If the patient is apneic, then either a BVM or an automatic transport ventilator attached to a mask can be used.
Note that in both the intubating and non-intubating algorithms, there are distinctions made between transport and transport emergently. If a patient’s vital signs are otherwise stable and the airway and ventilation adequately managed, the risk-to-benefit ratio for emergent transport may be too high.
There will be times when a patient’s airway cannot be established or the patient cannot be ventilated on the first attempt.
Once these interventions are performed, the Paramedic should make a second attempt to open the airway and ventilate the patient. If, after the second attempt, the Paramedic is unable to establish a patent airway or ventilate the patient, an obstruction should be assumed. If these interventions fail, the next intervention is to rapidly troubleshoot and correct easily identifiable problems, including inadequate performance of skills, on the first ventilation attempt.
If the second attempt at ventilation fails, however, the Paramedic must consider abnormal conditions.
The failure of the third ventilation attempt signifies that the Paramedic has no additional changes in care to offer. In some regions, prehospital physician intercepts are possible and, if available, should be requested at this time as well. As with the Non-Intubating Airway Management Algorithm, a patient enters the Intubating Airway Management Algorithm by virtue of having met one of the five criteria for airway and respiratory management and by having a Paramedic capable of intubating and performing other advanced airway skills. While there is some debate as to the definition of an intubation attempt, the National Association of EMS Physicians (NAEMSP) developed a standardized reporting tool (Table 21-3). After the endotracheal tube is passed, tube position is confirmed by auscultation and another confirmation device.
The two commonly accepted additional methods of confirming tube placement are esophageal detector devices and colorimic end-tidal carbon dioxide measurement.19-21 Each of these methods has benefits and drawbacks. Once the endotracheal tube is confirmed to be in a tracheal position, it must be secured using either a commercial device or tape. If the first intubation attempt fails, however, then the Paramedic must reconsider his actions and determine the best course to increase the chances of success on the second attempt.
Once the Paramedic is ready to reattempt intubation, no more than two more attempts should be made to intubate the patient.
If the second or third intubation attempt is successful, then the tube should be confirmed with three methods, it should be secured, and the patient should be monitored and transported.
The next class of devices that are likely to succeed in at least partially securing the airway are devices designed for blind insertion into the upper portion of the airway above the glottis. It is rare that a blind insertion airway device will not provide at least some ability to effectively ventilate a patient.
If the BIAD will not pass (for anatomical reasons, injuries, etc.) or does not seem to be providing adequate ventilation, then the Paramedic must fall back on the fundamentals of airway management.
Therefore, if all previous methods of securing the airway have failed, then face-mask ventilation with a BVM or ATV and an oropharyngeal or nasopharyngeal airway is appropriate. If all other airway management modalities have failed and the patient still cannot be ventilated, then the Paramedic must assume that there is a pathological obstruction of the airway. If the surgical airway succeeds, the patient should be monitored and transported emergently.
Airway management can be one of the most life-saving tasks a Paramedic can perform for a patient. The value of an algorithmic approach to airway management has been recognized by professional organizations. If the patient’s airway cannot be managed, the patient should be transported emergently.

The AC1 test is the principal test that physicians use when diagnosing and treating diabetes. The A1C test is done by using a simple blood draw with a needle or using the finger stick method.
As previously stated, results in the lower percentage of the A1C chart are ideal, while results in the higher percentages of the A1C chart usually signify that the disease is not under control. The A1C test is an invaluable tool in monitoring the progression of diabetes and creating the most effective plan for managing the disease. Follow Us Which Factors Can Alter Blood Test Results In People With Diabetes?Contrary to popular belief, all blood tests were not created equal.
Sucrose can be extracted from sugar cane, sugar beets, date palm, sweet sorghum or sugar maple tree [21]. In the stomach, gastric acid might partly break down sucrose to glucose and fructose [8-p.396].
Individuals with celiac disease can have decreased activity of the enzyme sucrase and thus a decreased ability to digest sucrose [13], which may contribute to abdominal bloating and diarrhea. Individuals with a congenital sucrase-isomaltase deficiency (CSID) or congenital sucrose intolerance cannot efficiently digest sucrose, maltose, isomaltose, isomalt, maltotriose, maltodextrins, dextrins and starch due to lack of the enzyme sucrase-isomaltase [16,17,19].
The disorder is more common in Greenland, Iceland, Alaska and Canada; there are also some known cases in the Northern and Eastern Europe, Russia, Turkey, areas around the Black Sea, Australia and New Zealand [16,20]. Theoretically, the digestion of sucrose and subsequent absorption of glucose and fructose could be also impaired in viral gastroenteritis (stomach flu), small intestinal bacterial overgrowth (SIBO), celiac disease, Crohn’s disease, tropical sprue, intestinal lymphoma, cystic fibrosis, after gastric surgery (dumping syndrome) or in severe diarrhea of any cause, but there is lack of studies to confirm this. Sucrose as a food additive is Generally Recognized As Safe (GRAS) by the US Food and Drug Administration (FDA) [22]. Individuals with the following conditions may also benefit from avoiding sucrose: diabetes 1 and 2, hyperglycemia, reactive hypoglycemia, postprandial hypotension [33], epilepsy, fructose malabsorption, small intestinal bacterial overgrowth (SIBO), irritable bowel syndrome (IBS). According to the US Food and Drug Administration (FDA), there is no plausible evidence that sucrose, except as it is a non-specific source of excessive calories, is related to diabetes mellitus [18]. In several studies in individuals with diabetes mellitus 1 or 2, adding sucrose to meals for several weeks did increase blood glucose or cholesterol levels [24,27]. Sucrose is commercially available as sugar, table sugar, granulated sugar, confectioner’s sugar, cane sugar, beet sugar, white sugar, brown sugar, raw sugar (demerara, muscovado, turbinado), rock candy, liquid sucrose (sucrose syrup). A white, crystalline substance with a pleasant syrupy flavor and sweet taste [36]; it is more sweet than glucose and less sweet than fructose [38].
Melting point is 320-378° F (160-192° C); melting point rises with the rate of heating [45,50]. Sucrose is a non-reducing sugar [47], but it can take part in the Maillard browning reaction because it can partially break to glucose and fructose during cooking [48].

Ideally, since the patient is at least in ventilatory failure and at worst is apneic, the oxygen will be applied through a bag-valve-mask (BVM) device or, if the patient is apneic, with an automatic transport ventilator (ATV).
The equipment will depend on what skills the Paramedic is able to perform, but should ideally be available in a single bag or box and be organized, complete, and up-to-date.
If the Paramedic is successful at opening the airway and providing ventilation, then a rapid assessment of the intervention’s adequacy is performed (auscultation, observation). These differences are based on a specific list of conditions (Table 21-2), which require emergent transport (the assumption being that for all other conditions, the risks of emergent transport may outweigh any benefits). If the second attempt is successful, then, as before, the Paramedic should assess the adequacy of ventilation, insert an oropharyngeal (OP) or nasopharyngeal (NP) airway, and transport the patient. The appropriate obstructed airway management skills (Heimlich maneuver, unconscious patient abdominal thrusts, chest thrusts, or back blows) should be performed and another attempt should be made to ventilate the patient. In most of these patients, a head-tilt, chin-lift or jaw thrust, in combination with BVM or ATV ventilation, will be adequate to open the airway and provide ventilation. Therefore, between the second and third ventilation attempts, the Paramedic performs all of his skills to correct or compensate for anatomical issues, airway obstruction, and physiological defects. Therefore, the patient must be transported immediately to another provider capable of offering additional, advanced care. The top of the algorithm (Figure 21-4) is the entrance point and assumes that the patient needs to be intubated. At this point, if possible, the most experienced Paramedic should be performing or directly supervising the patient’s care.
As each unsuccessful intubation attempt will cause edema, bleeding, and patient deterioration, it is important that the first intubation attempt be the best intubation attempt.13 Conditions must be optimized through proper, working equipment and, if used, drug selection. For a breathing patient, particularly one with a primary respiratory disease such as CHF or a COPD exacerbation, nasal intubation is an excellent choice.14-18 These patients are likely to become hypoxic rapidly if medications are used to sedate or paralyze them as they have no reserve capacity.
If the endotracheal tube is correctly placed in the trachea, there should be an absence of gastric sounds.
Additionally, the use of a cervical immobilization collar and cervical immobilization device (head blocks) will minimize tube movement and the potential for displacement. If, after a total of three attempts, the patient is not intubated and no clearly correctable problem is identified, then a different approach to the specific patient is required.
If these two additional attempts are not successful, however, then the airway manager must move on with his management plan. Several terms have been used to describe these devices, including supraglottic airway devices, non-visualized airway devices, and blind insertion airway devices (BIADs). Although the airway may not be secure in the sense of having a tube beyond the vocal cords with direct access to the trachea, it is more secure than with simple face-mask ventilation. There will be patients whose airways cannot otherwise be managed due to injury or anatomy who will do well with face-mask ventilation. This obstruction may be visualized during an intubation attempt or assumed from either the patient’s disease process or simply from the failure to ventilate.
If, however, the surgical airway fails, then the patient must be transported emergently while the Paramedic attempts to oxygenate and ventilate the patient.
As has been demonstrated in the cardiopulmonary resuscitation arena, algorithms can greatly enhance consistent and correct task performance during life-threatening emergencies. If the patient has a patent airway but is unable to maintain that airway, the Paramedic should determine the cause of the disability. The Paramedic should perform the appropriate obstructed airway management skills (Heimlich maneuver, unconscious patient abdominal thrusts, chest thrusts, or back blows) and make another attempt to ventilate the patient. The A1C test differs from the common blood glucose test because it provides doctors with a steady, measured reading of blood glucose levels over a two to three month time period that does not fluctuate with food intake or other triggers like the readings given by day to day glucose testing often do.
By testing the percentage of A1C in someone’s blood, doctors can tell how well a patient has tolerated and processed glucose over the past few months. Newly diagnosed patients or patients with uncontrolled blood sugar levels can expect more frequent testing.
The blood is then tested for its level of A1C, which is the chemical that will adhere to glucose in the blood, making it easier to detect.
Sucrose is a chemical name for table sugar, which can appear as white (purified) or brown sugar. On the surface of the small intestinal wall, the enzyme sucrase breaks down sucrose to glucose and fructose, which are absorbed [9]. In one study, an ingestion of a sucrose drink (75 g in 300 mL) with added arabinose (1.5-4%) resulted in lower blood glucose levels than sucrose drink alone [14].
In one study, an ingestion of acarbose (100 mg) or guar gum (20 g) before ingestion of sucrose solution resulted in lower blood glucose spikes than ingestion of sucrose solution alone [15]. Undigested sucrose and starch pass to the large intestine, where they are fermented by normal colonic bacteria to gases [20]. Symptoms start to appear in small children after introducing starchy foods and may include abdominal cramps, bloating, flatulence and watery diarrhea after ingestion of certain carbohydrate foods [16]. Symptoms can be prevented by avoiding foods containing sucrose and certain starches [16]. In various studies, high consumption of sucrose-sweetened soft drinks was associated, but not cause-effect related, with abdominal obesity, metabolic syndrome, high triglyceride and total cholesterol levels and cardiovascular disorders [25,51].
This may be delegated to another provider so the Paramedic can continue down the algorithm. If the patient is spontaneously but ineffectively breathing, then supported ventilations with a BVM is the most appropriate intervention. Either an oropharyngeal or a nasopharyngeal airway is inserted depending on the absence or presence of a gag reflex, respectively.
If the patient’s airway cannot be managed, however, then the patient should be transported emergently.
Immediate actions should include repositioning the patient’s head and, if needed, suctioning the airway and performing obstructed airway skills. If this attempt is successful, then the Paramedic should assess the adequacy of ventilation, place an OP or NP airway, and transport the patient. In most of the remaining patients, these few corrections will open the airway and allow adequate assisted ventilation. As will be recalled, other non-intubated ventilatory support modalities should have been tried by this point. While the Paramedic is doing this, the least experienced Paramedic on the scene, who is capable of preparing the intubation and airway management equipment, should be doing so. The patient must be correctly positioned, the Paramedic must be correctly positioned relative to the patient, and lighting should be controlled as much as possible.
If the patient is not breathing, however, or has evidence of a basilar skull fracture, then an attempt at oral intubation is the next step.

Next, auscultate over both the left and right lung fields for presence of equal breath sounds.
The use of waveform capnography in the intubated patient can provide an additional layer of safety as endotracheal tube dislodgement can be identified and corrected almost immediately. Other times, the Paramedic simply recognizes that a different approach must be tried without being completely sure why the first approach failed.
By the time the third attempt has been made, the Paramedic should have maximized conditions.
For the remainder of this discussion, we will use the term BIADs when referring to these airways.
If the patient can be adequately ventilated by these interventions, then the patient should be monitored and transported. If basic and advanced obstructed airway skills do not clear the airway, then the Paramedic is left to attempt to establish a surgical airway. If available, the Paramedic may consider a physician intercept or an intercept with a more experienced Paramedic while en route to the hospital. While it does not replace clinical judgment in a specific situation, it allows a systematic approach that will enhance patient care. The results are the compared to the percentages on an A1C chart to gauge the progress of diabetes. Additionally, someone who may be exhibiting symptoms of diabetes or those who are more prone to developing the disease may undergo A1C testing at the advice of their physician. For this reason, the more glucose that is in the blood, the higher the A1C levels will be – and vice versa. A patient’s medical history and daily blood glucose levels are also important factors to be considered, along with the readings on the A1C chart. In one 2010 study in children with diabetes 1, oral sucrose was as effective as glucose in treatment of hypoglycemia [30]. Supplemental enzymes (sacrosidase) that help to digest sucrose are available [16]. Parents of the affected children may also have somewhat reduced digestion of sucrose and starch [16]. It is not high intake of sucrose or sugars alone but high calorie intake that can increase weight [6,41]. It also seems it is the consumption of total carbohydrates greater than 60% of daily calories and not consumption of sucrose by itself that increases blood triglyceride levels [18,29]. If, however, the third attempt at ventilation fails, then a change in tactics must be made. The third attempt at ventilation, therefore, is an optimized attempt.12 If this attempt fails, there is little else the Paramedic can do. During that transport, the Paramedic should continue to perform obstructed airway skills and attempt to ventilate. The algorithm directs the Paramedic toward a goal: a secure airway with adequate ventilation. Having the most experienced providers directly managing the patient’s care will optimize that care. If the right lung sounds are louder than the left, the endotracheal tube is likely in the right mainstem bronchus. The Paramedic must continue to monitor the patient for changes in respiratory status and transport the patient. Therefore, if the first intubation attempt failed, the patient must be ventilated as needed and the Paramedic must attempt to optimize the subsequent intubation attempt.
In all likelihood, further attempts will result only in more bleeding and edema and a more difficult airway to manage. The BIADs commonly used include the King LTS-D airway, laryngeal mask airway (LMA), and the esophageal tracheal Combitube. For example, in a patient with an inhalation burn and vocal cord edema, none of these devices can guarantee that air will pass through the cords to adequately ventilate the patient. Therefore, monitoring the patient’s condition over time becomes the third method of confirming device placement. If the pathology is at the level of the thyroid cartilage or above, a surgical airway will allow ventilation and oxygenation. That said, the American Diabetes Association recommends that diabetes maintain an A1C chart reading of 7% or less – which is an eAG of 170 or less.
In reality, the decision will be made based on local protocols, local standard of care, and medical direction.
An analysis of the actions performed gives insight into why, after three ventilation attempts, the Paramedic should change tactics. If it will shorten the time to access advanced care, ALS providers should intercept the transport. In short, everything that can be controlled should be so as to make the first attempt most likely to succeed. Check depth of endotracheal tube placement and withdraw the tube by 1 or 2 cm, reinflate the balloon, and reassess lung sounds. The changes made to optimize the second attempt should be based on the findings of the first attempt. Once the placement has been confirmed, the BIAD must be secured in the manner recommended by the manufacturer and the patient should be monitored and transported. If the patient improves and remains stable with face-mask ventilation alone, however, non-emergent transport can be considered. If the obstruction is at or below the level of the trachea, however, a surgical cricothyrotomy will most likely fail. The percentages from the A1C chart are converted into numeric readings that home glucose monitors give, known as estimated average glucose numbers (eAG). If the lung sounds remain unequal, then assess the patient for a pneumothorax, as discussed in later topics. In general, the esophageal obturator airway (EOA) and esophageal gastric tube airway (EGTA) should rarely be considered as they have a history of high complication rates and both require maintenance of a mask seal during use. If the patient has no other concurrent issues and the BIAD is allowing for adequate oxygenation and ventilation, then a non-emergency mode transport may be appropriate. Results in the lower percentage of the A1C chart are ideal, while results in the higher percentages of the A1C chart usually signify that the disease is not under control. Although they are still the BIADs of choice for some agencies, standard of care is moving away from the EOA and EGTA and toward one of the other devices.
