The reservoir bag collapses on inspiration. You're treating an adult patient who is wearing a non-rebreather. An oral airway will not be tolerated with a patient with an intact gag reflex. You do not want to use the wrong size airway or it will not be effective. Try the other nostril and be sure you have lubricated the airway. You attempt to place a nasal airway in his right nostril, but you meet resistance and cannot insert. You have an unresponsive patient with an intact gag reflex. What side effect should you watch for from the MDI?Īlbuterol, a bronchodilator used to treat asthma, may cause cardiovascular side effects such as increased heart rate. Your local EMS policies allow you to help a patient self administer the MDI. The patient has a doctor's prescription to take 4 puffs of an Albuterol MDI every four hours as needed. You have a patient who has a history of asthma and is having shortness of breath. The jaw thrust technique should be used to open the airway if a cervical injury is suspected. The patient was in a car accident and injuries are not entirely known. Placing a cervical collar and then doing a head tilt-chin lift doing the jaw thrust maneuver Opening his mouth wide, while slightly hyperextending his neck You arrive on scene to a car accident and are treating a 35 year-old patient. The left lung only has two lobes because of the room needed for the heart, which is on the left side. The left lung has two lobes including the upper and lower. There are three lobes on the right lung including the upper, middle and lower. Placing a non-rebreather or nasal cannula will not be sufficient since he has a poor spontaneous respiratory effort The lungs are made up of how many lobes? A RR of 4 is too low and he needs ventilatory support. The patient is not ventilating adequately. Placing a nasal airway and a non-rebreather with an oxygen flow of 10 LPM performing manual ventilation with supplemental oxygen Performing manual ventilation with supplemental oxygenĪdministering supplemental oxygen with a nasal cannula at 2 LPMĭoing a head tilt-chin lift maneuver, placing an oral airway and transporting He has a pulse, a respiratory rate of 4 breaths per minute, breaths are very shallow and he is grunting slightly. A football player collapsed to the ground. You're on scene at a high school football game. It's also essential to have a tight seal between the patient's face and the mask or air will escape and not be delivered to the patient's lungs. To ensure ventilations are effective, make sure the airway is open by repositioning the head. Reposition the head and make sure you have a tight seal with the mask. Reposition the head and make sure you have a tight seal with the mask.ĭo a finger sweep of the mouth to make sure it's clear. Put down the ambu bag and start mouth to mouth resuscitation using a barrier device. The patient is connected to a pulse oximetry and the oxygen saturation reading is 80. You are manually ventilating a patient using a bag valve mask (BVM). If higher flow rates are needed to maintain adequate oxygen levels, switch to another device, such as a simple mask or non-rebreather. A nasal cannula can be run at how many LPM?Ī flow of over 6 LPM will not increase the delivered FIO2 and may dry the mucus membranes and be uncomfortable. In a child, manual ventilation should be performed at a rate of 1 breath every 3 to 5 seconds, for a total of 12 to 20 breaths per minute. To maintain adequate perfusion, manual ventilation should be performed at a rate of 1 breath every 5 to 6 seconds in an adult, for a total of 10 to 12 breaths a minute. The carbon dioxide then leaves the alveolus when you exhale and the oxygen-enriched blood returns to the heart.If manually ventilating a patient, you should squeeze the bag every _ seconds for an adult and every _ seconds for a child. This exchange of gases occurs rapidly (fractions of a second). The concentration of carbon dioxide is high in the pulmonary capillary, so carbon dioxide leaves the blood and passes across the alveolar membrane into the air sac. Carbon dioxide is also released from sodium bicarbonate dissolved in the blood of the pulmonary capillary. The oxygen binds to hemoglobin and the carbon dioxide is released. At the beginning of the pulmonary capillary, the hemoglobin in the red blood cells has carbon dioxide bound to it and very little oxygen. Within each air sac, the oxygen concentration is high, so oxygen passes or diffuses across the alveolar membrane into the pulmonary capillary.
