surgical cricothyrotomy

before carbon dioxide can be eliminated from the body and detected with capnography the body must be able to metabolize oxygen in order to produce carbon dioxide aerobic metabolism. patients in cardiac arrest especially prolong cardiac arrest or severely acidotic the cells are metabolizing carbon dioxide and producing lactic acid and a rabbit metabolism. as a result minimal or no carbon dioxide is being produced and returned to the lungs. this would result in a persistently low 45, he or she has excess carbon dioxide that needs to be eliminated there for you should increase the rate of ventilation

yeah

crackles formerly called rails, with your fine moist than sounds that are difficult to auscultate represent fluid in the mall lower airways and are indicative of early pulmonary edema example congestive heart failure. rhonchi or loud rattling sounds that are often heard without a stethoscope and are indicative of fluid in the larger airways severe pulmonary edema. bronchospasm typically presents with wheezing not crackles urraca.

yeah

during phase 1 a b, Dead space is passing by the CO2 sensor, since Dead space gas does not contain CO2 to the waveform is flat. during phase 2 BC that space gas rapidly mixes with alveolar gases, which is very rich in CO2, this results in acute vertical increase in the baseline called the expiratory upstroke. phase 3 CD is called the alveolar plateau, during this phase alveolar gas is continuing to move past the CO2 sensor. The end of phase 3 point d is called entitled CO2 etco2. face forward de is when the patient inhales because inhalation rapid displays to CO2 the waveform abruptly returns to baseline resulting in inspiratory downstroke

yeah

etomidate amidate is a non barbiturate, sedative hypnotic drug that is used to induce station to administering a neuromuscular blocking agent paralytic. other common sedatives include my dad's Alam versed and ketamine ketalar. sedatives and paralytics are used in conjunction to facilitate orotracheal intubation than patients who require advanced airway management, but would otherwise not tolerate Lorenzo. e. succinylcholine chloride anectine, vecuronium bromide North Korean, and recurring bromide the ramen are neuromuscular blocking agents that induce chemical paralysis, they function at the neuromuscular junction and relaxed skeletal striated muscle by impending the action of acetylcholine. it is important to note that paralytics do not sedate a patient

yeah

physiologic Dead space is any portion of the lower respiratory tract in which gas exchange does not occur because of abnormal processes such as alveolar collapse at type of paces, alveolar damage, or fluid in the alveoli. because COPD causes destruction in the inner lining of the alveoli, physiologic Dead space increases in patients with the disease. approximately 30% of a person's tidal volume remains in the anatomic Dead space, the trachea and the lunch bronchi, and never makes it to the lungs to participate in pulmonary respiration. unlike physiologic Dead space, which increases in size in patients with respiratory diseases, the size of anatomic Dead space remains relatively consistent.

yeah

the normal inspiratory expiratory i e ratio is 1 to 2, which means that normal exhalation takes twice as long as inhalation. as air becomes trapped in the lungs, such as what is seen as broncos spazmatic presents asthma or COPD, the expiratory phase becomes prolonged and the patient attempts to empty as much air from the lungs is possible. this would increase i e ratio, in some cases by as much as four or five times. none of the other conditions listed would cause a prolong exhalation time.

yeah

the paramedic should suspect that the patient has an underlying medical metabolic acidosis secondary to ketoacidosis. patient breathing pattern is consistent with kussmaul respirations, which is the respiratory system's attempt to create a compensatory respiratory alkalosis. hyperventilation drives the bodies carbon dioxide level down this would cause a low less than 35 entitled CO2 value and small capnography waveforms. high above 45 in title CO2 and large capnography waveforms are consistent with CO2 retention such as what you would expect when a patient is hypoventilating opioid overdose or respiratory failure or rost

yeah
