What is insufflation?
Insufflation (Latin: insufflare, lit. 'to blow into') is the act of blowing something (such as a gas, powder, or vapor) into a body cavity.
What is pneumatic insufflation of the colon for pediatric intussusception?
Pneumatic insufflation of the colon for reduction of pediatric intussusception has recently been recognized in the United States as an alternative method for the more traditional hydrostatic reduction with contrast material.
How do you test a pneumatic insufflator?
To test the pneumatic components of an insufflator, testing generally involves measuring the pressures, flow rate, or volume of the device. The typical pressure range for insufflators is between 10-15 mm Hg and the flow rates are less than 50 liters per minute.
What is nasal insufflation and how does it work?
Additionally, nasal insufflation can be used on patients in which intravenous access is unavailable. Insufflation devices integrate a number of sensors into their design such as pressure sensors, gas flow sensors, temperature sensors, etc.
What is a pneumatic attachment for otoscope?
A pneumatic attachment on the diagnostic head allows assessment of tympanic membrane motion by generating positive pressure in the EAC, causing the tympanic membrane to deflect medially. When pressure is released, the tympanic membrane expands laterally.
How does a pneumatic otoscope work?
The bulb on the otoscope is squeezed and released alternately create positive and negative pressure on the eardrum and assess its mobility. Absence of eardrum mobility on the application of slight positive and negative pressure indicates an infection.
What is an insufflator bulb used for?
The insufflator bulb is attached tightly to the head of the otoscope by means a tube and a tip to avoid loss of an air seal (Figure 3). A normal tympanic membrane moves 1mm medially and laterally when pressure in the external auditory canal is increased and reduced respectively.
What is an Otoscopic examination?
Overview. An otoscope is a tool which shines a beam of light to help visualize and examine the condition of the ear canal and eardrum. Examining the ear can reveal the cause of symptoms such as an earache, the ear feeling full, or hearing loss.
What is a pneumatic bulb?
The pneumatic head contains a lens, an enclosed light source, and a nipple for attachment of a rubber bulb and tubing. The head is designed so that when a speculum is attached and fitted snugly into the patient's external auditory canal, an air-tight chamber is produced.
Can a doctor see pressure in your ear?
Using a pneumatic otoscope lets your doctor see what the eardrum looks like. It also shows how well the eardrum moves when the pressure inside the ear canal changes. It helps the doctor see if there is a problem with the eustachian tube or fluid behind the eardrum (otitis media with effusion).
What is Titus media?
Otitis media is inflammation or infection located in the middle ear. Otitis media can occur as a result of a cold, sore throat, or respiratory infection.
What is meant by Tympanocentesis?
Tympanocentesis is a minor surgical procedure that refers to puncture of the tympanic membrane with a small gauge needle in order to aspirate fluid from the middle ear cleft or to provide a route for administration of intratympanic medications.
What is the use of Auroscope?
An otoscope or auriscope is a medical device which is used to look into the ears. Health care providers use otoscopes to screen for illness during regular check-ups and also to investigate ear symptoms. An otoscope potentially gives a view of the ear canal and tympanic membrane or eardrum.

How do you describe Otoscopic findings?
Typical findings on otoscopy include a bulging red, yellow or cloudy tympanic membrane with an associated air-fluid level behind the membrane. There may also be discharge in the auditory canal if the tympanic membrane has perforated.
Why do you pull the pinna down and back?
In children, the auricle should be pulled downward and backward. This process will move the acoustic meatus in line with the canal. Hold the otoscope like a pen/pencil and use the little finger area as a fulcrum. This prevents injury should the patient turn suddenly.
What is an insufflator system?
An understanding of the insufflator system design and features is helpful for any laparoscopic surgeon. There are three components to the insufflation system: insufflator, tubing equipment, and insufflation gas. The role of an insufflator unit is to establish, monitor, and maintain a constant intra-abdominal pressure during laparoscopy. A variety of vendors offer insufflation systems ( Table 8-1 ). Displayed on the face of the unit are modifiable settings for pressure and flow, alarm alerts, and real-time values for pressure, flow, and volume instilled ( Fig. 8-1 ).
What is pneumoperitoneum in surgery?
Pneumoperitoneum is the keystone that allows surgeon to create a visual field and working space necessary to conduct the operations. A basic understanding of the pneumoperitoneum process and its fundamental components is essential to create a safe and effective operating environment.
Is pneumoperitoneum a prerequisite for robotic surgery?
It is a prerequisite for any contemporary transperitoneal laparoscopic or robotic surgery and hence indicated for any such procedure. Conversely, contraindications to laparoscopic surgery disqualify establishment of pneumoperitoneum. Uncorrectable coagulopathy, hypercapnia, intestinal obstructions, limiting working space, significant abdominal wall infections, hemoperitoneum or hemoretroperitoneum, generalized peritonitis, and suspected malignant ascites may preclude establishment of pneumoperitoneum.
How to test if pneumatic system is leak free?
To do this, squeeze the bulb, place the tip of the speculum against a fingertip, release the bulb, and confirm suction on the fingertip. Advise the patient to stay still.
What is pneumatic otoscopy?
Pneumatic otoscopy is an examination that allows determination of the mobility of a patient’s tympanic membrane (TM) in response to pressure changes. The normal tympanic membrane moves in response to pressure. Immobility may be due to fluid in the middle ear, a perforation, or tympanosclerosis, among other reasons. [ 1] The detection of middle ear effusion by pneumatic otoscopy is key in establishing the diagnosis of otitis media with effusion (OME). [ 2]
Can a seal be obtained in a perforation?
A seal cannot be obtained in the presence of a perforation or a patent ventilation tube. If the tympanic membrane is fully retracted and does not move with positive pressure, break the seal, gently compress the bulb, and reexamine the ear, starting with negative pressure. This may return the tympanic membrane to a neutral position ...
Is a pneumatic otoscopy painful?
See the list below: Pneumatic otoscopy is a safe and normally pain-free procedure . On occasion, a small amount of discomfort may be experienced by the patient. If the patient has a perforation and a perilymph fistula, nystagmus, dizziness, vertigo, imbalance, nausea, and vomiting may occur (as with the fistula test).
What is respiratory insufflation?
Insufflation for respiratory assistance varies from a breathing mask (providing oxygen ) to PAP therapy devices (used to treat sleep apnea). In addition to oxygenating patients, insufflation is used to ventilate patients and to administer/maintain general anesthesia.
What is insufflation testing?
Medical Insufflator Testing. Insufflation is defined as the act of blowing something such as gas, powder, or vapor into a body cavity. There are many medical applications, the most common being surgery, diagnostics, respiratory assistance, critical care and anesthesia, and administration of drugs via nasal insufflation.
Why is insufflation important?
Insufflating gases into parts of the human body can also improve diagnostics. Insufflation can enhance radiological imaging, or provide access to parts of the body that would otherwise be difficult to examine. For example, insufflation can be used during routine colonoscopies and is often necessary in deeply sedated patients.
Why is an insufflator used in laparoscopic surgery?
Endoscopic insufflators are used in laparoscopic surgeries to create space for the surgeon to work. A lapraroscopic insufflator inflates a patient’s body using pressurized gas – commonly carbon dioxide (CO 2) rather than ambient air or oxygen (O 2) because CO 2 has fewer negative effects on the body.
How often should I test an insufflator?
Most device manufacturers will specify a service cycle in order to maintain the warranty of the insufflator – usually annually or every two years. To test the pneumatic components of an insufflator, testing generally involves measuring the pressures, flow rate, or volume of the device.
Who calibrates insufflators?
The sensors are calibrated or verified at this time by design engineers, manufacturing engineers, and technicians. Once sold and put into use by a hospital, insufflators are typically serviced either directly by the manufacturer or by an authorized service technician (trained and certified by the manufacturer).
Can nasal insufflation be used for intravenous access?
Additionally, nasal insufflation can be used on patients in which intravenous access is unavailable.
