low volume inflatable distal cuff and a much larger proximal cuff designed to occlude the oro- and nasopharynx.

If the tube has entered the trachea, ventilation is achieved through the distal lumen as with a standard ETT. More commonly the device enters the esophagus and ventilation is achieved through multiple proximal apertures situated above the distal cuff. In the latter case the proximal and distal cuffs have to be inflated to prevent air from escaping through the esophagus or back out of the oro- and nasopharynx.
