The Patient Imagine if you will a patient with difficulty breathing is laying on the stretcher in the back of the ambulance. Their shortness of breath is turning into an inability to speak and the patient has a scared look in their eyes that tells you that they need serious help. The medics can see […]

Partial Rebreather Mask Delivers oxygen concentrations between 60% to 80%. Partial Rebreather Mask does not have a valve covering the oxygen enrichment bag thus allowing the patient to re-breathe some exhaled gases. Flow rate is adjusted to keep the bag inflated (just like a non rebreather mask) but expect between 10 – 15 lpm. Tracheostomy […]

Air Is A Type of Fluid When most people hear the word “fluid,” they usually think of liquid. However, gasses, like air, are also fluids. Fluids take on the shape of their containers. Fluids generally do not resist deformation when even the smallest stress is applied, or they resist it only slightly. We call this […]

Problems with ambient air can cause a patient to inexplicably experience shortness of breath. Imagine a situation where a patient is struggling to breathe but there is no history of medical problems. Perhaps the patient’s problem is the ambient air. Various situations that affect ambient air can result in hypoxia: Enclosed Spaces – Carbon dioxide […]

At georgiaemsacademy, we teach that patients who are not alert may need positive pressure ventilation and that patients with rapid respiratory rate or demonstrated work of breathing need oxygen via non rebreather mask. It’s easy to keep things that simple if you are primarily looking at ventilation as all one has to do is count […]

If we’ve said it once, we have said it a million times. People that need to be ventilated (with a bag valve mask) are, for the most part UNCONSCIOUS, or minimally not alert. The vast majority of time, a person who is just having shortness of breath will not let you bag them (try as […]

With Hypoxia, The Cell Goes To Plan B Hypoxia is a physiological cue that impacts diverse physiological processes, including energy metabolism, autophagy, cell motility, angiogenesis, and erythropoiesis. One of the key cell-autonomous effects of hypoxia is as a modulator of cell proliferation. For most cell types, hypoxia induces decreased cell proliferation, since an increased number […]

Less Going In Means Less Going Out The pipe is under constant pressure, but what happens to the water when a big chunk of ice forms and blocks the pipe? The incoming flow will be obstructed, limited the amount of water the pipes will deliver. The same thing happens when an obstruction occurs in the […]

Asphyxia or asphyxiation is a condition of deficient supply of oxygen to the body which arises from abnormal breathing. Asphyxia causes generalized hypoxia, which affects primarily the tissues and organs. There are many circumstances that can induce asphyxia, all of which are characterized by the inability of a person to acquire sufficient oxygen through breathing […]

Cellular Respiration is the process used by animal cells to convert nutrients to energy (ATP), and then to release waste, such as CO2. Photosynthesis is the process that plants cells use to convert light, water, and carbon dioxide to energy, and then to release waste in the form of oxygen and glucose. All Living Things Require […]
