Vital Signs: RespirationVital Signs: Respiration
• Normal respiration is 8 - 16 Normal respiration is 8 - 16 breaths per minutebreaths per minute
• To determine watch the To determine watch the nostrils or flanksnostrils or flanks
• Nostrils flare and contract Nostrils flare and contract with each breathwith each breath
• The respiration rate should The respiration rate should NOT exceed the heart rateNOT exceed the heart rate

Pulse/Respiration RatioPulse/Respiration Ratio
• Normal Ratio – 4:2 or 2:1Normal Ratio – 4:2 or 2:1
• A more significant measure of stress A more significant measure of stress than each of the actual figures alonethan each of the actual figures alone

Vital Signs: Gut SoundsVital Signs: Gut Sounds
• Gut sounds can help you Gut sounds can help you diagnose a sick horsediagnose a sick horse
• Caused by the normal Caused by the normal contracting and relaxing contracting and relaxing movements of the digestive tract movements of the digestive tract during the digestion processduring the digestion process
• Place an ear on the flank area or Place an ear on the flank area or use a stethoscopeuse a stethoscope
• Abnormal- Absence of gut Abnormal- Absence of gut sounds!sounds!

Vital Signs: Mucosal ColorVital Signs: Mucosal Color
• Indicator of blood circulationIndicator of blood circulation
• Several mucous membranes Several mucous membranes can be checked: the inner lips can be checked: the inner lips and gums, inside the vulva and and gums, inside the vulva and nostrils –should be moist and nostrils –should be moist and pinkpink
• Determine capillary refill time Determine capillary refill time by pressing your thumb on the by pressing your thumb on the horse’s gum and then releasing horse’s gum and then releasing itit
• It should take ~2 seconds for It should take ~2 seconds for the blood and normal color to the blood and normal color to return to the areareturn to the area
