Using Ambien To Treat Insomnia In Shift Workers

 People who are employed in shift jobs between seven in the morning and six in the evening frequently encounter special difficulties when attempting to go to sleep. In spite of this, many recommendations for good sleeping patterns are made for people who have daytime jobs.

Around 20% of employees in the world report to work at night or on an alternate or variable schedule. While some people can adjust their sleep habits depending on their employment, the majority claim to feel exhausted during the day. There are a number of employees who works in shift report having problems falling asleep, which results in insomnia and problems remaining awake. Many dangers associated with shift employment can be attributed to an imbalance in the surrounding circumstances and inner body clock. This imbalance increases the likelihood of job mishaps, disrupts sleep, and potentially worsens health conditions including diabetes, overweight, and challenges with recall and cognition.

The new recommendations are applicable to both night shift workers and morning employees, such as keeping a scheduled bedtime, enhancing the sleep setting, and remaining conscious of the impacts of coffee, nicotine, and liquor. However, others of the recommendations are specifically tailored for shift workers. These updated recommendations provide various recommendations for shift workers to get more rest:

ü  Give your sleep top priority. Change your plans for the day and inform your loved ones about your sleep routine. 

ü  Get adequate rest each day, whether it is all at a time or during naps.

ü  For whatever kind of shift you are employed, establish a certain sleep regimen.

ü  When you first wake up and are still sleepy, stay away from potentially dangerous jobs.

ü  Cover the window through curtains or apply an eye mask to block out the sun rays

ü  Consult a physician about possible drug effects on sleep.

ü  Avoid consuming food or beverages right before bed.

ü  Plan beforehand for tough sleep times and consult a doctor if issues continue.

ü  Give yourself a quick sleep in the early hours on weekdays and go to bed sooner than normal.

These new recommendations give doable strategies for enhancing sleep and lowering the possibility of sleep loss for the countless number of shift workers who manage to feel refreshed. Additionally, they stress the significance of developing unique sleep plans for people who work when the rest of the world is asleep.

It is recommended to use Ambien (zolpidem tartrate) as a temporary remedy for insomnia characterized by problems falling asleep. The clinical investigations on Ambien have demonstrated that it can reduce latency in sleeping for a maximum of thirty-five days. The ultimate formal evaluations of sleep latency were conducted at the last phase of therapy in the controlled studies that were conducted to confirm effectiveness.

Dosage And Management

Apply the patient's lowest safe dose. The starting amount is five milligrams for females and possibly five or ten milligrams for males. It should be used one time every night, just prior to bed, a minimum of seven to eight hours ahead of the intended wake-up time. A ten-milligram dose may be used if the initial five mg dose is ineffective.

Some people may be more likely to have next-day depletion when participating in other endeavors that require total awareness due to increased morning plasma levels after taking the ten-milligram dose. The maximum daily intake of Ambien shouldn't be over ten milligrams taken right before bed. Ambien should only be used once, and it shouldn't be given again that night.

The starting doses are not the same for men and women as zolpidem clearance is decreased in women. Ambien shouldn't be used for an extended period of time. A quick course of medication is ideal as the probability of addiction and dependency grows with the length of treatment, further therapy should not be conducted without reassessing the patient's condition

PC Case


The PC case is a thin sheet metal enclosure that houses the motherboard, power supply and various drives (HDD, FDD, CD, DVD).

  • Cases are offered in two styles, desktop and tower. Today the tower type is predominant. It stands upright and is much taller than it is wide. It is usually placed on the floor next to, or under a desk. The desktop has a pizza box profile and usually sits on the desktop.

  • Tower cases are offered in two basic sizes, one that can fit ATX (12" wide) motherboards and one that can accommodate ATX mini (8.5" wide) motherboards. The number of drive bays offered also varies depending on manufacturer.

  • The motherboard and power supply mount to the floor at the rear of the case. The drives (hard, floppy and CD/DVD) mount in enclosures called drive bays at the front of the case.

Motherboard

The motherboard is the main circuit board in a PC. It contains all the circuits and components that run the PC.

Major Components found on the motherboard are:
  • CPU - the Central Processing Unit is often an Intel Pentium or Celeron processor. It is the heart of every PC. All scheduling, computation and control occurs here.

  • BIOS - Basic Input Output System is a non-volatile memory that contains configuration information about the PC. It contains all the code required for the CPU to communicate with the keyboard, mouse video display, disk drives and communications devices.

    When a PC is powered on it uses the BIOS 'boot code' to set up many required functions that bring the PC to a point where it is ready to work.

  • RTC - the Real Time Clock chip keeps date, day and time in a 24 hour format just like your watch. The PC uses this clock to 'time stamp' files as they are created and modified. When you print a file it time stamps the pages as they are printed.

  • Chip Set - these are large chip(s) that integrate many functions that used to be found in separate smaller chips on the motherboard. They save space and cost.

    The functions performed by these chip sets often broken into two devices with one providing an interface from the CPU to the memory and the other providing controllers for IDE, ISA, PCI and USB devices (see below).

Primary Connectors found on the motherboard are:
  • Power - A 20 pin connector accepts a plug from the power supply. This plug carry DC power to all the circuits on the motherboard.

  • Keyboard - A Mini-din 6-pin (round) connector found at the back of the motherboard is where the keyboard plugs in.

  • Mouse - A Mini-din 6-pin connector found next to the keyboard connector is where the where the mouse plugs in.

  • Display - This connector is not integrated into the motherboard but is included in this list since its function is absolutely necessary. It is a 15-pin, D-shell type connector found on a video card that plugs into the AGP connector of the motherboard (see below).

  • IDE - stands for Integrated Drive Electronics. These are 40 pin connectors that provide a place to connect the ribbon cables from the drives (hard and CD/DVD). All data between the motherboard and the drives is carried in these cables. They are not accessible unless the PC cover is removed.

  • FDD connector - it is similar in function to the IDE connector. It is a 34 pin ribbon connector that carries data between the motherboard and any floppy drive installed in the PC. Not accessible with PC cover on.

  • DRAM - Dynamic Random Access Memory connectors for SIMM and DIMM type memory modules. Not accessible with chassis cover on.

  • Serial Connectors

    • Standard Serial Connector - This connector has been around in PCs since they first appeared. It was originally located on ISA expansion type cards (see below). Today it is an integral part of newer motherboards. It is a 9- pin, D-shell connector that allows you to connect external devices with serial ports to your PC. The maximum data rate is 115 KB/s.

    • USB - Universal Serial Bus This is a relatively new serial bus. Originally specified as low speed, 1.2 Mb/s, it was enhanced to full speed, 12Mb/s. The latest version 2.0 is specified as high speed, 400 MB/s.

      Someday USB will completely replace the standard serial connector that has been the workhorse serial port in earlier PCs. USB is now a standard connector on all new motherboards.

      Unlike serial and parallel ports, the USB port is designed to power devices connected to it. The devices must be low power devices and must be able to reduce their current draw to less than 0.5uAmps when commanded to do so by the PC.

  • Parallel Connectors

    • Centronix or Standard Parallel - This connector has been around in PCs since they first appeared. It has 37-pins and is now integrated on new motherboards. It is usually used to connect your printer to the PC and moves data at about 1MB/s.

    • SCSI - Small Computer System Interface moves data at a maximum of up to 80Mb/s. It not integrated into most PC motherboards. It can be added to a PC as an Expansion card (see below). Some printers and hard disk drives use SCSI interfaces.

  • Expansion Card Connectors - The CPU connects to expansion card connectors through one of the chip set ICs mentioned above. They are located on the motherboard near the rear of the PC. These connectors allow special function cards to plug into and work with the PC.

    Before motherboards integrated the serial and centronix connectors they were found on expansion boards that plugged into ISA slots.

    Most PCs have the following expansion connector types:

    • ISA - Industry Standard Architecture connectors have been around since 1980 and first appeared in the IBM XT PC. This type of slot still appears on some newer motherboards so that older expansion boards can still be used. However, many motherboards no longer have ISA connectors on them.

    • PCI - Peripheral Component Interconnect is a newer and faster interface that accepts all expansion cards that have a PCI interface.

    • AGP - Accelerated Graphics Port is a connector that is designed to work with video cards. Your video display plugs into and is controlled by one of these video cards. Many modern video cards offer enhanced 3D-graphics and fast, full motion video.

Power Supply

  • A power supply is installed in the back corner of the PC case, next to the motherboard.

  • It converts 120vac (standard house power) into DC voltages that are used by other components in the PC.

  • A 20 conductor cable carries +5vdc, -5vdc +12vdc, -12vdc and ground to the motherboard.

  • Another pair of cables, each with four conductors and two 4-pin connectors daisy-chained along it, carry +5vdc, +12vdc and ground to the drives (hard, floppy and CD/DVD).

Hard Disk Drive

  • The HDD installs in one of the 3-1/2 inch internal drive bays in the PC. It is secured by machine screws.

  • It is powered by a 4 conductor cable coming from the power supply.

  • Data to and from the motherboard is carried on a 40-pin IDE (Integrated Drive Electronics) cable.

  • Data is stored magnetically on multiple rigid disks that are stacked up like pancakes. Small arms with magnetic pickups move rapidly back and forth across the top and bottom surface of each disk in the drive. The sensors float just a few microns above the rotating disk surface and can read and write data at very high rates.

  • Most commercially available hard drives rotate at 5400 or 7200 RPM (revolutions per minute) which translates to 90 or 120 revolutions per second respectively. The data transfer rate from the drive to the motherboard is 33 Mbytes/second in bursts. Newer drives are capable of higher speeds up to 66 Mbytes/sec. To use this faster drive, the PC must have an ATA/66 interface that is capable of keeping up with it.

Floppy Disk Drive

  • The FDD installs in one of the external drive bays at the front of the PC case and is secured by machine screws. External means you can access the drive from the outside.

  • It is powered by a cable with a 4-pin connector that comes from the power supply.

  • It transfers data to and from the motherboard by means of a 34 pin ribbon cable.

  • It stores data magnetically on a removable floppy disk. A pickup arm in the drive floats above the disk surface. The arm moves rapidly back and forth across the disk surface as a small magnetic sensor at the end of the arm reads and writes data on the rotating disk surface.

  • Floppy disks hold 1.44 Mbytes, which at one time was a large amount of data. Today many programs and files are much larger than this. In spite of being surpassed in size by CD and DVD, floppy drives are still found on many newer PCs.

Compact Disk Drive

  • The CDD installs in one of the external 5-1/4 inch drive bays in the front of the PC case. It is secured by machine screws. Some manufacturers offer special rail-like systems that mount on the CDD. These allow the drive to be removed from the PC without having to remove any screws.

  • Data is stored optically on the surface of the disk. A laser attached to an arm that moves back and forth across near the disk surface and sends light toward the disk surface which is coated with of a thin layer of aluminum.

  • Smooth areas called a lands reflect the light back to a photo diode located near the laser. The reflected light is read as a 1. Areas called pits are where the aluminum has been removed. When the laser light hits these, it is scattered and very little is picked up by the photo diode. The absence of light is read as a 0.

  • CDD have become the predominant removable storage media for PCs and can store 700 Mbytes of data.

  • A 4-pin cable from the power supply plugs into the CDD and provides power to it.

  • Data to and from the motherboard is carried on a 40-pin IDE (Integrated Drive Electronics) cable.
