Oxygen Delivery Devices Fact: Oxygen is a medication ordered by the physician Humans naturally breath 21% oxygen from the room air Normal oxygen saturation is 95-99% Clinically‚ if not receiving oxygen therapy‚ a patient on room air should have pulse ox reading of at least 92% or above Definitions: Pulse oximeter – a non-invasive way to monitor the percentage of oxygen carried in blood. Hypoxia – Impaired level of oxygen in the body Hypoxic - Lack of oxygen in the tissues‚ tissue starved

Fish cold-blooded‚ limbless‚ completely aquatic vertebrates‚ having gills‚ commonly fins‚ and typically elongated torpedo-shaped body mostly covered with scales. Fish are usually grouped into four classes‚ three living (Agnatha‚ Chondrichthyes‚ and Osteichthyes) and one extinct (Placodermi): 1. Agnatha‚ the primitive jawless fishes‚ including the cyclostomes (lampreys and hagfishes) and extinct armoured fishes known as ostracoderms‚ none of which has gill arches (bony frames for the gills);

Yellow Fish Ambai’s “Yellow Fish” is a short story about a woman’s leisure on the beach and her discovery of a fish. She watches the fishermen return to shore with their catches and sort through them‚ she spots an unwanted‚ helpless‚ yellow fish thrown away on the sand. The author characterizes the narrator’s compassion as she attempts to help return the fish to the sea‚ restoring its life. In doing so‚ we discover the narrator’s underlying reason in assisting the fish. The author indirectly

The Fish by Elizabeth Bishop Bishop uses literary devices‚ especially similes‚ metaphors‚ tone‚ and imagery to convey her theme of admiration for survivors of life’s difficult battles‚ in this case the fish‚ although at first she failed to admire and appreciate the fish. Bishop also doesn’t realize how beautiful the fish is at first‚ but she eventually finds beauty in the fish. Bishop’s tone of aloofness in lines 5-10 shows that first she is disappointed in what she thought was a big catch.

Report: Ventilation and Oxygen Consumption in Fish Methods: The lab consists of two experiments repeated over a period one hour with fifteen minutes interval‚ in order to determine the effect of weight and temperature on ventilation and oxygen consumption of Carassius auratus‚ commonly known as goldfish. Each experiment was carried out by five groups. Measurement of ventilation was determined by recording operculum movement of the fish. Oxygen consumption was measured using oxygen probes. Experiment-1:

Fish have been a protein source throughout history. Early fishing primarily involved individuals capturing fish near their communities for consumption or trade. Ships gave fishers access to ocean-based fisheries. Commercial fishing became industrialized by the late nineteenth century‚ as technological innovations helped locate‚ catch‚ and process fish. In addition to fish living in natural freshwater or saltwater fisheries‚ fish cultivated in fish farms ’ ponds or tanks represented approximately
